Penn State acousticians put their new prototype for a compact chiller, based on "green" technology that substitutes sound waves for environment-damaging chemical refrigerants, on first public display in conjunction with Earth Day in New York City.
The roll-out took place at a Ben & Jerrys scoop shop in New York City where the chiller was hooked up to a standard ice cream sales freezer cabinet and successfully kept the creamy merchandise in delicious condition. Ben & Jerrys partnered with Penn State, with financial and scientific support from its parent company, Unilever, to develop a more environmentally friendly prototype freezer cabinet.
Dr. Steven Garrett, the United Technologies Corporation professor of acoustics at Penn State who leads the thermoacoustic chiller research team, says, "We expect this new compact approach to thermoacoustic chillers to be used first in applications that are difficult for chemical refrigeration, such as beverage vending machines, cooling microprocessor chips in computers and, of course, ice cream sales cabinets.

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...
