Soft Ionic and Electronic Triboelectric Nanogenerators: Toward Attachable and Implantable Biomedical Applications

open access: yesAdvanced Materials, EarlyView.
This review provides an overview of triboelectric nanogenerator (TENG)–based biomedical applications by classifying studies into electronic and ionic systems across attachable and implantable platforms. It summarizes key material choices, device structures, and working mechanisms that characterize current TENG‐based research, and outlines six future ...

LEAD: Literature Enhanced Ab Initio Discovery of Nitride Dusting Layers for Enhanced Tunnel Magnetoresistance and Lower Resistance Magnetic Tunnel Junctions

open access: yesAdvanced Materials, EarlyView.
Magnetic tunnel junctions (MTJs) using MgO tunnel barriers face challenges of high resistance‐area product and low tunnel magnetoresistance (TMR). To discover alternative materials, Literature Enhanced Ab initio Discovery (LEAD) is developed. The LEAD‐predicted materials are theoretically evaluated, showing that MTJs with dusting of ScN or TiN on ...

A Colloidal Quantum Dot Thermistor and Bolometer

open access: yesAdvanced Materials, EarlyView.
This work introduces colloidal quantum dot thermistors employing a potential barrier structure to tune the activation energy of transport and hence the temperature coefficient of resistance (TCR). Upon integration with plasmonic absorbers, the CQD‐based bolometer device enables room‐temperature wavelength‐selective photodetection across the mid‐ to ...

Power Grid Protection

Qatar Foundation Annual Research Conference Proceedings Volume 2014 Issue 1, 2014
Due to its inherent short-term dynamic, the power grid is a critical component of the energy system. When a dangerous event occurs in a section of the grid (i.e. a power line or a plant fails), the overall system is subject to the risk of a blackout.

People-powered grid

New Scientist, 2016
Rutkin features Transactive Grid's first version of a new kind of energy market. While solar panels on the roofs of terraced houses soak up the sun, a pair of computers connected to the panels quietly crunch numbers. First, they count how many electrons are being generated. Then, they write that number to a blockchain.

Capturing grid power

IEEE Power and Energy Magazine, 2009
Making electricity grids "smarter" and modernizing them so that they can accept large amounts of renewable energy resources are fairly universally accepted as steps necessary to achieve a clean and secure electric power industry. The best way to achieve this goal is a topic of debate among power system designers.
