Proceedings, annual meeting, Electron Microscopy Society of America, 1993
The environmental scanning electron microscope (ESEM) has evolved as the natural extension of the scanning electron microscope (SEM), both historically and technologically. ESEM allows the introduction of a gaseous environment in the specimen chamber, whereas SEM operates in vacuum.

Cracking in albumen photographs: An ESEM investigation
Microscopy Research and Technique, 1993AbstractThe preservation of nineteenth‐century albumen prints is of great concern to collection managers and to conservators of photographic materials. In the field of art conservation, preservation techniques incorporating aqueous treatments are often used to enhance the long‐ and short‐term stability of historical artifacts or art objects. In a study

Application of ESEM to fluxless soldering
Microscopy Research and Technique, 1993AbstractThe ESEM is ideally suited to study soldering processes. We have used it to observe solder reflow and joining in ambient gases. It reproduces effects of atmospheric pressure reflow in a hot stage light microscope, but with much better clarity and depth of field.

ESEM observation of thermal shock cracking
Microscopy Research and Technique, 1997We report a simple method for a quick and efficient localization of thermal shock cracks as narrow as 1 micron or less, using Environmental Scanning Electron Microscopy (ESEM). The non-destructive character of the technique is exploited in order to observe relevant fractographic features of the crack pattern.

Contrast and Resolution in the ESEM
Proceedings, annual meeting, Electron Microscopy Society of America, 1988The basic theory of contrast arid resolution for the SEM is applicable to the environmental scanning electron microscope (ESEM) except that it must be extended to include the effects of the gaseous environment on the beam-specimen—signals system. The resolution depends on the detection mode and the associated beam specimen interaction volume, provided ...

Observation of liquid transport in the ESEM
Proceedings, annual meeting, Electron Microscopy Society of America, 1986The environmental SEM (ESEM) allows the observation of liquid and liquid/solid systems in a controlled gaseous environment. In order to study the wetting properties of a wool fiber, or to understand various stages of wool scouring, a system has been devised which allows the transfer of microdroplets onto the specimen surface.

Electron Beam Profile in the ESEM
Proceedings, annual meeting, Electron Microscopy Society of America, 1988The examination of specimens in the presence of gas in the environmental scanning electron microscope (ESEM) requires the electron beam to pass through a minimum (optimum) 1ayer of gas before it strikes the specimen. The electron scattering by the gas molecules results in a modification of the original beam profile.

Cracking of Drying Latex Films: An ESEM Experiment
Langmuir, 2010In this study environmental scanning electron microscopy was used to observe the cracking of drying latex films below their glass-transition temperature. By controlling the relative humidity so that it decreases linearly with time, a critical level of humidity at which cracking occurs can be determined and this is measured as a function of film ...
