The hydrolysis of hydrides, represented by MgH, delivers substantial capacity and presents an appealing prospect for an on-site hydrogen supply. However, the sluggish hydrolysis kinetics and low hydrogen yield of MgH caused by the formation of a passivation Mg(OH) layer hinder its practical application. Herein, we present a dual strategy encompassing microstructural design and compounding, leading to the successful synthesis of a core-shell-like nanostructured MgH@Mg(BH) composite, which demonstrates excellent hydrolysis performance. Specifically, the optimal composite with a low of 9.05 kJ mol releases 2027.7 mL g H in 60 min, and its hydrolysis rate escalates to 1356.7 mL g min H during the first minute at room temperature. The nanocoating Mg(BH) plays a key role in enhancing the hydrolysis kinetics through the release of heat and the formation of local concentration of Mg field after its hydrolysis. This work offers an innovative concept for the design of hydrolysis materials.

Aflatoxin B1 (AFB1) is one of the most toxic mycotoxins that pose great health threats to humans. Herein, an aptasensor-based fluorescent signal amplification strategy is developed for the detection of AFB1. Initially, the AFB1 aptamers labelled with carboxyfluorescein (FAM) are adsorbed onto graphene oxide (GO), triggering energy transfer.

Chlorinated hydrocarbons are widely used as solvents and synthetic intermediates, but their chemical persistence can cause hazardous environmental accumulation. Haloalkane dehalogenase from (DhlA) is a bacterial enzyme that naturally converts toxic chloroalkanes into less harmful alcohols. Using a multiscale approach based on the empirical valence bond method, we investigate the catalytic mechanism of 1,2-dichloroethane dehalogenation within DhlA and its mutants.

Transient electronics are emerging as a promising class of devices designed to disappear after a defined operational period, addressing growing concerns over sustainability and long-term biocompatibility. Built from biodegradable materials that undergo hydrolysis or enzymatic degradation, these systems are particularly well suited for temporary implantable applications, such as neural monitors, wireless stimulators, and drug delivery vehicles, as well as environmentally benign electronics for soil or aquatic disposal. Despite their potential, key challenges remain in expanding the material set for diverse functionalities, achieving high-density integration for advanced operations, and enabling precise lifetime control through strategies such as protective encapsulation.
