Design of an interplanetary ultralow-noise three-dimensional energetic particle spectrometer

地球与行星物理论评
The origin and acceleration of solar and heliospheric energetic particles have been prevalent research frontiers in space physics. Solar and heliospheric energetic particles measured in the interplanetary medium (IPM) can be classified into two major ...

Self‐Adaptive Anhydrous Passivation Mitigates Open‐Circuit Voltage Loss in Pb‐Sn Mixed Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
In this report, a self‐adaptive anhydrous passivation strategy is introduced by incorporating trimellitic anhydride (TMAH) into the perovskite precursor. In situ hydrolysis of TMAH yields trimellitic acid (TMA); ‐C═O/‐COO− groups of TMAH/TMA form a chelate with undercoordinated Pb2+/Sn2+, regulate nucleation, promote (100) orientation, passivate ...

Particle precipitation during ICME-driven and CIR-driven geomagnetic storms [PDF]

, 2008
Interplanetary coronal mass ejections (ICME) and corotating interaction regions (CIR) alter the parameters of the solar wind and interplanetary magnetic field (IMF) that affect conditions in the Earth's magnetosphere and particle precipitation in the ...

The Evolution of Research on Abundances of Solar Energetic Particles

, 2021
Sixty years of study of energetic particle abundances have made a major contribution to our understanding of the physics of solar energetic particles (SEPs) or solar cosmic rays.

Nanoengineered Binetworks in Multifunctional Anionic Block Polymer Mesoblends for Improved Mechanical Properties

Advanced Functional Materials, EarlyView.
Mesoblends consist of a nanostructured polymer into which a second polymer is imbibed with a selective solvent. In this work, a solvent‐templatable pentablock terpolymer possessing a sulfonated midblock is modified with a hydrophilic polymer that is photocrosslinked in situ, yielding a hierarchical binetwork.

Relativistic-electron dropouts and recovery: A superposed epoch study of the magnetosphere and the solar wind [PDF]

, 2009
During 124 high-speed-stream-driven storms from two solar cycles, a multispacecraft average of the 1.1–1.5 MeV electron flux measured at geosynchronous orbit is examined to study global dropouts of the flux. Solar wind and magnetospheric measurements are

First imaging of corotating interaction regions using the STEREO spacecraft [PDF]

, 2008
Plasma parcels are observed propagating from the Sun out to the large coronal heights monitored by the Heliospheric Imagers (HI) instruments onboard the NASA STEREO spacecraft during September 2007. The source region of these out-flowing parcels is found

Designed Lewis Acid–Base Passivation for High Performance Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
ABSTRACT Silicon's high cost and long energy payback time remain major barriers to the global expansion of solar power. In contrast, metal–halide perovskites offer abundant, solution‐processable absorbers, and have achieved efficiencies of 25%–30%, positioning them as strong competitors to silicon.

Large gradual solar energetic particle events

Living Reviews in Solar Physics, 2016
Solar energetic particles, or SEPs, from suprathermal (few keV) up to relativistic ( ∼ few GeV) energies are accelerated near the Sun in at least two ways: (1) by magnetic reconnection-driven processes during solar flares resulting in impulsive SEPs, and (2) at fast coronal-mass-ejection-driven shock waves that produce large gradual SEP events.
