The future with a frugal and broke Superpower

Ad Support : Nano Technology   Netbook    Technology News    Computer Software

Thomas Friedman discusses the effect of the world’s only superpower getting weighed down with a lot of debt

* “The Frugal Superpower: America’s Global Leadership in a Cash-Strapped Era” is the title of a new book by Michael Mandelbaum, the Johns Hopkins University foreign policy expert

* U.S. power has been the key force maintaining global stability, and providing global governance, for the last 70 years. That role will not disappear, but it will almost certainly shrink.

Great powers have retrenched before: Britain for instance. But, as Mandelbaum notes, “When Britain could no longer provide global governance, the United States stepped in to replace it. No country now stands ready to replace the United States, so the loss to international peace and prosperity has the potential to be greater as America pulls back than when Britain did.”

After all, Europe is rich but wimpy. China is rich nationally but still dirt poor on a per capita basis and, therefore, will be compelled to remain focused inwardly and regionally. Russia, drunk on oil, can cause trouble but not project power. “Therefore, the world will be a more disorderly and dangerous place,” Mandelbaum predicts.

After Gingerbread Google Android 3.0 there will be Honeycomb Google Android 3.5 in 2011

Samsung is already hard at work on next-generation tablets that will run on Google’s upcoming Android 3.5 Honeycomb platform.

Unlike Gingerbread, which is supposed to take Android 2.2 [also known as FroYo, short for Frozen Yoghurt] all the way up to version 3.0 and promises to include a radically new user interface that takes full advantage of the advanced graphics rendering capabilities in upcoming smartphones, Honeycomb is supposed to be to Gingerbread what FroYo was to Éclair.

Honeycomb is expected nothing more than a point release. Intmobile believes that Google’s Chrome OS will be what powers tablets and that Android 3.X will eventually trickle down into manufacteres midrange portfolios.

UCSD robotics lab head Thomas Bewley interview by Sander Olson

Ad Support : Nano Technology   Netbook    Technology News    Computer Software

Here is the Thomas Bewley interview by Sander Olson. Dr. Bewley heads the Coordinated Robotics Lab at the University of California San Diego. The UCSD lab's specialty is using feedback control to impart stability to robots. Dr. Bewley is an expert on simulation, optimization, and control issues relating to robotics, and he is currently writing a textbook on this subject. Dr. Bewley's lab is improving their robots at a rapid pace, and is developing updated versions of robots every year.

Question: You lead the Coordinated Robotics Lab at the University of California, San Diego (UCSD). What makes this lab unique?
Answer: The Coordinated Robotics Lab is fundamentally a dynamics and control shop that does robotics; most other such labs are robotics shops that sometimes do control. We emphasize up front the modeling and control of dynamically unstable systems – we have found that creative, minimalist robotic designs which sacrifice open-loop stability can often achieve greatly enhanced maneuverability. We endeavor to create small, minimalist robots that can overcome large, complex obstacles via clever leveraging of advanced feedback control strategies.

(e) Characteristic I symmetric and II-III antisymmetric modes of excitation associated with the absorption resonances for asymmetries = 1/7 and 1. The plotted field distributions correspond to excitation wavelengths of 820, 1025 and 1200 nm, respectively.

A combinatorial approach to metamaterials discovery has been developed to test dozens of metamaterial combinations at one time.

We report a high through-put combinatorial approach to photonic metamaterial optimization. The new approach is based on parallel synthesis and consecutive optical characterization of large numbers of spatially addressable nano-fabricated metamaterial samples (libraries) with quasi-continuous variation of design parameters under real manufacturing conditions. We illustrate this method for Fano-resonance plasmonic nanostructures arriving at explicit recipes for high quality factors needed for switching and sensing applications.

Combinatorial chemistry is used to test thousands of different but structurally related molecules to speed drug discovery and now this related technique will speed up the discovery of metamaterials with unusual electromagnetic properties.

Selective androgen receptor modulator (SARM) proving to be an effective yet safe steroid

Ad Support : Nano Technology   Netbook       Computer Software

GTx, Inc. (Nasdaq: GTXI) announced in June 2010 that Ostarine™ (GTx-024, formerly MK-2866) increased lean body mass and leg press strength in a head to head study evaluating Ostarine and another selective androgen receptor modulator (SARM), MK-3984, in postmenopausal women.

