Topological Spin‐Texture Transitions in van der Waals Magnets Revealed by X‐Ray Fourier Transform Holography

open access: yesAdvanced Materials, EarlyView.
Applied here for the first time to a 2D material, high‐resolution synchrotron x‐ray Fourier transform holography directly images topological spin textures in Fe3GeTe2. Combined with atomistic tight‐binding simulations including itinerant electrons and Rashba spin‐orbit coupling, the approach reveals labyrinth, skyrmion, and mixed phases, and uncovers ...

A Multifunctional Ionograsper Enabling Ion‐Redistribution Proximity Sensing and Structural‐Reconfiguration‐Driven Bidirectional Actuation

open access: yesAdvanced Materials, EarlyView.
A solid‐state ionic actuator integrates sensing, actuation, and memory within one material. A brief UV pulse induces long‐lasting deformation via coupled network rearrangement, dehydration, and rehydration, while ionic redistribution enables self‐powered sensing, supporting multifunctional, energy‐efficient soft robotic functions without continuous ...

Redox‐Confined Interfacial Polymerization Enables Mechanically Robust and Self‐Adhesive Nanofilms

open access: yesAdvanced Materials Interfaces, EarlyView.
Redox‐confined polymerization of a simple thiol monomer at a water‐organic interface generates robust freestanding films with nanoscale thickness. The resulting disulfide‐crosslinked nanofilms combine high stiffness with intrinsic adhesion to soft substrates, enabling conformal contact with artificial skin without additional functionalization.

The uniaxial compressive strength of concrete: revisited

open access: yesMaterials and Structures
AbstractThis paper re-examines common notions and conventions regarding the compressive strength of concrete in general and of the uniaxial compressive strength of concrete in particular. A distinction is introduced between the strength of the specimen and the strength of the concrete as a material, and the commonly measured and adopted strength is ...

Deep Eutectic Solvent‐Enhanced PEDOT: PSS/NR Foam Piezoresistive Sensor for High‐Sensitivity Wearable Devices and Sleep Monitoring Applications

open access: yesAdvanced Materials Interfaces, EarlyView.
A high‐performance piezoresistive foam sensor is developed by integrating natural rubber, PEDOT: PSS, and a deep eutectic solvent (DES). DES effectively detaches insulating PSS from PEDOT, dramatically amplifying electrical conductivity and sensitivity.

Skin‐Like Tri‐Modal Sensors Based on Soft Piezoelectric and Ionic Composites

open access: yesAdvanced Materials Technologies, EarlyView.
Inspired by the multimodal perception of human skin, a soft, skin‐like tri‐modal sensor is presented. The device incorporates an ionically conductive, piezoelectric, elastic composite as its active layer, enabling independent detection of temperature, static strain, and dynamic strain within a single two‐terminal architecture.
