“纳秒”电化学被用来研究声乳化的含水电解质和少量的庚烷的混合物。在恒电位条件下观察到微秒级的电流尖峰，这归因于庚烷液滴对电极表面的冲击。瞬态的极性被发现改变电极电位通过接受的电位的零电荷的电极/电解质系统的金和铂电极。一个可能的解释是建议和一个通用的方法来实验测量的固体电极的零电荷（pzc）的电位的影响。
"Nanosecond" electrochemistry is used to study acoustically emulsified mixtures of aqueous electrolyte and smaller quantities of heptane. Significant current spikes of microsecond duration are observed under potentiostatic conditions and attributed to the impacting of heptane droplets onto the electrode surface. The polarity of the transients is found to change as the electrode potential varies through the accepted potential of zero charge of the electrode/electrolyte system for both gold and platinum electrodes. A possible explanation is suggested and the implications for a generic approach to the experimental measurements of potentials of zero charge (pzc) of solid electrodes noted.