This was the third Ostarine clinical study that measured lean body mass and physical performance endpoints, and Ostarine has consistently demonstrated the ability to increase muscle mass and strength.

After 12 weeks of treatment in post menopausal women, Ostarine 3 mg and MK-3984 significantly increased total lean body mass. Compared to placebo, mean differences from baseline for lean body mass were observed with increases of 1.54 kg (about 3.4 pounds) for both Ostarine 3 mg and 50 mg of MK-3984 and an increase of 1.74 kg (3.8 pounds) for 125 mg of MK-3984.

Mean leg muscle strength at 12 weeks for Ostarine 3 mg treated subjects increased by 22 pounds from baseline. Old women were able to increase their leg press by 22 pounds.

GTx is pursuing a partner company to bring this to market to treat muscle wasting related to cancer.

Real Sarm steroids have been available online since 2009.

Myostatin inhibitors are being pursued as another safe method to treat muscle loss.

Mobile charging stations for electric and plug in hybrid cars

Ad Support : Nano Technology   Netbook    Technology News    Computer Software

New Scientist magazine reports that Zafer Sahinoglu at the Mitsubishi Electric Research Laboratories in Cambridge, Massachusetts, are developing a network of portable charging stations, which can be moved to wherever the demand for recharging is greatest.

To determine where the stations are needed, in-car sensors would monitor the level of charge in the battery and periodically report this to a central operations centre, which would flag areas where most cars run low on juice. The stations can then be deployed wherever the low-charge "hotspots" are at that time. Just five mobile stations would be needed to cover 100 electric cars on a 100-kilometre stretch of highway, the team says.

Imec presented several large-area silicon solar cells with a conversion efficiency above 19%. Two types of cells were realized namely with Ag-screenprinted contacts and plated Cu-contacts. Efficiencies of cells with screenprinted contacts were up to 19.1% whereas 19.4% was obtained with Cu-plated contacts. These high efficiencies were obtained thanks to several factors amongst which a combination of improved texturization and optimized firing conditions. The results were achieved on large-area cells (148cm^2 which is 22.94 square inches. About 6 inches by 4 inches) with 170µm thickness, proving the industrial viability of the process.

Canada, Scandinavia, Russia and the northern United States Will Thrive in Globally Warmer Future

Ad Support : Nano Technology   Netbook    Technology News    Computer Software

UCLA predicts that global warming will have positive economic effects for Canada, Scandinavia, Russia and the northern United States.

Laurence C. Smith writes in "The World in 2050: Four Forces Shaping Civilization's Northern Future" (Dutton Books), scheduled for publication Sept. 23. 2010.

While wreaking havoc on the environment, global warming will liberate a treasure trove of oil, gas, water and other natural resources previously locked in the frozen north, enriching residents and attracting newcomers, according to Smith. And these resources will pour from northern rim countries — or NORCs, as Smith calls them — precisely at a time when natural resources elsewhere are becoming critically depleted, making them all the more valuable.


Car Ownership in China will be over 200 million in 2020

Ad Support : Nano Technology   Netbook    Technology News    Computer Software

China's car ownership will be over 200 million in 2020. Car sales in China rose 45 percent in 2009 to 13.79 million units. There are about 76 million cars in China at the end of 2009.

It is more likely that China will add 15-25 million cars per year from 2010-2020. So it is more likley that China will have 225 to 300 million cars by 2020.

Clearly it would be best if as many of those cars as possible were very light electric vehicles.

Concord Coalitions August 2010 Plausible Budget Baseline shows $15.2 trillion in Federal Deficits from 2010-2020


The Concord Baseline makes some key assumption changes to the CBO baseline. CBO is required to assume that congressional appropriations continue increasing only at the rate of inflation for the 10 year baseline.

They also extend emergency supplemental at their "current" level plus inflation over the duration of the baseline. For tax legislation, they assume current law will govern--so if there are tax cuts that have sunsets (as the 2001 and 2003 tax cuts have), CBO is required to project revenues assuming the tax cuts expire as written in the legislation. They also project economic growth in a very conservative fashion--they do not try to anticipate major changes in the economy, either recessions or accelerations.

Currently neither the Democrats or Republicans are proposing to eliminate the Bush tax cuts completely. Obama is proposing to continue $2 trillion of the Bush tax reductions out of a total of about $2.7 trillion (lower taxes over the 2010-2020 decade). There are some Tea Partiers, Alan Greenspan and few others who oppose extension of the tax cuts.

