Polymers used on low earth orbit (LEO) spacecraft surface suffer from an ultraviolet (UV) irradiation and orbital atomic oxygen (AO) erosion. These degradations may change the total electron emission ...

Scheiner and Zierkiewicz, however, have been studying apical carbon atoms in propellane and pyramidane molecules, where the bonding situation is rather different. Along with Mariusz Michalczyk, also ...

Boosting the selectivity in oxygen electrocatalysis using chiral nanoparticles as electron-spin filters In this study, chiral gold nanoparticles with a concave vortex cube structure were employed as ...

Manipulation of the spin state holds great promise to improve the electrochemical activity of transition metal-based catalysts. However, the underlying relationship between the nonplanar metal ...

Orbital Outpost X, a Silicon Valley space technology startup formerly called Space Villages, received a $5 million convertible note from Space Infrastructures Ventures of the Netherlands.

Different from the viewpoint of nanostructuring, this work focuses on an intriguing dynamic orbital hybridization approach to renormalize the disordering spin configuration in porous noble-metal–free ...

Louisville’s Sierra Space Corp. has achieved in recent weeks several important milestones in projects the aerospace spinoff of Sierra Nevada Corp. is undertaking as part of NASA contracts.

These data show that microbial long-distance electron transport can occur under a wide range of bottom water O₂ concentrations. However, the growth rate was notably slower at lower oxygen ...

The Falcon 9-launched configuration would spread 29,996 satellites across 12 orbital inclinations at altitudes between 328 and 614 kilometers altitude.
