Highly Efficient Air Sterilization via Low‐Temperature Interfacial Evaporation in Inductively Heated Superhydrophilic Ferromagnetic Filters

Advanced Science, Volume 12, Issue 44, November 27, 2025.
The first low‐temperature interfacial evaporation air sterilization technology is presented. It is based on a superhydrophilic ferromagnetic micro/nano‐structured stainless‐steel filter, showing ultra‐efficient inductive heating. This technology has demonstrated over 99.6% of SARS‐CoV‐2 and RSV elimination at temperatures in the 60–80 °C range.

High‐Isolation and Compact Wireless Power Supply for Gate Drivers of SiC Devices With Improved Class‐E Inverter

High Voltage, Volume 10, Issue 5, Page 1282-1292, October 2025.
ABSTRACT Gate drivers for high‐voltage silicon carbide (SiC) converters require a reliable power supply with strong isolation and compact size. However, existing gate driver power supplies (GDPS) with the transformer structure make it difficult to enhance the isolation performance while keeping the small coupling capacitance and volume.

Data‐Driven Temperature Deviation Estimation of a Proton Exchange Membrane Water Electrolyzer Stack from Electrochemical Impedance Using Machine Learning

IEEJ Transactions on Electrical and Electronic Engineering, Volume 20, Issue 9, Page 1488-1496, September 2025.
We developed a method to analyze temperature variations in proton exchange membrane water electrolysis stacks by using machine learning to interpret electrochemical impedance spectroscopy (EIS) data. To train the machine learning model, we artificially generated impedance data at various temperature differences by merging data from uniformly heated ...