On the opposite end is Paul Krugman, who advocates running the national debt to $30 trillion in order to replicate a non-war spending equivalent of World war 2

It will take a change from historically government budget trends to actually reduce the US deficit below $1 trillion per year again.

Germany Extending Some Nuclear Plants by Eight Years and Others by Fourteen Years

Ad Support : Nano Technology   Netbook    Technology News    Computer Software

No German reactor are now be expected to shut before 2016. The next five pre-1980 reactors could close by 2020. Eleven further units will get 14 more years, with the last to operate being Neckarwestheim 2 - due for closure in 2036.

T
here will be a tax of €145 ($186) per gram of nuclear fuel, which works out at around €2.3 billion ($2.9 billion) per year. This will be paid into Germany's central budget for six years to aid austerity measures. It is seen as notionally supporting the costs of radioactive waste management work at Asse.

German nuclear utilities will also be called upon to make annual payments of €300 million ($386 million) in 2011 and 2012 to support renewable development, with this lowering to €200 million ($257 million) for the period to 2016. Beyond that, there is to be a tax on every megawatt-hour of nuclear energy produced that will be placed in a 'renewable fund'. Sources said this would be less than the tax on nuclear fuel.

Eric Drexler, Ralph Merkle or Robert Freitas Are not to Blame When Billions spent on Ordinary Chemistry Was called Nanotechnology Work- You Got What You Paid For

Again there are people complaining that the vision of Eric Drexler was not realized after 25 years since he wrote Engines of Creation and other research papers on molecular nanotechnology.

However, almost no money was spent funding the research and development of molecular nanotechnology. Significant amounts of money were devoted to mostly relabeled chemistry starting in November, 2003.

Locklin (link to his site removed, since he is a flamebaiting troll) gets facts wrong and the target of his outrage is totally misdirected. The billions for NNI were hijacked for the falsely labeled nanotech starting in 2003. It is idiotic to blame Drexler, Merkle, Freitas when they did not get the money.

Locklin and people like him ignored what has been happening for eight years and allowed the funding to be hijacked for what they do not believe is nanotechnology. Now they have stain proof pants buyers remorse and are not satisfied with carbon nanotubes and the other non-molecular nanotech research. The proper response is to write to congressmen and senators to direct NNI appropriations into an actual effort to develop molecular nanotechnology. If after actually getting funding and work for 10-25 years, then there could be some comparison of progress expected versus results delivered. For now the results match the effort that has been performed. There are very little results from almost no societal effort. Your team did not do any laps in the Daytona 500 because you did not buy a car for your team or pay for an entry fee. Whining about it now, makes me ask - Where the hell have you been for the last eight years ? When you buy your SUV from Ford Motors do you send your complaints to Porsche or DeLorean about the race car you did not buy ?

This is what went down in 2003

Drexler presented his theories to Congress in 1992. He testified before the Senate Subcommittee on Science, Technology, and Space during a hearing about "new technologies for a sustainable world." Subcommittee chair Al Gore declared his enthusiasm and vowed to fund exploratory research.

Under attack from all sides, Drexler was nonetheless poised for victory in Washington. After years of lobbying by the Foresight Institute, in May 2003 the House passed the Nanotechnology Research and Development Act by a lopsided vote of 405 to 19. The bill contained a provision - written by California representative Brad Sherman, a Drexler supporter who had spoken at Foresight's annual conference the previous year - calling for a study to "develop, insofar as possible, a consensus on whether molecular manufacturing is technically feasible." If the technology was deemed feasible, the study would find "the estimated time frame in which molecular manufacturing may be possible on a commercial scale; and recommendations for a research agenda necessary to achieve this result."

With this language, Congress was on the verge of making Drexler's dream a reality. But by November - five months later - the provision had vanished from the legislation.

What turned the tide on Capitol Hill? Drexler's ideas had always been outlandish and his political skills underdeveloped. That combination became an Achilles' heel as opposition emerged from two quarters. First, a group called the NanoBusiness Alliance entered the fray. Formed in October 2001, the alliance wasn't interested in anything as starry-eyed or scary as self-replicating molecular assemblers; it wanted to sell newfangled products like "nanotech" suntan lotion, ski wax, and paint. One of the founders, venture capitalist F. Mark Modzelewski, was a notorious opponent of Drexlerian notions; in a later email exchange with blogger and nanotech booster Glenn Reynolds, he likened Drexler's theories to "a wino's claims on skid row that bugs are crawling under his skin."

