I work in the Departmen of Physics of Materials at Centro de Investigaciones en Materiales Avanzados S. C. CIMAV Chihuahua. I learned about OpenWetWare from I RECOGNIZE ONE OF MY CO-WORKERS ON THIS WEB SITE, and I've joined because I would like to share my research. I am interesting in material science and nanotechnology.
