Fluorescence spectroscopy of gas-phase molecular ions combines mass spectrometric selection with optical excitation to probe the intrinsic electronic and structural properties of isolated ions. In a ...

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 ...

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 ...

Ion trap spectroscopy of molecular ions encompasses a suite of experimental techniques that confine charged molecules within radio-frequency or cryogenic multipole traps, cool them via buffer gas or ...

What if a surface could instantly switch from sticky to slippery at the push of a button? By using electricity to control how ions and water structure at the solid liquid interface of self-assembled ...

The interaction between solid matter and positron (the antiparticle of electron) has provided important insights across a variety of disciplines, including atomic physics, materials science, ...