Meanwhile, support for Drexler's ideas softened elsewhere in Washington. The White House's Office of Science and Technology Policy worried that fears whipped up by the likes of Crichton and Joy would turn the public against nanotech, just as similar scares had fueled opposition to GM foods and nuclear power. As New Hampshire's John Sununu remarked on the Senate floor, "some people have expressed concern that nanotechnology will lead to a superrace of humans or a situation where nanomachines attack or even dominate human beings."

Molecular manufacturing is a "loaded term," a Senate staffer says. "It upsets a lot of people."

The sponsors of the House bill were more interested in making sure it got through the Senate than they were in preserving funding for Drexler's ideas. Thus, when House and Senate staff members met to discuss their respective bills, they scuttled the molecular manufacturing study. In the Senate version, Arizona's John McCain introduced an "amendment in the nature of a substitute" in which the provision no longer appeared.

The watered-down bill was passed by the unanimous consent of the Senate on November 18 and signed into law by Bush on December 3. During the ceremony, Richard Smalley stood at the president's side


So if Scott Locklin is disappointed that there has not been the development of molecular nanotechnology, then perhaps he should blame the NanoBusiness Alliance and Richard Smalley, because almost no effort was made to fund anything like molecular nanotechnology. Molecular nanotechnology was explicitly excluded from funding.

So if the world bought a future nanotech - it was the nanotech of stuff smaller than 100 nanometers and the money was guided to Rice University and other Universities with Chemistry and Microbiology departments that got the grants and organizations linked to the Nanobusiness Alliance.

Eric Drexler wrote the first molecular nanotechnology books and told people to fund something else. The politicians and businesses mostly did not listen or do what he told them or the projects of Ralph Merkle and Robert Freitas.

Neutron Rich Matter

Arxiv - Neutron rich matter, neutron stars, and their crusts (10 age pdf)

(H/t Adam Crowl
Neutron rich matter is at the heart of many fundamental questions in Nuclear Physics and Astrophysics. What are the high density phases of QCD? Where did the chemical elements come from? What is the structure of many compact and energetic objects in the heavens, and what determines their electromagnetic, neutrino, and gravitational-wave radiations? Moreover, neutron rich matter is being studied with an extraordinary variety of new tools such as Facility for Rare Isotope Beams (FRIB) and the Laser Interferometer Gravitational Wave Observatory (LIGO). We describe the Lead Radius Experiment (PREX) that is using parity violation to measure the neutron radius in 208Pb. This has important implications for neutron stars and their crusts. Using large scale molecular dynamics, we model the formation of solids in both white dwarfs and neutron stars. We nd neutron star crust to be the strongest material known, some 10 billion times stronger than steel. It can support mountains on rotating neutron stars large enough to generate detectable gravitational waves. Finally, we describe a new equation of state for supernova and neutron star merger simulations based on the Virial expansion at low densities, and large scale relativistic mean eld calculations.

There is a very interesting relationship between the neutron radius of 208Pb, of order 6 femtometers, and the radius of a neutron star, of order 10 km. This involves a breathtaking extrapolation of 18 orders of magnitude in size, or 55 orders of magnitude in mass.

Harvard makes auto differential like device one million times smaller for Micro UAVs

Engineers at Harvard University have created a millionth-scale automobile differential to govern the flight of minuscule aerial robots that could someday be used to probe environmental hazards, forest fires, and other places too perilous for people.. The device is literally one one-millionth the size of what you’d find in your car.

Their new approach is the first to passively balance the aerodynamic forces encountered by these miniature flying devices, letting their wings flap asymmetrically in response to gusts of wind, wing damage, and other real-world impediments.

“The drivetrain for an aerial microrobot shares many characteristics with a two-wheel-drive automobile,” said Pratheev S. Sreetharan, a graduate student in Harvard's School of Engineering and Applied Sciences. “Both deliver power from a single source to a pair of wheels or wings. But our PARITy differential generates torques up to 10 million times smaller than in a car, is 5 millimeters long, and weighs about one-hundredth of a gram.” PARITy is an acronym for Passive Aeromechanical Regulation of Imbalanced Torques.

