High Voltage, Volume 10, Issue 1, Page 78-87, February 2025.Abstract Metal oxide varistors (MOVs) are extensively employed in DC circuit breakers (DCCBs) to suppress overvoltage, dissipate energy and build up voltage after interruption. Despite their widespread use, the performance of MOVs under short‐time, double energy absorption conditions is not well understood, posing a challenge to their application in ...

Precursor impurity‐mediated effect in the photocatalytic activity of precipitated zinc oxide
Journal of the American Ceramic Society, Volume 107, Issue 12, Page 8269-8280, December 2024.Abstract Photocatalytic degradation of pollutants using nanoparticles presents a promising method globally. However, effectively harnessing light absorption while mitigating recombination and nanoparticle agglomeration remains challenging. Here, we explore the synthesis and characterization of zinc oxide nanoparticles for photocatalytic dye removal in ...
