X‐Functionality–Driven Photocatalytic Hydrogen Evolution in 2D 4‐X‐PEA2SnI4 Perovskites
Advanced Functional Materials, EarlyView.We report a water‐based synthesis of 2D 4‐X‐PEA2SnI4 perovskite microcrystals with prominent photocatalytic (PC) activity for H2 production. The synergy between organic functionalization and HI‐derived iodide scavenges holes suppress octahedral distortion, and favor electron accumulation, enabling a PC H2 evolution ∼20 µmol·g−1 and long‐term stability ...

Diagnosis of the solar atmosphere using solar oscillations [PDF]
Symposium - International Astronomical Union, 1988 I present a review of the art of using acoustic and gravity waves as a tool to probe the structure of the solar atmosphere. The principle ideas behind the technique are discussed and a small bouquet of results is presented. The current discrepancies are pointed out, and in the last section a few thoughts are let loose about the inversion of data to ...

A Self-consistent Mechanism for Heating the Solar Magnetic Atmosphere by Kinetic Alfvén Waves
The Astrophysical JournalCoronal heating remains a long-standing problem in solar and astrophysical plasmas. Alfvén waves (AWs) can carry sufficient energy into the solar atmosphere, but how this energy is dissipated into particle heating is not well understood.

Cosmic sources of the Earth's atmosphere ionization (review)
Геофизический журнал, 2017 Characteristics of the Earth's upper atmosphere vary constantly under the action of electromagnetic emission of the sun, solar wind, streams of galactic and solar cosmic rays as well as of precipitation of captured magnetosphere electrons.

Ambient‐Stable Transparent P‐Type CuI Transistors Via Room‐Temperature Pulsed Laser Deposition
Advanced Functional Materials, EarlyView.An in situ PLD fabricated AlOx${\rm AlO}_x$/CuI/AlOx${\rm AlO}_x$ sandwich structure enables stable CuI TFTs with a field‐effect mobility of 2.3 ±$\pm$ 0.7 cm2${\rm cm}^{2}$ V−1${\rm V}^{-1}$ s−1${\rm s}^{-1}$ and excellent ambient stability. Complementary inverters based on CuI:Rb and ZnO:Al exhibit rail‐to‐rail voltage transfer characteristics and an

Ultraviolet and extreme-ultraviolet emissions at the flare footpoints observed by atmosphere imaging assembly [PDF]
, 2013 A solar flare is composed of impulsive energy release events by magnetic reconnection, which forms and heats flare loops. Recent studies have revealed a two-phase evolution pattern of UV 1600 Å emission at the feet of these loops: a rapid pulse lasting ...

Evaluation of High Resolution WRF Solar
Energies, 2023 The amount of solar irradiation that reaches Earth’s surface is a key quantity of solar energy research and is difficult to predict, because it is directly affected by the changing constituents of the atmosphere.

Advanced Functional Materials, EarlyView.Combinatorial vapor deposition enables independent tuning of Cs/Pb and Br/Cl in wide‐bandgap perovskites. Automated multimodal mapping of 500+ compositions reveals a high‐energy optical transition that correlates with enhanced photoluminescence, defining a practical Cs/Pb window.

Effects of a mid-latitude solar eclipse on the thermosphere and ionosphere - A modelling study [PDF]
, 1998 A modelling study is presented which investigates in-situ generated changes of the thermosphere and ionosphere during a solar eclipse. Neutral temperatures are expected to drop by up to 40 degrees K at 240 km height in the totality footprint, with ...
