Research on catalysis of sodium-metallochlorophylls in Ni/MH battery

The effects of sodium-metallochlorophylls including sodium-iron chlorophyllin, sodium-copper chlorophyllin and sodium-magnesium chlorophyllin on performance of Ni/MH battery were investigated. The results show that sodium-iron chlorophyllin can effectively activate the gases produced during charge in Ni/MH battery, therefore reducing the reduction potential of oxygen and the oxidation potential of hydrogen, and the increased speed of inner pressure of battery is decreased significantly. With the aid of DMol3 software, the activation process of oxygen and hydrogen by sodiummetallochlorophylls was simulated and analyzed. It was found that the catalysis behavior is in agreement with the experimental results, and the activation process also gets a reasonable explanation from the calculated results.     

从氢氧化氢(HOH)之角度者水的性质

水(H2O)是我们非常熟悉的物质,人们已经习惯于水叫做"氧化氢",实际上水也可以叫做"互氧化氢",并且把水理解为"氢氧化氢"对学习中学化学很有帮助,笔者根据水分子的结构时水在参与化学反应中的断键进行了一定的论述:一,"氢氧化氢"与相似相溶原理:二、"氢氧化氢"的异裂与均裂,三、"氢氧化氢"的异裂与离子型反应,四、"氢氧化氢"的均裂与反应.     

废旧干电池污染液对泥鳅超氧化物歧化酶和过氧化氢酶活性的影响

将泥鳅暴露于不同浓度的废旧干电池污染液中,于48 h、72 h测定其超氧化物歧化酶(SOD)及过氧化氢酶(CAT)的活性,结果显示低浓度、短时间内SOD、CAT活性被诱导,随着废旧干电池污染液浓度的增大和暴露时间的延长,酶活性被抑制.因此SOD、CAT可作为生物标志物来监测水生态系统的污染.
