Asymmetric Active Center Triggers Side‐On Photo‐Fenton‐Like Reaction Through Polar Charge Transfer and Self‐Adapting Sulfur Vacancies

open access: yesAdvanced Science, EarlyView.
The Cu‐Zn3In2S6 photocatalyst (Cu‐ZISV) with asymmetric Cu‐SV‐Zn sites was designed and synthesized to boost peroxymonosulfate (PMS) activation kinetics. The side‐on photo‐Fenton‐like reaction by the asymmetric Cu‐SV‐Zn site accelerated PMS activation and pollutant degradation, and the first‐order kinetic constant of Cu‐ZISV increased by 4.87 times ...

A Bottom‐Up Design Framework for Multifunctional Lattice Metamaterials

open access: yesAdvanced Science, EarlyView.
This study introduces a generative AI framework for designing multifunctional lattice metamaterials. The method combines 3D Gaussian voxel generation with deep learning, enabling greater design freedom and structural performance. The optimized lattice metamaterials achieve enhanced energy absorption by 40–200% compared to conventional structures and ...

The Great Divide: Ruralisation of Poverty in Russia [PDF]

open access: yes, 2007
Using data from the RLMS for the period 2000-2004 we investigate poverty trends in Russia. We find that urban poverty declines at twice the rate of rural poverty so that by 2004 poverty in Russia had become a largely rural phenomenon for the first time ...

Synergistic Enhancement of Catalytic Activities in Ligand‐Regulated Carbon Dots‐Ferric Ion Nanozymes via UV‐Enhanced Peroxidase‐Oxidase

open access: yesAdvanced Science, EarlyView.
Three CDs‐Fe nanozymes functionalized with tailor‐made ligands (TPP, HEDP, and DTPA) are synthesized via hydrothermal carbonization and coordination chemistry. A ligand‐regulation strategy for CDs‐Fe nanozymes achieves tunable enzyme‐mimicking activities and a powerful synergistic effect between POD and UV‐induced OXD pathways, paving the way for ...

Thermal Cyclotrimerization Bridges Polymer‐Filler Interfaces for High‐Performance CO2 Separation Membranes

open access: yesAdvanced Science, EarlyView.
Thermal cyclotrimerization of nitriles converts interfacial discontinuity in MAF‐stu‐1/PIM‐1 MMMs into a continuity‐enhanced junction. Triazine–Zn2+ coordination between TR‐PIM chains and MAF‐stu‐1, together with hydrogen bonding and π–π stacking, lowers interfacial tension and builds selective CO2 pathways, enabling > 10 000 barrer CO2 permeability ...
