Review of Inorganic Separator Engineering for Next‐Generation Lithium–Sulfur Batteries: Compromise or Cornerstone?

Advanced Materials, EarlyView.
Inorganic compound‐modified separators transform lithium–sulfur batteries from passive polysulfide confinement to active reaction‐pathway regulation. A Practical Relevance Index (PRI)‐guided framework bridges interfacial chemistry of inorganic separators with practical constraints, establishing unified design principles for scalable, high‐energy ...

Atomic‐Scale Detection of Néel Vector Switching in the Single‐Layer A‐Type Antiferromagnet Cr2S3‐2D

Advanced Materials, EarlyView.
Interfacial electron donation from graphene redistributes charge within single‐layer Cr2S3‐2D, preferentially accumulating at the lower Cr/S plane. The resulting minute magnetic imbalance lifts the equivalence of the two magnetic sublayers, enabling atomic‐resolution identification and field‐induced control of Néel‐vector states in a two‐dimensional A ...

Satellite orbits and ephemerides

Celestial Mechanics, 1984
This review considers theoretical work leading to the actual knowledge of the motions of all planetary satellites, except the Moon. It covers recent calculations of inequalities of satellites’ motions and the determination of their orbits on the basis of existing observational data.

The Computation of Satellite Orbit Trajectories

1962
Publisher Summary This chapter focuses on the computation of satellite orbit trajectories. The post-Sputnik era has seen a phenomenal growth in the computation of the orbits of artificial satellites. There are literally dozens of installations actively engaged in computing orbits and in related research.

Orbit Control of a Recalcitrant Satellite

IFAC Proceedings Volumes, 1992
Abstract After the recovery of the OLYMPUS mission in mid August 1991 the orbit control of the satellite suffered from perturbations of daily attitude thruster firings. All orbital elements were affected in a dramatic way. Furthermore, additional constraints for the orbital correction manoeuvres arose from the attitude control mode applied and from ...

Satellite Orbits

The Physics Teacher, 1963
The various types of satellite and projectile orbits are described and related to the conditions, in terms of energy and angular momentum, under which the ideal orbits occur. The transient nature of the initial and final part of a satellite's path and the conditions necessary for placing a satellite in a given orbit are discussed.

Viking Satellite Orbit Determination

Journal of Guidance and Control, 1977
During the summer of 1976, the two Viking spacecraft, each consisting of an orbiter-lander combination, were inserted into orbit about Mars. The paper describes the experiences of the Viking Satellite Orbit Determination Team in determining Mars centered ephemerides of the orbiters and positions of the landers from the two-way Doppler and range data ...
