A group of students from the Autonomous University of Querétaro (UAQ) designed a coating of stone surfaces from modified titanium nanoparticles.
The product "Nano TiO2" acts through a photocatalytic process, and was considered innovative and at the same time sustainable, because it cleans and prevents dirt from adhering to surfaces, while eliminating bacteria and purifying the air.
The UAQ students said that the application of "Nano TiO2" would be optimal in bridges, which become black over time, or in hospitals, since it kills bacteria, or in companies and homes where there is a large influx of carbon demonoxide, as it also purifies the air that comes into contact with the treated surface.
With this development, the students Ana Eloísa García de Gortari and Arlen Aurora Euan Martínez achieved second place in the Bi-National Sustainability Innovation Challenge that promotes the participation of the business sector between the United States and Mexico. This work was developed by the students based on research carried out by Karen Esquivel Escalante, research professor at the Faculty of Engineering of the UAQ.
