The tiny transistor is the heart of the electronics revolution, and materials scientist have just discovered a way to give the workhorse transistor a big boost, using a new technique to incorporate vanadium oxide, one of a family of materials called functional oxides, into the device.
Researchers have succeeded in building protein gates for artificial nano-vesicles that become transparent only under specific conditions. The gate responds to certain pH values, triggering a reaction and releasing active agents at the desired location.
Catalyst design plays a key role in improving these processes. An international team of scientists has now developed a concept that elegantly correlates geometric and adsorption properties. They validated their approach by designing a new platinum-based catalyst for fuel cell applications.
Bionanotechnologists have developed a new, inexpensive way to make microfluidic devices without using costly materials or cleanroom facilities. The technique, which uses a 3D printer and Lego plastic, is called ESCARGOT.
Bringing closer a mass market for hydrogen-powered cars, researchers are upgrading $0.37/gram molybdenum disulfide, 'molly' for short, to take the place of $1,500/gram catalyst platinum. Unlike gasoline, hydrogen as fuel releases water, not carbon, into the air.
