This proposal requests funds to purchase a special scanning electron microscope that can examine wet, nonconducting or uncoated specimens without damage in the electron beam. The microscope can examine specimens during a dynamical process in an experiment. The researchers propose to use the instrument to study polymeric coatings and to observe the transport processes involved in wetting a solid surface. Other projects include the effect of seawater on composites, semiconductor surfaces used in electro- photochemistry, and hydration/dehydration reactions in clays.

该提案要求资金购买一种特殊的扫描电子显微镜，可以检查湿的、不导电的或未涂覆的样品，而不会在电子束中损坏。显微镜可以观察实验中动态过程中的标本。研究人员建议使用该仪器来研究聚合物涂层，并观察润湿固体表面所涉及的传输过程。其他项目包括海水对复合材料的影响，用于电光化学的半导体表面，以及粘土中的水合/脱水反应。
