RECENTLY, with the increase of the resolving power of the electron microscope, it has become possible to make a direct observation of a crystal lattice composed of large molecules. J. W.

lattice parameters and crystal symmetry. It would be a real pity to turn down the extraordinary opportunities offered by abberation-corrected electron microscopy because of an unfortunately common ...

When all you’ve got is a hammer, everything looks like a nail. And when you’ve got a scanning electron microscope, everything must look like a sample that would be really, really interesting ...

In scanning electron microscopy, a thermionic electron source such as a tungsten filament is usually used. The subject of this tutorial, the Hitachi S-4700 FE-SEM, utilizes a cold cathode field ...

This unique formation of electrons is called the Wigner crystal (also called electron ice ... molecular crystal using scanning tunneling microscopy (STM) —- an imaging technique that produces ...

The FEI 200kV Titan Themis Scanning Transmission Electron Microscope (STEM) is a scanning transmission electron microscope with ... from a minimum area of 200 nm in diameter Convergent-beam Electron ...

There are hackers who have soldering setups on the dining room table, and then there are hackers who have scanning electron microscopes in their living room. [Macona] is part of the latter group ...

Two high-quality single-crystal sp²c-COFs have been developed, demonstrating the generality of this approach. This work addresses the bottleneck in synthesizing single-crystal COFs and provides ...

Look at these glucose crystals. But light microscopes have ... to places we'd never seen before - the electron microscope. The specimen is put in a vacuum and is viewed not by light waves but ...
