Physicists at the University of Sydney have brought silicon chips closer to performing all-optical computing and information processing that could overcome the speed limitations intrinsic to electronics, with the first report published of an on-chip all-optical temporal integrator.
Scientists can now peer into the inner workings of catalyst nanoparticles 3,000 times smaller than a human hair within nanoseconds. The findings point the way toward future work that could greatly improve catalyst efficiency in a variety of processes that are crucial to the world's energy security, such as petroleum catalysis and catalyst-based nanomaterial growth for next-generation rechargeable batteries
With hands-on experiences in childhood and adolescence having sparked so many science careers, scientists in Canada are describing a quick, simple, safe, and inexpensive way for kids to participate in making microfluidic devices.
Researchers at Rensselaer Polytechnic Institute have developed a new, ultra-simple method for making layers of gold that measure only billionths of a meter thick. The process, which requires no sophisticated equipment and works on nearly any surface including silicon wafers, could have important implications for nanoelectronics and semiconductor manufacturing.
TU/e researchers want to develop solar cells with an efficiency of over 65 percent by means of nanotechnology. In Southern Europe and North Africa these new solar cells can generate a substantial portion of the European demand for electricity. The Dutch government reserves EUR 1.2 million for the research.
For the very first time, a team of researchers in Germany has introduced quantum dots in fully epitaxial nitride laser structures without the need for hybrid systems - effectively eliminating the cumbersome method of combining different materials from epitaxy and evaporation.
Aris Melissaratos, senior advisor to the president for enterprise development at Johns Hopkins Technology Transfer, will speak at the summer's first Professional Development Seminar hosted by the Johns Hopkins Institute for NanoBioTechnology (INBT) on June 16 at 11 a.m. in Maryland Hall 110.
Molecules in quantum states are very fragile. Scientists have devised a way to separate the molecules into their component parts so that the processor's results can be read from the more easily controllable individual atoms. By using lasers, they were able to break down the molecules without compromising the data encoded in them.
The world's smallest chess board - about the diameter of four human hairs - and a pea-sized microbarbershop were winners in this year's design contest for, respectively, novel and educational microelectromechanical systems (MEMS), held at Sandia National Laboratories in mid May.
Although they could revolutionize a wide range of high-tech products such as computer displays or solar cells, organic materials do not have the same ordered chemical composition as inorganic materials, preventing scientists from using them to their full potential. But newly published research shows how to solve this decades-old conundrum.
A scientist at the U.S. Department of Energy's (DOE) Argonne National Laboratory has created visible-light catalysis, using silver chloride nanowires decorated with gold nanoparticles, that may decompose organic molecules in polluted water.
