The Infrared and Raman Discussion Group’s 238th meeting on December 21 will feature the IRDG-Coblentz Lecture, two award presentations, and talks spanning clinical Raman, SERS, and ultrafast spectroscopy.

Organized by CPACT, the April 27 to 29 meeting at the Marriott Pittsburgh City Center will bring together scientists, engineers, and vendors across the process industries, with keynotes on PAT, Raman, and NIR applications and an abstract deadline of December 7, 2026.

Garth Simpson of Purdue University outlines plans to survey more ordered molecular assemblies and to apply interface-specific chiral spectroscopy to enzyme reactors, solid-phase synthesis, spin-selective reactions, and, ultimately, a new analytical method.

In this Eastern Analytical Symposium (EAS) interview, Garth Simpson of Purdue University explains how a simple geometric effect at interfaces produced a 4.5-degree rotation in fluorescence emission from a naproxen monolayer.

A Q&A interview from SciX explored a porous-particle Raman platform became an alternative to SERS, and why AI could unlock biochemical meaning in vibrational spectra.

Jürgen Popp, winner of this year’s Ellis R. Lippincott Award, discusses the regulatory, cost, and workflow hurdles of moving Raman spectroscopy into hospitals.

A recent conversation with Kevin Wilkinson, a professor of environmental chemistry at the Université de Montréal, sheds light on why no single signature can separate engineered nanoparticles from natural ones.

How do ions and water interact at the atomic level in nanochannels grafted with polymer brushes using all-atom molecular dynamics simulations? Siddhartha Das of the University of Maryland and his team are working on answering this question.
