Top articles published this week include interviews from our National Space Day content series, a news story about satellite-based spectroscopy, and an interview about battery analysis conducted at SLAC National Accelerator Laboratory.

Join us in celebrating National Space Day! Today, Spectroscopy magazine is teaming up with the Society for Applied Spectroscopy (SAS) to honor National Space Day and highlight the latest advancements in space exploration.

In honor of National Space Day, we interviewed Kelsey Williams, who is a postdoctoral researcher at Los Alamos National Laboratory (LANL) working on planetary instrumentation using spectroscopic techniques such as laser-induced breakdown spectroscopy (LIBS) and laser ablation molecular isotopic spectrometry (LAMIS). In Part I of our interview with Williams, she discusses how her background led her to her current position at LANL.

The Perseverance rover is equipped with many cameras and different instruments to conduct scientific experiments on Mars, including several spectrometers. We describe some of them here.

In a new study published in Measurement, researchers explored the power of low-frequency Raman spectroscopy for non-invasive drug analysis.

In Part 2 of our video interview with Johanna Weker of SLAC National Accelerator Laboratory, she discusses nutrient recovery systems and how X-ray techniques can improve them.

Researchers from Université de Tours have shown that serum mid-infrared spectroscopy (MIRS) may serve as a promising prognostic tool for identifying high-risk metastatic colorectal cancer patients undergoing first-line bevacizumab-based chemotherapy.

Researchers at Zhejiang University have developed an advanced optical modeling approach using spectroscopic ellipsometry, significantly enhancing the non-destructive analysis of amorphous silicon oxide thin films.

A recent study conducted by scientists in Brazil saw the development of a quick, non-invasive method to diagnose endometriosis.

"Inside the Laboratory" is a joint series with LCGC and Spectroscopy profiling analytical scientists and their research groups at universities worldwide. This series spotlights the current chromatographic and spectroscopic research their groups are conducting and the importance of their research in analytical chemistry and specific industries. In this edition of “Inside the Laboratory,” Johanna Nelson Weker of SLAC National Accelerator Laboratory discusses her laboratory’s work in battery analysis.

Researchers at Qiqihar Medical University have developed a dual-channel fluorescent probe, PYL-NBD, that enables highly sensitive, rapid, and selective detection of biothiols in food, pharmaceuticals, and living organisms.

A new tutorial provides a step-by-step, hands-on guide to using multivariate data analysis tools like PCA and PLS to extract meaningful insights from complex pharmaceutical data sets.

Top articles published this week include a preview of our upcoming content series for National Space Day, a news story about air quality monitoring, and an announcement from Metrohm about their new Midwest office.

Researchers from Tsinghua University and Qinghai University have uncovered how specific ambient gas properties affect the stability and accuracy of laser-induced breakdown spectroscopy (LIBS) signals.

Researchers from SGF International and Geisenheim University combine 1H NMR and HPLC-DAD to elevate juice quality assurance.

A new study published in Applied Food Research demonstrates that near-infrared spectroscopy (NIRS) can effectively detect subclinical bovine mastitis in milk, offering a fast, non-invasive method to guide targeted antibiotic treatment and support sustainable dairy practices.

Here is a collection of recent studies that used spectroscopic techniques in environmental analysis.

Jiangxi Agricultural University researchers use AI and vis-NIRS to predict meat quality and freezing duration with high accuracy.

Researchers from Jiangsu University and Zhejiang University of Water Resources and Electric Power have developed a transfer learning approach that significantly enhances the accuracy and adaptability of NIR spectroscopy models for detecting mycotoxins in cereals.

A recent study conducted by researchers from the Korea Institute of Fusion Energy and Jeonbuk National University presented a novel technique for analyzing lithium isotopes in liquid samples.

Top articles published this week include a tribute to John Albert Reffner, who was known for his work in infrared microspectroscopy, an application of Raman spectroscopy to improve recycling practices, and an Icons of Spectroscopy column on Karl Norris, known as the founder of near-infrared (NIR) spectroscopy.

In this brief segment from my full-length conversation with Monica Arienzo of the Desert Research Institute, she discusses the important key findings of her study.

In this brief segment from my full-length conversation with Monica Arienzo of the Desert Research Institute, she discusses the important key findings of her study.

In this brief segment from my full-length conversation with Monica Arienzo, who was the lead author of this study, she discusses whether there was a correlation between the different types of litter and the polymer type.

In this brief segment from my full-length conversation with Monica Arienzo, she explains why ATR FT-IR spectroscopy was the ideal technique of choice for her study characterizing polymers from the litter found on the lakebed of Lake Tahoe.

In the lead up to Earth Day 2025, we revisit an interview conducted with Monica Arienzo that discusses how ATR-FT-IR spectroscopy was used to classify polymers in plastic litter types found in Lake Tahoe back in 2023.
