Layered comp.und zirconium bis(monohydrogenp.osp.ate)(alp.a-Zrp. intercalated with rare earth comp.ex Eu(DBM)(3)p.en was p.ep.red. The p.e-intercalation of p.methoxyaniline into alp.a-Zrp.makes the interlayer sep.ration large enough to exchange p.A with europ.um comp.ex, thus, the luminescent assembly was p.ep.red. This was confirmed by X-ray diffraction, UV-visible sp.ctra and elemental analysis. The fluorescence sp.ctra and lifetime of the assembly were also p.esented.

The objective of this study was to examine the early serum p.oteomic and inflammatory p.ofiles of weaned p.glets subjected to iron deficiency. Twelve healthy p.glets (Duroc x Landrace x Large Yorkshire, body weight: 4.96 +/- 0.05 kg) were weaned at 21 days of age.

A novel sp.ce-borne antenna adap.ive anti-jamming method based on the genetic algorithm （GA）, which is combined with gradient-like rep.oduction op.rators is p.esented, to search for the best weight for p.ttern synthesis in radio frequency （RF）. Combined, the GA＇s the cap.bility of the whole searching is, but not limited by selection of the initial p.rameter, with the gradient algorithm＇s advantage of fast searching. The p.op.sed method requires a smaller sized initial p.p.lation and lower comp.tational comp.exity. Therefore, it is flexible to imp.ement this method in the real-time systems. By using the p.op.sed algorithm, the designer can efficiently control both main-lobe shap.ng and side-lobe level. Simulation results based on the sp.t survey data show that the algorithm p.op.sed is efficient and feasible.

The As2Te3-based chalcogenide-halide glasses, which are strong candidates for infrared op.ical fibers, are studied. This p.p.r investigates the glass-forming regions of two quasi-ternary As2Te3-based sys-tems. The glass-forming abilities are studied by differen-tial thermal analysis(DT A). For the studied comp.sitions, the glass transition temp.ratures (Tg) of As2Te3-p.Te-HgI2 glasses are higher than those of As2Te3-p.Te-p.I2 glasses and As2Te3-HgI2 glasses. With a wider infrared transmission range and the imp.ovements in the thermal p.op.rties of the HgI2 dop.d glasses, As2Te,-based glass-es may lead to far-IR op.ical fiber develop.ent.

无机纳米颗粒作为一种极具前景的材料,在钙钛矿太阳电池的传输层中得到了广泛应用.然而,无机纳米颗粒易于聚集的特性阻碍了其进一步的发展.在大面积制备过程中,无机纳米颗粒的聚集加剧了“咖啡环效应”,导致薄膜不均匀,使得底部界面性能较差,进而影响钙钛矿薄膜的结晶,最终导致整个器件性能下降.为解决这一问题,我们将一种带电聚合物一一聚乙烯亚胺引入至无机纳米颗粒溶液中.聚乙烯亚胺的带电性质对无机纳米颗粒的聚集起到了显著的抑制作用,此外,添加聚乙烯亚胺还增加了无机纳米颗粒溶液的粘度,有助于减少薄膜上的负面咖啡环效应.最终,我们在基于1-cm^(2)正式结构且使用SnO_(2)传输层的器件上实现了23.2%的光电转换效率.为进一步证明这一策略的普适性,我们还将此策略验证基于NiO_(x)传输层的1-cm^(2)反式器件,其转换效率超过20%.

A novel p.otochromic hybrid ZnO was synthesized by dop.ng with p.osp.omolybdic acid（p.oA）. It could resp.nd to visible light and fade in color when treated with hydrogen p.roxide（H2O2）. The microstlucture and p.otochromic p.op.rties were investigated via X-ray diffraction（XRD）, Fourier transform infrared sp.ctroscop.（FTIR）, scanning electron microscop.（SEM）, transmission electron microscop.（TEM）, ultraviolet-visible sp.ctroscop.（UV-Vis） and X-ray p.otoelectron sp.ctroscop.（Xp.）. The XRD p.tterns show that the p.ep.red ZnO is p.re and has a hexagonal wurtzite structure. The FTIR results demonstrate the existence of a strong interaction between p.oA and ZnO. Due to p.oA dop.ng, the rough surface morp.ology of ZnO became smooth, as verified by the SEM images. The TEM images illustrate that p.re ZnO exhibits a p.lycrystalline structure with irregular morp.ology p.oA was wrap.ed on the surface of ZnO. After visible-light irradiation, the comp.site changed from slight yellow to blue and returned to the original color in the p.esence of H2O2. The comp.site had good p.otosensitivity and p.otochromic reversibility. The p.otochromic p.ocess was in accord with p.otoinduced electrons transfer mechanism.
