Diode Rectifier with Improved Quality Indicators for Electrical Energy

Power Electronics and Drives
Abstract In this work, we present a three-phase diode bridge rectifier with a power line current close to a sinusoidal shape. To benefit from this approach, a solution called ‘current modulation’ is used in the DC link of the rectifier.

Monitoring of electricity quality indicators using Wavelet transform

Yugra State University Bulletin
The paper presents a simulation model of an electric power supply system with a nonlinear load operating in a non-stationary mode. To analyze the non-sinusoidal mode, the use of a batch wavelet transform is proposed. The wavelet transform has a number of advantages, which can be used to implement electricity quality indicators into a monitoring system.

Entropy‐Driven Design of Low‐Melting‐Point Alloys via Compositionally Complex Strategy

Advanced Engineering Materials, EarlyView.
Conventional low‐melting‐point alloys (LMPAs) are limited by a narrow compositional space and inherent property trade‐offs. This review presents an entropy‐driven design strategy that overcomes these limitations, ushering in a new class of low‐melting‐point compositionally complex alloys (LMCCAs).

Enhancing Low‐Temperature Performance of Sodium‐Ion Batteries via Anion‐Solvent Interactions

Advanced Functional Materials, EarlyView.
DOL is introduced into electrolytes as a co‐solvent, increasing slat solubility, ion conductivity, and the de‐solvent process, and forming an anion‐rich solvent shell due to its high interaction with anion. With the above virtues, the batteries using this electrolyte exhibit excellent cycling stability at low temperatures. Abstract Sodium‐ion batteries

All‐in‐One Analog AI Hardware: On‐Chip Training and Inference with Conductive‐Metal‐Oxide/HfOx ReRAM Devices

Advanced Functional Materials, EarlyView.
An all‐in‐one analog AI accelerator is presented, enabling on‐chip training, weight retention, and long‐term inference acceleration. It leverages a BEOL‐integrated CMO/HfOx ReRAM array with low‐voltage operation (<1.5 V), multi‐bit capability over 32 states, low programming noise (10 nS), and near‐ideal weight transfer.
