Charge‐Transfer‐Mediated Boron Magneto‐Ionics: Towards Voltage‐Driven Multi‐Ion Transport

open access: yesAdvanced Science, EarlyView.
This study demonstrates voltage‐driven multi‐ion transport in FeBO systems, revealing simultaneous motion of B, Fe, and O ions enabled by charge‐transfer effects. By tuning oxidation states through oxygen incorporation, we achieve a transition from electrostatic‐like to electrochemical magneto‐ionic behavior. The findings establish boron magneto‐ionics,

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 ...

Coupled Fe3O4‐Cluster Precipitates and Single Fe‐Atom Catalysts Can Boost Oxygen Reduction via Concomitantly Accelerated Water Dissociation

open access: yesAngewandte Chemie, EarlyView.
Fe3O4 clusters can be precipitated onto Fe–N–C SACs through a residual‐oxygen‐assisted precipitation approach. Compelling evidence, including operando spectroscopy and ab initio calculations, suggests that Fe3O4‐cluster precipitates not only induce asymmetric electronic structures of Fe‐N4 active center to optimize the OH* adsorption, but also ...

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

Reductive Activation of White Phosphorus to [P4]2–, [P2]2–, and a Formal P2– Radical by Rare‐Earth Dinitrogen Complexes

open access: yesAngewandte Chemie, EarlyView.
Masked divalent yttrium and gadolinium dinitrogen complexes mediate the fragmentation of white phosphorus, converting P4 into discrete dimetallic complexes of [P4]2– and [P2]2– ligands, and an unprecedented monatomic P2– radical ligand. Structural, spectroscopic, magnetic, and DFT studies reveal insight into the bonding between these unusual Pn units ...

Atomically Modulating Competing Exchange Interactions in Centrosymmetric Skyrmion Hosts GdRu2X2 (X = Si and Ge)

open access: yesAdvanced Electronic Materials, EarlyView.
Our work bridges the gap between skyrmion discovery and material design by demonstrating how atomic‐scale control of exchange interactions enables tunable skyrmion phase transitions in centrosymmetric magnetic metals. ABSTRACT Magnetic skyrmions are topologically protected spin states that hold promise for shaping the future of electronics.

Sound‐Based Assembly of Magnetically Actuated Soft Robots Toward Enhanced Release of Extracellular Vesicles

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Magnetic soft robots offer promise in biomedicine due to their wireless actuation and rapid response, but current fabrication methods are complex and have limited cellular compatibility. A new, contactless bioassembly strategy using hydrodynamic instabilities is introduced, enabling customizable, centimeter‐scale robots.

Pulsed Electromagnetic Fields: A Novel Attractive Therapeutic Opportunity for Neuroprotection After Acute Cerebral Ischemia

open access: yesNeuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Objectives Acute cerebral ischemia is characterized by several pathological processes evolving during time, which contribute to the final tissue damage. Secondary processes, such as prolonged inflammatory response, impaired mitochondrial function and oxidative stress, are responsible for the progression of brain injury to the peri‐infarct area,
