A novel polyoxovanadate-based MOFs microsphere,[Ni(phen)V2O7]H2O(phen = 1,10-phenanthroline),constructed from 3-D discrete nano-sheets has been prepared and characterized by XRD,FT-IR,SEM and TEM.Electrochemical properties as supercapacitor of the as-prepared sample,such as CV,EIS,GCD and the cycle life test have also been studied.The as-prepared MOF(V,Ni)showed a high specific capacitance of 178.09 F·g-1 at 1 A·g-1 as well as good cycling stability and coulombic efficiency.This work proved that the novel MOFs based on polyoxovanadate hybrid material may serve as a promising electrode material for high-performance supercapacitor.

为研究河流入海口处盐度周期变化时铝牺牲阳极对钢结构的保护效果,测试对比了盐度固定与盐度循环条件下Q235钢有无阳极保护时的腐蚀失重和电位变化、铝牺牲阳极的电流效率。结果表明盐度循环会造成Q235钢的严重腐蚀,盐度差越大腐蚀越严重,甚至可能超过天然海水的腐蚀程度;在盐度循环条件下铝牺牲阳极对Q235钢具有良好的保护效果,但与稳定的盐度相比,阳极的消耗量增加、电流效率降低;在稳定的低盐度条件(0.5%)下,虽然铝牺牲阳极的电流效率较高,被保护的Q235钢电位足够负,但是保护效果不理想。本文通过Q235钢腐蚀失

细菌源3-羟基脂肪酸(C10-C18)作为环境变化指示指标具有良好的应用前景,但相关研究还很不系统,在海洋环境中的应用刚刚起步。3-羟基脂肪酸主要用于环境中pH和温度的重建,通过其支链比(异构和反异构3-羟基脂肪酸之和/正构3-羟基脂肪酸之和)与pH的显著正相关关系反演环境中的pH,通过其C15和C17同系物的反异构/正构比(RAN15和RAN17)与大气年均温的显著负相关关系反演环境中的温度,相比基于甘油二烷基甘油四醚类化合物或其他生物标志物的环境代用指标具有明显的优势。然而,陆地生态系统中基于3-羟基

沙菜属(Hypnea)是卡拉胶生产的重要经济栽培物种,但该属具有复杂的命名史和物种分类难题,其广泛的地理分布、高度的遗传变异以及较强的表型可塑性,存在许多同物异名和形态趋同的现象,导致其物种鉴定中出现了一系列的争议。因此,本文尝试总结分析沙菜属分类中存在的问题,以及涉及“物种”定义的初步探讨,特别是基因树与物种树的关联性,以期为解决该属分类学问题提供一定的参考思路。
海上风电场建设期风机打桩会产生高强度的水下噪声,研究水下冲击打桩噪声的监测方法、特性分析及对海洋生物的影响是非常重要的。采用自容式水下声音记录仪,多点同步测量了福建省兴化湾海上风电场二期工程建设期单次完整的水下冲击打桩噪声,从时频域特性进行了分析,并利用最小二乘法拟合得到了打桩声源级和声暴露级。结果表明:水下冲击打桩噪声是典型的低频、高强度的脉冲信号,单个脉冲持续时间约90~100 ms,峰值声源级约209.4±2 dB,声暴露级约197.7±2 dB;主要能量分布在50 Hz~1 kHz频段,750 m
