Enhanced Mechanical Recycling of Polymer Mixtures by a Trifunctional Dynamic Crosslinker

open access: yesAdvanced Materials, EarlyView.
A self‐catalyzed, trifunctional dynamic crosslinker that incorporates three desired properties into one system and is compatible with reactive extrusion can compatibilize waste plastic mixtures containing high Tm polymers and impart the recycled mixtures with superior thermoset properties such as enhanced creep resistance and thermomechanical stability

Mechanical degradation and microcrack evolution of weathered basalt under freeze–thaw cycles

open access: yesFrontiers in Earth Science
Freeze-thaw cycles (FTCs) play an important role in the degradation of rock masses and the stability of slopes in cold, high-altitude regions. However, the degradation behaviour of basalt with different weathering degrees under freeze-thaw (F-T ...

Weathering, atmospheric deposition and vegetation uptake: role for ecosystem sensitivity to acid deposition and critical load [PDF]

open access: yes, 2004
Critical loads of acidity represent the maximum acceptable atmospheric deposition for an ecosystem type. Two hundred and forty-one ecosystem types have been defined in France using pedologic, geologic and vegetation data.

Ti3C2Tx MXene/Silver Composite Foams For Lightweight, High‐Performance Electromagnetic Interference Shielding and Joule Heating

open access: yesAdvanced Materials Interfaces, EarlyView.
Ultrathin MXene/EMF composite foams achieve a specific shielding efficiency of 749.6 dB.dB·cm3$\mathrm{dB}\cdot {\mathrm{cm}}^{3}$/g, while the silver‐enhanced MXene/Ag/EMF reaches 81.4 dB shielding effectiveness at just 1.0 mm thickness. Both composites exhibit rapid Joule heating, retain stability up to 250∘C$^\circ{\rm C}$, and withstand 1000 ...

Ultra‐White Elastomeric Coatings for Daytime Radiative Cooling

open access: yesAdvanced Materials Technologies, EarlyView.
Passive daytime radiative cooling meets elasticity in a new class of ultra‐white silicone coatings. Combining high solar reflectance with strong sky‐window emission, they hold surfaces below ambient temperature under full sunlight while remaining flexible and stretchable. This combination of cooling performance and mechanical flexibility enables energy‐

An Electronic Nose Based Method for the Discrimination of Weathered Petroleum-Derived Products

open access: yesSensors, 2018
In recent years pollution due to hydrocarbon spills has increased markedly as a result of the numerous advances in technologies and industrial processes. Anthropogenic activities (accidental or illegal) are responsible for most of these incidents.

Moisture‐Adaptive Triboelectric Materials and Platforms: Design Strategies, Performance Enhancement, and Applications in Energy Harvesting and Wearable Electronics

open access: yesAdvanced Materials Technologies, EarlyView.
This review summarizes moisture‐adaptive strategies that enable triboelectric nanogenerators (TENGs) to operate across diverse moisture conditions. It examines moisture‐management methods, including exclusion, directional transport, removal, and utilization, with charge‐regulation approaches based on interfacial, dielectric, and structural engineering.

Analysis of the processes occurring in textile PPE against falls from a height under weather conditions [PDF]

open access: yesE3S Web of Conferences
The construction site is the leader in the number of injuries, among which a significant proportion are falls from a height. When carrying out work at height, PPE (personal protection equipment) and CPE (collective protection equipment) are used, which ...