China's building a high speed rail economy and could achieve a 1 to 1.2 billion person single city effect by 2040

Ad Support : Nano Technology   Netbook    Technology News    Computer Software

China has become the country with the fastest development, most complete systematic technologies, strongest assembly capacity, the greatest length of track, highest operational speed and the largest project scale of high-speed railways in the world. High speed rail seems to be providing a 1.0 to 1.5% annual GDP boost to regional economies. China could use low pressure maglev to create a 1 to 1.2 billion person megacity by 2040 and a 1.4 billion person megacity by 2050. A large number of high passenger and freight capacity maglev with 1500-2000 mile per hour speed could connect all of the cities in China by 2050. A UN report discusses the merging of cities into mega-regions and the is the largest megaregion is Hong Kong-Shenhzen-Guangzhou region in China, home to about 120 million people already. Super high speed rail will enable dense cities to physically connect for more productivity and economic growth. If China proceeds down this path and achieves success there will be high speed rail links to the European high speed rail network, Japans high speed rail network and then connections across to the Americas.

China has put 355 multiple-unit trains into operation, including 234 trains that can reach 250 kilometers per hour and 121 trains that can reach 350 kilometers per hour

China's high-speed railways are mainly in the three large economic zones, the Yangtze River Delta, the Pearl River Delta and the Beijing-Tianjin-Hebei economic zone. Just in 2009, the average local GDP of the three zones had increased by as high as 10 percent, 1.7 percentage points higher than the growth rate of China's total GDP.

In the same year, the GDP of the three zones accounted for 44 percent of the GDP of China, up three percentage points compared to that of 2008. Experts believe that China's high-speed railways have become a booster for China's regional economic integration.

Role of Kinetic Factors in Chemical Vapor Deposition Synthesis of Uniform Large Area Graphene Using Copper Catalyst

Ad Support : Nano Technology   Netbook    Technology News    Computer Software

This is research towards make large area graphene using copper catalyst with chemical vapor deposition

In this article, the role of kinetics, in particular, the pressure of the reaction chamber in the chemical vapor deposition (CVD) synthesis of graphene using low carbon solid solubility catalysts (Cu), on both the large area thickness uniformity and the defect density are presented. Although the thermodynamics of the synthesis system remains the same, based on whether the process is performed at atmospheric pressure (AP), low pressure (LP) (0.1−1 Torr) or under ultrahigh vacuum (UHV) conditions, the kinetics of the growth phenomenon are different, leading to a variation in the uniformity of the resulting graphene growth over large areas (wafer scale). The kinetic models for APCVD and LPCVD are discussed, thereby providing insight for understanding the differences between APCVD vs LPCVD/UHVCVD graphene syntheses. Interestingly, graphene syntheses using a Cu catalyst in APCVD processes at higher methane concentrations revealed that the growth is not self-limiting, which is in contrast to previous observations for the LPCVD case. Additionally, nanoribbons and nanostrips with widths ranging from 20 to 100 nm were also observed on the APCVD grown graphene. Interactions between graphene nanofeatures (edges, folds) and the contaminant metal nanoparticles from the Cu etchant were observed, suggesting that these samples could potentially be employed to investigate the chemical reactivity of single molecules, DNA, and nanoparticles with monolayer graphene.

Graphene Transistors Should reach 700-1400 Gigahertz with 45-100 nanometer channels

Nanoletters - Sub-100 nm Channel Length Graphene Transistors

Here we report high-performance sub-100 nm channel length graphene transistors fabricated using a self-aligned approach. The graphene transistors are fabricated using a highly doped GaN nanowire as the local gate with the source and drain electrodes defined through a self-aligned process and the channel length defined by the nanowire size. This fabrication approach allows the preservation of the high carrier mobility in graphene and ensures nearly perfect alignment between source, drain, and gate electrodes. It therefore affords transistor performance not previously possible. Graphene transistors with 45−100 nm channel lengths have been fabricated with the scaled transconductance exceeding 2 mS/μm, comparable to the best performed high electron mobility transistors with similar channel lengths. Analysis of and the device characteristics gives a transit time of 120−220 fs and the projected intrinsic cutoff frequency (fT) reaching 700−1400 GHz. This study demonstrates the exciting potential of graphene based electronics in terahertz electronics.

