Dr Christoph Mätzig, who is moving within the AMETEK Group and has taken over the management of the Ultra Precision Technologies division, will be succeeded by Michael Privik.

In situ Raman and X-ray absorption spectroscopy can track the dynamic catalytic processes, capture the short-lived intermediates and reveal reactive sites.

A new X-ray technique developed at Cornell offers an unprecedented look at the elaborate inner workings of batteries while they are in use, and is already yielding important findings for the development of next-generation energy storage.

In a study that used inorganic, physical and analytical chemistry to mimic respiratory droplets that can carry viruses, researchers demonstrated a mechanism that enables multiple mask materials to be protective.

As a UvA professor, she will focus primarily on the application of molecular spectroscopy for the study of historic paints and their degradation.

The New York/New Jersey Section of the Society for Applied Spectroscopy are seeking nominations for their 2022 Gold Medal Award.
