Analyzing the Protein Secondary Structure in Tissue Specimens
May 19th 2025In the first part of this three-part interview, Ayanjeet Ghosh of the University of Alabama and Rohit Bhargava of the University of Illinois Urbana-Champaign discuss their interest in using discrete frequency infrared (IR) imaging to analyze protein secondary structures.
Exploring Data Transforms in Chemometrics
May 14th 2025Our “Chemometrics in Spectroscopy” column highlights the methodology that is used in order to apply chemometric methods to data. Integrating chemometrics with spectroscopy allows scientists to understand solutions to their problems when they encounter surprising results. Recently, columnists Howard Mark and Jerome Workman, Jr., wrote a series of articles about data transforms in chemometric calibrations. In this listicle, we profile all pieces in this series and invite you to learn more about applying chemometric models to continuous spectral data.