We report on a means to tune the topographical and electrical properties of reduced GO (rGO) with nanoscopic resolution by local thermal reduction of GO with a heated atomic force microscope tip. The rGO regions are up to four orders of magnitude more conductive than pristine GO. No sign of tip wear or sample tearing was observed. Variably conductive nanoribbons with dimensions down to 12 nanometers could be produced in oxidized epitaxial graphene films in a single step that is clean, rapid, and reliable.

Researchers at the California Institute of Technology (Caltech) have devised a new technique—using a sheet of carbon just one atom thick—to visualize the structure of molecules. The technique, which was used to obtain the first direct images of how water coats surfaces at room temperature, can also be used to image a potentially unlimited number of other molecules, including antibodies and other biomolecules

RNA Interference Success Versus Cancer

Popular Science reports that biotech company Alnylam announced in June that its drug ALN-VSP cut off blood flow to 62 percent of liver-cancer tumors in those 19 patients, by triggering a rarely used defense mechanism in the body to silence cancerous genes. Whereas conventional drugs stop disease-causing proteins, ALN-VSP uses RNA interference (RNAi) therapy to stop cells from making proteins in the first place, a tactic that could work for just about any disease. “Imagine that your kitchen floods,” says biochemist and Alnylam CEO John Maraganore. “Today’s medicines mop it up. RNAi technology turns off the faucet.”

Novel Lipid Nanoparticles enabled systematic RNAi with one times more potency.

The Speculist has coverage

Alnylam Pharmaceuticals, Inc. made a total of 16 oral presentations at the American Chemical Society (ACS) Fall 2010 240th National Meeting & Exposition in Boston from August 22-26, 2010

Notable highlights from their presentations include results showing superior properties of canonical siRNAs compared with so-called 'dicer substrate' constructs, the application of 'click chemistry' approaches to the synthesis of siRNA conjugates, and the synthesis of novel cationic lipids for systemic delivery of siRNAs with lipid nanoparticles

UCSF unveils model for implantable artificial kidney to replace dialysis

Ad Support : Nano Technology   Netbook    Technology News    Computer Software
A model of the implantable bioartificial kidney shows the two-stage system. Thousands of nanoscale filters remove toxins from the blood, while a BioCartridge of renal tubule cells mimics the metabolic and water-balance roles of the human kidney.
UCSF researchers today unveiled a prototype model of the first implantable artificial kidney, in a development that one day could eliminate the need for dialysis. The device, which would include thousands of microscopic filters as well as a bioreactor to mimic the metabolic and water-balancing roles of a real kidney, is being developed in a collaborative effort by engineers, biologists and physicians nationwide, led by Shuvo Roy, PhD, in the UCSF Department of Bioengineering and Therapeutic Sciences.

The team has established the feasibility of an implantable model in animal models and plans to be ready for clinical trials in five to seven years.

End-stage renal disease, or chronic kidney failure, affects more than 500,000 people per year in the United States alone, and currently is only fully treated with a kidney transplant. That number has been rising between 5-7 percent per year, Roy said, in part because of the kidney damage associated with diabetes and hypertension.

Yet transplants are difficult to obtain: a mere 17,000 donated kidneys were available for transplant last year, while the number of patients on the transplant waiting list currently exceeds 85,000, according to the Organ Procurement ant Transplant Network.

Roughly 350,000 patients are reliant on kidney dialysis, Roy explained, which comes at a tremendous cost. The Medicare system alone spends $25 billion on treatments for kidney failure – more than 6 percent of the total budget – while the disease affects only 1 percent of Medicare recipients

Robots Getting out of the Lab and Pick up Garbage

Ad Support : Nano Technology   Netbook    Technology News    Computer Software

Call up DustCart from your cell phone, and it will roll along on its Segway base to your home, text you to let you know it has arrived, and thrust forth a receptacle for your garbage, which it then shuttles back to a dumping station. (Dustbot can haul 70 pounds of trash at once, and its battery lets it travel 10 miles before a charge.

Many residents of Peccioli live in old streets too narrow for an old-fashioned garbage truck to navigate. So the town decided to give DustCart a real-world audition this summer. A pair of DustCarts served some one hundred homes for a period of months.
Dustbot is summoned by phone call or SMS, and uses GPS to automatically make its way to the customer, collect the rubbish, and take it to a dustbin. In addition, the Dustbots carry environmental sensors to monitor the pollution levels over, for example, a pedestrian area. The Dustbot system, consisting of the DustCart and the DustClean robots, is designed to work in tight urban areas where large trucks find it difficult to operate.

