Nanotechnologists could have a firmer handle on the forces at play in their microscopic world thanks to recent physics research at Purdue University.
The latest in a series of experiments aimed at revealing fundamental knowledge of the universe has yielded precise measurement of the so-called Casimir force – a force that could make tiny machines behave erratically, causing a thorn in the side of nanotechnology manufacturers. A team, including Purdue physicist Ephraim Fischbach, has answered sciences questions about the Casimir forces effects, which could help manufacturers work around the problem.
"The Casimir force is not a new discovery, but its effects on machines are essentially negligible until you start building at the nanoscale," said Fischbach, a professor in Purdues School of Science. "Now that nanotechnology is pervading industry, it will be important for us to understand how this force can hinder – or help – in our efforts to build the worlds tiniest machines."

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
