Efficient Magnetization Switching Driven by Orbital Torque in Light 3d Transition‐Metal Nitrides

Advanced Functional Materials, EarlyView.
Efficient magnetization switching is demonstrated through orbital torque generated from light 3d transition‐metal nitride. Transition‐metal nitrides are established as effective sources of orbital angular momentum for current‐induced switching, highlighting their potential for low‐power next‐generation orbitronic devices beyond conventional heavy‐metal‐

The image-forming mirror in the eye of the scallop

, 2017
Scallops possess a visual system comprising up to 200 eyes, each containing a concave mirror rather than a lens to focus light. The hierarchical organization of the multilayered mirror is controlled for image formation, from the component guanine ...

Poisson's Ratio‐Driven Control of Myogenic Differentiation and Maturation in Auxetic Metamaterials under Dynamic Mechanical Stimulation

Advanced Functional Materials, EarlyView.
This study explored how innovative “auxetic” scaffolds, which expand when stretched, influence skeletal muscle development. Researchers cultured muscle cells on different scaffold designs and applied repeated stretching over 10 days. They found that scaffold geometry affected muscle cell differentiation and fiber formation.

REMINISCE: refurbishment of mirrors to increase sustainability at light sources

Optics Damage and Materials Processing by EUV/X-ray Radiation (XDam9)
Contamination or damage to X ray optics is becoming increasingly problematic for beamlines at 3rd and 4th generation storage rings and FEL sources. Carbon contamination, induced by ultra intense photon beams, can cause a major loss in flux, focusing power, and specific absorptions which are detrimental to spectroscopy.

Hydrogel‐Based Method for High‐Resolution Measurements of Contact Mechanics in Rapid Biological Adhesives: A Case Study in Cuttlefish Tentacle Strikes

Advanced Functional Materials, EarlyView.
Cuttlefish and squid can catch their prey within milliseconds using specialized tentacles and suckers. The physics of how the suckers can attach so quickly has remained a mystery given the technical challenges of studying them in vivo. In this publication, we develop a hydrogel that retains imprints of the suckers in order to estimate the forces they ...

Architected Bio‐Based Iontronic Skin With Dual‐Mode Pressure and Strain Sensing

Advanced Functional Materials, EarlyView.
Bio‐based acrylates in combination with an ionic liquid create 3D‐printed ionogels with compositionally tuneable mechanics and ionic conductivity. Gyroid architectures amplify low‐pressure sensitivity while preserving robust strain sensing, enabling dual‐mode detection of pressure and deformation.

Voltage Gated Ion Entry Into Two‐dimensional Angstrom‐Scale Channels

Advanced Functional Materials, EarlyView.
We demonstrate voltage‐gated ion transport through artificial Å‐scale slit channels (∼4 Å high) formed by van der Waals assembly of 2D materials. At low electric fields, ions are excluded while water permeates. Above a threshold voltage, nonlinear hysteretic conduction emerges, driven by ion dehydration and concentration‐dependent barriers, mimicking ...

One‐Component Carbon Dot Photoinitiator Enables High‐Fidelity Digital Light Processing 3D Printing With Improved Mechanical Resistance

Advanced Functional Materials, EarlyView.
Furfural carbon dots functionalized with acylphosphine oxide photosensitive groups (CD‐PO PI) demonstrate potential as one‐component photoinitiators for digital light processing (DLP) 3D printing. Compared to conventional diphenyl(2,4,6‐trimethylbenzoyl)phosphine oxide (TPO), CD‐PO PI offers improved printing resolution, resin toughness, and biological

Single‐Cell Resolution Mapping of Osteoarthritis‐Associated Chondrocyte Dynamics Using a High‐Density CMOS MEA Platform

Advanced Healthcare Materials, EarlyView.
Single‐cell and spatially resolved impedance mapping using a high‐density CMOS‐MEA platform enables non‐invasive monitoring of osteoarthritis‐associated chondrocyte dynamics. Continuous label‐free measurements reveal heterogeneous remodeling behaviors, including proliferation, migration, and phenotypic transitions, establishing a powerful approach for ...
