Highly precise nanostructuring using ultrasound: new procedure to produce porous metals

They are corrosion resistant, mechanically strong and withstand exceedingly high temperatures. With such characteristics, porous metals are generating a growing interest in numerous innovative fields of technology. They are characterised by nanostructured surfaces with pores measuring only a few nanometres in diameter. An international research team has successfully developed a heavy-duty and cost-efficient ultrasound procedure for the design and production of such metallic structures.

New experiment would use quantum effects to perform otherwise intractable calculations

At the Association for Computing Machinery's 43rd Symposium on Theory of Computing in June, associate professor of computer science Scott Aaronson and his graduate student Alex Arkhipov will present a paper describing an experiment that, if it worked, would offer strong evidence that quantum computers can do things that classical computers can't. Although building the experimental apparatus would be difficult, it shouldn't be as difficult as building a fully functional quantum computer.

Nanofabrication tools may make silicon optical chips more accessible

In an effort to make it easier to build inexpensive, next-generation silicon-based electro-optical chips, which allow computers to move information with light and electricity, a University of Washington photonics professor, Dr. Michael Hochberg and his research team are developing design tools and using commercial nanofabrication tools.

Physicists demonstrate coveted 'spin-orbit coupling' in atomic gases

Physicists at the Joint Quantum Institute (JQI), a collaboration of the National Institute of Standards and Technology (NIST) and the University of Maryland-College Park, have for the first time caused a gas of atoms to exhibit an important quantum phenomenon known as spin-orbit coupling. Their technique opens new possibilities for studying and better understanding fundamental physics and has potential applications to quantum computing, next-generation "spintronics" devices and even "atomtronic" devices built from ultracold atoms.

Power of Research: a new online game to inspire the scientists of the future

A new strategy browser game - the "Power of research" - is officially launched. Supported by the European Commission, "Power of Research" has been developed to inspire young Europeans to pursue scientific careers and disseminate interesting up-to-date scientific information. Players assume the role of scientists working in a virtual research environment that replicates the situations that scientists have to deal with in the real world.

'Quantum tuning forks' demonstrate directly coupling of vibrating ions

Physicists at the National Institute of Standards and Technology (NIST) have for the first time coaxed two atoms in separate locations to take turns jiggling back and forth while swapping the smallest measurable units of energy. The technique directly links the motions of two physically separated atoms and might simplify information processing in future quantum computers and simulations.

'A little off the top' helps map cells with submicrometer resolution

To determine if a tissue biopsy reveals the presence of cancer, a histologist often screens for cells with an abnormal appearance or a specific visible trait such as a larger-than-usual nucleus. However, by the time a cancer is physically noticeable, the disease may be in its later stages and more difficult to treat. In an effort to identify the earlier-onset, more subtle chemical changes occurring in a cell heading toward malignancy, researchers have developed a technique that slices off the top of a cell and makes the structures accessible to spectroscopic examination of their chemical "signature."
