Disorder Beats Order: Carbon Microstructure Steers Radical Versus Cationic Pathways in Kolbe Electrolysis

open access: yesAngewandte Chemie, EarlyView.
Less graphitic, more Kolbe: carbon microstructure steers selectivity in Kolbe electrolysis. Disordered, sp3‐rich carbon electrodes with high charge‐transfer resistance favor surface radical pathways, giving about an order of magnitude more Kolbe dimer than graphitized sp2‐rich counterparts.

Mechanochemically Disordered Li2Ta2OCl10 Oxyhalide Unlocks Superionic Conductivity (>10 mS.cm−1)

open access: yesAdvanced Energy Materials, EarlyView.
This work presents a new crystalline oxyhalide, Li2Ta2OCl10, built from [Ta2OCl10]2− dimers. The disorder induced by ball‐milling drives the dramatic 5000‐fold increase in ionic conductivity to reach 11 mS.cm−1. The material shows promise as a solid electrolyte for batteries and opens new prospects for the discovery of new dimer‐based compounds ...

Redshifting TADF Emission With a Bora‐Triptycene Lewis Acid

open access: yesAngewandte Chemie, EarlyView.
Bathochromic emission shifting of donor–acceptor and multi‐resonant TADF emitters is achieved by adduct formation with a thia‐bora‐triptycene Lewis acid. TADF properties are retained on adduct formation whilst delivering > 100 nm redshift of the emission.

Chloride‐Mediated Activation of Aluminum‐Alloyed Liquid Metal Anodes for Stretchable Asymmetric Energy Storage

open access: yesAdvanced Energy Materials, EarlyView.
A gallium‐centered cell pairs an aluminum‐alloyed GaIn anode with a GaOOH cathode in a chloride‐rich water‐in‐ionic‐liquid electrolyte. Chlorogallate ions dissolve the native oxide that normally seals the liquid metal, and preferentially reduce indium seeds to oxide‐free clusters on which gallium plates and strips reversibly.

Direct Observation of Radical‐Mediated Oxide‐to‐Alloy Transformation in Solution Under Pulsed Laser Irradiation

open access: yesAngewandte Chemie, EarlyView.
Time‐resolved in situ x‐ray absorption spectroscopy and DFTB‐based molecular dynamics simulations identify direct hydrogen atom transfer from ethanol to lattice oxygen as the elementary step of laser‐driven reduction in NiCo2O4. While this transfer is facile, the subsequent release of lattice oxygen is entropy‐driven and becomes accessible only at ...

Compact Modeling of Volatile‐Switching Electrochemical Metallization Memory Cells by Means of the Electromotive Force

open access: yesAdvanced Intelligent Systems, EarlyView.
A volatile‐switching compact model of electrochemical metallization memory cells for neuromorphic architecture is developed and validated by reliable reproduction of device characterization measurements: I−V sweeps, SET kinetics, relaxation dynamics.

Optimizing Electrode Design for Functional Activation of Human Pluripotent Stem Cell‐Derived Cardiomyocytes

open access: yesAdvanced NanoBiomed Research, EarlyView.
Electrical stimulation of human pluripotent stem cell‐derived cardiomyocytes is systematically investigated as a function of electrode material and configuration. Stimulation efficiency is found to be governed predominantly by electrode geometry, with increased electrode area and proximity to cells enabling more effective pacing.
