Magnetic memory device is smallest demonstrated and uses record-low current. Memory-hungry, power-sapping big data might finally have met its match.

Electrical engineers at Northwestern University and the University of Messina in Italy have developed a new magnetic memory device that could potentially support the surge of data-centric computing, which requires ever-increasing power, storage and speed.

Based on antiferromagnetic (AFM) materials, the device is the smallest of its kind ever demonstrated and operates with record-low electrical current to write data.

“The rise of big data has enabled the emergence of artificial intelligence (AI)...

A nanoscale gold butterfly provides a more precise route for growing/synthesizing nanosized semiconductors that can be used in nano-lasers and other applications.

Hokkaido University researchers have devised a unique approach for making nanosized semiconductors on a metal surface. The details of the method were reported in the journal Nano Letters and could further research into the fabrication of nanosized light and energy emitters.

The approach, developed by Hokkaido University’s Research Institute for Electronic Science and Hokkai-Gakuen University, involves generating localized heat on a gold nanoparticle within a ...

New lithium metal anode could improve the longevity and energy density of future batteries. New research by engineers at MIT and elsewhere could lead to batteries that can pack more power per pound and last longer, based on the long-sought goal of using pure lithium metal as one of the battery’s two electrodes, the anode.

The new electrode concept comes from the laboratory of Ju Li, the Battelle Energy Alliance Professor of Nuclear Science and Engineering and professor of materials science and engineering...

Optical end-to-end solution includes encryption, transmission, decryption, and detection. BGN Technologies, the technology-transfer company of Ben-Gurion University of the Negev (BGU), Israel, is introducing the first all-optical “stealth” encryption technology that will be significantly more secure and private for highly sensitive cloud-computing and data center network transmission. The new all-optical encryption innovation will be introduced at the Cybertech Global Tel Aviv conference taking place January 28-30, 2020 in Tel Aviv, Israel.

“Today, information is still encrypted using digital techniques...
