A NEW METHOD TO TRANSPORT GAS MOLECULES

摘要：

In this report,ultrasound based molecular transport from gas onto a solid material surface is demonstrated,and the molecular transport is confirmed by the detection based on a gas sensor.In the experiments,a standing wave ultrasonic field of 46.25 kHz was used to transport CO gas molecules onto the surface of a SnO2 sensing layer.The experimental results show that the CO molecules can be transported onto the sensing layer when the ultrasound exists in the vicinity of the sensing layer,and the molecular transport can be enhanced by making the ultrasonic field resonant or stronger.
