Progress of MXenes‐based responsive materials for soft sensors and actuators

Responsive Materials, EarlyView.
MXene, a promising 2D material, excels at mimicking human sensing and feedback system, making it ideal for intelligent robots. This review first covers its structure, properties, and synthesis. It then summarizes recent MXene‐based sensors and actuator.

Design and Control of a Dual‐Coil Magnetic Guidewire for Smooth and Adaptive Curvature Steering in Vascular Intervention

SmartBot, EarlyView.
Magnetic guidewires enable remote navigation in tortuous vasculature but often suffer from limited controllability, inefficient force transmission, and safety risks at bifurcations. This work presents a dual‐coil magnetic guidewire actuated by an external permanent magnet, enabling two steering modes with smooth curvature control and improved axial ...

Charge Transport Across Single Molecules at the Metal–Superconductor Interface

Small, EarlyView.
The evolution of Andreev reflection in single‐molecule junctions is probed with the decreasing distance between a normal‐metal tip and a conventional superconductor. Andreev reflection becomes most effective when a molecular orbital straddles the Fermi level.

Large‐Area Metallic Nanohelices for Engineering Optical Chirality

Small, EarlyView.
By exploiting the nanoscale engineering of residual stresses in metallic thin films, this method enables scalable fabrication of submicrometer metallic helices with tunable geometry and material versatility. The resulting structures exhibit pronounced chiroptical responses across the mid‐ to near‐infrared range, offering a robust platform for chiral ...

Correlation‐Driven d‐Band Modifications Promote Chemical Bonding at 3d‐Ferromagnetic Surfaces

Small, EarlyView.
Electron correlation at the oxygen‐passivated Fe(100) surface renormalizes and narrows the Fe d‐bands, enhancing their energetic overlap with the frontier orbitals of adsorbed pentacene. This strengthens hybridization and converts a weakly bound interface into a chemisorbed hybrid system, illustrating how correlation‐tuned d‐bands can be used to ...

Modular Donor‐Acceptor Diradicaloids Based on an Electron Deficient N‐Heteroacene Acceptor

Small, EarlyView.
This work presents a modular approach to donor‐acceptor‐donor (D‐A‐D) diradicaloids that show systematic evolution of their energy gaps, singlet‐triplet splittings, and diradical character (y). The correlation of (opto)electronic, spin, and magnetic properties with high‐fidelity theoretical investigations provides clear connections between the degree ...

Impact of Structural Heterogeneities in Hierarchically Grown Microribbons on 2D WS2 Monolayer on the Measured Local Hydrogen Evolution Activity on Au Substrate

Small, EarlyView.
Spatially resolved SECCM measurements reveal that hierarchically grown microribbons on 2D WS2 drastically suppress local HER activity. Relative to the basal plane of the 2D monolayer directly supported on an Au substrate, single‐layer and multilayer microribbons exhibit more than a ∼5‐fold and >10‐fold decrease in current density, respectively.
