Fast Reactions

Fast reactions occurring in times shorter than the time needed to mix reactants pose a unique challenge for investigation. In a liquid-phase continuous-flow system, reactants A and B are swiftly pushed into the mixing chamber, where mixing occurs within 1 ms. The reaction mixture then flows through an observation tube, and one measures light absorption to determine species concentrations at various points of the tube. This method is most appropriate when relatively large volumes of reactants...

概括

研究人员在反应扩散介质中发现了一种新型的嵌合体状态,即自我组织的目标波嵌合体. 这一发现表明,同步波可以从异步振荡器中出现,这挑战了现有的关于嵌合体状态的理论.
