Spintronics Technology Revolution Could Be Just a Hopfion Away A decade ago, the discovery of quasiparticles called magnetic skyrmions provided important new clues into how microscopic spin textures will enable spintronics, a new class of electronics that use the orientation of an electron’s spin rather than its charge to encode data.  But although scientists have made big advances in this very young field, they still don’...

Light Unbound: Data Limits Could Vanish with New Optical Antennas Researchers at the University of California, Berkeley, have found a new way to harness properties of light waves that can radically increase the amount of data they carry. They demonstrated the emission of discrete twisting laser beams from antennas made up of concentric rings roughly equal to the diameter of a human hair, small enough to be placed on computer ch...

On-chip optical antennas remove data limits March 02, 2021 // By Jean-Pierre Joosting Latest research throws wide open the amount of data or information that can be simultaneously transmitted by a single light source. A new method of harnessing the properties of light waves that can radically increase the amount of data they carry has been discovered by researchers at the University of California, Berkeley. They demonstrated the emission of discrete twisting laser beam...

Researchers at the University of California, Berkeley, have found a new way to harness properties of light waves that can radically increase the amount of data they carry. The new work throws wide open the amount of information that can be multiplexed, or simultaneously transmitted, by a coherent light source.

A Sponge to Soak Up Carbon Dioxide in the Air A Q&A with Berkeley Lab scientist Jeffrey Long on a material for capturing CO2 February 22, 2021 405 Shares Berkeley Lab is pursuing a portfolio of negative emissions technologies and related research to remove carbon dioxide from the atmosphere. (Credit: Gary Whitton/Shutterstock) Human activity is now leading to the equivalent of 40 billion tons of carbon dioxide emitted into the atmosphere each year, putting us on track to increase the planet’s...

Researchers develop rechargeable, custom-fitting N95 masks Jeffrey Urban/Courtesy According to a press release from the Lawrence Berkeley National Laboratory, the new N95 mask model can be custom-fitted and 3D-printed. Additionally, the mask’s mesh filter, which is responsible for trapping virus particles, can be recharged, the press release states. Last Updated December 16, 2020 With personal protective equipment, or PPE, continuing to be in short supply due to the COVID-19 pandemic, researc...
