To mitigate the water pollution problem by photocatalytic degradation of typical antibiotics of tetracycline(TC),we prepared defective Bi_(2)Sn_(2)O_7(BSO)quantum dots(QDs)with a full spectral response due to Bi metal deposition,using a one-pot hydrothermal method,labeled as Bi@*** optimized Bi@BSOOV showed 73.4% removal of TC in 1 h under irradiation with a 50 W LED lamp in the wavelength band in the visible-near-infrared(vis-NIR)light,a rate that is substantially greater than that of pure BSO(14.7%).The synergistic interaction of Bi metal and oxygen vacancies(OVs)is crucial to boosting photocatalytic *** near-infrared region of the photo-response is extended by the surface plasmon resonance(SPR)effect of Bi metal,enhancing the photocatalytic performance and dramatically raising the efficiency of solar energy *** addition to inducing defect levels in BSO,the OVs also activate the surface adsorbed O_(2) to promote the production of·O_(2)^(-)and ^(1)O_(2).DFT calculations reveal that Bi metal and OVs can mutually tune the charge transfer *** the one hand,Bi metal can act as both a charge transfer bridge and an electron donor to assist charge *** the other hand,OVs-induced defect levels allow electrons that leap to the conduction band(CB)to first leap from the valence band(VB)to the defect levels,notably improving interfacial charge separation and *** concept of design executed in this study for altering the catalyst by introducing both OVs and Bi metal can provide a rational design idea and potential insight for improving the photocatalytic activity for environmental applications.

中缝背核在甲基苯丙胺诱导小鼠条件性位置偏爱中的作用

目的研究中缝背核(dorsal raphe nucleus,DRN)在甲基苯丙胺(methamphetamine,METH)成瘾中的作用。方法将C57BL/6J小鼠随机分为METH模型组和对照组。通过腹腔注射METH(2mg/kg)制备条件性位置偏爱(conditioned place preference,CPP)动物模型,对照组注射等量生理盐水。经即刻早基因c-Fos免疫组织化学染色、含Ca^(2+)指示剂病毒载体脑内注射、化学遗传学和蛋白质谱分析等技术,探究METH激活DRN脑区情况及蛋白表达变化,并分析抑制DRN脑区神经元CPP评分的变化。结果CPP评分显示,METH模型小鼠在伴药箱产生明显偏好(t=4.438,P<0.05)。METH模型组DRN内c-Fos阳性细胞数较对照组显著增多(t=4.065,P<0.05),而且DRN神经元内Ca^(2+)荧光信号明显增强(t=20.50,P<0.001)。通过叠氮平-N-氧化物(clozapine-N-oxide,CNO)腹腔注射(3mg/kg)诱导hM4Di表达抑制DRN神经元兴奋性,明显降低了METH模型组小鼠CPP分数(t=3.26,P<0.05)。蛋白质谱分析在METH模型组DRN脑区筛出了一批差异蛋白,其中突触囊泡蛋白1(Syt1)和细胞黏附分子1(Cadm1)表达升高(均P<0.05);神经束蛋白(Nfasc)和突触小泡蛋白2(SV2)的C亚型表达降低(均P<0.05)。结论DRN脑区在METH诱导小鼠CPP行为偏好中起着重要作用,METH特异性诱导DRN内与突触相关的蛋白分子的表达,可能与DRN参与的成瘾机制有关。

GeTe-based compounds have been intensively studied recently due to their superior thermoelectric performance, but their real applications are still limited so far due to the drastic volume variation that occurs during the rhombohedral–cubic phase transition, which may break the material or the material/electrode interface during ***, superior performance and high service stability for GeTe-based thermoelectric compounds are achieved by co-doping Mg and Sb into *** linear coefficient of thermal expansion before phase transition is greatly improved to match that after phase transition, yielding smooth volume variation around the phase transition ***, co-doping(Mg, Sb) in GeTe successfully tunes the carrier concentration to the optimal range and effectively suppresses the lattice thermal conductivity.A peak z T of 1.84 at 800 K and an average z T of 1.2 in 300–800 K have been achieved in ***, a Ni/Ti/Ge0.85Mg0.05Sb0.1Te thermoelectric uni-leg is fabricated and tested, showing quite good service stability even after 450 thermal cycles between 473 K and 800 *** study will accelerate the application of GeTe-based compounds for power generation in the mid-temperature range.
