Kooperative Redox‐Katalyse der N2O‐Zersetzung mittels auf Co3O4 geträgerten RhOx‐ und CeOx‐Spezies mit kurzreichweitiger Wechselwirkung

open access: yesAngewandte Chemie, EarlyView.
A short‐range Rh‐O‐Co‐O‐Ce interfacial moiety drives low‐temperature N2O decomposition via a cooperative redox cycle. Operando modulated‐excitation XAS with phase‐sensitive detection (ME‐XAS+PSD) tracks rapid, reversible Rh oxidation coupled to Co reduction. Combined kinetics and DFT rationalize the activity trends and identify the Rh‐O‐Co interface as

Material‐Driven Neuronal Oscillators and Filters via Active Reactance in CC‐NDR and VC‐NDR Electro‐Thermal Memristors

open access: yesAdvanced Physics Research, EarlyView.
Active reactance in electro‐thermal memristors emerges intrinsically from rapid thermal switching of device resistance, linking current‐controlled and voltage‐controlled negative differential resistance to neuronal spiking dynamics. Opposing temperature coefficients of resistance give rise to active inductive or capacitive responses, enabling tunable ...
