Stabilizing Electrochemical Interfaces With Multifunctional Cobalt Nitride Layers
Advanced Materials Interfaces, EarlyView.Cobalt nitrides emerged recently as an interesting class of earth‐abundant oxygen evolution catalysts. Herein, plasma‐enhanced atomic layer deposition is used to synthesize multifunctional cobalt nitride layers that simultaneously protect and catalytically activate photoelectrode surfaces.

Quantifying the Contamination of TESS Ecliptic-plane Light Curves by Minor Planets
The Astronomical JournalThough missions devoted to time series photometry focus primarily on targets far beyond the solar system, their observations can be contaminated by foreground minor planets, especially near the ecliptic plane, where solar system objects are most ...

Integrated photogrammetry and photoclinometry for enhanced 3D surface reconstruction of asteroids
Astronomy & AstrophysicsStereo photogrammetry (SPG) and stereo photoclinometry (SPC) are the main techniques used in the 3D surface reconstruction of asteroids. The SPG approach retrieves accurate 3D geometry with limited spatial resolution, while SPC extracts fine-scale ...

Advanced Materials Interfaces, EarlyView.Ultrathin MXene/EMF composite foams achieve a specific shielding efficiency of 749.6 dB.dB·cm3$\mathrm{dB}\cdot {\mathrm{cm}}^{3}$/g, while the silver‐enhanced MXene/Ag/EMF reaches 81.4 dB shielding effectiveness at just 1.0 mm thickness. Both composites exhibit rapid Joule heating, retain stability up to 250∘C$^\circ{\rm C}$, and withstand 1000 ...

Collective Gravity of Minor Planets In The Outer Solar System
, 2021 Axisymmetric disks of eccentric Kepler orbits are susceptible to the inclination instability, an out-of-plane buckling characterized by exponentially growing inclinations, decreasing eccentricities, and clustering in argument of periapsis.
