The COBRAS/SAMBA CMB Project
COBRAS/SAMBA is a second generation satelitte dedicated to mapping at high
resolution and sensitivity the anisotropies of the Cosmic Microwave Background
(CMB). This mission is in the assessment study phase (A) at ESA, with a
decision expected mid 1996, for a launch around 2003.Comment: PostScript, 4 pages, 4 figures in text, to appear in the Proceedings

Alginate electrodeposition onto three-dimensional porous Co-Ni films as drug delivery platforms
Three-dimensional porous Co–Ni films/alginate hybrid materials have been successfully prepared by electrodeposition to be used as a steerable magnetic device for drug delivery. Firstly, 3D porous Co–Ni films were prepared as substrates for the subsequent electrodeposition of the alginate biopolymer. Cyclic voltammetry, galvanostatic and potentiostatic studies were performed to establish the best conditions to obtain porous Co–Ni films. The electrochemical experiments were carried out in an electrolyte containing the metal salts and ammonium chloride at low pHs. In a second stage, the electrochemical deposition of alginate as a biocompatible polymer drug delivery carrier was performed. The characteristics of the alginate matrix were investigated in terms of electrochemical properties, morphology and drug release. The hybrid material obtained showed soft-magnetic behavior and drug release indicating its suitability to be used as a steerable magnetic drug delivery device.Postprint (author's final draft
