Electrically Induced Phase Transition and Synaptic Functionality in MoTe2/Graphene Memristors

Advanced Functional Materials, EarlyView.
An electrically induced reversible 2H ↔ 1T′ phase transition is demonstrated in a vertical Au/Ti/MoTe2/graphene memristor with a laterally contacted graphene electrode. Resistive switching proceeds through a compositionally invariant amorphous/2H ↔ amorphous/1T′ transformation, in which a self‐formed amorphous MoTe2 interfacial region is proposed to ...

Electrical‐Programming‐Free Neural Crossbars Enabled by Photochemical Weight Patterning

Advanced Functional Materials, EarlyView.
A flexible neural‐crossbar hardware system enabled by electrical‐programming‐free, mask‐defined, array‐parallel photochemical weight patterning is demonstrated. Trained weights are physically implemented across the array, supporting multilevel programming, bending‐stable operation and reconfiguration, substrate reuse, and low‐energy readout while ...

Accelerated Discovery of Topological Spin Phase Diagrams in CrSBr Magnets Via High‐Throughput Optimization

Advanced Functional Materials, EarlyView.
Here, we develop a high‐throughput algorithm that accelerates the elucidation of phase diagrams of topological spin textures using limited computational resources at high numerical accuracy. Applying this framework to the van der Waals magnet CrSBr, we unveiled a hierarchy of previously unknown topological textures (domain‐wall bimerons, bimeron chains,

An authentication architecture for cross-domain mobility

, 2006
The rapid growth of wireless device technologies is enabling seamless mobility, but there are still major concerns related to the performance of security. The handoff performance correlates with inter-wireless link switch latency and network layer latency, with security being required at both levels.

Eliminating Centralized Trust in VANETs: A Blockchain-Assisted SSL-PUF Authentication and Cross-Domain Key Agreement Scheme

International Journal of Distributed Sensor Networks
Vehicular ad hoc networks (VANETs) enable secure vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications but still rely heavily on centralized trusted authorities, creating scalability limitations, single-point failures, and increased

How the Porous Transport Layer Dictates Membrane Electrode Assembly Performance of IrO2 Catalysts

Advanced Functional Materials, EarlyView.
The Schottky barrier formed at the catalyst | PTL interface critically governs both the initial performance and long‐term durability of the PEMWE, and its magnitude is dictated by the catalyst's work function. This limitation can be resolved by combining a rutile IrO2 core for efficient electron transfer with an amorphous IrOx shell for high surface ...
