Non-Gaussian Analysis of Herbarium Specimen Damageto Optimize Specimen Collection Management
Knowledge Engineering and Data Science, 2022 Damage to specimen collections occurs in practically every herbarium across the world. Hence, some precautions must be taken, such as investigating the factors that cause specimen damage in their collections and evaluating their herbarium collection handling and usage policy.

An optimized TEM specimen preparation method of quantum nanostructures [PDF]
Micron, 2021 Electron transparent TEM lamella with unaltered microstructure and chemistry is the prerequisite for successful TEM explorations. Currently, TEM specimen preparation of quantum nanostructures, such as quantum dots (QDs), remains a challenge. In this work, we optimize the sample-preparation routine for achieving high-quality TEM specimens consisting of ...

STEM Imaging Optimized for Biological Specimen [PDF]
Microscopy and Microanalysis, 2005 Within STEM mode the signal of both the inelastic and elastic scattered electrons contribute to the contrast of the image. This is an advantage compared to zero-loss filtered TEM imaging, where a significant amount of electrons are not contributing to the image formation, especially in thicker samples, due to multiple scattering events.
