| 1 | 轮藻假根中的平衡石在回转器水平回转时的运动(英文)显示文摘利用回转器重现了在TEXUS火箭抛物线飞行的微重力实验中轮藻假根内平衡石向假根基部方向的运动。在快速回转器上回转15 min时,假根中的平衡石复合体中心离假根顶端的距离比在原来沿重力方向生长的假根中的距离增加了60%。细胞松弛素D的实验证实平衡石的这种运动是和肌动蛋白丝相关,而且在重力场中作用于平衡石的向基力也是肌动蛋白丝产生的。因此回转器和细胞松弛素D的实验证实了在地球上,平衡石的位置取决于作用方向相反的重力和肌动蛋白丝作用力的动态平衡的假说。然后在快速回转器上,平衡石中心在一个新的位置上维持了30 min左右的稳定,也就是出现了一个新的动态平衡状态。这一新的状态是在原先的向着假根顶端的重力和向着假根基部的肌动蛋白丝作用力的平衡在回转器上被打破后再经约有15 min时达到的。更进一步的快速回转器实验还展示了可能因平衡石位置的这一变化而启动的肌动蛋白丝的再组织和由此产生的平衡石向假根顶端方向再转运的过程。快速和慢速回转器实验在这里的结果有差异,推测是和回转器上颗粒的振幅随回转器转速的增加而减小有关。加之,轮藻假根的单细胞性质,因此在假根处于回转轴上时,快速回转器是更适合这项模拟失重的研究。总之,在失重条件下平衡石和肌动蛋白丝的关系是可以利用回转器来研究的。 | 蔡伟明 Markus Braun Andreas Sievers | 1997 | 实验生物学报1997，30，2： | 4 |

| 3 | Characterization of different plasma-treated cobalt oxide catalysts for oxygen reduction reaction in alkaline media显示文摘Plasma-synthesized cobalt oxide supported on carbon has been analyzed for its use for electrocatalytic oxygen reduction reaction(ORR) in alkaline anion exchange membrane fuel cells(AEMFC). This work presents the ORR activity in 0.1 mol L^(-1) KOH and 0.1 mol L^(-1) K_2CO_3at25 °C. Cyclic voltammetry(CV) was used to determine the potentials at which the ORR occurs and to evaluate the stability of catalyst. Moreover, a rotating ring-disk electrode(RRDE) was used to investigate the activity of the catalysts and the formation of the by-product hydroperoxide anion(HO2-) as well as to identify the preferred pathway of the ORR. Calculated kinetic parameters for the ORR for the cobalt catalysts are shown in this work together with a comparison to a commercial platinum catalyst. However, the cobalt oxide produced more by-products which could lead to damage of the membrane in a fuel cell through a radical attack of the polymer backbone. | Lisa M.Uhlig Gustav Sievers Volker Brüser Alexander Dyck Gunther Wittstock | 2016 | Science Bulletin2016，61，8： | 2 |
