In-situ Detection of Rice Using Laser Induced Breakdown Spectroscopy and Machine Learning
March 20th 2025This research investigates the application of laser-induced breakdown spectroscopy (LIBS) and machine learning (ML) for detecting elemental composition of food, using rice as an example.
The Big Review V: The C-O Bond
March 20th 2025In the fifth installment of “The Big Review” of infrared (IR) spectral interpretation, we review the spectroscopy of functional groups containing C-O bonds, discuss alcohols and phenols, and see how to use IR spectroscopy to distinguish these alcohols from each other. We then discuss ethers and see how to use IR spectroscopy to distinguish the three different types from each other.
Tomas Hirschfeld: Prolific Research Chemist, Mentor, Inventor, and Futurist
March 19th 2025In this "Icons of Spectroscopy" column, executive editor Jerome Workman Jr. details how Tomas B. Hirschfeld has made many significant contributions to vibrational spectroscopy and has inspired and mentored many leading scientists of the past several decades.
Benefits of ICP-MS for the Elemental Compositional Analysis of Lithium-Ion Battery Electrolytes
March 19th 2025This month’s column investigates the elemental composition of electrolytes in lithium-ion batteries (LIBs) using inductively coupled plasma–mass spectrometry (ICP-MS).