Alphabet Energy has a Thermoelectric Chip that Could convert Waste Heat to Electricity for less than $1 per watt

Ad Support : Nano Technology   Netbook    Technology News    Computer Software

Alphabet Energy is a startup that has a a thermoelectric chip that can be inserted into any exhaust flue or engine to convert heat into electrical power.

lphabet says its innovation is in both the choice of material and proprietary technology that gives it low thermal conductivity, and makes it highly suitable for both scale and miniaturization—for use in small devices as well as in large factory flues. The device is connected by wire to the plant’s electrical system or to the grid, so it feeds in power converted by heat in real time. Only a year old, Alphabet has the ambitious goal of leading what it believes could be a $200 billion global market for technology at the core of waste heat recovery systems.

Alphabet says its chip is produced in a way that’s similar to how microchips for electronic devices are made. Tapping into the semiconductor industry's economies of scale will allow the company to slash costs enough to install its systems for "well under $1 a watt," said Scullin, compared to installation costs double or triple that amount for some competing waste heat recapture systems.

Depending on the flow rate, chemical composition, and temperatures of the exhaust coming out of an industrial flue, he said, Alphabet's technology could deliver a payback time of two to four years for a manufacturer.

According to Scullin, Alphabet plans to complete a pilot installation at an industrial facility with a large waste heat source next year, with an aim of winning commercial customers by 2012. So far, most of the potential customers in discussion with Alphabet are multinational corporations
Recycled Energy Development (RED) aims to retrofit large factories to convert waste heat into electricity and useful thermal energy (typically steam or hot water), and then sell it to the grid, host, or nearby facilities.

Femtotech Speculation

Ad Support : Nano Technology   Netbook    Technology News    Computer Software

Artificial intelligence researcher Hugo deGaris has speculated on Femtotechnology.

He has considered -
a) Nucleon Chemistry on the surface of neutron stars?
b) Stranglets (agglomerations of S(trange) quarks)?

At Hplusmagazine Hugo deGaris again mentions femtotechnology but does not provide any more progress to a path to achieving it. He also discusses artificial intelligence and a conflict that he expects between those who fully embrace greater than human artificial intelligence and those who do not.

Femtotech has been examined more closely by Bolonkin who has considered getting neutron sources and attempting to contain and control them sufficiently to generate femtoscale matter (custom nuclei).

Various other means are under consideration for generation of AB-Matter, what is certain however is that once the first small amounts have been achieved, larger and larger amounts will be produced with ever increasing ease. Consider for example, that once we have achieved the ability to make a solid AB-Matter film (a sliced plane through a solid block of AB-matter) and then developed the ability to place holes with precision through it one nucleon wide, a modified extrusion technique may produce AB-Matter strings (thin fiber), by passage of conventional matter in gas, liquid or solid state through the AB-Matter matrix (mask). This would be a ‘femto-die’ as Joseph Friedlander of Shave Shomron, Israel, has labeled it. Re-assembling these strings with perfect precision and alignment would produce more AB-matter film; leaving deliberate gaps would reproduce the ‘holes’ in the initial ‘femto-die’.

The developing of femtotechnology is easier, in one sense, than the developing of fully controllable nanotechnology because we have only three main particles (protons, neutrons, their ready combination of nuclei 2D, 3T, 4He and electrons) as construction material and developed methods of their energy control, focusing and direction.

The Samsung Galaxy Tab features a 7-inch LCD display and Google's latest Android 2.2 operating system, which allows for access to Flash videos and the Android app market. Samsung will also provide its own set of apps for the device.

The ‘Readers Hub,’ Samsung’s unique e-reading application, provides easy access to a vast digital library – from classical literature to the latest bestsellers and reference materials. At the same time, Samsung unveils ‘Media Hub,’ a gateway to a world of films and videos, and ‘Music Hub,’ an application giving access to a wide range of music tunes.


The Samsung Galaxy Tab is expected to sell for 200 to 300 dollars in 16 Gigabyte and 32 gigabyte versions and can also take up to 32 gigabytes of microSD. It has a 3 megapixel and a 1.3 megapixel camera. The battery should last for 7 hours of video playing.

This looks like it crushes the Apple iPad on features. The Apple iPad does have a larger screen and a larger set of available applications but it does not have the phone capabilities and the android marketplace of applications is very large. I am definitely more interested in the Samsung Galaxy Tab than the Apple iPad.

