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: 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: In this study, laser induced breakdown spectroscopy (LIBS) combined with multivariable analysis was used for the rapid identification of sea bass freshness without the use of organic solvents. The results showed that principal component analysis (PCA) accurately differentiated sea bass samples stored for different days and clustered different freshness grades together. The overall classification accuracy of partial least squares-discriminant analysis (PLS-DA) reached 91.50% +/- 1.49% and 97.33% +/- 1.90% for differentiating storage periods and freshness grades, respectively. This study demonstrated the capability of LIBS combined with chemometrics for the rapid and eco-friendly identification of marine fish freshness in the food supply chain.

Summary: In recent years, Laser-Induced Breakdown Spectroscopy (LIBS) has been recognized as a powerful technique for elemental imaging of samples. However, analyzing heterogeneous samples with multiple matrices poses new challenges. In this study, the behavior of plasma plumes at the boundary of two well-defined matrices was investigated using a combination of three-dimensional plasma imaging, spectroscopy, and Mach-Zehnder interferometry. The findings provide valuable insights into the factors that need to be considered when mapping fine heterogeneous structures using LIBS.

Summary: Laser-Induced Breakdown Spectroscopy (LIBS) has become an important technique for elemental imaging of samples, but analyzing heterogeneous samples with multiple matrices presents new challenges. This study investigated the behavior of plasma plumes generated on the boundary of two well-defined matrices using three-dimensional imaging, spectroscopy, and interferometry. The effects of collection optic angles and slight misalignment of the optics on the elemental distribution and signal intensities were analyzed. The findings provide valuable insights into the behavior of plasma plumes at the boundary of matrices and factors to consider when mapping fine heterogeneous structures using LIBS.

Summary: The laser-induced breakdown spectroscopy (LIBS) technique was used to investigate green fluorite samples. It was found that the emission bands of the CaF diatomic molecule in the fluorite samples exhibited stronger optical emission compared to the fluorine atomic lines. Chemical composition analysis using CF-LIBS was in good agreement with results from the EDX technique. The validity of the CF-LIBS results was confirmed using the calibration curve method, and a principal component analysis (PCA) technique was utilized to classify the fluorite samples.

Summary: The study investigated the reduction of self-absorption in the spectrum using double-pulse laser-induced breakdown spectroscopy, finding that the gas environment generated by the first laser beam affects the self-absorption effect of the plasma spectrum. It was observed that the spectral self-absorption effect is weakest at specific double-pulse delays for different elements, and that the double-pulse delay and the first laser beam energy have a strong correlation with the self-absorption effect.

Summary: Alzheimer's disease is a major cause of senile dementia and is characterized by the aggregation of neurofibrillary tangles and amyloid plaques in the brain. The A beta 1-42 peptide is considered the primary cause of neurotoxicity due to its insolubility and subsequent aggregation. A beta 1-42 and A beta 1-40 have been identified as relevant biomarkers for AD diagnosis, and SurfaceAssisted Laser Desorption/Ionization Mass Spectrometry (SALDI-MS) was used to monitor the A beta 1-42/A beta 1-40 ratio without prior sample treatment.

The biosensor combines the advantages of CRISPR/Cas13a and primer exchange reaction (PER) for target amplification. Under optimized conditions, the PER-E-CRISPR assay exhibits a linear range from 10-13 to 10-7 M and a limit of detection of 30.2 fM. The biosensor shows excellent performance in actual plasma, indicating promising prospects for miRNA detection in molecular diagnosis.

Summary: Molecular docking (MD) analysis is widely used for studying the interaction between aptamers and small molecules. This study established steady-state aptamers of tertiary structures (SATS) using specific aptamers of tetracycline antibiotics as docking models. Molecular docking results revealed multiple binding sites in the SATS of aptamers, with significant variations in binding free energy (BFE) and docking score (DS). The study also proposed a method for MD analysis based on SATS, providing insights into binding mode and predicting binding sites.
