When we think of ions, we usually think of single atoms that have lost or gained some electrons, but entire molecules can also become ions. Physicists now show that cold molecular ions can be created ...

Positron, the antiparticle of electron, has the same mass and charge as that of an electron but with the sign flipped for the charge. It is an attractive particle for scientists because the use of ...

Researchers have achieved real-time capture of the ionization process and subsequent structural changes in gas-phase molecules through an enhanced mega-electronvolt ultrafast electron diffraction (MeV ...

Ions influence conductivity and mobility in molecular liquid crystals, affecting electrical behavior, stability, and performance in both established and emerging technologies. (Nanowerk Spotlight) The ...

For the experiment, an intense femtosecond ultraviolet laser pulse was employed to induce resonance-enhanced multiphoton ionization in 1,3-dibromopropane (1,3-DBP) molecules. The picosecond and ...
