Researchers have discovered a new way in which computers based on quantum physics could beat the performance of classical computers. The work, by researchers based in Singapore and the UK, implies that a Matrix-like simulation of reality would require less memory on a quantum computer than on a classical computer. It also hints at a way to investigate whether a deeper theory lies beneath quantum theory.
Scientists have developed a simple and effective way to reduce the threshold voltage and improve the mobility of pentacene thin film transistors with the commonly-used SiO2 substrate by inserting a thin metal phthalocyanine interlayer (of only ca. 2 nm) between the Au source/drain electrodes and the pentacene active layer.
Researchers from the NIST Center for Nanoscale Science and Technology and the NIST Material Measurement Laboratory have demonstrated that a simpler technique for calibrating lateral sensitivity in an atomic force microscope (AFM) agrees with an earlier method developed at NIST to within 5%.
ETH Zurich physicists, in collaboration with colleagues at universities in Switzerland and abroad, have made a breakthrough in the manufacture of monolithic semiconductor structures on silicon. The new structures are nearly perfect, and likely to revolutionise not only X-ray technology.
In a step toward computers that mimic the parallel processing of complex biological brains, researchers from HRL Laboratories, LLC, and the University of Michigan have built a type of artificial synapse.
It has long been well established that fingerprints can be used to identify people or help convict them of crimes. Things have gone a lot further now: fingerprints can be used to show that a suspect is a smoker, takes drugs, or has handled explosives, among other things. In the journal Angewandte Chemie, Pompi Hazarika and David Russell describe the noteworthy progress that has recently been made.
The College of Nanoscale Science and Engineering (CNSE) is spending a full week in the community, sharing the excitement of nanotechnology with children and teenagers as part of national "NanoDays 2012."
A team of physicists at UC Santa Barbara has seen the light, and it comes in many different colors. By aiming high- and low-frequency laser beams at a semiconductor, the researchers caused electrons to be ripped from their cores, accelerated, and then smashed back into the cores they left behind. This recollision produced multiple frequencies of light simultaneously.
Dr Robert Doubleday, Head of Research at the Centre for Science and Policy at the University of Cambridge, is helping to coordinate a European online debate about developments in nanotechnology. This process of public debate is designed to generate questions about nanotechnology and encourage academics to address some of these questions through research.
Want a see-through cellphone you can wrap around your wrist? Such a thing may be possible before long, according to Rice University chemist James Tour, whose lab has developed transparent, flexible memories using silicon oxide as the active component.
In the United States alone, government and private industry together invest more than $3 billion per year in nanotechnology research and development, and globally the total is much higher. What will be the long-run economic returns from these investments, not only in new jobs and product sales, but also from improvements in sustainability?
Georgia Institute of Technology researchers Philip Shapira and Jan Youtie helped answer that question through research presented March 27th at the International Symposium on Assessing the Economic Impact of Nanotechnology held in Washington, D.C.
