Research Bits: Sept. 9


All-silicon polarization multiplexer Researchers from the University of Adelaide and Osaka University propose an ultra-wideband integrated terahertz polarization (de)multiplexer implemented on a substrateless silicon base, which they tested in the sub-terahertz J-band (220-330 GHz) for 6G communications. “Our proposed polarization multiplexer will allow multiple data streams to be transmi... » read more

Quantum Batteries Constructed of a Microcavity Enclosing a Molecular Dye


Research paper titled "Superabsorption in an organic microcavity: Toward a quantum battery" from researchers at University of Adelaide (Australia), University of Sheffield (UK), Politecnico di Milano (Italy), University of St Andrews (UK), and Heriot-Watt University. Abstract (Partial) "Here, we implement experimentally a paradigmatic model of a quantum battery, constructed of a microcavity... » read more

What Quantum Batteries Have in Store


Quantum battery technology is approaching an inflection point similar to the one quantum computing crossed a decade or so ago, escalating it from a theoretical curiosity to an engineering challenge worth solving. Quantum batteries exploit the strange physical laws of the very small — the quantum world — to gain performance advantages over classical batteries. Recent research on charging ... » read more

Manufacturing Bits: Feb. 7


Design tools for solid-state batteries Oak Ridge National Laboratory has devised a new tool designed to accelerate the development of energy-dense solid-state batteries. The tool, called the Solid-State Battery Performance Analyzer and Calculator (SolidPAC), enables researchers to assess the impact of battery designs and choice of cell components for solid-state batteries. It can be used to... » read more

Power/Performance Bits: June 22


Terahertz silicon multiplexer Researchers from Osaka University and University of Adelaide designed a silicon multiplexer for terahertz-range communications in the 300-GHz band. “In order to control the great spectral bandwidth of terahertz waves, a multiplexer, which is used to split and join signals, is critical for dividing the information into manageable chunks that can be more easily... » read more

Power/Performance Bits: July 23


Image-recognizing glass Engineers at the University of Wisconsin-Madison, MIT, and Columbia University developed a way to create 'smart' glass capable of performing image recognition tasks without the need for electronics or power. "We're using optics to condense the normal setup of cameras, sensors and deep neural networks into a single piece of thin glass," said Zongfu Yu, electrical and ... » read more

Week In Review: Design, Low Power


Intel disclosed a speculative execution side-channel attack method called L1 Terminal Fault (L1TF). Leslie Culbertson, Intel's executive vice president and general manager of Product Assurance and Security, writes: "This method affects select microprocessor products supporting Intel Software Guard Extensions (Intel SGX) and was first reported to us by researchers at KU Leuven University, Techni... » read more

Power/Performance Bits: July 24


Single-atom storage Scientists at EPFL are working on a single-atom magnetic data storage device that takes advantage of quantum effects to provide dense storage. The team is using holmium, an element they've been exploring for years. "Single-atom magnets offer an interesting perspective because quantum mechanics may offer shortcuts across their stability barriers that we could exploit in t... » read more

Power/Performance Bits: Aug. 22


USB data leakage Researchers from the University of Adelaide found that USB connections are vulnerable to information leakage. In testing more than 50 different computers and external USB hubs, they found that over 90% of them leaked information to an external USB device. "USB-connected devices include keyboards, cardswipers and fingerprint readers which often send sensitive information to ... » read more
