CO2‐Assisted Hydrolysis of NaBH4: A Multi‐Function Platform for Enhanced Hydrogen Release, Regeneration of NaBH4, and CO2‐to‐CH4 Conversion

Advanced Science, EarlyView.
CO2 significantly accelerates hydrogen release from aqueous NaBH4 without metal catalysts, eliminating the need for downstream separation. Ball‐milling the hydrolytic products with Mg regenerates NaBH4 with yields exceeding 76% while simultaneously producing methane.

Expounding structures of roller compacted concrete dam specimens by means of hard conventional X-ray inspection

Heliyon, 2019
A simple solution to improve the contrast between the different concrete composites in X-ray imaging (radiography and tomography) of a highly compressed composite sample of real size roller compacted concrete (RCC) specimens is presented. This is made by

Al─N Co‐Doped LLZO Solid Electrolytes via One‐Step Sintering: Toward High Ionic Conductivity

Advanced Science, EarlyView.
Al–N co‐doped LLZO solid electrolytes were prepared via a one‐step sintering process, which not only simplifies fabrication process, but also diminishes Li loss during high‐temperature sintering in conventional fabrication process. The Al–N co‐doped LLZO achieves a high ionic conductivity of 2.19 × 10−3 S cm−1 because the co‐doping reduces the energy ...

Sulfonated Bathocuproine Derivatives as Chemically Bonded Buried‐Interface Engineers for n–i–p Perovskite Solar Cells

Advanced Science, EarlyView.
A BCP‐derived buried‐interface strategy establishes Na‐BCS as a chemically bonded molecular bridge. By combining sulfonate anchoring to SnO2 with preserved BCP–Pb2+ coordination, Na‐BCS simultaneously passivates oxide‐ and perovskite‐side defects, suppresses non‐radiative recombination, and delivers a surface recombination velocity of 8.6 cm s−1, a ...

Bridged h‐BN Nanosheets Coatings: Simultaneous Shielding Atomic‐Oxygen Irradiation and Achieving Superior Friction Performance

Advanced Science, EarlyView.
ABSTRACT To confront extreme space environments, a combination of inorganic and organic coatings can provide a pathway for offering highly durable radiation resistance and anti‐friction simultaneously. Herein, a strong interfacial 3D hydrogen‐bonding network is designed to create robust hexagonal boron nitride (h‐BN) based polymer coatings with ...
