(Phys.org) —Although organic materials are often used as semiconductors, such as in organic LEDs and organic transistors, organic materials that have an electrical conductivity as high as that of metals are still very scarce. ...
(Phys.org) —Sometimes mathematical theories have implications that extend far beyond their original purpose. This situation holds true for the four-color theorem, which was originally used by cartographers hundreds of years ...
(Phys.org) —Due to their rapid improvements in a short amount of time, perovskite solar cells have become one of today's most promising up-and-coming photovoltaic technologies. Currently, the record efficiency for a perovskite ...
(Phys.org) —One of the biggest challenges facing rechargeable batteries with lithium (Li) electrodes is the growth of dendrites, which can short-circuit the batteries and cause complete failure. Although dendrites do their ...
(Phys.org) —One of the main components of a factory is the robots that transport and assemble objects of varying shapes and sizes. When scaling down to the micro level, the steel and wiring that these robots are made of ...
(Phys.org) —If you're in the business of cracking codes, it would be pretty difficult to break into a security system that you don't even know is there. That's one of the advantages of molecular keypad locks, whose small ...
(Phys.org) —Methane is the main component of natural gas, as well as a potent greenhouse gas whose levels in the atmosphere have been rising. In a new study, scientists have investigated a way to transform methane into ...
(Phys.org) -- Organic transistors serve as a key component of new flexible, low-cost electronics. Since the organic materials that make up these transistors are what give the transistors their ability to switch and amplify ...
(Phys.org) -- As a rising global population and increasing standard of living drive demand for freshwater, many researchers are developing new techniques to desalinate salt water. Among them is a team of scientists from The ...
(Phys.org) -- Geomag, the popular children's toy, contains small metal spheres that can be magnetically connected with a click to build a variety of towers, bridges, and sculptures. In a new study, scientists have done something ...
