Measuring temperature effects on nanobubble nucleation via a solid-state nanopore

Abstract

In this study, we design a 〖SiN〗_X solid-state nanopore to detect the temperature effect on hydrogen nanobubble formation. Here, we integrated the temperature controller with the high sensitive nanopore. As the temperature decreases from 25 ℃ to 5 ℃, the occurance for the nanobubble nucleation inside a 12.3 nm 〖SiN〗_X nanopore confined space decreases from 102 s^(-1) to 23 s^(-1), and the life-time of nanobubbles increases from 1.16 ms to 4.78 ms, respectively. The results further gives the activation energy for nanobubble nucleation which is 8.1 × 10-20 J with a 12.3 nm 〖SiN〗_X nanopore. Our method provides an efficient analytical tool for analyzing the temperature-dependent nanobubble nucleation, which further benefits to the fundamental understanding of nanobubbles.
