Going for Gold – PNNL Emerging Investigator Honored for IMMS Work

Published on: 6 Jul 2017, under FAIMS

Congratulations to Dr. Grant Johnson at Pacific Northwest National Laboratory on being invited to contribute his ion mobility – mass spectrometry (IMMS) work to the Royal Society of Chemistry’s pretigious emerging investigator issue of Chemical Communications. This annual issue highlights work by internationally recognized early career scientists who have made a big impact in their fields.

Johnson’s work with Dr. Marshall Ligare, Dr. Erin Baker, and Dr. Julia Laskin, PNNL, focuses on using IMMS to characterize the structural evolution of gold clusters encircled by ligands. The clusters have properties that could catalyze manufacturing reactions, producing more materials with less waste and using less energy. However, the role of the ligands in the synthesis, stability, and reactivity is unclear and remains a subject of debate between synthetic and theoretical chemists.

Johnson said: “Atom by atom, ligand by ligand, and charge by charge – we showed how the structure of the gold clusters evolved with ligand substitution,”. “This structural fluxionality is proposed to play a critical role in the enhanced catalytic properties of small clusters.” Read more about the special issue and Johnson’s research at PNNL here.
