31. These have now largely been replaced by KTN ( potassium tantalate niobate ) and barium titanate ( BaTiO3 ). 32. This effect was first discovered in the 1960s . barium titanate ( BaTiO 3 ) and many other materials. 33. "' Caesium titanate "'is an inorganic compound with the formula Cs 2 TiO 3. 34. One example is the tendency of strontium titanate to form oxygen vacancy defects under high temperatures in high vacuum. 35. They were inspired to make this prediction based on superconducting transitions, and the ferrorelectric transition in barium titanate . 36. At IBM his research for almost 15 years centered on SrTiO 3 ( strontium titanate ) and related perovskite compounds. 37. Altairnano has also deployed their lithium titanate energy storage systems for electric grid ancillary services and in various military applications. 38. The two have mismatched crystal spacing that produces strain within the strontium titanate layer that makes it less stable and tunable. 39. A nano lithium-titanate battery stores 72 Wh / kg and can provide a power of 760 W / kg. 40. The Proterra EcoRide BE35 uses lithium-titanate batteries and is able to fast-charge in less than 10 minutes.
