Post-synthetic installation strategy is an effective approach to improve the functions of metal-organic frameworks(MOFs).Herein,a pair of chiral MOFs is successfully constructed through solvothermal subcomponent self-assembly and exhibit circularly polarized luminescence(CPL).These MOFs contain coordinatively unsaturated Zn sites and channels,which allow the installation of pyridyl-terminated pillars into the original *** a post-synthetic installation process reinforces the MOFs'rigidity and increases the photoluminescence quantum yields(PLQYs).Furthermore,the luminescence dissymmetry factors(glum)of these post-modified MOFs are amplified after installing the *** work provides an appealing strategy for boosting the CPL performance of chiral MOFs.

BiIO4 nanoflakes were successfully prepared through a facile hydrothermal method. The as-prepared BiIO4 was characterized by scanning electron microscope(SEM), high-resolution transmission electron microscopy(HRTEM), X-ray diffraction(XRD), energy-dispersive spectroscopy(EDS) and ultraviolet visible diffuse reflectance spectroscopy. BiIO4 nanoflakes showed excellent photocatalytic activity for the degradation of phenol solution under simulated solar irradiation. The influence of synthesis temperature on the morphology, size and photocatalytic performance of BiIO4 was investigated. BiIO4 prepared under 140 ℃ exhibited the highest removal rate of phenol under simulated solar light irradiation. In addition, the parametric studies such as the effect of catalyst loading and phenol solution pH were carried out to optimize the reaction conditions. The active species trapping experiment demonstrated that h+ and ·OH are the major active species during the photocatalytic process.

多年来对克山病的研究证实,克山病的发病是与低硒的地理环境有关,病区人群全血中硒的含量低于非病区人群,病区人群含硒酶——谷胱甘肽过氧化物酶的活性水平亦低于非病区人群。从病区粮所饲养的仔猪心肌细胞膜、线粒体形态和功能的改变、脂质过氧化物的累积和血清乳酸脱氢酶的活性高于加硒组等可看出由于谷胱甘肽过氧化物酶活性降低,导致机体抗过氧化物作用降低,生物膜之脂质产生过氧化反应而引起代谢物的紊乱,最终引起细胞坏死。这是从谷胱甘肽过氧化物酶清除脂质过氧化物方面说明低硒和含硒酶谷胱甘肽

The DNA nuclease-like activity of a water soluble manganese corrole 5, 10, 15-tris（N-methyl-4-pyridyl）- corrolatomanga- nese（III）（MnⅢTMPyC） has been investigated. MnⅢMPyC may bind strongly to DNA via outside groove binding mode as indicated by absorption spectra, viscosity measurements and CD spectra. MnInTMPyC exhibited excellent catalytic activity in the DNA oxidative cleavage in the presence of hydroperoxide.
