| 1 | Three-dimensional carbon framework as high-proportion sulfur host for high-performance lithium-sulfur batteries显示文摘Lithium-sulfur(Li-S)batteries are anticipated as one of the most promising candidates for the highenergy-density storage systems.However,the insulating nature and shuttling effect of sulfur severely limits their performance.The incorporation of sulfur with carbon materials has been deemed as one of the most powerful strategies to improve electrical conductivity and suppress soluble polysulfide shuttling.Herein,a novel three-dimensional carbon framework(3DCF)is prepared and employed as a sulfur host(3DCF@S)for Li-S batteries.The 3DCF not only supplies abundant paths for lithium ion diffusion and electron transport,but also strengthens polysulfide immobilization during the lithium/sulfur conversion reactions.As a result,the 3DCF@S with high sulfur content of 90%exhibits a high capacity of 1366 mA h/g at 0.1 C and excellent cycling stability with a satisfactory capacity of 601 mA h/g after 600 cycles at 2.0 C.The resultant Li-S button battery based 3DCF@S electrode could power a light-emitting diode for 2 h.The acquired 3DCF@S is expected to be widely used in Li-S batteries and this study will promote developments of carbon/sulfur composites for Li-S batteries. | Xianbin Liu Zechen Xiao Changgan Lai Shuai Zou Ming Zhang Kaixi Liu Yanhong Yin Tongxiang Liang Ziping Wu | 2020 | Journal of Materials Science & Technology2020，47，13： | 4 |
| 2 | Phytic acid-modified CeO_(2) as Ca^(2+) inhibitor for a security reversal of tumor drug resistance显示文摘Ca^(2+)plays critical roles in the development of diseases,whereas existing various Ca regulation methods have been greatly restricted in their clinical applications due to their high toxicity and inefficiency.To solve this issue,with the help of Ca overexpressed tumor drug resistance model,the phytic acid(PA)-modified CeO_(2) nano-inhibitors have been rationally designed as an unprecedentedly safe and efficient Ca2+inhibitor to successfully reverse tumor drug resistance through Ca^(2+)negative regulation strategy.Using doxorubicin(Dox)as a model chemotherapeutic drug,the Ca^(2+)nano-inhibitors efficiently deprived intracellular excessive free Ca2+,suppressed P-glycoprotein(P-gp)expression and significantly enhanced intracellular drug accumulation in Dox-resistant tumor cells.This Ca^(2+)negative regulation strategy improved the intratumoral Dox concentration by a factor of 12.4 and nearly eradicated tumors without obvious adverse effects.Besides,nanocerias as pH-regulated nanozyme greatly alleviated the adverse effects of chemotherapeutic drug on normal cells/organs and substantially improved survivals of mice.We anticipate that this safe and effective Ca^(2+)negative regulation strategy has potentials to conquer the pitfalls of traditional Ca inhibitors,improve therapeutic efficacy of common chemotherapeutic drugs and serves as a facile and effective treatment platform of other Ca^(2+) associated diseases. | Zhimin Tian Junlong Zhao Shoujie Zhao Huicheng Li Zhixiong Guo Zechen Liang Jiayuan Li Yongquan Qu Dongfeng Chen Lei Liu | 2022 | Nano Research2022，15，5： | 0 |
