Ionization mechanisms of captive atoms struck by light matter

Light interacting with hydrogen atoms enclosed in hollow cages composed of carbon atoms - referred to as fullerene material - produces ionisation. This phenomenon, which has been the subject of intense theoretical scrutiny, ...

Novel plasma jet offshoot phenomenon explains blue atmospheric jets

Ionised matter, like plasma, still holds secrets. Physicists working with plasma jets, made of a stream of ionised matter, have just discovered a new phenomenon. Indeed, Eduard Sosnin from the Institute of High Current Electronics, ...

Electron scavenging to mimic radiation damage

High energy radiation affects biological tissues, leading to short-term reactions. These generate, as a secondary product, electrons with low energy, referred to as LEEs, which are ultimately involved in radiation damage. ...

Better material insights with gentle e-beams

There are several ways to change a molecule, chemically or physically. One way is to heat it; another is to bombard it with light particles, or photons. A lesser known method relies on electron collision, or e-beam technology, ...

How repeated spot microdischarges damage microdevices

In microelectronics, devices made up of two electrodes separated by an insulating barrier are subject to multiple of microdischarges - referred to as microfilaments - at the same spot. These stem from residual excited atoms ...

Recipe for muon pair creation, in theory

A true-muonium only lives for two microseconds. These atoms are made up one positively and one negatively charged elementary particle, also known as muons. Although they have yet to be observed experimentally, a Japanese ...

Anti-hydrogen origin revealed by collision simulation

Antihydrogen is a particular kind of atom, made up of the antiparticle of an electron—a positron—and the antiparticle of a proton—an antiproton. Scientists hope that studying the formation of anti hydrogen will ultimately ...
