A new biomaterial designed for repairing damaged human tissue doesn't wrinkle up when it is stretched. The invention from nanoengineers at the University of California, San Diego marks a significant breakthrough in tissue engineering because it more closely mimics the properties of native human tissue.
Researchers are testing different ways of improving rechargeable batteries for electric vehicles and nanotechnology plays an important role in the development. The aim is to offer batteries that have fast charge and discharge rates as well as high stored energy per mass. This can make electric vehicles a competitive alternative to petrol-powered vehicles.
The TAPPI International Conference on Nanotechnology for Renewable Materials, June 6 - 8, 2011 in Arlington, VA, USA gives scientists the unique forum for focusing on the key issues and technologies that will sustain U. S. manufacturing in the coming decades.
What do potato chips and thin-film solar cells have in common? Both need films that protect them from air and water vapor: the chips in order to stay fresh and crisp; the solar cells in order to have a useful life that is as long as possible.
In new work, a stamp replication process was developed and demonstrated for three different types of imprint molds. Replication relies on sequential patterning method called step and stamp nanoimprint lithography (SSIL).
Imec and its partners in the GaN industrial affiliation program (IIAP) have produced device-quality wafers with GaN/AlGaN layers on 200mm silicon wafers. With these wafers, functional GaN MISHEMTs were processed using standard CMOS tools.
In a new study, researchers quantified for the first time these error-suppressing processes for model nanoelectronic systems and estimated the minimum number of electrons necessary for reliable circuit logic. They found that physical fault-tolerance in transistor circuits suppresses the error rate per electron exponentially, while even the most efficient architectural fault-tolerance system only suppresses the error rate subexponentially.
Scientists at Imperial College London have made the most accurate measurement yet of the shape of the humble electron, finding that it is almost a perfect sphere. The experiment, which spanned more than a decade, suggests that the electron differs from being perfectly round by less than 0.000000000000000000000000001 cm. This means that if the electron was magnified to the size of the solar system, it would still appear spherical to within the width of a human hair.
With every bodily movement - from the blink of an eye to running a marathon - nerve cells transmit signals to muscle cells. To do that, nerve cells rely on tiny molecular motors to transport chemical messengers (neurotransmitters) that excite muscles cells into action. It's a complex process, which scientists are still trying to understand. A new study by Syracuse University researchers has uncovered an important piece of the puzzle.
Thin-film solar cells without added silicon 'bulk' is the new creation of Czech and Swiss researchers and industry actors, who worked together to deliver a product that could deliver greater efficiency.
Until only recently, MEMS devices have been viewed as distant cousins to computer chip technologies and consumer electronics, but with the rapid growth of mobile computing devices like smart phones and tablets, MEMS devices are becoming the indispensable 'eyes and ears' of information technology products.
A wealth of information on recent advances in semiconductor research is now available for free, thanks to an agreement between the National Institute of Standards and Technology (NIST) and the American Institute of Physics (AIP).
A class of decorative, flower-like defects in the nanomaterial graphene could have potentially important effects on the material's already unique electrical and mechanical properties, according to researchers at the National Institute of Standards and Technology (NIST) and Georgia Tech.
