Summary: Geochemical imaging using handheld LIBS is a rapid and qualitative method to unravel the complex geological histories of rocks and minerals without the need for extensive sample preparation. This approach enables mapping of variably altered mantle xenolith samples with cm-scale geochemical images in the field, demonstrating the sensitivity for detecting low concentrations of light elements such as Li and Na.

Summary: The growing importance of fluoropolymers in high-tech applications and green technologies has led to an increased demand for their characterization. This study presents a novel approach for quantitative mapping of fluorine in fluoropolymer samples using laser-induced breakdown spectroscopy (LIBS). The approach is based on monitoring molecular emission bands arising from fluorine-containing molecules. The study evaluates two techniques - spray coating and sputter coating - for their effects on sensitivity and spatial resolution in elemental mapping.

Summary: Nanosecond-gated laser-induced breakdown spectroscopy (n-LIBS) was used to quantify fuel mole fraction in a high-speed combustor, showing unexpected results in low concentration fuel regions. An improved direct spectrum matching calibration matrix and comparison between different laser systems reduced measurement uncertainty and demonstrated insensitivity to specific lasers. Comparison between n-LIBS and numerical results provided good overall agreement, highlighting the importance of n-LIBS in diagnostic model testing.

Summary: Laser-induced breakdown spectroscopy (LIBS) is a useful technique for quantitative detection based on the properties of laser-induced plasma (LIP) at local thermodynamic equilibrium (LTE). The influence of ambient pressure on the spatial-temporal evolution of LTE for LIP is still not well understood, and the mechanism of this influence remains unclear.

Summary: The impact of altering laser focusing conditions on laser-induced breakdown spectroscopy experiments was investigated in both ambient Earth laboratory and simulated Martian atmospheres. Results showed that the peak emissions of ionic species occur when the laser plasma is initiated with a focused spot within the sample in ambient Earth laboratory air, while atomic emissions have peak intensities several millimeters deeper into the sample. In simulated Martian atmospheres, atomic emissions peak when the laser is focused within the sample, while ionic emissions have peak intensities near the surface of the sample.

Summary: In this study, laser-induced kohl plasma was generated near a transverse magnetic field of 0.8 T. The emission spectra analysis revealed that most of the emission line intensities decreased due to the field, with a few lines showing an increase. Plasma parameters such as electron temperature, electron number density, and plasma frequency were found to increase. The analysis of the kohl emission spectrum detected several elements, including lead and chromium, which may have chronic health effects.
