Applications of the environmental scanning electron microscope to the analysis of pharmaceutical formulations [PDF]
Scanning, 1996 AbstractElectron microscopy has been used for several years as a routine tool for the study of pharmaceutical formulations. However, it is usually desirable to obtain information on these systems in the wet state, and there are concerns regarding the interpretation of information provided by conventional electron microscopy where samples are subjected ...

Electron‐gas interactions in the environmental scanning electron microscopes gaseous detector [PDF]
Scanning, 1996 AbstractThe construction of high signal‐to‐noise, artefact‐free secondary electron images in the elevated pressure conditions of an environmental SEM is a nontrivial process. The interactions of information carrying species, as well as probe beam electrons, with the chamber gas are the major reasons for such complications. In this paper, we discuss and

Conditions for imaging emulsions in the environmental scanning electron microscope [PDF]
Scanning, 2002 AbstractEnvironmental scanning electron microscopy (ESEM) is a technique capable of imaging volatile and/or insulating samples in their natural state, without prior specimen preparation. It is thus a powerful potential tool for the study of the structure and dynamics of emulsions and other complex liquid systems, at a resolution greater than that ...

Cartilage Appearance Using an Environmental Scanning Electron Microscope [PDF]
Cell Preservation Technology, 2004 Because of technical principles, samples to be observed with electron microscopy need to be fixed in a chemical process and exposed to vacuum conditions that can produce some changes in the morphology of the specimen. The aim of this work was to obtain high-resolution images of the fresh articular cartilage surface with an environmental scanning ...
