Ratiometric Mycotoxin Detection in Living Plants With Dual‐Emissive Nanosensors
A minimally invasive microneedle patch integrates carbon dot‐embedded metal–organic frameworks as nanosensors to detect a key fungal toxin in living plants. The nanosensor produces a ratiometric fluorescence signal that enables early, non‐destructive diagnosis of fungal infection before visible symptoms, offering a new biomaterials‐based strategy for ...

Asphalt aging and its anti-aging mechanism based on quantum chemistry
To study asphalt aging and its anti-aging mechanism, the Frontier Orbital theory, Fukui Function, and Density Functional Theory are applied.The data reveals that 65 nm UV light can dissociate O2 into O radicals during UV aging. Among the resin components,

Molecularly engineered self‐assembled monolayers (SAMs) featuring extended conjugated terminals facilitate superior interfacial coupling with the organic solar cell active layer. By physically anchoring the local morphology, this design suppresses thermal degradation, allowing devices to operate at 85°C for 150 h before degrading to 90% of their ...

A general, versatile laser‐shock synthesis process is reported to produce various bimetallic CuNi, CuFe, CuCo, and medium‐entropy CuFeCoNi heterostructures, in which crystalline metal nanoparticles are anchored to amorphous hydroxide supports. During nitrate reduction reaction, the heterostructures undergo dynamic amorphous/crystalline reconstruction ...

Plasticity enhancement in metallic glasses via aging-assisted ultrasonic vibrations
The aging of glassy materials is an inevitable process leading to progressive property degradation. In metallic glasses (MGs), aging-induced property degradation poses a persistent challenge to their applications.

This project developed a smart bandage‐like patch (a microneedle array) for repairing diabetic bone damage. It intelligently senses signals from infection and inflammation, then releases its medicines in a specific, timed sequence: first an antibacterial agent, then an anti‐inflammatory agent, and finally growth factors.

Neutron Reflectometry and Compression of Graded Hydrogel Surfaces
Highly‐entangled and covalently‐crosslinked hydrogels with thin and thick surface gel layers are compressed in neutron reflectometry experiments. Surface gel layer thickness dictates the extent to which the polymer network at the surface of a hydrogel collapses, while crosslinking chemistry, and therefore elastic modulus, impacts the pressure at which ...
