A Multifunctional Mesoporous Janus Separator With Optimized Mass Transport Regulation Enabling 800-Cycle Lithium-Oxygen Batteries. [PDF]

open access: yesAdv Sci (Weinh)
To resolve the fundamental cycling decay of lithium‐oxygen batteries arising from lithium dendrite propagation, anode corrosion, and cathode passivation, we fabricate a mesoporous silica/polyurethane Janus separator integrating interfacial protection and mass transport modulation, which markedly enhances battery cycling stability and cycle life ...

Ti‐Doping Activates Adjacent Zr Sites in Bimetallic MOFs for Cooperative Phospholipid Removals in Human Biomonitoring

open access: yesAdvanced Science, EarlyView.
Ti‐doped Zr/Ti bimetallic MOFs activate neighboring Zr sites to selectively capture phospholipids from serum through cooperative interactions. In nontargeted screening, the material minimizes matrix interference, expands detectable feature coverage, and enables broad recovery of diverse chemical hazards, providing a powerful cleanup strategy for LC ...

Rare‐Earth–Sulfur Surface Modification Enables SiC Ceramics for Low‐Frequency Electromagnetic Wave Absorption in Extreme Environments

open access: yesAdvanced Science, EarlyView.
By altering surface chemical bonds to prolong relaxation time and shift absorption to lower frequencies, SiC/rare earth–sulfur (RE─S, RE = La, Ce, Pr, Sm, Gd, Er) materials achieve excellent low‐frequency electromagnetic wave absorption under extreme conditions, offering a new direction for designing high‐performance SiC‐based absorbers.

Human‐Guided Bayesian Optimization Enables High‐Throughput Laser Annealing of Mesoporous SiOx Anodes for Lithium‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
An empirical‐aided active learning framework is developed to optimize high‐throughput laser‐induced photothermal annealing of silicon suboxide anodes. By integrating probabilistic machine learning with empirical domain knowledge, this approach achieves optimal electrochemical performance using limited experiments.

Mesoporous Catalytic‐Adsorptive Nanoregulator Orchestrates Biofilm eDNA/LPS Disassembly and TLR9/TLR4 Immune Reprogramming to Resolve Diabetic Foot Infections

open access: yesAdvanced Science
Chronic diabetic foot infections are severely hindered by tough biofilms and a self‐fueling hyperinflammatory microenvironment, primarily orchestrated by the synergistic interplay between extracellular DNA (eDNA) and lipopolysaccharides (LPS) which ...

Vanadium Cation Exchange‐Driven Reconstruction of MOF‐Derived Cobalt Hydroxide Electrodes for Electrocatalysis and Energy Storage

open access: yesAdvanced Science, EarlyView.
A room‐temperature vanadium cation exchange strategy is developed to achieve simultaneous structural reconstruction and electronic/defect modulation of ZIF‐67 on nickel foam. The resulting mesoporous V20–Co(OH)2 electrode exhibits superior OER activity with low overpotentials and enhanced lattice oxygen participation.

Preparation of Ru metal nanoparticles in mesoporous materials: influence of sulfur on the hydrogenating activity

open access: yes, 2003
Hydrogenating catalysts were prepared by inserting Ru into the pores of mesoporous Al-MCM-41 materials by selective adsorption of [Ru(NH3)(6)](3+). Ru/support catalysts were obtained after reduction with H-2.
