Researchers from Institute of Materials Research and Engineering (IMRE), an institute of Singapore's Agency for Science, Technology and Research (A*STAR) have invented new 'smart' biomaterials including a unique hydrogel that has an on-off switch to precisely control its density and a new modular block copolymer that can be tailored to be triggered by specific temperatures.
It sounds like something out of a comic book or a science fiction movie - a living laser - but that is exactly what two investigators at the Wellman Center for Photomedicine at Massachusetts General Hospital have developed. The researchers describe how a single cell genetically engineered to express green fluorescent protein can be used to amplify the light particles called photons into nanosecond-long pulses of laser light.
A new generation of high speed, silicon-based information technology has been brought a step closer by researchers in the Department of Electronic and Electrical Engineering at UCL and the London Centre for Nanotechnology. The team's research provides the first demonstration of an electrically driven, quantum dot laser grown directly on a silicon substrate with a wavelength suitable for use in telecommunications.
With the completion of a successful prototype, engineers at Oregon State University have made a major step toward addressing one of the leading problems in energy use around the world today - the waste of half or more of the energy produced by cars, factories and power plants.
In recent years, UC Santa Barbara scientists showed that they could reproduce a basic superconductor using Einstein's general theory of relativity. Now, using the same theory, they have demonstrated that the Josephson junction could be reproduced.
A team of scientists and engineers led by University of Illinois at Chicago engineering professor Christos Takoudis will use a $475,000 National Science Foundation grant to study ways of building nano-scale solid oxide fuel cells that operate efficiently at intermediate-range temperatures.
Two University of Pennsylvania engineers have proposed the possibility of two-dimensional metamaterials. These one-atom-thick metamaterials could be achieved by controlling the conductivity of sheets of graphene, which is a single layer of carbon atoms.
New research just published in the journal Science by a team of chemists at the University of Georgia and colleagues in Germany shows for the first time that a mechanism called tunneling control may drive chemical reactions in directions unexpected from traditional theories.
