This paper discusses the use of hydrogen in various industries and energy sectors. It focuses on studying the properties and characteristics of hydrogen, which serves as a key factor in determining its potential in various applications. Such aspects of hydrogen application as environmental friendliness as well as utilization efficiency and safety are considered. The widespread use of hydrogen as a universal environmentally friendly energy carrier, raw material and fuel will successfully solve many significant ecological, energy and technological problems. The most important physical and chemical properties and thermodynamic characteristics of hydrogen described in the paper make it possible to choose among existing technologies or focus on developing new ones that will ensure high efficiency of its utilization not only at present but also in future. The information presented in the paper can be used for reference.

Bare silicon dimers on hydrogen-terminated Si(100) have two dangling bonds. These are atomically localized regions of high state density near to and within the bulk silicon band gap. We studied bare silicon dimers as monomeric units.

In this paper, a series of novel quinazoline-4(3)-one-2-carbothioamide derivatives (8a-p) were designed and synthesized the Wilgerodt-Kindler reaction between 2-methylquinazoline-4-one 10 and amines using S/DMSO as the oxidizing system. Their characteristics were confirmed by IR, NMR, HRMS spectra, and their melting point. These novel derivatives (8a-p) were evaluated for their anti-inflammatory activity by inhibiting NO production in lipopolysaccharide (LPS)-activated RAW 264.

The catalytic action of enzymes of a cascade trapped within a mesoporous electrode material is simultaneously energized, controlled and observed through the efficient, reversible electrochemical NAD(P)(H) recycling catalyzed by one of the enzymes. In their nanoconfined state, nicotinamide cofactors are tightly channeled current carriers, mediating multi-step reactions in either direction (oxidation or reduction) with a rapid response time. By incorporating a hydrogen‑borrowing enzyme pair, the internal action of which opposes the external voltage bias driving oxidation or reduction, a reduction process can be performed under overall oxidizing conditions, and vice versa.

This study proposed a hydrogel system using mung bean protein isolate (MPI) and carboxymethyl konjac glucomannan (CKGM). The effects of CKGM addition on the gel properties, structural characteristics, and Na loading capacity of the MPI-CKGM system were investigated. FTIR and molecular docking techniques demonstrated that MPI and CKGM formed hydrogels via hydrogen bonding interactions.

ConspectusIons are the crucial signaling components for living organisms. In cells, their transportation across pore-forming membrane proteins is vital for regulating physiological functions, such as generating ionic current signals in response to target molecule recognition. This ion transport is affected by confined interactions and local environments within the protein pore.
