Learning Moisture‐Induced Damage From Vision: Diffusion Models for Real‐Time Monitoring of Additive Manufacturing Processes

open access: yesAdvanced Science, EarlyView.
We introduce a vision‐based real‐time monitoring system for additive manufacturing that detects subtle moisture‐induced degradation via a diffusion model‐based framework. The approach enables nondestructive assessment of moisture‐induced damage level and mechanical performance and establishes a practical route toward more intelligent, reliable, and ...

Halide Perovskite: A Rich Source of Thermal Insulator

open access: yesAdvanced Science, EarlyView.
Halide perovskites exhibit ultralow thermal conductivity driven by intrinsic lattice softness and strong anharmonicity, falling below conventional defect‐engineering limits. Weak metavalent bonding, A‐site rattling, and dynamic octahedral tilting drive phonon scattering to the Ioffe–Regel limit, where wave‐like tunneling replaces particle‐like ...

Promoting Electroreduction CO2 to Multi‐Carbon Products by Tailoring the *H Availability With Optimized Interfacial H2O Configuration

open access: yesAdvanced Science, EarlyView.
A catalysis system with adjustable interfacial H2O configuration was conducted by introducing ionomer into Cu. The increasing proportion of K+‐H2O can enhance the dissociation of H2O and improve the generation ability of *H, and the increasing proportion of 4‐HB‐H2O can accelerate the transfer speed of *H to *CO intermediates with the aid of strong ...

Solvent Oxidation‐Directed Synthesis of Highly Crystalline Iron Oxide Nanoparticles With Near‐Bulk Magnetization

open access: yesAdvanced Science, EarlyView.
Controlled oxidation of benzyl ether is established as a key synthetic parameter in the thermal decomposition of iron(III) acetylacetonate. Oxygenated solvent species alter precursor coordination and nucleation–growth kinetics, producing highly crystalline, magnetite‐rich nanoparticles with tunable size, controlled morphology, and near‐bulk ...

Facet‐Dependent Activity of Fe3S4 Crystal in Peroxydisulfate Activation for Organic Pollutants Degradation

open access: yesAdvanced Science, EarlyView.
Fe3S4 crystal with the exposed [001] facet exhibits higher catalytic activity for activating peroxydisulfate (PDS) to degrade clothianidin (CLO), which can be attributed to the dissolved Fe‐induced homogeneous catalytic process; while Fe3S4 crystal with the exposed [1‐21] facet exhibits excellent catalytic stability and durability, thereby boosting the
