Starting from an example of how to extinguish a fire, this article illustrates how chemical dynamics plays a role in our life. It also introduces what is chemical dynamics and the contribution of Dutch chemist Jacobus H. van't Hoff to chemical dynamics. The horse racing analogy is used to illustrate how the amount of reactants, energy, catalysts and other factors affect the chemical reaction rate.  相似文献

根据5'核酸外切酶与底物间相互作用的特点,设计开发了对其具有高选择性、高灵敏度的DNA荧光探针。该探针对5'外切酶的线性响应范围为0.005~0.1 U/m L,检测限为0.005 U/m L。方法可用于人血清样品中5'外切酶的一步快速测定,测得正常人血清中5'外切酶的含量为0.09±0.01 U/m L,回收率为100%±5%(n=3)。该研究为实时监测生物样品中5'核酸外切酶的含量变化提供了有力的工具,也将有助于深入研究核酸损伤的修复途径。  相似文献

This is a popular science article introducing the chemical knowledge contained in the search and use of colors. From the different aspects of architectural, textile dyeing and paints, three examples are chosen to reveal the chemical principles behind. Humanistic story and science interpretations are combined to reflect the close connection between chemistry and human life.  相似文献
