A Novel Metal Foam‐Supported Solid Oxide Fuel Cell With High Specific Power

open access: yesAdvanced Science, EarlyView.
Solid oxide fuel cells (SOFCs) employing metal foam supports with an ultrahigh porosity of 90% and average pore size of 100 µm are successfully fabricated. The metal foam architecture significantly enhances gas diffusion coefficients, effectively reducing concentration polarization while simultaneously decreasing areal mass.

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 ...

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 ...

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

open access: yesAdvanced 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.

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 ...

Vacancy‐Suppressed Garnet Electrolytes for Durable Solid‐State Batteries

open access: yesAdvanced Science, EarlyView.
A Li/O‐rich sintering strategy effectively suppresses intrinsic lithium and oxygen vacancies in cubic garnet electrolytes, yielding a dense and stable microstructure. The vacancy‐controlled electrolyte exhibits enhanced interfacial and air stability, enabling long‐term solid‐state battery cycling and providing a general design principle for defect ...
