We fully utilized the characteristics of the deficient electron structure ( carbon sp3 and boron ) and easy oxidation introducing - oh on bdd electrode surface to preparation of biosensors , which were used to investigate the electrochemistry of biological molecules and be rapid , sensitive 利用bdd电极的表面缺电子结构( sp3杂化碳和掺杂的硼)和易于氧化引入- oh的特点,在氧化或未氧化的bdd电极表面修饰化学/生物物质制成化学/生物传感器,研究生物分子在电极表面的电化学特性,并实现对生物分子的准确、快速、灵敏、简便测定。
The fitness of four negative electrode materials such as al , fe , zn , cd , and of six membranes materials : microfiber glass mat separator , polyethylene , polypropylene , polyvinyl chloride , vinylon , soapnated cellulose acetate , and of four current collects : carbon fiber ; nickel foam ; nickel foam sthongthened by iron wire net , punched silver grid in the super - iron alkaline batteries was comparatively studied . the influence of two storaged method ( with and without electrolyte ) and two impurities ( zno , fe ( oh ) 3 ) to the experiment cell ' s self - discharge nature was also comparatively studied . at last , the nature of discharge . structure and electrochemistry of experimental cell with k2feo4 as cathode active material prepared by three different methods : high temperature reaction , hypochlorite oxidizing and electrolysis , was comparative ly studied . we can conclude : i ) the open - circuit potential and the flat of work potential and the percent of capacity of k2feo4 till 1 . 0v during the discharge at constant load of experimental cells decreased by the order of al / k2feo4 , zn / k2feo4 , cd / k2feo4 , fe / k2feo4 . as for the nature of charge - discharge cycle , cd / k2feo4 fe / k2feo4 zn / k2feo4 . in water solute electrolyte , although al / k2feo4 can n ' t be used as storage battery , it have great potential as primary cell or storage cell from the aspect of its discharge capacity . discharge power 采用组装实验电池、 x -射线衍射( xrd )和循环伏安( cv )的方法，从实验电池的放电特性、充放电循环特性、自放电特性，不同高铁酸盐的结构特性和电化学特性几个方面，对4种金属负极材料( al 、 fe 、 zn 、 cd ) 、 6种隔膜材料(复合玻璃纤维、幅射接枝聚乙烯、改性聚丙烯、聚氯乙烯、维尼纶无纺布、皂化再生纤维素) 、 4种集流体材料(泡沫镍、以铁网为加强层的泡沫镍、切拉银网、炭纤维编织网)在碱性高铁电池中的适用性进行了比较研究；对2种杂质组分( zno 、 fe ( oh ) _ 3 )和2类不同贮存方式(干、湿)对实验电池自放电特性的影响进行了比较研究；对3种方法(高温固相反应、次氯酸盐氧化、直流电解)所制k _ 2feo _ 4的实验电池的放电特性、结构特性和电化学性能进行了比较研究。
