By using a variety of materials not commonly associated with MEMS technology, a team from Brigham Young University has created stronger microstructures that can form precise, tall and narrow 3-D shapes - characteristics that were never before possible in MEMS.
Photovoltaic cell efficiency may soon get a big boost, thanks to next-generation antireflection coatings crafted from nanomaterials capable of cutting down on the amount of light reflected away from a cell's surface.
Scientists are using a layering technique developed for microchip manufacturing to build nanoscale 'bowls' that protect miniature metal catalysts from the harsh conditions of biofuel refining. Furthermore, the size, shape, and composition of the nanobowls can easily be tailored to enhance their functionality and specificity.
Scientists have succeeded in creating near-atomically flat silicon, of the orientation used by the electronics industry, in a room temperature reaction. The flat silicon might one day serve as the base for new biological and chemical sensors.
A team of researchers led by Ray Phaneuf, a professor of materials science and engineering at the University of Maryland, College Park, has partnered with The Walters Art Museum in Baltimore to investigate less labor-intensive ways to protect silver artifacts from tarnishing.
Scientists from the National Renewable Energy Laboratory (NREL) have demonstrated the first solar cell with external quantum efficiency (EQE) exceeding 100 percent for photons with energies in the solar range.
Researchers have overcome this problem by an elegant self-assembly technique that produces millions of nanolenses on the basis of metallic nanoparticles in combination with DNA structures. These nanolenses enable 100fold more sensitive detection of even single molecules than previous approaches.
Wissenschaftler an der Technischen Universität Braunschweig, hat nun ein Verfahren entwickelt, bei dem Millionen sogenannter Nanolinsen aus metallischen Nanoteilchen und DNA parallel hergestellt werden. Diese Nanolinsen erlauben es, sogar einzelne Moleküle bis zu einhundertfach genauer zu untersuchen.
The study of materials at extreme conditions took a giant leap forward with the discovery of a way to generate super high pressures without using shock waves whose accompanying heat turns solids to liquid.
