photoactive ternary tb3 zn2 centered hybrids with p tert butylcalix 4 arene functionalized si o bridge and Polyvinylpyridine
Inorganic Chemistry Communications, 2010Co-Authors: Hai-yan Zhang, Xiao-fei Qiao, Bing YanAbstract:Abstract A new multifunctional linkage Calix-AC-Si is derived from the modification of the p-tert-butylcalix[4]arene derivative with 3-(triethoxysilyl)-propyl isocyanate (TEPIC) and behaves as the first chelated ligand, and the organic polymer Polyvinylpyridine (PVPD) is used as the second terminal ligand, whose ternary hybrids of metal ions (Tb3+ and Zn2+) are assembled and possess different luminescent properties. Especially the introduction of Zn2+ in the Tb3+ hybrid system can improve the luminescence of Tb3+.

The Lithium/Iodine-Polyvinylpyridine Battery – 35 years of Successful Clinical Use
2016Co-Authors: Curtis F. HolmesAbstract:The lithium/iodine-Polyvinylpyridine (PVP) battery has been in clinical use as a power source for pacemakers for 35 years. Since 1972, literally millions of lithium/iodine cells have seen clinical use, providing health-giving and life-saving therapy to patients throughout the world. Indeed, the battery has compiled an excellent record of reliability and safety. The cell reaction is the simple combination of lithium and iodine to form lithium iodide, but the chemistry of the cathode material is interesting and complicated

The Lithium/Iodine Battery: A Historical Perspective
Pacing and Clinical Electrophysiology, 1992Co-Authors: Wilson Greatbatch, Curtis F. HolmesAbstract:The lithium/iodine-Polyvinylpyridine battery, first implanted 20 years ago, has become the power source of choice for the cardiac pacemaker. Over the last 20 years, improvements in cell chemistry, cell design, and modeling of cell performance have been made. Cells today exhibit an energy density over three times as great as cells produced in 1972. Well over 2 million pacemakers have been implanted with this chemistry, and the system has exhibited excellent reliability.