Samsung recently announced that they have sold one million of the Samsung Galaxy S smartphone in 45 days of availability in the USA.
The high end smartphone boasts a super-thin form factor with 4-inch Super-AMOLED display and a speedy 1GHz Hummingbird processor.

Samsung aims to record 10 million in sales with its Galaxy S globally. Apple is targeting about 15.8 million iPhone sales in the USA in 2010.

UCLA makes 300 Gigahertz Graphene Transistor and Targets 1 Terahertz

Ad Support : Nano Technology   Netbook    Technology News    Computer Software

University of California Los Angeles researchers have used a nanowire to build a transistor based on graphene.

The resulting field-effect transistor switches at the highest speed reported so far: 300 gigahertz in a device with a channel length (the distance between the source and the drain) of 140 nanometers. That’s roughly twice as fast as the best silicon metal-oxide-semiconductor field-effect transistor of similar proportions and comparable to transistors made of indium phosphide or gallium arsenide, which are expensive compound semiconductors.

The channel length is defined by the diameter of the nanowire, which in the transistors built by Duan’s team was 100 to 300 nm. That’s relatively thick, and Duan would like to get the diameter under 100 nm. He hopes to get to about 50 nm, which would allow him to build devices that could reach terahertz speeds.

Conventional processes for building the electrodes that act as the transistors’ gates, sources, and drains introduces defects into the carbon lattice, slowing down the flow of charge. The UCLA group got around this problem by using a nanoscale wire as both a component of and a template for the transistor.

Large scale, cost-effective stem cell factories able to keep up with demand for new therapies to treat a range of human illnesses are a step closer to reality, thanks to a scientific breakthrough involving researchers at The University of Nottingham.

In a paper published in the September edition of the prestigious journal Nature Materials, a team of Nottingham scientists led by Professor Morgan Alexander in the University’s School of Pharmacy, reveal they have discovered some man-made acrylate polymers which allow stem cells to reproduce while maintaining their pluripotency.

Professor Alexander said: “This is an important breakthrough which could have significant implications for a wide range of stem cell therapies, including cancer, heart failure, muscle damage and a number of neurological disorders such as Parkinson’s and Huntington’s.


Rice University and Privatran silicon oxide circuits are memristors

Memristors made from pure silicon could enable resistive random access memory (ReRAM) that are simpler and cheaper to manufacture than Hewlett-Packard Co.'s titanium-based formulation, according to researchers at Rice University. In collaboration with fabless chip design house PrivaTran Inc. the team demonstrated a proof-of-concept ReRAM that packs only 1-kbit, but which they claim can be scaled beyond the densities of flash.

By carefully crafting the voltage pulses going through it, thin layers of silicon dioxide can be made to change their resistance from near infinite to near zero, according to Rice and PrivaTran (Austin, Texas). SanDisk Corp. in fact has used this phenomenon to create write-once memories, but now Rice and PrivaTran claim to have made the process reversible, thereby enabling pure silicon ReRAMs.

Several Lab on a Chip and microfluidic Advances for more accurate diagnosis in minutes instead of hours or days

Ad Support : Nano Technology   Netbook    Technology News    Computer Software



University of Florida researchers have helped to develop a device that quickly identifies genes and proteins in body fluids — a technique that could make a vital difference to the trauma patients doctors treat.

Previous devices required 4 to 8 milliliters of fluids, the work of a highly skilled technician and several hours to complete analysis.

“We’re getting 100 nanograms of RNA with 0.15 (milliliters) of blood and we’re doing it all in 30 minutes,” said Kenneth Kotz, a research fellow in the department of surgery at Massachusetts General Hospital. “No one’s really ever been able to do this for neutrophils. No one’s been able to demonstrate the speed and the sample quality with these small blood volumes.”

Kotz built the device, which is laced with antibodies that capture the individual cells when a sample of fluid, such as blood or urine, is pumped through it. Nucleic acids or proteins from the cells are then extracted from the cassette, allowing researchers to analyze how specific genes are expressed.

Testing showed the device yielded pure samples of neutrophils, and their gene expression pattern was consistent with results from tests performed in previous studies.

“We’ve identified 63 genes that are differentially expressed,” Moldawer said, “so that when you are admitted to the emergency room after severe trauma, we can hopefully tell with better certainty whether you’re going to have a good or bad outcome (by looking at these genes).”
