The present invention provides phosphaplatins, stable isolated monomeric phosphate 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.
A novel 2,5-diphenyl-1,3,4-oxadiazole-based fluorescent sensor for multi-analyte, ratiometric and relay recognition of a through modulating ESIPT has been developed.

The complex [(VIVO)bipy(H2O)]2(μ-P2O7)}·3H2O (2) was readily obtained as a nanocrystalline powder by one-pot synthesis under mild conditions. Single crystals of 2 were grown at room temperature over 2 months, and its structure was determined. Fundamental catalytic activity was proven for this species by testing for oxidation of benzyl alcohol in air.

The sluggish kinetics of Na+ in anode limits the rate capability of sodium-ion batteries (SIBs). Herein, pyrophosphate, as a Na+ pump in the cell membrane, is integrated with cobalt redox-active center to obtain a new type of anode material for SIBs with a highNa+ diffusion rate. After combining with the hierarchical carbon network, bichannel structure is formed to accelerate the transport of electrons
阳极中 Na +的缓慢动力学限制了钠离子电池 (SIB) 的倍率容量。在此,焦磷酸盐作为细胞膜中的 Na +泵,与钴的氧化还原活性中心结合,获得了一种新型的具有高 Na +扩散速率的 SIB 负极材料。与分级碳网络结合后,形成双通道结构,加速电子和离子的传输,碳网络作为电子和焦磷酸钠的传输通道。电子和离子的高电导率导致 CPOC@C-700 的高赝电容比(在 1 mV s -1时为 95%),表明其具有高倍率能力(在 5 A g 时为190.3 mA hg -1-1 )。一系列非原位表征证明了氧化还原中心的高可逆性和循环过程中双通道结构的稳定性。因此,CPOC@C-700 在 2 A g -1下循环 1000 次后仍保持 71.1% 的容量。这种双通道设计概念有望促进 SIB 的进一步应用。
