Dimensionally Resolved Nanostructures of an Atomically Precise and Optically Active 1D van der Waals Helix

open access: yesAdvanced Materials, EarlyView.
The ability to grow nanostructures based on inorganic helical crystals with long‐range order will enable a platform to realize physical states that arise from chirality. Herein, it is demonstrated that controlled vapor phase deposition of an atomically precise helical crystal, GaSI, into ultrathin 1D nanowires and quasi‐2D nanoribbons.

Proton Selective Nanoporous Atomically Thin Graphene Membranes for Vanadium Redox Flow Batteries

open access: yesAdvanced Materials, EarlyView.
A scalable high‐performance proton‐exchange‐membrane architecture is demonstrated that integrates monolayer CVD graphene with Ar plasma‐engineered Angstrom‐scale proton‐selective pores, stacked to mitigate non‐selective defects, and interfaced with an ultrathin (≈300 nm) polybenzimidazole layer sandwiched between two Nafion 211 sheets.

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 ...

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
