Nanoparticles form gradually after a semiconductor is dipped into a solution of metal salt. The cycle progresses from a surface of bare germanium (at the 12 oclock position) progressing clockwise to the same surface 500 minutes after immersion. The process occurs naturally, without the expensive equipment that is otherwise necessary to produce high-purity metals. (Graphic/Lon Porter)
Nanotechnology could make life easier for computer manufacturers and tougher for terrorists, reports a Purdue University research team.
A group led by Jillian Buriak has found a rapid and cost-effective method of forming tiny particles of high-purity metals on the surface of advanced semiconductor materials such as gallium arsenide. While the economic benefits alone of such a discovery would be good news to chip manufacturers, who face the problem of connecting increasingly tiny computer chips with macro-sized components, the group has taken their research a step further.
The scientists also have learned how to use these nanoparticles as a bridge to connect the chips with organic molecules. Biosensors based on this development could lead to advances in the war on terrorism.

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
