Converting trash into biofuel may cut CO2 emissions by 80 percentSeptember 30th, 2009 WASHINGTON - Scientists in Singapore and Switzerland have suggested that converting the trash that fills the world's landfills into biofuel could cut global carbon emissions by 80 percent. Biofuels produced from crops have proven controversial because they require an increase in crop production that has its own severe environmental costs.
Scientists develop electrical circuits that run entirely from power in treesSeptember 9th, 2009 WASHINGTON - Scientists have developed electrical circuits that run entirely from power in trees. According to results to be published in an upcoming issue of the Institute of Electrical and Electronics Engineers' Transactions on Nanotechnology, there's enough power in trees for University of Washington (UW) researchers to run an electronic circuit.
Reject watermelon juice can be valuable source of biofuelAugust 26th, 2009 WASHINGTON - In a new research, scientists have shown that the juice of reject watermelons can be efficiently fermented into ethanol, which means that watermelon juice can be a valuable source of biofuel. The research was conducted by Wayne Fish and a team of researchers at the USDA-Agricultural Research Service's South Central Agricultural Research Laboratory in Lane, Oklahoma, US.
Electrical explosion in busy section of downtown DC sends 2 injured workers to hospitalAugust 24th, 2009 2 workers hurt in downtown DC electrical explosionWASHINGTON — Authorities say an explosion in an electrical vault in a busy section of Washington, D.C., has sent two workers to the hospital with injuries. D.C. Deputy Fire Chief Ken Crosswhite says the two men were contract employees working in an outdoor electrical vault when there was an explosion in downtown D.C.'s busy Dupont Circle area.
Scientists boost production of biofuel that could replace gasolineAugust 20th, 2009 WASHINGTON - Engineers at Ohio State University, US, have found a way to double the production of the biofuel butanol, which might someday replace gasoline in automobiles. The process improves on the conventional method for brewing butanol in a bacterial fermentation tank.
New lab-on-a-chip device which runs on musicJuly 23rd, 2009 WASHINGTON - Its music, not electromechanical valves, that controls a novel lab-on-a-chip device designed at the University of Michigan (UM). The new system could significantly simplify the process of conducting experiments in microfluidic devices.
First step achieved in development of tiny biological fuel cellsJune 20th, 2009 Washington, June 20 (ANI): Researchers at the University of Georgia (UGA), US, have achieved the first step in developing biological fuel cells that could power pacemakers, cochlear implants and prosthetic limbs. The technique, which has been described as "a significant breakthrough for nanotechnology", involved the development of a successful way to grow molecular wire brushes that conduct electrical charges.
Soon, memory chips that could bend and twistJune 3rd, 2009 WASHINGTON - The day is not far when electronic memory chips would gain the ability to be bended and twisted, for engineers at the National Institute of Standards and Technology (NIST) have found a way to build a flexible memory component out of inexpensive, readily available materials. Although the new device is not ready to debut in the market, but it holds promise not only because of its potential applications in medicine and other fields, but also because it has the characteristics of a memristor.
Biofuel crops can become invasive pests in tropical areasApril 22nd, 2009 WASHINGTON - In a new research, scientists have concluded that biofuel crops proposed for use in the Hawaiian Islands are two to four times more likely to become invasive pests in Hawaii and other tropical areas when compared to a random sample of other introduced plants. The research was done by scientists with the University of Hawaii Pacific Cooperative Studies Unit, who examined the impact of unregulated planting of biofuel crops for their potential invasiveness and raised concerns about their impacts on Hawaii's environment.
Biofuels could hasten climate changeApril 15th, 2009 WASHINGTON - A new study has found that biofuels can hasten climate change, and it will take more than 75 years for the carbon emissions saved through the use of biofuels to compensate for the carbon lost when biofuel plantations are established on forestlands. If the original habitat was peatland, carbon balance would take more than 600 years.
Higher performance electrical and optical integrated circuits come closer to realityMarch 20th, 2009 WASHINGTON - Scientists at the University of Illinois have moved a step closer to realising higher speed electronics and higher performance electrical and optical integrated circuits, for they have successfully created a microwave signal mixer made from a tunnel-junction transistor laser. The researchers have revealed that their mixing device accepts two electrical inputs, and produces an optical signal that was measured at frequencies of up to 22.7 gigahertz.
Tech students offer device to track calorie burningMarch 13th, 2009 WASHINGTON - Georgia Institute of Technology students have crafted a device that allows individuals to constantly compute the calories they burn - even as they sleep. 'It's a completely converged device,' said Garrett Langley, 21, a senior at the Georgia School of Electrical and Computer Engineering (ECE) who spearheaded the project.
Physicists prove the existence of magnetically charged "spin battery"March 12th, 2009 WASHINGTON - An International team of physicists has been able to prove the existence of a "spin battery", a battery that is "charged" by applying a large magnetic field to nano-magnets in a device called a magnetic tunnel junction (MTJ). Developed by researchers at the University of Miami and at the Universities of Tokyo and Tohoku, in Japan, the new technology is a step towards the creation of computer hard drives with no moving parts, which would be much faster, less expensive and use less energy than current ones.
The HappyHR device that tracks calorie burning, even while sleepingMarch 12th, 2009 WASHINGTON - A team of students at the Georgia Institute of Technology has designed a device that allows individuals to constantly compute the amount of calories they burn - even while sleeping. The device, dubbed HappyHR, is a personal monitor that allows users to measure and compare day-to-day physical and caloric activity.
Researchers find ways of making laser more efficientDecember 22nd, 2008 WASHINGTON - A Princeton-led team of researchers has discovered an entirely new mechanism for making common electronic materials emit laser beams. The finding could lead to lasers that operate more efficiently and at higher temperatures than existing devices, and find applications in environmental monitoring, homeland security, medical diagnostics and other areas that require extremely sensitive detection of different chemicals.
