Effect of gold nanoparticles on chemical oscillators A Science Experiments on pH Levels Sciencing

In order to elucidate the effect of the Au nanoparticles on the reaction dynamics of the pH oscillators we also performed simulations with seven independent reaction rate constants k in Fig 3 The change in the magnitude of each k exhibited a characteristic feature in the oscillation dynamicsScience experiments on pH levels help investigators determine the pH level of a given material and how that level might affect the environment These experiments can illustrate important processes such as the effect of acid rain on bodies of water
