A series of four test flights of the SPHERES formation flying testbed was conducted aboard NASA’s KC-135 micro-gravity airplane in November 2003. These tests were sponsored by the Jet Propulsion Laboratory in Pasadena, CA, through the Terrestrial Planet Finder program, with the goal of advancing the progress of the SPHERES-TPF project prior to launch of the testbed to the International Space St...
Undoped and Tin (Sn) doped Molybdenum trioxide (α-MoO3) nanostructured thin films (which has lamellar (2D) structure) have been prepared using a simple and cost effective technique of spray pyrolysis on glass substrates at 450 ℃. Surface morphology, optical and structural properties of samples have been investigated using FESEM, UV-Vis spectroscopy and XRD analysis techniques, respectively. FES...
A micro manipulation platform consisting of two cubic centimeter sized micro robots each with four degrees of freedom has been developed. This paper discusses four different strategies of manipulation by adhesion for grasping, transferring and releasing a micro object. For each strategy, the interacting forces have been modeled and the results are compared with the real behavior of ∅ 40μm polle...
To overcome the low lithium ion diffusion and slow electron transfer, a hollow micro sphere LiFePO₄/C cathode material with a porous interior structure was synthesized via a solvothermal method by using ethylene glycol (EG) as the solvent medium and cetyltrimethylammonium bromide (CTAB) as the surfactant. In this strategy, the EG solvent inhibits the growth of the crystals and the CTAB surfacta...
