Catalyst–support interaction plays a crucial role in improving the catalytic activity of oxygen evolution reaction(OER).Here we modulate the catalyst–support interaction in polyaniline-supported Ni_(3)Fe oxide(Ni_(3)Fe oxide/PANI)with a robust hetero-interface,which significantly improves oxygen evolution activities with an overpotential of 270 mV at 10 mA cm^(-2)and specific activity of 2.08 mA cm_(ECSA)^(-2)at overpotential of 300 mV,3.84-fold that of Ni_(3)Fe *** is revealed that the catalyst–support interaction between Ni_(3)Fe oxide and PANI support enhances the Ni–O covalency via the interfacial Ni–N bond,thus promoting the charge and mass transfer on Ni_(3)Fe *** the excellent activity and stability,rechargeable Zn-air batteries with optimum Ni_(3)Fe oxide/PANI are assembled,delivering a low charge voltage of 1.95 V to cycle for 400 h at 10 mA cm^(-2).The regulation of the effect of catalyst–support interaction on catalytic activity provides new possibilities for the future design of highly efficient OER catalysts.

U/U of the environmental sample can indicate the existence of uranium irradiation,and even can be uesd to estimate the burnup of nuclear spent fuel.A study on the burnup estimation of irradiated uranium which was mixed with natural uranium was carried out by measuring the U/U and U/U in the samples by using MC-ICP-MS. According to the equation(1) and(2),a programme for calculating the burnup of the irradiated

＜正＞ Aim: To investigate the preventive effect of autoantigen insulin given subcuta-neously on IDDM murine model and the influence on the phenotype and function of dendritic cell （DC） and CD4 + CD25 + regulatory T cells. Methods: The IDDM model was established by injection of multiple low dose of streptozotocin （STZ） 40 mg. kg - 1 intraperitoneally for 5 days in Bab1/c mice. The bovine insulin（100Mg） in IFA was given subcutaneously weekly for 4 weeks. The blood glucose was examined weekly. Pancreas tissues were taken for histopathologic examination. DC precursors from bone marrow and lymphocytes from spleen were isolated. The phenotype of DC and CD4+ CD25+ regulatory T cells were analyzed by FACS. T cell stimulating activity by DC was determined by allo-MLR. Results: The blood glucose in mice given insulin was well controlled, the amount of DC with CD11c was increased, expression of CD86 and MHC -Ⅱ was low and the capacity of stimulating T cell proliferation by DC was lower than those from the normal mice but higher than which from model mice, and the ratio of CD4 + CD25+ T cells were significantly enhanced. Conclusion: Subcutaneous administration of insulin can confer protection to mice from IDDM. The immune protection may be associated with establishing immune tolerance by improving the function of abnormal DC and promoting the production of CD4 + CD25 + T cells in vivo.

开发多活性位点绿色高效絮凝剂对构建低絮凝剂用量的高效固液分离过程、实现选矿废水高效处理与循环回用具有重要意义.本文为考察天然阳离子型线性高分子壳聚糖接枝阳离子型聚丙烯酰胺（Chi-g-CPAM）的絮凝性能，改变引发剂质量分数将壳聚糖、丙烯酰胺和二甲基二烯丙基氯化铵通过紫外引发水溶液聚合法进行接枝共聚，合成了分子结构不同的Chi-g-CPAM，使用石英晶体微天平（QCM-D）研究了其在SiO2芯片表面的吸附行为和后继原位絮凝高岭土的动力学，分析了絮体结构变化；并采用动力学方程拟合以揭示絮凝机理；最后进行了絮凝剂沉降性能试验.结果表明，长支链可增强絮凝剂对高岭土的架桥网捕作用，加快沉降；接枝率越高则有助于降低上清液浊度.引发剂质量分数为0.10%所合成的Chi-g-CPAM支链相对多而长，在SiO2芯片表面平衡吸附量最大，为（–11.68±0.40） Hz，吸附的第Ⅰ、Ⅱ阶段K值分别为0.1814和0.5054，吸附构象趋于向外伸展，后继所絮凝高岭土量少且絮体结构疏松，架桥、网捕和电中和作用协同使其在沉降试验中表现的沉降速率最大(12.18 m·h–1)，上清液浊度最低（13 NTU）.支链多而长的Chi-g-CPAM絮凝高岭土的过程复杂，准一级、准二级动力学和Elovich方程对其拟合效果均较好.引发剂质量分数为0.15%和0.05%时，对应所合成支链多而短、支链少而短的Chi-gCPAM在SiO2表面呈扁平的“列车式”吸附构象，架桥和网捕能力低，絮凝沉降性能差.多活性官能团絮凝剂的分子结构影响其在矿物表面的吸附构象，是决定其絮凝性能的关键因素之一.本研究对选矿大分子药剂的分子结构设计具有重要意义.
