METHOD OF PRODUCING NANOFLUID USING LASER ABLATION, CORRESPONDING NANOFLUID AND LASER ABLATION SYSTEM FOR PRODUCING NANOFLUIDS Russian patent published in 2025 - IPC B01J13/02 B23K26/122 

FIELD: chemistry; performing operations.

SUBSTANCE: group of inventions relates to a novel process for single-step large-scale production of various nanofluids in a modified version of laser ablation in an open atmosphere. Method of producing a nanofluid involves laser ablation of a target on the surface of which a liquid flows. Fluid continuously flows over target surface at preset rate to maintain preset thickness of said fluid. Method is carried out in an open atmosphere using a target selected from platinum group metals, copper, aluminium or their oxides, nitrides or carbides. Fluid is heated to preset temperature to optimize viscosity for uniform flow. Also disclosed is a nanofluid for improving thermal properties and heat transfer characteristics of fluids, made in accordance with the method, and a laser ablation system for producing nanofluids.

EFFECT: group of inventions provides a single-step large-scale production of nanoparticles from metal, oxide, carbide and nitride targets, which can be made in the form of nanofluids, in various liquids, such as oils, H₂O, ethylene glycol (EG), and these nanofluids have high thermal conductivity.
