Vitamin C chips Using vitamin C, Rice University has developed a process that turns gold nanorods into small gold nanowires. Nanorods are a type of structure, while nanowires are simply tiny wires. With the technology, Rice is able to produce nanowires with various lengths. These can be used in electronics as well as light-manipulating applications like plasmons. A “plasmon is a quantum o... » read more

Firefly microstructures in LED light bulbs Pennsylvania State University researchers wanted to improve the energy efficiency of commercial light-emitting diode light bulbs to save even more energy. They found the answer in the lantern surface of fireflies. "LED lightbulbs play a key role in clean energy," said Stuart (Shizhuo) Yin, professor of electrical engineering at Penn State. "Overall... » read more

Computed Axial Lithography Lawrence Livermore National Laboratory (LLNL) and the University of California at Berkeley have developed a 3D printing method to produce a new class of polymer parts. The technology, called Computed Axial Lithography (CAL), projects photons on a resin in a vial within a 3D printer. In total, researchers have demonstrated the ability to shine 1,440 different proje... » read more

How things stick together Using a metrology technique called atomic force microscopy (AFM), Brown University has gained more insights into the theory of adhesion or how things stick together. Understanding the theory of adhesion also has some practical applications. It could pave the way towards a new class of MEMS or nanoscale devices. Nanoscale patterning is another potential application.... » read more

Multi-beam litho shakeout The multi-beam e-beam market for lithography applications continues to undergo a shakeout amid technical roadblocks and other issues. Last week, ASML announced that it had acquired the intellectual-property (IP) assets of Mapper Lithography, a Dutch supplier of multi-beam e-beam tools for lithography applications that fell into bankruptcy late last year. As it t... » read more
