The Rice lab of chemist James Tour reported this week in the journal Science that sputtering zinc onto multilayered graphene enabled the team to remove a single layer at a time without disturbing the layers beneath.
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.
Borrowing a page from modern manufacturing, scientists from the Florida campus of The Scripps Research Institute have built a microscopic assembly line that mass produces synthetic cell-like compartments.
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.
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.
Infectious diseases researchers at Umea University in Sweden are studying the surface properties of bacteria together with materials scientists. Studies of the outermost parts of the cell walls of bacteria yield new information about the chemical composition of structures that are important for the capacity of bacteria to infect organisms.
After completing two collaborative training activities, both National Nanotechnology Center (NANOTEC) and Vocational Education Commission (VEC) decided to tie the knot by initiating a formal partnership agreement this afternoon at the Vocational Education Commission's office in Bangkok.
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.
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 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.
Nanotechnology exhibits great potential for the food industry. This broad and practically oriented course has therefore been put forward to meet the needs from industries to gain knowledge and understanding about current research going on in this expansive field. It deals with the current and coming applications of nanotechnology in the food industry.
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.
Kleinstroboter, die im Koerper praezise medizinische Eingriffe vornehmen: Ein vom Schweizerischen Nationalfonds (SNF) unterstuetztes Forscherteam entwickelt Prototypen, hat aber auch schon eine konkrete Anwendung am Start.
