AFM training: Bruker Dimension Edge at IFUAP

Equipmen: AFM Bruker Dimension Edge 

Responsible research: Dr. Francisco Flores 

Day: 1

First training day on AFM Bruker Dimension Edge AFM at the Physics Institute of BUAP. This equipment will allow the measurement of topography properties like roughness and grain size. The researcher in charge explains too that it's possible to acquire electrical conductivity and work function from the surface of the films.

Alebrijes - Libro de Cecilia Reyes

Lectura corta, páginas 47-49. Excelente libro para disfrutar en compañía de tu ser querido, cuenta la historia del artesano cartonero Pedro Linares López inventor de los Alebrijes en México del siglo XX. Consíguelo aquí: https://amzn.to/34YcKNN
-- Un homenaje a la creación del artesano mexicano Pedro Linares López quien en un trance cercano a la muerte tuvo la visión de animales tenebrosos que no eran de este mundo y que más tarde, gracias a su imaginación y a la magia de sus manos, fue capaz de traer a la realidad. "Alebrijes alebrijes", escuchó que gritaban en su sueño.

Laboratory - Bismuth Sulfide thin films

Location: Physics Institute of BUAP, Puebla, Pue.  

Chemical deposition:  Bi2S3 Bismuth Sulfide

Supervisor: M.C Denisse Loeza 

Chemical deposition of bismuth sulfide from the master thesis work of M.C. Denisse Loeza. This work has the intention to develop new materials (semiconductors) for solar cells. Like the ternary compound Cu3BiS3, which posses potential properties as a p-type semiconductor for absorber layer on thin-film technology.
