  • White light emitting material and method of preparation and uses thereof
    Patent number: 10280366
    Abstract: The instant invention is related with new perimidine derivatives synthesized via direct condensation between naphthalene-1,8-diamine and itaconic or citraconic anhydrides at low temperature. The targeting itaco-perinone (IP) molecule formed via double low temperature cyclization has fluorescence properties emitting white light intensively. Besides, 9-methylene-8H-pyrrolo[1,2-a]perimidin-10(9H)-one is copolymerizable with several kind of organic monomer compounds via free radical mechanism maintaining the ability to emit white light even within the polymer film.
    Type: Grant
    Filed: June 21, 2016
    Date of Patent: May 7, 2019
    Assignees: Instituto Potosino DE Investigación Cientiffica y Technológica A.C., UNIVERSIDAD NACIONAL AUTONOMA de Mexico
    Inventors: Alejando Ricardo Femat Flores, David Rios Jara, Larissa Alexandrova, César Augusto Fernández Gijón, Guillermo Santana Rodriguez

  • Reinforced aluminum alloy and its process of manufacture
    Patent number: 7694713
    Abstract: The present invention relates to a process for hardening an aluminum-based matrix alloy by the dispersion of metallized graphite (MG) with copper and optionally zinc or boron by the agitation in liquid state. By this means, the impregnating of MG particles (reinforcing phase) is increased, facilitating the homogenous distribution in the aluminum-base matrix alloy. The mechanical properties of aluminum or aluminum-based are increased alloys by the process of hardening by dispersion, without affecting the density and electrical conductivity of the alloy.
