Transmission and scanning electron microscopy of cutis rhomboidalis
Anais Brasileiros de Dermatologia, 2021 Cutis rhomboidalis nuchae was assessed in a 65-year-old patient. Optical microscopy showed basophilic agglomerations in the reticular dermis with decreased elastic fibers.

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

Interlacing in atomic resolution scanning transmission electron microscopy [PDF]
, 2022 Fast frame-rates are desirable in scanning transmission electron microscopy for a number of reasons: controlling electron beam dose, capturing in-situ events or reducing the appearance of scan distortions. Whilst several strategies exist for increasing frame-rates, many impact image quality or require investment in advanced scan hardware.

A Deep Learning Approach to Identify Local Structures in Atomic‐Resolution Transmission Electron Microscopy Images [PDF]
Advanced Theory and Simulations, 2018 Recording atomic‐resolution transmission electron microscopy (TEM) images is becoming increasingly routine. A new bottleneck is then analyzing this information, which often involves time‐consuming manual structural identification.

Cross sectional evaluation of boron doping and defect distribution in homoepitaxial diamond layers [PDF]
, 2011 In some diamond-based semiconducting devices, large variations of doping level are required over short distances. Tools to determine doping level and defects distribution should therefore be developed.

Effect of processing parameters on microstructure of additively manufactured α+β titanium alloys [PDF]
MATEC Web of ConferencesThe 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).
