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.

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.
According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
