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 ...

Grain Boundary Structure Ordering via Electroshock Treatment Enhances Strength‐Ductility Synergy

open access: yesAdvanced Science, EarlyView.
Electroshock treatment triggers atomic rearrangement, transforming disordered grain boundaries into ordered states without inducing recrystallization. This grain boundary ordering effectively relieves strain concentration and strengthens boundaries, enabling a simultaneous improvement in both strength and ductility.

High‐Pressure Modulation of Breathing Kagome Lattice: Cascade of Lifshitz Transitions and Evolution of the Electronic Structure

open access: yesAdvanced Science, EarlyView.
External pressure directly tunes the breathing distortion of the kagome lattice in Fe3Sn2, suppressing it near 15 GPa and reversing it at higher pressures. This structural modulation drives a cascade of Lifshitz transitions, reconstructs the Fermi surface, strengthens electronic correlations and carrier localization, and modifies ultrafast electron ...

A Drug‐Gated, Modular STAb‐T Immunotherapy With External Control

open access: yesAdvanced Science, EarlyView.
Engineered STAb‐TON cells act as programmable living factories that continuously secrete inactive antibody modules, which assemble extracellularly into a functional T cell engager only upon small‐molecule administration. This externally controlled platform enables reversible, on‐demand regulation of antitumor immunity, establishing a new paradigm for ...
