Although the detailed physics of what goes on inside a laser is typically complex, all conventional lasers share a common basic operational principle: a process known as the stimulated emission of ...
This article has been updated in January 2024. High resolution images of microscopic samples can be obtained experimentally using Scanning Electron Transmission Microscopy (STEM). It is an effective ...
The way electrons interact with photons of light is a key part of many modern technologies, from lasers to solar panels to LEDs. But the interaction is inherently a weak one because of a major ...
The way electrons interact with photons of light is a vital part of many modern technologies, from lasers to solar panels to LEDs. But the interaction is inherently weak because of a major mismatch in ...
Cryo-electron microscopy has exposed the structure of a bacterial virus with unprecedented detail. This is the first structure of a virus able to infect Staphylococcus epidermidis, and high-resolution ...
Science is one of the most fruitful sources of new terminology. There’s nothing like a surfeit of terms like “mitochondrial synthesis” and “quantum fluctuations” to make your writing sound ...
Researchers have found a way to create much stronger interactions between photons and electrons, in the process producing a hundredfold increase in the emission of light from a phenomenon called Smith ...
