Abstract:
1. A system for making nanoparticles, the system compnsing: a first cathode including a first metal tube, the first metal tube including a first end and a second end; a first anode including a second metal tube, the second metal tube including a third end and a fourth end; a first container including a first gas inlet, the first end and the third end being located inside the first container; wherein: the first end and the third end are separated by a first gap; the first metal tube is configured to allow a first gas to flow from the second end to the first end; the first container is configured to allow a second gas to flow from the first gas inlet into the second metal tube through at least a first part of the first gap; the first cathode and the first anode are configured to generate a first plasma discharge at a first pressure equal to or higher than one atmospheric pressure; the first plasma discharge is capable of being used for making a first plurality of nanoparticles.
