AI Article Synopsis
- A new method using laser-induced plasma spectroscopy allows for clear analysis of deuterium, distinguishing it from hydrogen by a small wavelength difference.
- By optimizing conditions like surrounding gas and detection timings, researchers successfully resolved the emission lines for both elements.
- The technique shows promise for quantitative measurements of deuterium with a detection limit of 50 ppm and offers a quick approach for analyzing deuterium and hydrogen in solid samples.
Article Abstract
It was proved that the analysis of deuterium can be conducted using laser-induced plasma spectroscopy. By selecting the appropriate surrounding gas, its pressure, and gating time of the detection system, it was shown that the emission lines of both hydrogen (H(alpha)) and deuterium (D(alpha)), separated by only 0.179 nm, can be fully resolved. A linear calibration curve was also obtained, indicating that this technique has the potential for quantitative analysis of deuterium. The minimum detection limit achieved in this stage of research was estimated to be 50 ppm. We have also shown that this technique can be used as a simple and rapid method for D and H analysis in solid samples.

Ceramide (Cer) is synthesized in the endoplasmic reticulum (ER) using sphinganine as the common backbone and is then transported to the Golgi apparatus to synthesize two complex sphingolipids, sphingomyelin (SM) and glucosylceramide (GlcCer). Brefeldin A (BFA) affects the structure of the Golgi apparatus, resulting in the redistribution of the Golgi proteins into the ER. Therefore, BFA has been used to examine the ER-to-Golgi trafficking of lipids, but the detailed lipid changes in cells upon BFA treatment are not fully understood.

A Rh(III)-catalyzed sequential C-H bond addition to dienes and in situ formed aldimines was developed, allowing for the preparation of otherwise challenging to access amines with quaternary centers at the -position. A broad range of dienes were effective inputs and installed a variety of aryl and alkyl substituents at the quaternary carbon site. Aryl and alkyl sulfonamide and carbamate nitrogen substituents were incorporated by using different formaldimine precursors.

Neurodegeneration in Huntington's disease (HD) is accompanied by the aggregation of fragments of the mutant huntingtin protein, a biomarker of disease progression. A particular pathogenic role has been attributed to the aggregation-prone huntingtin exon 1 (HTTex1), generated by aberrant splicing or proteolysis, and containing the expanded polyglutamine (polyQ) segment. Unlike amyloid fibrils from Parkinson's and Alzheimer's diseases, the atomic-level structure of HTTex1 fibrils has remained unknown, limiting diagnostic and treatment efforts.

Ultraviolet (UV) hyperspectral imaging shows significant promise for the classification and quality assessment of raw cotton, a key material in the textile industry. This study evaluates the efficacy of UV hyperspectral imaging (225-408 nm) using two different light sources: xenon arc (XBO) and deuterium lamps, in comparison to NIR hyperspectral imaging. The aim is to determine which light source provides better differentiation between cotton types in UV hyperspectral imaging, as each interacts differently with the materials, potentially affecting imaging quality and classification accuracy.

One critical issue in hydrogen/deuterium exchange mass spectrometry (HDX MS) analysis is the deleterious back exchange. Herein, we report that when matrix-assisted laser desorption/ionization (MALDI) is used, the MALDI process itself can also cause significant back exchange. The back exchange occurred inside the reactive MALDI plume was investigated by depositing a fully deuterated sample prepared in DO on top of a preloaded dried layer of matrix.
