Co-existence of two plasma phases in solar and AGN coronas [PDF]
Serbian Astronomical Journal, 1998 Here we have juxtaposed two distant cosmic locations of the Sun and AGN where neutral hydrogen appears in a close connection with hot coronas. Besides the solar photosphere, chromosphere and prominences where the presence of neutral hydrogen is ...

Advanced Materials, EarlyView.This review examines passive, active, and hybrid liquid manipulation strategies, highlighting hybrid approaches as an emerging route to reconcile energy efficiency with adaptive control. By actively reconstructing passive surfaces to store programmable interfacial energy, hybrid systems enable flexible yet low‐power liquid transport, with perspectives ...

Advanced Materials, EarlyView.Mixed‐cation lead mixed‐halide perovskites suffer from structural instabilities linked to nanoscale heterogeneity. To probe this non‐destructively, a low‐dose, concurrent 4D‐STEM and EDX methodology has been developed. Examining a (FA0.83Cs0.17)Pb(I0.8Br0.2)3 film revealed a complex mosaic of coexisting crystal structures. Crucially, local deficiencies

Cu‐Pd Dual Single Atoms Promoting Selective CO2 Photoreduction to C2 Products in Seawater
Advanced Materials, EarlyView.Cu and Pd dual single atoms anchored on TiO2 cooperatively enhance C─C coupling during CO2 photoreduction in seawater. Under xenon‐light irradiation and without a sacrificial reagent/alkaline trapping agent, the catalyst achieves highly selective acetic acid formation.

Conditions for Solar Prominence Formation Triggered by Single Localized Heating
The Astrophysical JournalWe performed numerical simulations to study mechanisms of solar prominence formation triggered by a single heating event. In the widely accepted “chromospheric-evaporation condensation” model, localized heating at footpoints of a coronal loop drives ...
