Bio‐Inspired Gradient Coatings Enhance the Leading Edge Erosion Resistance of Wind Blades

Advanced Science, EarlyView.
Rain‐induced erosion of the wind turbine blade leading edge poses a critical challenge to maintenance and operation. Here, we propose a bio‐inspired approach for erosion protection utilising a platelet‐reinforced polyurethane coating with a graded through‐thickness architecture.

Research on the Mechanism of Sequential Flares

The Astrophysical Journal
Coronal mass ejections exert significant influences on the space environment of Earth, which warrants particular attention. An important question in solar physics is why some large solar flares erupt successfully while others remain confined.

Van der Waals Heterostructures for Next‐Generation Spintronics: Multiferroic‐Mediated Magnetoelectric Properties

Advanced Science, EarlyView.
As CMOS technology approaches fundamental energy limits, new paradigms for low‐power information processing are required. Magnetic systems are attractive for their spin transport, yet current‐induced magnetization control is energy inefficient. Multiferroic heterostructures enable energy‐efficient electric field manipulation of magnetism.

Atmospheric Water Harvesting Through Polymer Hydrogel Sorbents: Materials Chemistry, Design Strategies, and Applications

Advanced Science, EarlyView.
Polymer‐based hydrogels have emerged as promising materials for atmospheric water harvesting (AWH) due to their high water affinity, tunable network structure, and excellent moisture adsorption‐desorption performance. Functional hydrogel systems enable efficient water capture and controlled release under low‐energy conditions, offering a sustainable ...

Aspects of three-dimensional MHD : magnetic reconnection and rotating coronae [PDF]

, 2010
Solutions of the magnetohydrodynamic (MHD) equations are very important for modelling laboratory, space and astrophysical plasmas, for example the solar and stellar coronae, as well as for modelling many of the dynamic processes that occur in these ...

Application of a Grid-constrained U-shaped Neural Operator in Real-time Solar Corona Magnetic Field Extrapolation

The Astrophysical Journal Supplement Series
In this study, we propose a neural network framework, called the Grid-constrained U-shaped Neural Operator (GC-UNO), for real-time extrapolation of the coronal magnetic fields of active regions (ARs).

The Link between Nonthermal Velocity and Free Magnetic Energy in Solar Flares

The Astrophysical Journal Letters
The cause of excess spectral line broadening (nonthermal velocity) is not definitively known, but given its rise before and during flaring, the causal processes hold clues to understanding the triggers for the onset of reconnection and the release of ...
