Summary: Electrochemical sensors have wide-ranging applications in environmental, industrial, and chemical analysis. This review provides an overview of two types of sensors: electrocatalytic sensors, which involve oxidation and reduction reactions through electron transfer, and photoelectrocatalytic sensors, which involve a current response due to light incidence and redox reactions. The review also discusses how the detection capacity and behavior of these sensors can be influenced by various factors related to the electrode material. Inorganic, organic, and hybrid materials are compared for their use in electrocatalytic and photoelectrocatalytic sensors.

Summary: The incorporation of BN units into organic scaffolds by isoelectronic/isosteric substitution has proven effective in producing new materials. However, the knowledge about BN-doped inorganic-organic hybrid polymers is limited, especially for linear or cyclolinear macromolecules with longer inorganic chains. In this study, 1,2,5-azadiborolane was introduced as a novel building block for polymers. By coupling it with a p-phenylene diamine-based co-monomer, a hybrid polymer with a B2N3 chain and a considerable molecular weight was obtained. The UV-vis spectra revealed a red-shift in the longest-wavelength absorption band with increasing number of BN units in the chain.

Summary: The modern lifestyle and increased industrialization pose a threat to living organisms due to pollutants released from industries and household waste. Wastewater treatment is urgently needed to remove organic and inorganic pollutants. This review focuses on the use of bismuth-based materials for the removal of pollutants, as they have low toxicity and excellent properties compared to other metals. Photocatalytic degradation of organic pollutants using bismuth-based materials is discussed in detail, and the research on the removal and sensing of heavy metals using bismuth-based materials is summarized.

Summary: The co-deposition of DEBBA and Se atoms on the Ag(111) surface resulted in the formation of an adjustable organic-inorganic hybrid self-assembly system, leading to the evolution of various chiral molecular networks dependent on the coverage of Se atoms. The atom-coverage dependent evolution demonstrated the significant structural adaptability of Se clusters as building blocks for achieving maximum non-covalent interactions, allowing for flexible control and potential applications.

Summary: The synthesis and characterization of the first mesogenic donor-acceptor polyoxometalate (POM)-based hybrid were described. In the solid state, the compound exhibited birefringent behavior with lamellar organization, and the fluorescence of the organic donor unit was significantly quenched, attributed to the occurrence of an intramolecular charge-separated state.

Summary: This study focuses on benchmarking and improving molecular mechanics models for organic friction modifier additives used in lubricants. The generalized amber force field is found suitable for modeling oil-steel interfaces, with explicit refinements implemented for interactions with fatty acid glycerol esters on steel surfaces. The research also introduces a systematic scheme for elucidating the association of additive films to oil-hematite interfaces from molecular dynamics simulations, proposing 'saturated' interface models of densely packed OFMs.

Summary: Mas gene-related G protein-coupled receptors (MRGPRs) play a fundamental role in pain and itch sensation, with MRGPRX2 and its murine orthologue MRGPRB2 mediating pseudoallergic drug reactions. The study identified a class of commonly used drugs that activate MRGPRX2, primarily consisting of cationic amphiphilic drugs, leading to degranulation of mast cells and scratching behavior in both human and mice models. This research contributes to understanding the structure-activity relationships and functionality of MRGPRX2 ligands to predict and prevent adverse reactions such as drug-induced pruritus.

Summary: Classical nucleation theory is the most commonly used theory in describing nucleation processes, but recent studies have revealed nonclassical features in the early stage of nucleation. The fluid-to-solid transition leads to the so-called two-step nucleation mechanism, involving the existence of a metastable intermediate phase alongside the initial supersaturated solution and the final crystals.

Summary: The study found that the nature of substituents attached to the polycyclic backbone determines the long-range order, crystallinity, and layer thickness of the 2D-extended films. Compounds with a carbonyl unit at the bridge position serve as a superior building block compared to thioketone-bridged derivatives due to their flat core unit. Furthermore, the nature and length of peripheral substituents impact the orientation of the aromatic core unit within highly crystalline films.

Summary: Experimental evidence indicates the formation of dense liquid regions in NaCl bulk solution at unprecedentedly high levels of supersaturation, providing new insights into the detailed mechanism of two-step nucleation for many other aqueous solutions. The evolution of solute clusters and breakage of hydration in highly supersaturated conditions were observed, leading to a better understanding of the early stages of nucleation.
