RF magnetron sputter-deposition of La{sub 0.5}CoO{sub 3}//Pt composite electrodes for Pb(Zr,Ti)O{sub 3} thin film capacitors
La{sub 0.5}Sr{sub 0.5}CoO{sub 3} (LSCO) thin films have been deposited using RF magnetron sputter-deposition for use as an electrode material for PZT (PbZrTiO{sub 3}) thin film capacitors. Effect of O{sub 2}:Ar sputter gas ratio during deposition, on LSCO film properties was studied. It was found that the resistivity of the LSCO films deposited at ambient temperature decreases as the O{sub 2}: Ar ratio was increased for both as-deposited and annealed films. It was also found that thin overlayers of LSCO tend to stabilize the underlying Pt//Ti electrode structure during subsequent thermal processing. The LSCO//Pt//Ti composite electrode stack has a low resistivity and provides excellent fatigue performance for PZT capacitors. Furthermore, the LSCO//Pt//Ti electrode sheet resistance does not degrade with annealing temperature and the electrode does not display hillock formation. Possible mechanisms for the stabilization of the Pt//Ti electrode with LSCO overlayers are discussed

The use of induced pluripotent stem cells in drug development.
Induced pluripotent stem cell (iPSC) technology is revolutionizing medical science, allowing the exploration of disease mechanisms and novel therapeutic molecular targets, and offering opportunities for drug discovery and proof-of-concept studies in drug development. This review focuses on the recent advancements in iPSC technology including disease modeling and control setting in its analytical paradigm. We describe how iPSC technology is integrated into existing paradigms of drug development and discuss the potential of iPSC technology in personalized medicine
