Title
(EN) 3D REDUCED GRAPHENE OXIDE/SIO 2 COMPOSITE FOR ICE NUCLEATION
(FR) COMPOSITE OXYDE DE GRAPHÈNE RÉDUIT 3D/SIO2 POUR LA NUCLÉATION DE LA GLACE
Abstract
(EN) The present invention provides for an ice-nucleating particle for cloud seeding and other applications, which can initiate ice nucleation at a temperature of –8°C. Further, the ice nucleation particle number increased continuously and rapidly with the reducing of temperature. The ice nucleating particle in the present invention is a nanostructured porous composite of 3-dimensional reduced graphene oxide and silica dioxide nanoparticles (PrGO-SN). The present invention also provides for a process for synthesizing the PrGO-SN.
(FR) La présente invention concerne une particule glaçogène pour l'ensemencement de nuages et d'autres applications, qui peut initier la nucléation de la glace à une température de -8 °C. En outre, le nombre de particules glaçogènes augmente en continu et rapidement avec la réduction de la température. La particule glaçogène de la présente invention est un composite poreux nanostructuré d'oxyde de graphène réduit tridimensionnel et de nanoparticules de dioxyde de silicium (PrGO-SN). L'invention concerne aussi un procédé de synthèse de PrGO-SN.
