A Bottom‐Up Design Framework for Multifunctional Lattice Metamaterials

Advanced 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 ...

Does Urban Polycentric Structure Improve Carbon Emission Efficiency? A Spatial Panel Data Analysis of 279 Cities in China from 2012 to 2020

ISPRS International Journal of Geo-Information
Urban spatial structure, shaped by human intervention in the natural environment, impacts the functional space and socioeconomic efficiency of cities. Against this backdrop, this study investigates the linkage between urban spatial structure (USS) and ...

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

Advanced 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 ...

MicrobeDiscover: A Knowledge Graph–Enabled AI Framework for Identifying Microbes for Inorganic Nanomaterial Biosynthesis

Advanced Science, EarlyView.
Microbial synthesis of nanomaterials (NMs) is eco‐friendly, but the screening of microorganisms is limited by inefficient traditional methods (currently only involving∽400 microorganisms/90 NMs). We propose AI framework MicrobeDiscover, integrating a knowledge graph of microbe‐NM interactions.

The power of creativity and the power of the city - the functioning of labour markets and its role for urban location in the restructuring of German advertising [PDF]

Urban socio-economic theory today strongly focuses on the role of labour markets in shaping the structure of the urban economy and society. Particularly the strong polarisation of the urban society is often explained through the polarised structure of ...

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

Advanced 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 ...

Metric and topo-geometric properties of urban street networks: some convergences, divergences and new results [PDF]

, 2009
The theory of cities, which has grown out of the use of space syntax techniques in urban studies, proposes a curious mathematical duality: that urban space is locally metric but globally topo-geometric.
