(Phys.org)—Americans consume 76 billion eggs per year, and while some of the eggshell waste is used for fertilizer or dietary supplements, the majority of these eggshells are thrown away. In a new study, researchers at ...
Usually, measuring the pH of a solution is not a problem. But how can researchers examine changes in acidity or alkalinity occurring at the nanoscale, for example, at a surface showing the very first signs of pitting corrosion? ...
