Contactless manipulation method could be used in industries such as robotics and manufacturing,where devices wouldn’t need a built-in power source in order to move.

University of Minnesota Twin Cities researchers have discovered a new method to move objects using ultrasound waves. The study is published in Nature Communications, a peer-reviewed, open-access scientific journal.

Through the Quantum Looking Glass

Green laser light illuminates a metasurface that is a hundred times thinner than paper, that was fabricated at the Center for Integrated Nanotechnologies. CINT is jointly operated by Sandia and Los Alamos national laboratories for the Department of Energy Office of Science. (Photo by Craig Fritz) Click on the thumbnail for a high-resolution image.

A thin device triggers one of quantum mechanics’ strangest and most useful phenomena. An ultrathin invention could make future computing, sensing and encryption technologies remarkably smaller and more powerful by helping scientists control a strange but useful phenomenon of quantum mechanics, according to new research recently published in the journal Science.

Scientists at Sandia National Laboratories and the Max Planck Institute for the...
