Catalytic effects of multiple heterointerfaces on the hydrogen storage properties of magnesium hydride.

The application and further industrialization of magnesium hydride (MgH) are restricted by its intrinsically high de-hydrogenation temperature and dragged kinetics though it is believed as one of the most encouraging solid-state hydrogen storage materials with considerable capacity. Herein, a bimetallic layered MXene VNbC, which was mixed with MgH by high energy ball milling, was obtained by etching compact layered MAX VNbAlC with HF. The beginning de-hydrogenation temperature of the as-prepared MgH blended with 10 wt% VNbC (denoted as MgH-10 VNbC) composites was excitingly 170 °C and it exhibited faster kinetics and excellent cycling stability.

Carving Metal-Organic-Framework Glass Based Solid-State Electrolyte Via a Top-Down Strategy for Lithium-Metal Battery.

Traditional polymer solid electrolytes (PSEs) suffer from low Li conductivity, poor kinetics and safety concerns. Here, we present a novel porous MOF glass gelled polymer electrolyte (PMG-GPE) prepared via a top-down strategy, which features a unique three-dimensional interconnected graded-aperture structure for efficient ion transport. Comprehensive analyses, including time-of-flight secondary ion mass spectrometry (TOF-SIMS), Solid-state 7Li magic-angle-spinning nuclear magnetic resonance (MAS-NMR), Molecular Dynamics (MD) simulations, and electrochemical tests, quantify the pore structures, revealing their relationship with ion conductivity that increases and then decreases as macropore proportion rises.

A brief review on the progress of MXene-based catalysts for electro- and photochemical water splitting for hydrogen generation.

The development and generation of affordable and highly efficient energy, particularly hydrogen, are one of the best approaches to address the challenges posed by the depletion of non-renewable energy sources. Hydrogen energy, as a green and ecosystem-friendly source with zero carbon emission, can be generated through various methods, including water splitting (HER/OER) either photo- or electrocatalytic reactions. To implement these reactions effectively in practical applications, it is highly desirable to develop extremely efficient and cost-effective catalytic materials that are comparable to contemporary catalysts.

Self-limiting selective phase separation of graphene oxide and polymer composite solution.

Endoscopic ultrasound in the diagnosis of Ménétrier's disease: unique contribution.

Ménétrier's disease is a rare gastritis. Although there were some pathological features under gastroscopy, the depth of mucosal infiltration observed was not enough, and it was difficult to distinguish from other gastric mucosal lesions. A biopsy guided by gastroscopy is not deep enough and may lead to misdiagnosis due to incomplete sampling of the entire gastric mucosa.

Selective aggregation of natural ligands into efficient AIEgens on a human telomeric duplex-G-quadruplex junction.

DNA structures with the potential to concurrently recruit multiple ligands are promising in pharmaceutical and sensing applications when concentrated in a local environment. Herein, we found that human telomeric G-quadruplex (htG4) structures with a junction can selectively aggregate a natural ligand of tetrahydropalmatine (THP) into AIEgens. The htG4 monomer favors formation of a THP dimer emitting at ∼525 nm.
