Abstract
Gas flow control is essential in multifarious fields, such as chemical engineering, environmental governance, and biomedical science. More precise regulation, especially tunable gas flow rates, will spark further applications in smart valves, microreactors, and drug delivery. Here, we propose a crystallization-induced liquid gate (CILG) comprising a supersaturated gating liquid confined within a solid framework capable of tunable gas flow rates under steady-state pressure in a simple and compact manner. When ultrasound is employed to stimulate the crystallization, the CILG exhibits different gas transport behaviors due to the adjustable pore sizes modulated by crystal morphologies under varied ultrasound intensities. Additionally, the exothermic crystallization process allows CILG with variable gas permeability to be observable via infrared imaging. Moreover, we demonstrate the potential applications of CILG in infrared-monitored flow-regulating valves and gas-involved chemical reactors.
期刊介绍:
The Journal of Physical Chemistry (JPC) Letters is devoted to reporting new and original experimental and theoretical basic research of interest to physical chemists, biophysical chemists, chemical physicists, physicists, material scientists, and engineers. An important criterion for acceptance is that the paper reports a significant scientific advance and/or physical insight such that rapid publication is essential. Two issues of JPC Letters are published each month.
