The researchers created a new technology design for field effect transistors, which are basic switching devices in computers and other electronic devices. Those types of transistors also are promising candidates for next generation nanodevices. They can offer better switching behavior for computers and devices compared with traditional field effect transistors.
Perovskite solar cells are currently electrifying the solar cell community. This new, cheap, and easy-to-process material has almost ideal physical properties for converting light into electricity: as it is pitch-black, a very thin layer of less than a thousandth of a millimeter is sufficient to absorb all incident sunlight.
gold nanoparticles, coated with a semiconductor, can produce hydrogen from water over four times more efficiently than other methods – opening the door to improved storage of solar energy and other advances that could boost renewable energy use and combat climate change, according to Rutgers University–New Brunswick researchers.
Carbon nanotubes will replace copper wire in cars and planes to reduce weight and improve fuel efficiency. Carbon will filter our water and tell us more about our lives and bodies through new biometric sensors.
Nanoscale Kirigami has taken off as a field of research in the last few years; the approach is based on the ancient arts of origami (making 3-D shapes by folding paper) and kirigami (which allows cutting as well as folding) but applied to flat materials at the nanoscale, measured in billionths of a meter.
Invigorating the idea of computers based on fluids instead of silicon, researchers at the National Institute of Standards and Technology (NIST) have shown how computational logic operations could be performed in a liquid medium by simulating the trapping of ions (charged atoms) in graphene (a sheet of carbon atoms) floating in saline solution. The scheme might also be used in applications such as water filtration, energy storage or sensor technology.
Researchers uncovered a heterogeneous catalysis strategy that deliberately targets post-C-C coupling reaction intermediates during CO2 electrochemical reduction reaction. It opens avenues to the design of efficient catalysts that selectively produce higher-carbon liquid alcohols.
Electronic textiles could allow a person to control household appliances or computers from a distance simply by touching a wristband or other item of clothing — something that could be particularly helpful for those with limited mobility. Now researchers, reporting in ACS Nano, have developed a new type of electronic textiles that is self-powered, highly sensitive and washable.
