PEDOT:PSS: Improving thermoelectric materials that convert heat to electricity and vice-versa
Thermoelectric materials can be used to turn waste heat into electricity or to provide refrigeration without any liquid coolants, and a research team from the University of Michigan has found a way to nearly double the efficiency ...
Researchers find retinal rods able to detect photon number distribution
Better batteries from waste sulfur
A new chemical process can transform waste sulfur into a lightweight plastic that may improve batteries for electric cars, reports a University of Arizona-led team. The new plastic has other potential uses, ...
Harnessing the potential of quantum tunneling: Transistors without semiconductors
(Phys.org) —For decades, electronic devices have been getting smaller, and smaller, and smaller. It's now possible—even routine—to place millions of transistors on a single silicon chip.
Komaba Group reports sodium ion battery progress
Polymer film that gradually releases DNA coding for viral proteins could offer better alternative to vaccines
Vaccines usually consist of inactivated viruses that prompt the immune system to remember the invader and launch a strong defense if it later encounters the real thing. However, this approach can be too risky ...
Researchers print transistor on nearly transparent nanopaper
Researchers speed up transistors by embedding tunneling field-effect transistor
Unleashing oxygen: 'Superlattice' structure could give a huge boost to oxygen reaction in fuel cells
New research at MIT could dramatically improve the efficiency of fuel cells, which are considered a promising alternative to batteries for powering everything from electronic devices to cars and homes.
Transparent electrode innovation could bring flexible solar cells, transistors, displays
(Phys.org) —Researchers have created a new type of transparent electrode that might find uses in solar cells, flexible displays for computers and consumer electronics and future "optoelectronic" circuits ...
Durable carbon nanotube sensors can be etched with mechanical pencils
Carbon nanotubes offer a powerful new way to detect harmful gases in the environment. However, the methods typically used to build carbon nanotube sensors are hazardous and not suited for large-scale production.
3D printing tiny batteries
(Phys.org) —3D printing can now be used to print lithium-ion microbatteries the size of a grain of sand. The printed microbatteries could supply electricity to tiny devices in fields from medicine to communications, ...
