AI Article Synopsis
Article Abstract
The solid-state extraction technique and chromatography mass spectrometry were used to study the intrinsic composition of organic components of the mineral water obtained from the Munok deposit located in the Kazachinsko-Lensk district, Irkutsk region. The active components determining the mechanism of action of a mineral water-based preparation were identified and showed to operate similarly to those of Naftusya mineral water. The balneotherapeutic preparation was fabricated making use of the earlier developed technology of water vapor distillation. The analysis of organic components of mineral water and its extraction products showed the presence of aliphatic hydrocarbons with the high content of unsaturated compounds. The preparation thus obtained, unlike the standard balneotherapeutic medicines, does riot contain an inorganic matrix; it was shown to increase body resistance in the phase of remission in the patients treated for the management of urolithiasis.

Developing ambient ionization methods for direct mass spectrometry (MS) analysis is crucial for achieving sample-to-answer capabilities, especially for rapid analysis and monitoring in specific scenarios. Herein, a compact device is presented that utilizes mesh-collision microtube plasma (MC-μTP) ionization for direct online MS analysis. This device features a self-aspirating design that enables the direct analysis of various sample types.

The SiO electrode interface is passivated with a SiO layer, which hinders the deposition of an inorganic solid electrolyte interphase (SEI) due to its high surface work function and low exchange current density of electrolyte decomposition. Consequently, a thermally vulnerable, organic-based SEI formed on the SiO electrode, leading to poor cycling performance at elevated temperatures. To address this issue, the SEI formation process is thermoelectrochemically activated.

This study reports a green, multi-component synthesis of 2-aminoimidazole-linked quinoxaline Schiff bases using a novel superparamagnetic acid catalyst. The catalyst consists of sulfo-anthranilic acid (SAA) immobilized on MnCoFeO@alginate magnetic nanorods (MNRs), achieving high SAA loading (1.8 mmol g) and product yields (91-97%).

Carbon use efficiency (CUE) of microbial communities in soil quantifies the proportion of organic carbon (C) taken up by microorganisms that is allocated to growing microbial biomass as well as used for reparation of cell components. This C amount in microbial biomass is subsequently involved in microbial turnover, partly leading to microbial necromass formation, which can be further stabilized in soil. To unravel the underlying regulatory factors and spatial patterns of CUE on a large scale and across biomes (forests, grasslands, croplands), we evaluated 670 individual CUE data obtained by three commonly used approaches: (i) tracing of a substrate C by C (or C) incorporation into microbial biomass and respired CO (hereafter C-substrate), (ii) incorporation of O from water into DNA (O-water), and (iii) stoichiometric modelling based on the activities of enzymes responsible for C and nitrogen (N) cycles.

Rationale: Panax quinquefolius L. (PQ), a commonly used traditional Chinese medicine and a food, is usually processed into various products, including white PQ, red PQ (two- or three-time steamed PQ), and black PQ (nine-time steamed PQ). Previous studies demonstrated that volatile components (VOCs) were the important active substances of PQ, which had antibacterial, antiviral, and anti-leukemia activities.
