The Sun's Global Photospheric and Coronal Magnetic Fields: Observations and Models

Living Reviews in Solar Physics, 2012
In this review, our present day understanding of the Sun’s global photospheric and coronal magnetic fields is discussed from both observational and theoretical viewpoints. Firstly, the large-scale properties of photospheric magnetic fields are described,

Polyzwitterionic Organohydrogel and Soft Composite with Tunable Sol–Gel Properties Enabling On‐Demand Functionalization with Colloids

Advanced Science, EarlyView.
Poly[2‐(methacryloyloxy)ethyl]dimethyl‐(3‐sulfopropyl)ammonium hydroxide‐based organohydrogels are formed via nonsolvent‐induced gelation, featuring tunable viscoelasticity. Functional fillers (MXene nanosheets, magnetic NdFeB microparticles) enable electrical, magnetic, and mechanical responsiveness for applications in mechano‐tunable electromagnetic ...

Solar intense magnetic fields

, 1980
The nature of motions in intense magnetic fields is investigated. For a flux tube in a uniform atmosphere a dispersion relation is derived for the modes of vibration and analytic approximations are obtained for a slender tube. In a stratified atmosphere an expansion procedure is used to derive an equation for the vertical velocity perturbation.

Photochromism‐Driven Full Solar Spectrum Absorption for Efficient Photo‐Thermo‐Electric Conversion

Advanced Science, EarlyView.
After electron‐transfer photochromism, a black viologen‐based organic compound shows full solar spectrum absorption (250–2500 nm) and near‐infrared photothermal conversion efficiency (NIR‐PCE) >60%. Integrated with a thermoelectric generator, it outputs 1.17 V under 4 Suns irradiation, enough to drive a small fan via photo‐thermo‐electric conversion ...

Room‐Temperature Alane Dehydrogenation for Visible‐Light‐Driven Photocatalytic Hydrogen Supply System

Advanced Science, EarlyView.
In situ formed Al/MOF enables viable visible‐light‐driven photocatalytic dehydrogenation of alane (AlH3) confirming practical application. Results demonstrate that Al nanoparticles prolong lifetime of photogenerated charge carriers via localized surface plasmon resonance induced hot electron injection, while AlH3 chemisorption triggers interfacial ...

Defect Engineering Activates Pyrene‐Based Covalent Organic Frameworks for Efficient Photocatalytic Uranium Capture

Advanced Science, EarlyView.
A defect‐engineered pyrene‐based covalent organic framework (TP‐PYTO‐SA) is developed via strategic salicylaldehyde incorporation. This approach simultaneously enhances hydrophilicity and introduces uranyl coordination sites, while optimized defect density significantly improves charge separation.
