ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.A one‐pot metal–ammonia synthesis enables uniform Mn2O3 nanoparticle deposition on activated carbon, yielding composites with excellent electrochemical performance in supercapacitors. The method maximizes manganese utilization, eliminates toxic solvents, and achieves 34% of the theoretical maximum capacitance, significantly outperforming existing Mn–C ...

The CCD instrument background of the SMILE SXI
Earth and Planetary PhysicsThe ESA and CAS SMILE mission orbit is highly elliptical and will pass through multiple radiation environments. The Soft X-ray Imager (SXI) instrument aboard has a radiation shutter door designed to close when the surrounding radiation flux is high.

X-Ray Polarized View of the Accretion Geometry in the X-Ray Binary Circinus X-1
The Astrophysical Journal LettersCir X-1 is a neutron star X-ray binary characterized by strong variations in flux during its eccentric ∼16.6 day orbit. There are also strong variations in the spectral state, and it has historically shown both atoll and Z state properties.

CdCl2 Treatment for Cu2ZnSn(S,Se)4: A Method to Enhance the Solar Cell Performance
Progress in Photovoltaics: Research and Applications, EarlyView.We present, for the first time, two alternative CdCl2 treatments applied to solution‐processed kesterite (CZTSSe) absorbers: pre‐selenization and post‐selenization. Carrier concentration is consistently increased by either route, whereas the band gap decreases with pre‐selenization but remains nearly constant with post‐selenization; enhanced defect ...

Sb2Se3 Thin Films for Doping the Absorber in CdTe Solar Cells
Progress in Photovoltaics: Research and Applications, EarlyView.This study introduces for the first time a new doping route for CdSeTe/CdTe solar cells: A thin Sb2Se3 layer is deposited on the absorber, diffusing Sb into CdTe via subsequent CdCl2 treatment. With this approach, Sb‐doped devices reach efficiencies as high as conventional Cu‐doped cells, while showing much greater stability under accelerated ...
