Application of ESEM to environmental colloids

Microscopy Research and Technique, 1993
AbstractEnvironmental colloids are toxic or radioactive particles suspended in ground or surface water. These hazardous particles can facilitate and accelerate the transport of toxicants and enhance the threat to humans by exposure to pathogenic substances.

Citation and Topic Analysis of the ESEM Papers

2015 ACM/IEEE International Symposium on Empirical Software Engineering and Measurement (ESEM), 2015
Context: The pool of papers published in ESEM. Objective: To utilize citation analysis and automated topic analysis to characterize the SE research literature over the years focusing on those papers published in ESEM. Method: We collected data from Scopus database consisting of 513 ESEM papers.

Introduction to the ESEM instrument

Microscopy Research and Technique, 1993
AbstractAn outline is presented of the first commercial environmental scanning electron microscope (ESEM). A concise description of this instrument and its operation, from a user's perspective, is given. More specifically, the description includes the electron optics, pressure stages and control, detection modes, resolution, and ancillary equipment ...

Universal ESEM

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.

Application of ESEM to fluxless soldering

Microscopy Research and Technique, 1993
AbstractThe 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.

Cracking in albumen photographs: An ESEM investigation

Microscopy Research and Technique, 1993
AbstractThe 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

ESEM observation of thermal shock cracking

Microscopy Research and Technique, 1997
We 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.

The application of ESEM in dental materials research

Journal of Dentistry, 1996
To describe the use of environmental scanning electron microscopy (ESEM) to investigate acid etching of enamel and to comment on future applications of ESEM in dental materials research.The acid etching of axially fractured specimens of human enamel by a 35% (ortho) phosphoric acid etchant was observed using ESEM.Most of the etching action, as evidence

Contrast and Resolution in the ESEM

Proceedings, annual meeting, Electron Microscopy Society of America, 1988
The 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, 1986
The 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.
