Resolving Diagonal Peaks in Two-Dimensional and Transient Absorption Spectroscopy Using a New Polarization Scheme

June 07, 2022

Professor Martin Zanni, the Meloche-Bascom Professor of Chemistry at the University of Wisconsin-Madison, and his colleagues explored how to resolve diagonal peaks using a polarization scheme that can be implemented in pump-probe beam geometry—not only in two-dimensional infrared (2D-IR) spectroscopy but also in TA spectroscopy. Zanni is the 2022 recipient of the Ellis R. Lippincott Award. This interview is part of an ongoing series of interviews with the winners of awards that are presented at the annual SciX conference, which will be held this year from October 2 through October 7, in the Greater Cincinnati/Northern Kentucky area.

Using Back-Reflection-Enhanced Laser-Induced Breakdown Spectroscopy (BRELIBS) for the Elemental Analysis of Transparent Materials

March 08, 2022

Mohamed Abdel-Harith of Cairo University and his team explored using BRELIBS for the elemental analysis of the synagogue’s glass shards. Their findings reveal the potential of BRELIBS in conducting elemental analysis on transparent materials. Spectroscopy recently spoke to Abdel-Harith about this work.

Using Laser-Induced Breakdown Spectroscopy (LIBS) for Protein-Based Analysis and the Identification of Meat Species

March 02, 2022

Meat fraud has emerged as a growing concern globally. The adulteration, substitution, or mislabeling of meat products has resulted in negative economic effects, such as unfair competition in the global marketplace, as well as ethical concerns, because consumers want to know what is in the meat they are consuming. Ismail H. Boyaci of Hacettepe University and his team have explored using laser-induced breakdown spectroscopy (LIBS) for protein-based analysis and the identification of meat species. Spectroscopy recently spoke to Boyaci about this work.

Investigating Protein Receptors and Other Biomolecules Using SERS and TERS

September 02, 2021

Zac Schultz of The Ohio State University and his team used tip-enhanced Raman spectroscopy (TERS) and surface-enhanced Raman spectroscopy (SERS) with gold nanostars to investigate chemical reactions involved in protein–ligand binding. He recently spoke with Spectroscopy about his findings.

High-Definition Fourier Transform Infrared Spectroscopic Imaging of the Tumor Microenvironment

September 02, 2021

Professor Rohit Bhargava and his team at the University of Illinois, where they have established the Cancer Center at Illinois, are advancing research in tumor microenvironments, using techniques such as high-definition Fourier transform infrared (HD-FT-IR) coupled with machine learning. We recently spoke to Bhargava about this work.
