In this interview segment from SciX, Juergen Popp explains why molecular “twins” built from optical measurements could reach patients within a decade, provided the field builds the regulatory, computing, and standards ecosystem around the technology.

Siddhartha Das explains how machine learning helps his group sift through roughly a trillion simulation data points. It reveals water and electroosmotic flow behavior and could speed the design of sensor-like channels.

In his SciX interview, Marc Porter discusses what happens to hydrogen when thiols bind to gold, how close analytical chemists can get to detecting a single molecule in a liter, and his new PFAS-focused startup.

From quarry fingerprints to bat-driven salt damage and hidden wall paintings, portable X-ray fluorescence, Raman spectroscopy, and isotope analysis are revealing how Angkor Wat was built and what threatens it today.

Yukihiro Ozaki of Kwansei Gakuin University received the Raman Lifetime Award at ICORS 2026 in Istanbul for outstanding lifetime contributions to Raman spectroscopy.

At SciX, Alessandro De Giacomo explained how airborne LIBS can produce quantitative results. Instead of relying on reference measurements, the method draws calibration directly from the measured signal, which sidesteps the drone’s positioning and motion problems.

At SciX, Jürgen Popp explains how miniaturized optical spectroscopy could add molecular data to wearable health tracking, which could enable earlier disease detection and a shift toward prevention.

At SciX, Jay Kitt describes the experiment he ran on his own that launched his cytochrome c research, and explains why putting a number on peptide–lipid interactions matters.

The following articles are the most accessed digital object identifier (DOI) manuscripts for Spectroscopy and LCGC International during the month of September 2026. Nine articles are individually ranked here by DOI page views; the third-highest entry (186 views) was recorded against the bare journal-level DOI rather than an individual article and is therefore not attributable to a single manuscript.

Near-infrared (NIR) spectroscopy, built on the weak overtone and combination-band absorptions first exploited commercially in the 1970s, is now being reshaped by chip-scale MEMS sensors, rapid field calibration methods, and increasingly capable chemometric and machine-learning models.

This Atomic Perspectives column explains how high-resolution continuum source graphite furnace molecular absorption spectrometry (HR-CS-GFMAS) quantifies extractable organic fluorine (EOF) as a PFAS sum parameter, complementing LC-MS/MS target analysis, with applications to German river sediments, bean plants, and fluorinated polymer sealing materials.

At SciX, Marc Porter explains how a Thanksgiving batting lesson led him to compare a bat meeting a ball to light scattering off a molecule, and how his group is using simulations to test whether the analogy holds.

Alessandro De Giacomo argues that grounding students in scientific fundamentals, rather than rushing them toward applications, is what makes breakthrough ideas possible.
