2D materials in electron microscope

Semiautomatic classification of cementitious materials using scanning electron microscope images

Segmentation and classification are prolific research topics in the image processing community, which have been more and more used in the context of analysis of cementitious materials, on images acquired with Scanning Electron Microscopes (SEM) . Indeed, there is a need to be able to detect and to quantify the materials present in a cement paste in order to follow the chemical reactions occurri...

the scanning electron microscope

it is only thirteen years since the scanning electron microscope has been available commercially. yet, even in this short period of time, this instrument has been a powerful tool in the investigation of topography, electrical and magnetic properties, crystal structure, cathodoluminescent characteristics etc. of solid specimens. today, this type of microscope has opened its place alongside the c...

Towards atomically precise manipulation of 2D nanostructures in the electron microscope

Despite decades of research, the ultimate goal of nanotechnology—top-down manipulation of individual atoms—has been directly achieved with only one technique: scanning probe microscopy. In this review, we demonstrate that scanning transmission electron microscopy (STEM) is emerging as an alternative method for the direct assembly of nanostructures, with possible applications in plasmonics, quan...

The electron microscope in palaeopathology.

INTRODUCTION Tim earliest palaeopathological studies were made in the eighteenth century and were concerned with the results of trauma and disease in fossil animals. In 1825 Granville made a careful macroscopic study of a Ptolemaic mummy and diagnosed ovarian dropsy: this was almost certainly an instance of cystadenocarcinoma of the ovary. Twenty-seven years later Johan Czermak, a distinguished...
