A recent review by researchers at Nagpur University and Seth Kesarimal Porwal College explores the ever advancing landscape of the Internet of Things (IoT) and its essential components—sensors and actuators. The review paper classifies various IoT sensors and examines their role in integrating the physical and digital worlds to enable smarter devices and enhanced automation.

Volker Deckert, the winner of the 2013 Charles Mann Award, is advancing the use of tip enhanced Raman spectroscopy (TERS) to push the lateral resolution of vibrational spectroscopy well below the Abbe limit, to achieve single-molecule sensitivity. Because the tip can be moved with sub-nanometer precision, structural information with unmatched spatial resolution can be achieved without the need of specific labels.

Spectroscopy recently sat down with Dr. Geraldine Monjardez and two of her coauthors, Dr. Christopher Zall and Dr. Jared Estevanes, to discuss their most recent study, which examined the crystal structure of ammonium nitrate (AN) following exposure to explosive events.

This article highlights key contributors who have significantly advanced the field of spectroscopy in recent decades.
