Abstract
A Cambridge Mark II Stereoscan SEM equipped with TV scan capabilities has been modified to study both static and dynamic interactions of water with water sensitive materials. The design and operation of this instrument to permit it to be used at 10°C temperature and 6.5 mbar specimen chamber pressure are included.A study of the continuous interaction of water with a natural sponge is included to demonstrate the usefulness of the dynamic capability of this technology. A time‐lapse study of this hydration process shows how a sponge absorbs water. Micrographs of water freezing are also included. This instrument, which has a resolution of about 150 nm, can also be used for static studies of hydrated materials. We anticipate that this technology will be used to study many other dynamic and static liquid‐solid and liquid‐liquid interactions such as emulsions, detergency processes, crystallization, solubilization, and perhaps even living biological specimens.Keywords
