Article Abstract
Ordered mesoporous silver nanoparticle/carbon composites have been produced by a "one-pot" synthesis method. They have open mesopores (4.2-5.0 nm), large specific surface areas (465-584 m(2) g(-1)) and high pore volumes (0.29-0.50 cm(3) g(-1)) and contain stable, confined but accessible Ag nanoparticles. As a result, they show high performance in catalytic reduction of 4-nitrophenol (4-NP). The mesostructure and particle size as a function of Ag content were studied and correlated with the catalytic activity. The ordered mesoporous carbon framework and highly dispersed Ag nanoparticles make the material a novel system for effective contacting with the reactants and catalysis of the reaction.

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.

Bent-core nematic liquid crystals exhibit unique properties, including giant flexoelectricity and polar electro-optic responses, making them ideal for energy conversion and electro-optic applications. When confined in nanopores, they can stabilize chiral nanostructures, enhance polar order, and enable defect-driven switching - offering potential in nanofluidics, sensing, and adaptive optics. The thermotropic ordering of the bent-core dimer CB7CB confined in anodic aluminum oxide (AAO) and silica membranes with precisely engineered cylindrical nanochannels - ranging from just a few nanometers to several hundred nanometers-is examined.

Here, we report a multifunctional hybrid membrane-coated nanomotor for cancer chemoimmunotherapy, which consists of mesoporous silica-coated iron oxide nanoparticles (MF) as a drug carrier, loaded with doxorubicin (DOX), l-arginine (l-arg), and glucose oxidase (GOx), and camouflaged with a hybrid of red blood cell membranes (mRBC) and cancer cell membranes (CCM). RM-GDL-MF has a cascade of catalytic reactions, where glucose is catalyzed by GOx to produce HO, and l-arg is oxidized by the produced HO to release nitric oxide (NO), leading to self-propelled motion in order to promote the penetration of the extracellular matrix (ECM) in the tumor. The hybrid membrane provides not only stealth properties from mRBC to evade immune clearance but also tumor-orientation ability to target the tumor from the CCM.

Because of their large surface area, electrical conductivity, and adjustable structure, mesoporous graphitic carbon-based materials show the most promise for electrochemical hydrogen storage (EHS). The electrochemical performance of these materials is further improved by integrating them with transition metal oxides.
