Materials scientists typically use solution-phase transmission electron microscopy (TEM) to reveal the unique physiochemical properties of three-dimensional (3-D) structures of nanocrystals. In a new report on Science Advances, ...
As any cook knows, some liquids mix well with each other, but others do not. For example, when a tablespoon of vinegar is poured into water, a brief stir suffices to thoroughly combine the two liquids. However, a tablespoon ...
