Identification of site-specific isotopic labels by vibrational spectroscopy in the electron microscope

Science, 2019
Mapping isotopically labeled alanine Electron microscopy of organic materials must avoid the destructive effects of electron beam impact. One approach is to measure vibrational spectra with electron energy-loss spectroscopy in a mode where the electron ...

The Electron Microscope

1975
The operation of the transmission electron microscope depends primarily upon the fact noted in chapter 2, that fast electrons are deflected by magnetic fields and can be focused by suitably constructed magnetic lenses. Thus in principle electrons can be used in the same way as light to form a magnified image of an object, but with the possibility that,

The future of the electron microscope*

Journal of the Royal Microscopical Society, 1967
SYNOPSISThe future of electron microscopy lies as much with the conventional as with the newer instruments. The point resolving power of the latter is likely to be pushed to 1 Å, but only after a considerable effort in solving problems of mechanical and electrical stability. Progress in correcting the lens aberrations is even slower.

Nanosecond electron microscopes

Ultramicroscopy, 2000
Combining electron optics, fast electronics and pulsed lasers, a transmission and a photoelectron emission microscope were built, which visualize events in thin films and on surfaces with a time resolution of several nanoseconds. The high-speed electron microscopy is capable to track fast laser-induced processes in metals below the ablation threshold ...
