Observations of Circularly Polarized Radio Emission from the “Quiet” Sun at Frequencies <100 MHz

The Astrophysical Journal
The presence of the magnetic field makes the solar coronal medium birefringent. Research indicates that an appreciable degree of circular polarization (DCP) can be observed in the thermal radio emission at frequencies

Exploring Pb‐Chelation Chemistry in the Crystallization Dynamics of Halide Perovskites

Advanced Functional Materials, EarlyView.
A mechanism of how Pb‐chelation chemistry governs coordination geometry and initial nucleation behavior at the precursor level of halide perovskite, by regulating the deprotonation state of a chelating additive, is elucidated. This allows for innovative reaction‐system design principles that promote coherent growth while suppressing defect formation in

3D Printing Innovations in Polymeric Porous and Patterned Architecture

Advanced Functional Materials, EarlyView.
Polymeric foams occupy a unique structural space between dense solids and open networks, where engineered void fraction governs mechanical compliance, thermal resistance, and mass transport. Additive manufacturing now enables precise spatial control over cellular architecture, unlocking designer foam structures across applications spanning crash ...

Rotational modulation and local time dependence of Saturn's infrared H3+ auroral intensity [PDF]

, 2012
Planetary auroral emissions reveal the configuration of magnetospheric field-aligned current systems. In this study, Cassini Visual and Infrared Mapping Spectrometer (VIMS) observations of Saturn's pre-equinox infrared H3+ aurorae were analysed to show ...

Development of solar flares and features of the fine structure of solar radio emission [PDF]

Geomagnetism and Aeronomy, 2017
The reason for the occurrence of different elements of the fine structure of solar radio bursts in the decimeter and centimeter wavelength ranges has been determined based on all available data from terrestrial and satellite observations. In some phenomena, fast pulsations, a zebra structure, fiber bursts, and spikes have been observed almost ...

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.

Spectroscopic Imaging of the Sun with MeerKAT: Opening a New Frontier in Solar Physics

The Astrophysical Journal
Solar radio emissions provide several unique diagnostics to estimate different physical parameters of the solar corona, which are otherwise simply inaccessible. However, imaging the highly dynamic solar coronal emissions spanning a large range of angular
