Researchers at Nagoya University and RIKEN have developed a novel computational method to enhance the resolution of high-speed atomic force microscopy (HS-AFM) images for studying protein conformational transitions. The algorithm, normal mode flexible fitting-atomic force microscopy (NMFF-AFM), leverages normal-mode analysis to derive precise molecular models, potentially transforming the understanding of biomolecular dynamics.

To conclude this four-part series of spectroscopic instrumentation and components, we examine spectroscopy electronics, including printed circuit board (PCB) design and manufacturing, spectroscopy instrument design services, instrument testing services, and the firmware and software aspects of instrumentation.

A note from the editors of Spectroscopy regarding the "H-Classic Papers in Atomic Spectroscopy" article published in the November 2021 issue.

When performing literature searches, there are a number of essential points to remember to ensure that you gather the most relevant or essential papers.

Denise M. Mitrano is an Assistant Professor of Environmental Chemistry of Anthropogenic Materials at ETH Zurich in the Department of Environmental Systems Science. Her research is directed to understanding the impact and interaction of nanoparticles in the environment using atomic spectroscopy techniques, such as inductively coupled plasma–mass spectrometry (ICP-MS) and single-particle ICP-MS (sp-ICP-MS). She is the winner of the 2022 Emerging Leader in Atomic Spectroscopy Award. Chosen by an independent committee, the Emerging Leader in Atomic Spectroscopy Award recognizes the achievements and aspirations of a talented young atomic spectroscopist who has made strides early in his or her career toward the advancement of atomic spectroscopy techniques and applications. We recently interviewed Mitrano about her work.

As forensic analysis continues to advance, such as in the understanding of source identification and analysis of trace quantities of bodily fluids, spectroscopic techniques and machine learning are playing a significant role. Igor K. Lednev, a chemistry professor at the University at Albany, SUNY, in Albany, New York, has been working in this field with his team. The analytical methods currently under investigation include Raman spectroscopy, attenuated total reflection Fourier transform infrared (ATR FT-IR) spectroscopy, and advanced chemometric classification and analysis methods. We recently interviewed him about his work.

This issue is a compilation of five peer-reviewed articles on the combined application of UV-vis-NIR spectral data with advanced chemometrics.

L. Robert Baker, the 2021 Emerging Leader in Atomic Spectroscopy, applies ultra- fast, time-resolved X-ray spectroscopy to explore charge transfer at surfaces, to understand electron transfer, energy conversion, electrochemistry, and catalysis.

Dmitry Kurouski of the Department of Biochemistry and Biophysics at Texas A&M University in College Station, Texas, is applying Raman spectroscopy to important applications in agriculture for identification and classification of various plant species, for quantification of essential plant constituents, for disease diagnosis in plants, and for Raman-based digital and precision farming. He and his colleagues are at the forefront of using the advantages of Raman based measurements for non-invasive and non-destructive analyses for important field and remote measurement applications.

Although ICP-OES and ICP-MS are often considered mature techniques, probing the mechanisms involved can lead to more accurate results, and in some cases, cast doubt on accepted explanations. John Olesik shares some surprises he has encountered, in this first part of a two-part interview series.

Mun Seok Jeong of the Department of Energy Science at Sungkyunkwan University in Korea is exploring the nanoscale of material science using a suite of new spectroscopy tools. We recently spoke to him about his work.

We report on overall salary trends and how they compare to past years. We also look beyond the numbers to focus on broader trends of workplace satisfaction and career attitudes for spectroscopists.
