High‐Density Boron Nitride Nanotube Composites via Surfactant‐Stabilized Lyotropic Liquid Crystals for Enhanced Space Radiation Shielding

Advanced Functional Materials, EarlyView.
High‐density BNNT films, enabling mechanical robustness and high space radiation shielding effectiveness, are fabricated using surfactant‐stabilized BNNT liquid crystal. Simulations indicate that a 50 g cm−2 BNNT film can reduce radiation exposure by 56% compared to zero shielding, potentially doubling the duration of astronaut missions on the lunar ...

Differentiating the Synergistic Interactions Between Li+ Salts and Cyclic to Linear Carbonate Ratios to Enable Wide‐Temperature Performance of Lithium‐Ion Batteries

Advanced Functional Materials, EarlyView.
The coordination in carbonate solvents and degradation products of lithium difluoro(oxolato) borate (LiDFOB) salt enables sufficient passivation of both LiNi0.8Mn0.1Co0.1O2 (NMC811) cathode and graphite anode in the absence of ethylene carbonate (EC).

Does total column ozone change during a solar eclipse? [PDF]

Atmospheric Chemistry and Physics
Several publications have reported that total column ozone (TCO) may oscillate with an amplitude of up to 10 DU (Dobson units) during a solar eclipse, whereas other researchers have not seen evidence that an eclipse leads to variations in TCO beyond the ...

Interfacial Chemistry Control of In Situ Grown Gold Nanoparticles on Functionalized MXene Nanosheets

Advanced Materials Interfaces, EarlyView.
Gold nucleation on MXene is governed by interfacial oxidation, not termination density. An interface‐resolved pathway is uncovered in which Au nucleates at TiO2/TiOx, guided by local reduction at the surface; where tailored functionalization directs when and where nuclei form, enabling the formation of predictable heterostructures.

Accuracy of Solar Eclipse Calculation Algorithm Based on Jet Propulsion Laboratory Data Nasa

Al-Ahkam, 2020
DE200 and DE405 are Development Ephemeris (DE) series released by the National Aeronautics and Space Administration (NASA) in 1981 and 1997. NASA uses DE405 to predict solar eclipses in 2011-2020.
