Interaction With Surface Spins as a Contribution to Nuclear Magnetic Relaxation of Liquids Adsorbed in Mesoporous Materials

Magnetic Resonance in Chemistry, EarlyView.
Liquids at silica interfaces experience demixing as a consequence of their respective polarity. The distribution of liquids and their primary relaxation contributions are studied by surface modification with OD and radical moieties, respectively. ABSTRACT NMR relaxation of liquids in the presence of solid interfaces, such as silica gel or porous glass,

Study on the evolution of mechanical properties of hot dry rocks after supercritical CO2 injection

Geothermal Energy
Characterizing the evolution of mechanical properties of hot dry rock (HDR) after supercritical CO2 (CO2(sc)) injection is crucial for assessing the heat extraction rate and reservoir security of CO2 based enhanced geothermal systems. This study designed

Remote sensing and citizen science for habitat mapping: A machine learning approach to lowland heathland in Surrey, UK

People and Nature, EarlyView.
Abstract In a time of extensive global biodiversity loss, conservation efforts increasingly rely on high‐resolution, accurate, up‐to‐date habitat maps to guide decision‐making and strategic interventions. Many products have been developed in response, using machine learning (ML) methods to automate habitat classification, often relying on satellite ...

Impact of Waste‐Derived Slate Dust on Structural, Thermal, and Thermomechanical Behavior of Recycled Poly(Ethylene Terephthalate)

Polymer Composites, EarlyView.
This study investigates the use of waste slate dust as a filler in recycled PET. Incorporating up to 20 wt% slate dust caused no filler‐induced molecular degradation, increased the crystallization temperature, thermal conductivity, and storage modulus. ABSTRACT Recycled polyethylene terephthalate (rPET) is widely considered a sustainable alternative to

Oxidative Stability and Rheological Features in Recycled Composites Based on Postconsumer Polypropylene and Antioxidant‐Loaded Silicas

Polymer Engineering &Science, EarlyView.
Role of antioxidant supported on MCM‐41 and nano‐silica in enhancing oxidation induction time (OIT) and nucleation performance. ABSTRACT Plastic recycling efforts are hindered by the reduction of material properties in recyclates stemming from oxidative degradation of their polymeric chains.

Degradation of Crystalline Si‐Based Solar Modules With Varying Material Combinations—Part I: Encapsulant Degradation

Progress in Photovoltaics: Research and Applications, EarlyView.
This work deals with the degradation of solar modules with varying material combinations under accelerated aging conditions. By in situ moisture measurements and simulations of oxygen ingress, the consumption of stabilizing additives and polymer degradation can be correlated spatially resolved with the penetrating stressors.

Genomic insights into the local adaptation of spontaneous olive trees in the Mediterranean Basin highlight the need for conservation planning in the face of global change

PLANTS, PEOPLE, PLANET, EarlyView.
The Mediterranean Basin, a major biodiversity hotspot, is highly vulnerable to climate and global changes. Wild olive trees form an essential part of this landscape and hold strong ecological, cultural and socio‐economic significance. By examining how these trees responded to past climatic conditions, this study shows adaptation of olive trees to local
