A cross-sectional transmission electron microscopy study of iron recovered from a laser-heated diamond anvil cell [PDF]

, 2008
This paper discusses the use of a focused ion beam for the preparation of cross-sectional transmission electron microscopy specimens from small samples, typically 150 micron in diameter, that have been recovered from a laser-heated diamond anvil cell. We

Highly Coherent Femtosecond Electron Pulses for Ultrafast Transmission Electron Microscopy [PDF]

EPJ Web of Conferences, 2019
We describe the implementation and detailed characterization of a laser-triggered field-emitter electron source integrated into a modified transmission electron microscope. Highly coherent electron pulses enable high resolution ultrafast electron imaging

Transmission Electron Microscopy Study of Graphite underin situIon Irradiation [PDF]

, 2012
Graphite is employed as a moderator and structural component in 18 of the UK's fleet of Magnox and Advanced Gas-cooled Reactors (AGRs). During the operational lifetime of a reactor, graphite undergoes complex physical and mechanical property changes ...

Scanning transmission electron microscopy* [PDF]

Journal of Microscopy, 1974
SUMMARYThe scanning transmission electron microscope is of quite recent origin, and it is only in the last few years that it has been shown that this instrument is capable of giving the same high resolution as the conventional electron microscope. In this article we examine the conditions necessary for the achievement of high resolution and also the ...

Multi-pass transmission electron microscopy

Scientific Reports, 2017
Feynman once asked physicists to build better electron microscopes to be able to watch biology at work. While electron microscopes can now provide atomic resolution, electron beam induced specimen damage precludes high resolution imaging of sensitive ...

Effect of processing parameters on microstructure of additively manufactured α+β titanium alloys [PDF]

MATEC Web of Conferences
The effect of processing parameters on the microstructure was investigated on three α+β alloys, namely Ti6Al4V (Ti64), Ti6Al2Sn4Zr6Mo (Ti6246) and Ti6.5Al3.5Mo1.5Zr0.3Si (TC11) fabricated by laser powder bed fusion (LPBF).
