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.

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.

The Performance of ESEM and BSEM in Structural Equation Models with Ordinal Indicators

, 2020
Recent developments allow for incorporating exploratory features into structural equation models (SEM). Two approaches, exploratory SEM (ESEM) and Bayesian SEM (BSEM), have been shown flexible of estimating complex SEM. This simulation study compared the

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 ...

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

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.

Microstructures of bitumen observed by environmental scanning electron microscopy (ESEM) and chemical analysis using time-of-flight secondary ion mass spectrometry (TOF-SIMS)

Fuel, 2018
The aim of this study is to characterize structures induced on bitumen surfaces under analysis by environmental scanning electron microscopy (ESEM), and to examine possible contributing factors to the formation of their formation. Various bitumen samples
