ZnO varistor ceramics were synthesised by cold sintering/spark plasma sintering and post-annealing treatment. Intriguingly, the ZnO varistor ceramics present ultrahigh potential gradient, high ...

Why is understanding high-voltage oil-filled transformer bushings so critical? High-voltage power transformers are an essential component of our nation's electric grid infrastructure. Bushings are the ...

The as-synthesized quinary full-concentration-gradient cathode g-NCMAB features a Mn-rich Ni-poor surface and radially aligned primary particles, effectively enhancing surface chemical stability, ...
