| 1 | Interface engineering of Zn meal anodes using electrochemically inert Al_(2)O_(3)protective nanocoatings显示文摘Aqueous rechargeable Zn-ion batteries are regarded as a promising alternative to lithium-ion batteries owing to their high energy density,low cost,and high safety.However,their commercialization is severely restricted by the Zn dendrite formation and side reactions.Herein,we propose that these issues can be minimized by modifying the interfacial properties through introducing electrochemically inert Al_(2)O_(3)nanocoatings on Zn meal anodes(Al_(2)O_(3)@Zn).The Al_(2)O_(3)nanocoatings can effectively suppress both the dendrite growth and side reactions.As a result,the Al_(2)O_(3)@Zn symmetric cells show excellent electrochemical performance with a long lifespan of more than 4,000 h at 1 mA·cm^(−2)and 1 mAh·cm^(−2).Meanwhile,the assembled Al_(2)O_(3)@Zn//V_(2)O_(5)full cells can deliver a high capacity(236.2 mAh·g^(−1))and long lifespan with a capacity retention of 76.11%after 1,000 cycles at 4 A·g^(−1). | Rui Wang Qiongfei Wu Minjie Wu Jiaxian Zheng Jian Cui Qi Kang Zhengbing Qi JiDong Ma Zhoucheng Wang Hanfeng Liang | 2022 | Nano Research2022，15，8： | 1 |
| 2 | Catalytic combustion of toluene on Pt/Al_(2)O_(3) and Pd/Al_(2)O_(3) catalysts with CeO_(2),CeO_(2)-Y_(2)O_(3) and La_(2)O_(3) as coatings显示文摘CeO_(2),La_(2)O_(3),and CeO_(2)-Y_(2)O_(3) oxides were coated on the surface of spherical granular AI_(2)O_(3)(3-5 mm)through impregnation method,and proved as better supports of Pd and Pt catalysts.The influences of rare earth metal doping on the adsorption rates of Pd and Pt ions,as well as the catalytic performance,were investigated.Results show that the H_(2)PtCl_(6)·6H_(2)O adsorption rates of the Al_(2)O_(3) carriers modified by Ce,La,and CeY increase significantly.These rare earth coatings can adsorb almost all H2PtCl_(6)·6H_(2)O in the solution.Compared with Pt/Al_(2)O_(3) catalyst,Pt/Ce-AI_(2)O_(3) and Pt/CeY-AI_(2)O_(3) catalysts have better degradation performance for toluene,and the T_(90) temperatures are both about 147℃.According to X-ray photoelectron spectroscopy(XPS)characterization,Pt^(0)is an important active species for catalytic oxidation reaction of toluene.After CeO_(2)modification to the conventional Pt/Al_(2)O_(3)catalyst,the proportion of Pt^(0)increases from 74.5%to 82.1%.When the Pt^(0)content in the metal state is improved,the redox activity of the catalyst is promoted correspondingly. | Bing Zhou Quanli Ke Meijun Wen Tianbiao Ying Guokai Cui Ying Zhou Zhenyu Gu Hanfeng Lu | 2023 | Journal of Rare Earths2023，41，8： | 0 |
| 3 | Potential Application of TCM Sophoridine in Regulating Intensity of Autophagy to Treat PKD显示文摘Nearly all cells have primary cilia( PC) composed of microtubules,primary cilia mainly functioning as sensing various signals of the environment and coordinating intracellular signaling pathways. Autophagy is an adaptive response of cells to environmental stress such as starvation/inflammation and infection. Many ciliopathies may induce autophagy. Polycystic kidney disease( PKD) is the most common ciliopathy,with the incidence of 1/500 to 1/1 000 in the world. A typical symptom of the PKD is the chronic development of multiple renal cysts that may eventually develop into advanced kidney disease. Sophoridine is an alkaloid extracted from the traditional Chinese medicinal plant Sophora alopecuroides L. It is a new antitumor drug which has the function of inducing cell autophagy. This paper mainly discussed the possibility of treating PKD through sophoridine inducing autophagy. | Guangqiang MA Yan LIN Hanfeng CUI Qinglong SHU Hongjiao WAN | 2018 | Medicinal Plant2018，9，4： | 0 |
| 4 | A mechanic insight into low-temperature catalytic combustion toward ethylene oxide over Pt-Ru/CuCeO_(x) bimetallic catalyst显示文摘The catalytic oxidation performance toward ethylene oxide(EO)and the consequent mechanism were investigated on the Pt-Ru/CuCeO_(x)bimetallic catalyst,which was prepared by a distinct method combining stepwise adsorption and subsequent impregnation.The catalytic tests show that the introduction of Ru into the Pt catalyst,so as to form Pt-Ru bimetallic active sites,can greatly increase the oxidation activity of the catalyst,as evidenced by the extremely lower full oxidation temperature(120℃)when compared with that of the Pt/CeO_(2) catalyst(160℃).The XPS spectra show that the Ru species(mainly RuO_(x))have strong interaction with the CuCeO_(x) support,which can therefore affect the electron transfer between the Pt species and the support.As a result,the oxygen activation on Pt species is obviously facilitated and catalytic activity is enhanced.Finally,in situ diffuse reflectance infrared Fourier transform spectroscopy(DRIFTs)was used to track the reaction mechanism.It is found that the catalytic oxidation process follows the MvK catalytic mechanism at low temperature and the L-H catalytic mechanism when the temperature moves to higher range. | Wenxi Zhou Kai Chen Quanli Ke Haoru Wang Xiao Chen Yufeng Liu Guokai Cui Xiaole Weng Ying Zhou Hanfeng Lu | 2023 | Journal of Rare Earths2023，41，6： | 0 |
