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

Advanced Functional Materials, EarlyView.Multifunctional atomic layer deposited coatings and interface treatments enhance direct solar water splitting on GaAs/GaInP tandem cells. Optimized TiO2/Pt nanoparticle bilayers ensure durability and catalytic efficiency with minimal optical losses, while H2 plasma pretreatments maximize photovoltage and interfacial charge extraction.

Periodicities in Solar Radio Noise Emission [PDF]
Australian Journal of Physics, 1959 In a recent article, Roberts (1958) described solar radio wave emissions in the range 40-80 Mc/s. The investigations were a continuation of work initiated earlier by Wild and McCready (1950) on the dynamic radio-frequency spectrum, and by Wild, Murray, and Rowe (1954) employing a 40-240 Mc/s spectrograph.

Advanced Functional Materials, EarlyView.This work reports the self‐assembly of a pyrene derivative into two distinct nanostructures and their application in visible‐light photocatalysis. The two nanostructures exhibit completely different yet complementary photocatalytic activities, promoting either H2 or H2O2 evolution.

Advanced Functional Materials, EarlyView.The versatile precursor‐assisted soft sphere close packing during slot‐die coating is investigated with in situ X‐ray scattering. The soft crystallization pathways towards a close packing involve multistep structural transitions such as surface nucleation, in‐plane, and out‐of‐plane crystallization.
