Defect modulation currently plays a decisive role in addressing the poor photoabsorption,sluggish electron hole separation,and high CO_(2)activation barrier in photocatalytic CO_(2)***,hunting for a straightforward strategy to balance the concentration of oxygen vacancy and metal cation defect in one photocatalyst is still a great ***,a bismuth vacancies BiOBr nanosheets(BiOBr-1)on the exposed[001]facets were constructed via an acetic acid molecule modification strategy,which can repair oxygen defect by bismuth vacancy in low-temperature solid-state chemical *** from the formed bismuth defects that can not only broaden light absorption and elevate charge separation efficiency,but also enhance adsorption and activation of CO_(2)molecules,the evolution rates of photocatalytic CO_(2)conversion into CO(71.23μmol·g^(-1)·h^(-1))and CH4(8.90μmol·g^(-1)·h^(-1))attained by BiOBr-1 are superior 7.1 and 11 times to that of plate-like *** photocatalytic mechanisms including adsorption concentration and activation process of CO_(2)are further revealed by the in situ diffuse reflectance infrared flourier transform spectra(DRIFTS).This finding of the existence of distinct defects in ultrathin nanosheets undoubtedly leads to new possibilities for photocatalyst design using two-dimensional materials with high solar-driven photocatalytic activity.

Background T-cell receptor （TCR） plays an important role in the development of autoimmune diseases. Recently, it was reported that immunization of animals with TCR peptide derived from the pathogenic cells could prevent autoimmune diseases. The aim of this study was to investigate whether vaccination with a synthetic peptide from the hypervariable region of TCR Vβ 8.3, an experimental autoimmune uveoretinitis （EAU）-associated gene, was able to prevent the disease. Methods EAU was induced in Lewis rats by immunization with IRBP R16 peptide emulsified in complete Freund＇s adjuvant （CFA）. The clinical and histological appearances were scored. Delayed type hypersensitivity （DTH） and lymphocyte proliferation were detected. Cytokine levels of aqueous humour, supernatants of cells from spleen and draining lymph nodes were measured by enzyme linked immunosorbent assay （ELISA）. Gene expression of TCR Vβ8.3 on CD4^＋ T cells was examined by real time quantitative polymerase chain reaction （PCR）. Results After vaccination, the intraocular inflammation was significantly mitigated, antigen specific DTH and lymphocyte proliferation responses were suppressed, interleukin （IL）-2 in aqueous humour, interferon （IFN）-γ and IL-2 produced by the spleen and draining lymph node cells were significantly decreased, whereas the production of IL-4 and IL-10 were increased. The response of draining lymph node cells to TCR Vβ 8.3 peptide was enhanced after vaccination. Inoculation with CFA alone did not affect the severity of EAU and the above parameters. The suppression of EAU was much stronger in the group of four fold inoculations than the group of two fold inoculations. The expression of TCR Vβ 8.3 gene was significantly reduced in the group of fourfold inoculations. Conclusion Vaccination with the synthetic TCR Vβ 8.3 peptide could remarkably inhibit the development of EAU.

倒伏一直以来都是制约东北黑土区玉米高产稳产的重要因素。为了进一步提高玉米抗倒伏能力,以先玉335为供试材料,在玉米大喇叭口期进行化控剂调控试验,探讨化控剂对玉米茎秆和根系抗倒性能的影响。结果表明:化控剂处理显著降低了株高、穗位高、植株下部节间长,显著提高了玉米气生根层数、总根条数、节间密度和折断力,因而化控剂的使用能明显增加玉米抗茎折和根系倒伏的能力。
