Strong Stabilization of Co Nanoparticles by CeO2‐x Clusters in Inverse CeOx/Co Catalysts for Enhanced CO2 Methanation

open access: yesAdvanced Materials, EarlyView.
Inverse CeOx/Co catalysts are promising new materials for CO2 methanation. Operando spectroscopy reveals that small, reducible CeO2‐x clusters effectively stabilize Co nanoparticles from sintering during H2 reduction and promote CO2 activation at the Co‐CeO2 interface.

Spatiotemporal Reservoir Computing with a Reconfigurable Multifunctional Memristor Array

open access: yesAdvanced Materials, EarlyView.
This study presents a hardware physical reservoir computing system using a tri‐modal memristive crossbar array. Stochastic masking, bistable nonlinear activation, and analog readout enable fully in‐memory spatiotemporal processing. Demonstrations on cellular automata, Lorenz prediction, ADHD EEG classification, and chaotic KS modeling highlight its ...

Role of Liquid Composition in the Transient Liquid Assisted Growth of Superconducting YBa2Cu3O7‐δ Films

open access: yesAdvanced Materials, EarlyView.
The Y supersaturation in the [Ba‐Cu(I/II)‐O] transient liquid composition is the driving force toward YBCO nucleation and growth in TLAG. Tuning the initial (Ba:Cu) molar ratio in the ink composition determines the YBCO epitaxial nucleation through supersaturation control.

Tunable Magnetism and Intrinsic Exchange Bias in Al‐Substituted Terbium Iron Garnet

open access: yesAdvanced Materials, EarlyView.
Al substitution in terbium iron garnet thin films enables continuous tuning of the magnetic compensation temperature from 190 K to above room temperature. Near compensation, a giant intrinsic exchange bias emerges, whose sign and stochasticity can be controlled by external fields and cooling history. This approach provides new routes to engineer garnet

Spin and Charge Control of Topological End States in Chiral Graphene Nanoribbons on a 2D Ferromagnet

open access: yesAdvanced Materials, EarlyView.
Chiral graphene nanoribbons on a ferromagnetic gadolinium‐gold surface alloy display tunable spin and charge states at their termini. Atomic work function variations and exchange fields enabe transitions between singlet, doublet, and triplet configurations.
