IN making some tests recently with an apparatus designed for the observation of large ions in the atmosphere, I have found evidence of a close connexion between the concentration of large ions and the ...

This report focuses on recent developments using bipolar electrochemistry as an effective tool for the fabrication of gradient polymer surfaces. The electrochemical doping and reactions of conducting ...

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 ...
