Transmission Electron Microscopy

2018
Conventional TEM (CTEM) is referring to the basic TEM techniques, i.e., electron diffraction and imaging techniques such as bright-field (BF), dark-field (DF) and high-resolution TEM (HRTEM). These techniques, in general, provide morphology and structural analysis of the specimen material. CTEM has been used to distinguish the analytical TEM tools that

Electron Transmission Microscopy of NiAl [PDF]

open access: possiblephysica status solidi (b), 1967
AbstractAn electron transmission study of the β‐phase of NiAl was made in annealed and deformed samples with the purpose of looking for antiphase boundary (APB), networks, and super‐dislocations and to observe other configurations of the deformed state.

Nanomeasurements in Transmission Electron Microscopy

Microscopy and Microanalysis, 2000
Abstract Nanomaterials have attracted a great deal of research interest recently. The small size of nanostructures constrains the applications of well-established testing and measurement techniques, thus new methods and approaches must be developed for ...

Cathodoluminescence in transmission electron microscopy

Journal of Microscopy, 2006
SummaryWe describe a cathodoluminescence spectrometer that is attached to an analytical transmission electron microscope. After a brief consideration of the set‐up and the peculiarities of recording spectra and of mapping defect distributions in panchromatic and monochromatic cathodoluminescence, we discuss two examples of applications.

Transmission Electron Microscopy of Endothelium

2022
Transmission electron microscopy using resin sections still remains an exceptionally useful tool in evaluating cellular ultrastucture within tissue. For the endothelium the best method for maintaining such structure is perfusion fixation: fixing the tissue under physiological pressure.

Transmission Electron Microscopy

1978
An electron microscope is an optical device for producing exceptionally high resolution of detail in the object by a beam of electrons.* There are three principal kinds of electron microscopes, classified according to how detail in the specimen is revealed by electrons: transmission, scanning, and emission.

ANALYTICAL TRANSMISSION ELECTRON MICROSCOPY

Annual Review of Materials Research, 2005
▪ Abstract  Chemical analysis at high spatial resolution is the domain of analytical transmission electron microscopy. Owing to rapid instrumental developments during the past decade, electron energy-loss spectroscopy offers now a spatial resolution close to 0.1 nm and an energy resolution close to 0.1 eV.

Transmission Electron Microscopy

2005
The distinguishing feature of transmission electron microscopy (TEM) is its ability to form images of atomic arrangements at localized regions within materials. It provides a view of the microstructure, that is, the variations in structure from one region to another, and the interfaces between them.

Transmission Electron Microscopy

1994
The ultimate resolution of any imaging technique is limited to about the wavelength of the radiation which carries the information. For light, the wavelength is on the order of 500 nm. However, modern science demands information from samples at far higher resolution—in the limit, it would be ideal to image individual atomic positions in crystals ...
