A Retinomorphic Graphene Transistor Implementing Direction‐ and Velocity‐Selective Computation for In‐Sensor Image Stabilization

Small, EarlyView.
A multi‐gated ion‐gel graphene transistor architecture emulates spatiotemporal dendritic filtering inspired by biological direction‐selective retinal circuits. Leveraging distributed resistance‐capacitive ionic relaxation delays under combined excitation‐inhibition pulse routines, the solid‐state device exhibits programmable direction‐selective index ...

Optically Driven AuCu Alloying in Single Nanoparticles Revealed by In Situ TEM

Small, EarlyView.
In situ transmission electron microscopy with picosecond laser illumination reveals how single gold nanorods reversibly take up and release copper from their carbon support, forming homogeneous AuCu alloys. Laser fluence and illumination time serve as control parameters, making composition dynamically tunable, and with it the functional properties it ...

Fast and Selective Photochemical Doping of Spiro‐OMeTAD

Small Methods, EarlyView.
Sixty seconds of UV light converts spiro‐OMeTAD into its clean +1/+2 oxidized states while >98% of lithium is extracted into an aqueous phase by 12‐crown‐4. Proton‐tunable hydroxyl‐radical chemistry generates oxidants whose reduction potentials bracket the spiro2+/spiro3+ couple, providing thermodynamic oxidation‐state selectivity, as quantified by DFT.

Crash Behavior of DP800–DP1000 Advanced High‐Strength Steel’s Dissimilar Resistance Spot Welded Joints Under Quasi‐static and High Strain Rates

steel research international, EarlyView.
The high‐strain‐rate behavior of resistance spot‐welded DP800–DP1000 joints is investigated. Results show that microstructural gradients across BM–HAZ–FZ govern hardness, strain rate sensitivity, and failure modes. While strength increases with strain rate, energy absorption is controlled by ductility, with DP800–DP800 joints showing superior ...

Probabilistic estimation of reliable sensor spacing for wire break detection in prestressed concrete using acoustic emission technique

Structural Concrete, EarlyView.
Abstract The acoustic emission (AE) technique has proven to be an effective method for detecting individual wire breaks in prestressed concrete structures affected by stress corrosion cracking (SCC). However, despite its widespread application, the quantitative assessment of AE monitoring reliability and optimal sensor placement remains unresolved ...
