We report a new type of core-shell heterostructure consisting of a rod-like NiCo2S4 (NCS) core and an urchin-like Ni(1-x)Co x (OH)2 (NCOH) shell via a simple hydrothermal route coupled with a facile electrodeposition. NCS nanorod arrays (NRAs) can not only act as excellent electrochemically active materials by themselves, but they can also serve as(More)
This paper presents closed-form solutions for the problem of long-term satellite relative motion in the presence of J 2 perturbations, and introduces a design methodology for long-term passive distance-bounded relative motion. There are two key ingredients of closed-form solutions.One is the model of relative motion; the other is the Hamiltonian model and(More)
In the title complex, [Zn(C18H10N4O2)(CH4O)], the Zn(2+) cation is located on a mirror plane and is coordinated by a tetradentate Schiff base ligand anion (L (2-)) and a methanol mol-ecule. The Zn(2+) cation is surrounded by two N atoms and two O atoms from L (2-), in a nearly planar configuration, and one methanol O atom, forming a slightly distorted(More)
