Dual‐Function Electrocatalysis: Simultaneous Wastewater Remediation and Hydrogen Evolution—A Comprehensive Review

Carbon Energy, EarlyView.
Replacing the oxygen evolution reaction with the electro‐oxidation of pollutants and waste streams offers an energy‐efficient route for simultaneous hydrogen production and pollutant remediation. This review summarizes the reaction mechanisms, catalyst design principles, and emerging paired‐electrolysis strategies that govern activity, selectivity ...

Estimacija stanja u elektroenergetskom sistemu sa PMU uređajima i maliciozni napad injektiranjem loših merenja i njegova detekcija

Energija, Ekonomija, Ekologija
Ovaj rad istražuje značaj primene metode estimacije stanja u elektroenergetskim sistemima, posebno fokusirajući se na ulogu PMU (Phasor Measurement Unit) uređaja. Prikazane su osnovni principi i prednosti estimatora stanja u odsustvu PMU merenja, a zatim

A Comprehensive Review of Fault‐Current Limiter Technologies for Smart and Resilient Power Systems

Energy Science &Engineering, EarlyView.
This review compares superconducting, solid‐state, and hybrid fault‐current limiters (FCLs) for modern alternating current, direct current, and hybrid grids. It shows that optimal FCL selection depends on fault characteristics, network configuration, voltage level, protection coordination, and resilience requirements rather than on a universally ...

A Retinomorphic Graphene Transistor Implementing Direction‐ and Velocity‐Selective Computation for In‐Sensor Image Stabilization

Small, EarlyView.
A multi‐gated ion‐gel graphene transistor architecture emulates spatiotemporal dendritic filtering inspired by biological direction‐selective retinal circuits. Leveraging distributed resistance‐capacitive ionic relaxation delays under combined excitation‐inhibition pulse routines, the solid‐state device exhibits programmable direction‐selective index ...

Ultra‐Efficient Memristive Voltage‐Resistance Logic Framework With Integrated Readout Strategy Based on Hafnium Zirconium Oxide

Small Methods, EarlyView.
Spatiotemporal efficiency is a key concern in memristor‐based logic‐in‐memory architectures, where separate read operations to access resistance states fundamentally limit efficiency. This work demonstrates that logic outputs can be directly inferred from the intrinsic discharge dynamics of a two‐terminal memristive device.

Bad Data Detection Algorithm for PMU Based on Spectral Clustering

Journal of Modern Power Systems and Clean Energy, 2020
Phasor measurement units (PMUs) can provide real-time measurement data to construct the ubiquitous electric of the Internet of Things. However, due to complex factors on site, PMU data can be easily compromised by interference or synchronization jitter ...
