Experiments with bifluoride ions show evidence of hybrid bonds

Hydrogen bonds. (A) Types of hydrogen bonds depending on donor-acceptor distance. Potentials of proton motion are shown along with the first three quantum levels and the associated lowest-energy transitions. (B) Principal coordinates of any H-bond demonstrated with HF2−(aq): donor-acceptor distance (dFF), proton asymmetry (Δ), and linearity (δ). Credit: Science (2021).

Compressive fluctuations heat ions in space plasma

IMAGE: Artist’s impression of the ions and electrons in various space plasmas. view more  Credit: Yohei Kawazura New simulations carried out in part on the ATERUI II supercomputer in Japan have found that the reason ions exist at higher temperatures than electrons in space plasma is because they are better able to absorb energy from compressive […]

Surrey helps to produce the world’s first neutron-rich, radioactive tantalum ions

An international team of scientists have unveiled the world’s first production of a purified beam of neutron-rich, radioactive tantalum ions. This development could now allow for lab-based experiments on exploding stars helping scientists to answer long-held questions such as “where does gold come from?” In a paper published in Physical Review Letters, the University of […]
