1Photocatalytic activity enhanced via surface hybridization显示文摘Surface hybrid inorganic semiconductors photocatalysts withπconjugated structure have recently been widely used in the field of photocatalytic environmental remediation and energy conversion.Surface hybridization is considered to be an efficient way to significantly enhance the photocatalytic activity by several times,completely inhibit photocorrosion of inorganic photocatalysts and expand the spectral response range of photocatalysts.This review provides a comprehensive overview of the surface hybridization definition,the principle of enhancing photocatalytic performance and the control factors of surface hybridization to promote photoactivity.Summarize the preparation and structural identification method of the surface hybrid photocatalyst.Special emphasis is placed on the various photocatalytic system construction of surface hybridization.The development of surface hybrid photocatalysts for pollutant degradation and energy conversion are further presented.Finally,the challenges and future development prospects of surface hybridization in photocatalysis are discussed.We hope this critical review can provide a clear picture of the state-of-the-art achievements and facilitate the applications of surface hybrid photocatalysts in environmental remediation and energy conversion.Yan Guo Huarui Li Wei Ma Wenxin Shi Yongfa Zhu Wonyong Choi 2020Carbon Energy2020,2,3:5
2健康男性的胰岛素抵抗指数、肥胖、血清PSA水平间的关系显示文摘本研究旨在确定血清PSA水平低于4ngmL^-1的健康男性的胰岛素抵抗指数、肥胖和血清前列腺特异性抗原(PSA)水平之间的关系。调查对象为韩国水力原子力株式会社的11827名健康男性职员,在2003年1月到2008年12月间接受了体检,体检项目包括空腹血糖水平、空腹胰岛素水平和血清PSA水平。用稳态模式评估法(HOMA;[空腹血糖水平×空腹胰岛素水平]/22.5)和定量胰岛素敏感性检验指数(QUICKI;1/[10g(空腹胰岛素水平)+log(空腹血糖水平)])测定胰岛素抵抗指数。协方差分析(ANOVA)和Duncan’s多重比较试验显示,随着用HOMA和OuICKI测定的胰岛素抵抗指数四分位的上升,年龄标化体重指数(BMI)也显著增加(P〈0.001)。多变量线性回归分析表明,相对于血清PSA水平,年龄、BMI、以及用HOMA或QUICKI测得的胰岛素抵抗指数都是显著的独立变量(P〈0.001)。本研究说明胰岛素抵抗指数和BMI都是血清PSA水平的独立变量,在健康男性体内,两者都与血清PSA水平呈负相关,两者之间呈正相关。June Hyun Han Yong Taec Lee Kyung Won Kwak Seung Hyun Ahn In Ho Chang Soon Chul Myung Seung Young Oh Yong-Seong Lee Wonyong Kim Young-Woo Jin Tae-In Choi Sook Hee Sung 2010Asian Journal of Andrology2010,12,3:2
3Weak magnetic field accelerates chromate removal by zero-valent iron显示文摘Weak magnetic field(WMF) was employed to improve the removal of Cr(VI) by zero-valent iron(ZVI) for the first time. The removal rate of Cr(VI) was elevated by a factor of 1.12–5.89 due to the application of a WMF, and the WMF-induced improvement was more remarkable at higher Cr(VI) concentration and higher p H. Fe2+was not detected until Cr(VI) was exhausted, and there was a positive correlation between the WMF-induced promotion factor of Cr(VI) removal rate and that of Fe2+release rate in the absence of Cr(VI) at pH 4.0–5.5. These phenomena imply that ZVI corrosion with Fe2+release was the limiting step in the process of Cr(VI) removal. The superimposed WMF had negligible influence on the apparent activation energy of Cr(VI) removal by ZVI, indicating that WMF accelerated Cr(VI)removal by ZVI but did not change the mechanism. The passive layer formed with WMF was much more porous than without WMF, thereby facilitating mass transport. Therefore,WMF could accelerate ZVI corrosion and alleviate the detrimental effects of the passive layer, resulting in more rapid removal of Cr(VI) by ZVI. Exploiting the magnetic memory of ZVI, a two-stage process consisting of a small reactor with WMF for ZVI magnetization and a large reactor for removing contaminants by magnetized ZVI can be employed as a new method of ZVI-mediated remediation.Pian Feng Xiaohong Guan Yuankui Sun Wonyong Choi Hejie Qin Jianmin Wang Junlian Qiao Lina Li 2015Journal of Environmental Sciences2015,27,5:2
