Article Abstract

The electrochemical Na storage properties of hard carbon prepared by direct annealing of peat are limited by its open pore structure. Here, we report a co-annealing strategy that repairs the structure within the confined mesopore space in peat, achieving a capacity of 242.5 mAh g at a current density of 30 mA g with an initial coulombic efficiency of 74.71%.

Non-steroidal anti-inflammatory drugs (NSAIDs) residues pose a potential threat to aquatic ecosystems and food safety. In this work, novel imine bond/pyridine nitrogen-rich magnetic microporous organic networks (MMONs-Br and MMONs-I) were synthesized via a facile one-pot strategy using brominated and iodinated precursors for the detection of NSAIDs in fish. Brunauer-Emmett-Teller analysis revealed a striking 11-fold difference in specific surface areas between the two materials (MMONs-Br: 293.

Artificial cytoskeletons are constructed to study the structure and function of eukaryotic cells. Metal-organic frameworks (MOFs) provide a strong foundation for the construction of artificial cytoskeleton by encapsulating enzyme, yet challenges such as random enzyme distribution and poor catalytic efficiency, impede the development of artificial cytoskeleton technologies. Herein, a multilayer MOFs-based programmable artificial cytoskeleton was constructed through a heterogeneous interfacial growth method, utilizing hierarchical encapsulation of enzymes to facilitate tandem biocatalytic reactions.

Background: The separation of structural isomers is always a challenging task for liquid chromatography because of their similar physicochemical property. Research has found that materials with regular microporous structures exhibit excellent isomer separation performance. However, as the most easily available chromatographic material, silica stationary phases with regular and small mesopore structure have not yet been prepared, and it remains to be confirmed whether narrow pores in silica materials have the enhancing effect on shape selectivity in the separation of structural isomers.

Rational optimization of the pore size and topology of porous nanocarriers is crucial for improving the loading amount of luminophore and enhancing electrochemiluminescence (ECL) performance. In this study, an equimolar linear ligand replacement strategy was employed to synthesize novel mesoporous metal-organic frameworks (MOFs) for encapsulating Ru(bpy) (Ru@Zr MOFs) under room temperature without an acid modulator. Ingenious ligand substitution allows precise control of pore size, enabling encapsulation at the single-molecule level within mesoporous cages.

Background: Ultrasound-assisted transdermal drug delivery, or sonophoresis, enhances skin permeability, offering a non-invasive alternative for drug administration. However, its clinical application remains limited because of an insufficient understanding of its underlying mechanisms and optimal parameters. This study investigates the factors influencing ultrasound-enhanced drug absorption and examines its biological effects on skin structures and HaCaT cells, providing a comprehensive analysis of its mechanisms.
