A Review of Failure Modes and Safety Strategies of Lithium‐Ion Batteries from Materials to Systems

Advanced Science, Volume 13, Issue 42, 28 July 2026.
A cascade‐aware framework is presented for lithium‐ion battery safety, linking thermal runaway initiation, acceleration, runaway reaction, and propagation with material‐, cell/pack‐, and system‐level interventions. By integrating failure mechanisms, quantitative safety indicators, and staged interception strategies, this review highlights how safer ...

Impact of QSW‐ZVS on Input EMI Filter Design in DC‐DC Converters

International Journal of Circuit Theory and Applications, Volume 54, Issue 7, Page 3545-3554, July 2026.
This paper analyzes the impact of quasi‐square wave zero voltage switching (QSW‐ZVS) on passive EMI filter design for DC‐DC buck converters. The extra element theorem (EET) is used to derive the design quantities that ensure converter performance is not altered, and the resulting damping element values are compared with those of traditional converters.

Design and Simulation of a Carrier PWM‐Based Capacitor to Support a Dynamic Voltage Restorer for Voltage Swell and Voltage Mitigation in the Distribution System

Engineering Reports, Volume 8, Issue 7, July 2026.
This study designs and simulates a capacitor‐supported dynamic voltage restorer (DVR) using Carrier PWM control to mitigate voltage sags, swells, and distortions in three‐phase distribution systems. The self‐supported DVR employs a DC‐link capacitor as an energy buffer, eliminating external storage needs. Control via Synchronous Reference Frame Theory (

Survival Remains High in Griffon Vultures 40 Years After Reintroduction

Animal Conservation, Volume 29, Issue 3, Page 307-320, June 2026.
The reintroduction of the Griffon vulture (Gyps fulvus) in French Grands Causses in 1981 is largely regarded as a significant translocation success. 40 years of quality data from intensive monitoring allows us to investigate the survival rates in this long‐lived population on the long term, but also to reflect on the crucial role of adaptive management
