A breakthrough in the design of molecular motors

Researchers from CNRS and the Universite de Bordeaux, in collaboration with a Chinese team, have developed the first molecular piston capable of self-assembly. Their research represents a significant technological advance in the design of molecular motors. Such pistons could, for example, be used to manufacture artificial muscles or create polymers with controllable stiffness.

Revolutionary SERS nanosubstrates for medical tests

Gold-coated substrates of gallium nitride with specifically formed surface, developed by researchers from the Institute of Physical Chemistry of the Polish Academy of Sciences and the Institute of High Pressure Physics of the PAS display worldwide unique properties. Thanks to these new substrates, an extremely sensitive SERS analytical technique, capable of detecting even single molecules, after decades of waiting in specialized laboratories has finally got a chance to widespread and revolutionize medical diagnostics.

Glowing spirals - chemical scaffolds guide living cells into precisely defined three-dimensional patterns

To find our way, we use maps. Cells use "chemical maps" to find the way: they orient themselves by following concentration gradients of attractants or repellants. David H. Gracias and a team at Johns Hopkins University (Baltimore, USA) have now developed a clever new method to produce three-dimensional patterns of chemical concentration gradients in vitro - with previously unattainable versatility and precision in both space and time.

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.
