Spatially Decoupling Heating and Evaporation for Convection‐Enhanced 3D Solar Evaporation With Continuous Salt Harvesting

Advanced Functional Materials, EarlyView.
An architecture‐enabled bottom‐heated 3D solar convective evaporator spatially decouples photothermal heating from evaporation, triggering natural convection that intensifies sidewall vapour removal and heat transfer. The system achieves significantly enhanced evaporation rates over 2D and conventional 3D designs while confining salt precipitation to ...

Solar flux emergence : a three-dimensional numerical study

, 2008
Flux is continually emerging on the Sun, making its way from the solar interior up into the atmosphere. Emergence occurs on small-scales in the quiet Sun where magnetic fragments emerge, interact and cancel and on large-scales in active regions where ...

Steering Oxygen Activation Pathways via Redox Dual‐Defects in 2D Hydrated WO3 for High‐Yield Singlet Oxygen Evolution

Advanced Functional Materials, EarlyView.
Redox dual‐defects (Cs substitution and O vacancies) in 2D hydrated WO3 steer O2 activation toward selective singlet oxygen evolution. WO‐CO achieves 8.6–15.8 times higher 1O2 production than single‐defect or pristine catalysts, enabling efficient pollutant mineralization via a pathway‐selective photocatalytic mechanism.

Two Intermittent Eruptions of a Minifilament Triggered by a Two-step Magnetic Reconnection Within a Fan-spine Configuration

The Astrophysical Journal
Although numerous works have concentrated on minifilament eruption in complex configurations, the detailed triggering mechanism is still an open question. Using the observational data from the New Vacuum Solar Telescope and Solar Dynamics Observatory, we

Integrated Visible Light and Oxidant Protection Through Multifunctional Sunscreens

Advanced Healthcare Materials, EarlyView.
High‐energy visible radiation (HEVR), although less energetic than UV light, penetrates deeper into the skin and contributes to photoaging, pigmentation disorders, and oxidative stress. The development of new HEVR‐targeted filters, therefore, represents not only a scientific challenge but also a pressing public health and cosmetic industry need.

Evolution and dynamic properties of photospheric plasma in solar active regions [PDF]

, 2017
. This work has been done for the initiation of the author into the field of solar physics. The work is divided in two main blocks. The first part gives an overview of topics in solar physics taking a journey from the center of the Sun starting in the ...
