Scanning electrochemical cell microscopy(SECCM)is increasingly applied to determine the intrinsic catalytic activity of single electrocatalyst *** is especially feasible if the catalyst nanoparticles are large enough that they can be found and counted in post-SECCM scanning electron microscopy ***,this becomes impossible for very small nanoparticles and hence,a catalytic current measured in one landing zone of the SECCM droplet cannot be correlated to the exact number of catalyst *** show,that by introducing a ruler method employing a carbon nanoelectrode decorated with a countable number of the same catalyst particles from which the catalytic activity can be determined,the activity determined using SECCM from many spots can be converted in the intrinsic catalytic activity of a certain number of catalyst nanoparticles.

作者： JOACHIM quast Leibniz-centre for Agricultural Landscape Research Institute of Landscape D-15374 Müncheberg Germany

In floodplains of large rivers, more than eighty percent of the potentially inundated areas are developed for agricultural use and settlement purposes by diking and cultivation measures. The fertile soils of the polders represent ten percent of the agricultural lands in Germany. At its time, this agrarian potential justified the high societal input for diking, flood diversion, and drainage. The 80 000 hm2 large Oderbruch polder is deemed an example of prospering agrarian regions since 300 years ago and today it is part of the national cultural heritage. Numerous levee breaches and flood damages brought about increased efforts on levee construction and drainage. With growing technical facilities, drainage and the utilization of remaining wetland sites became the favoured target towards the development of highly productive man-made landscapes.

目的应用核磁共振成像(MRI)技术,观察蕲蛇酶(Acutobin)对高血糖大鼠脑损伤体积和灌注不足的影响。方法在高血糖大鼠右脑中动脉阻塞/再灌注(MCAO/R)的动物模型上,在MCAO60min和再灌注后24h各静注***-1体重蕲蛇酶1次,在MCAO/R前和后,连续检测记录多断层扩散加权成像(multslice diffusion weighted imaging,DWI)和单一断层动态快速注射轨迹梯度回波成像(single slice dynamic bolus tracking gradien echo imaging,GE)。结果蕲蛇酶治疗组DWI所检测的损伤体积,在再灌注后明显减少(P<0.05),右脑半球脑血流残留量(residual CBF)明显增多,动物死亡率明显降低。结论蕲蛇酶能改善高血糖大鼠MCAO/R模型脑组织的灌流,减少梗塞面积,降低死亡率。
