Researchers at the European Space Research and Technology Centre (ESTEC) have developed a new framework for onboard hyperspectral image processing that uses deep learning to analyze massive volumes of spectral data in real time. Their review highlights lightweight neural networks, generative models, and hardware accelerators as key technologies shaping the next generation of spaceborne Earth observation.

An analytical method was established for determining the contents of 17 impurity elements in aluminum nitride by inductively coupled plasma optical emission spectrometry. The experiment investigated a dissolution method for samples, working conditions of the instrument, analytical spectral lines, matrix interference and correction methods, and detection limits.

Here are ten main unsolved problems in vibrational and atomic spectroscopy, each accompanied by a tutorial-style synopsis suitable for advanced practitioners or graduate-level students. Each of these tutorials, spanning advanced spectroscopy modeling, chemometrics, machine learning (ML) interpretability, and standardization, consists of a descriptive article. Each piece is well-referenced (with detailed matrix equations, radiative transfer models, chemometric derivations, and so forth), and includes the following. • Special focus on each topic—including mathematical derivations in matrix notation. • Conservative, verifiable content anchored to established reference sources. • Appropriate tutorial article structure: Title, Summary, Abstract, Introduction, Theory with equations, Examples, Discussion & Future Research, and References.

Spectroscopy spoke to Benjamin Manard, Senior R&D Staff Scientist and the Group Leader of the Chemical & Isotopic Mass Spectrometry Group at Oak Ridge National Laboratory (ORNL) as well as to Sarah Szakas and Jordan Stanberry, postdoctoral researchers at ORNL, regarding their work using examined single-particle inductively coupled plasma time-of-flight mass spectrometry (SP-ICP-TOF-MS) as a novel technique for uranium particle isotope ratio measurements.
