poisons for hunting and warfare. The Ebers papyrus (circa 1500 BC) describes several poisons known at that time. For example‚ it mentions hemlock as the state poison of the Greeks as well as opium‚ aconite and heavy metals such as lead‚ copper and antimony. Hippocrates (circa 400 B.C.) introduced clinical toxicology principles by describing elemental concepts of bioavailability and overdose. There are also several citations of the use of poisons in ancient Greece literature. It was Dioscorides‚ a Greek

In order to avoid the problem of mud cracks and decrease the resistivity‚ the Ti based ATO (antimony doped tin oxide) coating are prepared by thermal decomposition method on the surface of the porous titanium. The ATO coating was characterized and the preparation conditions were optimized. In the experiments‚ the sintering temperature and holding time both can promote the oxidization of the substrate Ti. Although the resistivity of ATO is higher than that of Ti‚ ATO coating can protect the substrate
