DEVICE FOR PRODUCING NANOPARTICLES FROM GASES AND VAPORS OF LIQUIDS AT ULTRA-LOW TEMPERATURES Russian patent published in 2021 - IPC B01J13/02 B82Y40/00 F04B15/08 

FIELD: nanotechnology.

SUBSTANCE: invention relates to the field of nanotechnology, namely, the proposed device makes it possible to obtain small particles (nanoparticles) from materials that exist at room temperatures in the form of gases or vapors. The device for producing nanoparticles from materials existing at room temperature in the form of gases and vapors of liquids includes a helium cryostat with windows, a condensation tube, an ampoule for collecting nanoparticles. The ampoule for collecting nanoparticles contains superfluid helium. The level of superfluid helium in the ampoule is maintained by a cryopump through an additional supply tube. The condensation tube is made with the possibility of supplying an impurity-helium mixture.

EFFECT: invention makes it possible to avoid losses of the condensed flow and increase the nanoparticle collection time.
