Compact Scanning Electron Microscopes: Impressive Analytical Tools

Investigating Bacterial Pathogen-host Interaction by Using Scanning Electron Microscopes and Transmission Electron Microscopes

Electron microscopes have been widely used to investigate cell structures under high resolution. A scanning electron microscope (SEM) provides tridimensional images of a cell surface, while a transmission electron microscope (TEM) is commonly employed to observe the internal structure changes of host cells after bacterial adherence and invasion. The SEM and TEM can reveal bacterial location, bi...

A Physics-Based Imaging Model of Scanning Electron Microscopes

Handheld devices generally provide the facility of text input through keys that are an inconvenient and slow way of input. Digitizing tablets and light pens, on the other hand provide a natural and convenient way of input. There are many online character recognizers for languages based on Roman and Chinese characters but there is no such commercial product for Urdu/Arabic text input. We present...

Simulations and measurements in scanning electron microscopes at low electron energy.

The advent of new imaging technologies in Scanning Electron Microscopy (SEM) using low energy (0-2 keV) electrons has brought about new ways to study materials at the nanoscale. It also brings new challenges in terms of understanding electron transport at these energies. In addition, reduction in energy has brought new contrast mechanisms producing images that are sometimes difficult to interpr...

Characterization of a Miniature Electron Energy Analyzer for Scanning Electron Microscopes

Varieties of imaging with scanning probe microscopes.

T question comes up periodically at conference lunches where scanning probe microscopists are gathered: ‘‘Do you think we could image biological macromolecules under a thin layer of water?’’ It would be wonderful if we could confine biological macromolecules under a thin layer of water or other aqueous solution such that the biomolecules were all close enough to the surface for the atomic force...
