    Abstract: A surface modified lithium titanate and preparation method thereof is provided. In the surface modified lithium titanate, the deactivating groups distributed on the surface of the lithium titanate are —O—P—RR?R?, —O—P—(OR)R?R?, —O—P—(OR)(OR?)R?, and —O—P—(OR)(OR?)(OR?), where R, R? and R? are identical or different C1˜C8 alkyl or alkenyl groups. The deactivating groups are bonded to the lithium titanate via a bond or a bridge. The exemplary surface modified lithium titanate can effectively lower its catalytic activity, reduce the gassing of lithium ion batteries, and therefore improve the high temperature storage and high temperature cycle performance of lithium titanate batteries. The exemplary preparation method is simple, has great repeatability, a low cost, low pollution to the environment, and is suitable for industrial production.

  • Patent number: 8445710
    Abstract: The present invention provides phosphaplatins, stable isolated monomeric phosphato complexes of platinum (II) and (IV), and methods of use thereof for treating cancers, including cisplatin- and carboplatin-resistant cancers. Unlike cisplatin, these complexes do not readily undergo hydrolysis and are quite soluble and stable in aqueous solutions. Moreover, these complexes—unlike cisplatin, carboplatin, and related platinum-based anti-cancer agents—do not bind DNA. Rather, data suggests that phosphaplatins trigger overexpression of fas and fas-related transcription factors and some proapoptotic genes such as Bak and Bax. Nevertheless, the complexes exhibit tremendous cytotoxicity towards cancer cells. Thus, the present invention provides novel platinum anticancer agents that have a different molecular target than those in the art.

  • Patent number: 6767927
    Abstract: Stable rare earth tris (organophosphate) solutions comprise a rare earth tris (organophosphate) and a hydrocarbon solvent. From about 2% to about 10% rare earth element, preferably from about 3% to about 8%, is present in the solutions. The rare earth tris (organophosphate) solutions are stable from precipitation of the rare earth tris (organophosphate) for at least about fifteen (15) days, preferably for at least about twenty (20) days and most preferably at least about thirty (30) days. A process for preparing these solutions is described herein. A stabilizing additive, acid, glycol or mixtures thereof, is utilized to inhibit precipitation. The molar ratios of free acid, glycol and/or water to the rare earth element are controlled to inhibit precipitation.
