Power/Performance Bits: Aug. 20


Six-angstrom waveguide Engineers at the University of California San Diego, City University of New York, and Johns Hopkins University created the thinnest optical waveguide yet. At only three atoms thick, the team says the waveguide serves as a proof of concept for scaling down optical devices. The waveguide consists of a tungsten disulfide monolayer (made up of one layer of tungsten atoms ... » read more

Week in Review: IoT, Security, Auto


Internet of Things Paris-based Parrot Drones and five other companies were selected by the Pentagon’s Defense Innovation Unit and the U.S. Army to adapt off-the-shelf commercial drones for combat applications as part of the Army’s Short Range Reconnaissance program. SRR seeks to develop unmanned aerial vehicles that have a flight time of 30 minutes, a range of three kilometers (nearly two ... » read more

Power/Performance Bits: April 8


Predicting battery life Researchers at Stanford University, MIT, and Toyota Research Institute developed a machine learning model that can predict how long a lithium-ion battery can be expected to perform. The researchers' model was trained on a few hundred million data points of batteries charging and discharging. The dataset consists of 124 commercial lithium iron phosphate/graphite cells... » read more

The Week in Review: IoT


Investment Microsoft this week said it will spend $5 billion over four years on Internet of Things programs in research, development, and partner enablement. The company previously spent $1.5 billion on developing IoT technology. The move could pay dividends for the Microsoft Azure cloud platform and lead to wider use of Azure Stack, which pairs Microsoft software with hardware from approved p... » read more

Power/Performance Bits: April 3


Long-lived data storage Scientists from RMIT University and Wuhan Institute of Technology demonstrated a next-generation optical disk with up to 10TB capacity and a six-century lifespan using gold nanoparticles. The technology could radically improve the energy efficiency of data centers according to the researchers, using 1000 times less power than a hard disk center by requiring far less ... » read more

Switching a Perpendicular Ferromagnetic Layer by Competing Spin Currents


ABSTRACT "An ultimate goal of spintronics is to control magnetism via electrical means. One promising way is to utilize a current-induced spin-orbit torque (SOT) originating from the strong spin-orbit coupling in heavy metals and their interfaces to switch a single perpendicularly magnetized ferromagnetic layer at room temperature. However, experimental realization of SOT switching to date req... » read more

Manufacturing Bits: Dec. 13


Phonon lasers A European consortium recently kicked off a new project that will develop a practical phonon laser. The European consortium, called PHENOMEN, will be coordinated by the Catalan Institute of Nanoscience and Nanotechnology (ICN2). Most chips perform functions using an electrical charge (electrons) or by light (photons). In comparison, a phonon “is a quantum of energy or a q... » read more

Making Drones Secure


Critics have accused drones of creating multiple dangers, including invading privacy, colliding with other aircraft, threatening personal safety and even frightening livestock. Yet the biggest drone threat of all may turn out to be attacks made on the vehicles themselves. Drones, also known as UAVs (unmanned aerial vehicles) and UASs (unmanned aerial systems), need a variety of internal ... » read more

Week In Review: Manufacturing & Design


Don’t look now, but Intel is expanding its foundry business. Previously, Intel garnered a small collection of foundry customers. But Intel would not entertain foundry customers that had competitive products based on ARM chips. Apparently, Intel is having a change of heart. “I think they’ve changed their position,” said Nathan Brookwood, a research fellow at Insight 64. “They will do A... » read more
