SEM stands for scanning electron microscope. The SEM is a microscope that uses electrons instead of light to form an image. Since their development in the early 1950's, scanning electron microscopes ...

New research from Washington University in St. Louis explains the cellular processes that allow a sun-loving microbe to “eat” electricity — transferring electrons to fix carbon dioxide to fuel its ...

The method points to easier on-chip control for next-generation submicron devices. (Nanowerk News) Rice University researchers used a focused electron beam to pattern device functions with submicron ...

For the first time, scientists visualized how electrons behave during a chemical reaction, which could help reduce unwanted byproducts in future chemistry. When you purchase through links on our site, ...

Excitons are pairs of bound negatively charged electrons and positively charged holes that form in semiconductors, enabling ...

According to [Asianometry], no one believed in the scanning electron microscope. No one, that is, except [Charles Oatley].The video below tells the whole story. The Cambridge graduate built radios ...

Physicists have studied a rare molecule to look at how magnetism is distributed within a radioactive nucleus for the first time. The rules of nature don’t, generally speaking, change. If you toss a ...
