Advanced vibrational spectroscopic techniques such as Fourier transform infrared (FT-IR) and attenuated total reflection (ATR)-FT-IR spectroscopic imaging are important tools for understanding molecular interactions and using them to help engineer new products and processes. Sergei G. Kazarian, Professor of Physical Chemistry at the Department of Chemical Engineering at Imperial College London, UK, has used these advanced imaging techniques for applications as varied as studying crude oil fouling, analyzing pharmaceutical formulations in microfluidic channels, examining biological systems and biopsy samples, and investigating the pigment-oil interaction in priceless paintings at the microscale level. We recently spoke with him about this research.

In many areas of spectroscopy, scientists working at instrument companies often make valuable contributions, by advancing the practical application of techniques and by educating customers. Andrew Whitley of Horiba Scientific, is one such scientist. He works diligently to identify potential new areas for Raman applications, and also dedicates much of his time to educating spectroscopists and new users to the field about the benefits of using Raman spectroscopy. Here, Whitley discusses his continued interest in spectroscopy, his role educating others, and his hope for the future of Raman spectroscopy.

Although inductively coupled plasma-optical emission spectrometry (ICP-OES) and ICP-mass spectrometry (MS) are generally considered to be mature techniques, researchers continue to investigate the fundamentals of the techniques and improve their capabilities. Diane Beauchemin, a professor at Queens University in Kingston, Ontario, is engaged in that challenge. She recently spoke to Spectroscopy about methods she has developed for simultaneous speciation and her work to improve sample introduction efficiency, to improve sensitivity and detection limits.

In biology, the study of intracellular structures is important and requires analytical techniques with submicrometer resolution. Atomic force microscopy-infrared (AFM-IR) spectroscopy is one technique that has the required lateral spatial resolution to observe such structures. David Perez-Guaita, PhD, at the Centre for Biospectroscopy at Monash University in Australia, is pioneering work applying AFM-IR to the study of red blood cells infected with the malaria parasite.

Lasers are used for a wide range of industrial, medical, spectroscopic, and military applications. Daniel Kazal, a graduate research assistant in the Department of Chemistry and Biochemistry at the University of Maryland Baltimore County, has developed a novel technique for channeling sound using a tube-shaped laser beam that forms a thermal gradient. Based on his work with this approach, he received the 2017 FACSS Innovation Award. We recently spoke with him about this research. This interview is part of a series of interviews with the winners of awards presented at SciX.

Geochronology is an exciting area of atomic spectroscopy and earth science research. One of the goals is to answer tectonic questions, and in particular, how the crust responds to continent–continent collision. John M. Cottle, a professor of earth science at the University of California, Santa Barbara, is one of the scientists on that mission. Cottle and his research group are at the forefront of discovery in geochronology, combining both laboratory and field-based research. In particular, Cottle is a leader in the development of novel laser-ablation inductively coupled plasma–mass spectrometry (LA-ICP-MS) measurements and their application to tectonic questions in convergent orogens, which are mountain ranges formed when a continental plate crumples and is pushed upwards.

Near-infrared (NIR) spectroscopy is an important technique in the pharmaceutical industry because of its ability to provide information about bulk material without sample preparation. Multivariate calibration techniques are frequently used to analyze the NIR data. Robert Lodder, who is a professor in the Department of Pharmaceutical Sciences at the University of Kentucky in Lexington, Kentucky, uses NIR spectroscopy along with an interesting alternative calibration technique, molecular factor computing, in his work with an experimental drug for combating the Ebola virus. We recently spoke with him about his research.

The atomic spectroscopy techniques of laser-induced breakdown spectroscopy (LIBS) and X-ray fluorescence spectroscopy have different strengths. Lydia Breckenridge, a senior research investigator at Bristol-Myers Squibb, uses both techniques in her work in pharmaceutical development. Here, she shares some of the advantages and challenges of using these techniques, and how the greatest benefits are sometimes derived by focusing on their complementarity, and using them in combination.

Two-dimensional (2D) Raman correlation spectroscopy is a powerful analytical technique for analyzing a system under the influence of an external perturbation. Isao Noda, of the Department of Materials Science and Engineering, at the University of Delaware and Danimer Scientific, has been developing 2D Raman correlation spectroscopy and applying it to the study of various materials, including exciting new biopolymers. He recently spoke to us about this work.

In recent years, researchers have been making important developments to advance the effectiveness of spectroscopic techniques for biomedical uses ranging from the identification of infectious agents to measuring the edges of cancerous tumors. X-ray fluorescence (XRF) spectroscopy is among the techniques that can have useful medical applications. David R. Chettle, a professor in the Department of Physics and Astronomy at McMaster University in Hamilton, Ontario, Canada, uses XRF for the in vivo measurement of toxic elements in human subjects, with the goal of developing devices that can be used to investigate the possible health effects of toxin exposure. He recently spoke to us about his research.
