22 Apr 2020 | Teaching Materials | Contributor(s): Nano-Link Center for Nanotechnology Education, Deb Newberry, Billie Copley, Laura Arndt (editor), jim Marti (editor), Rodfal A. Rodríguez (editor), María T. Rivera (editor)
Este módulo les permite a los estudiantes investigar las fuerzas e interacciones a escala molecular mezclando diferentes líquidos con un polímero entrecruzado/reticulado. Este polímero (poliacrilato de sodio) comparte similitudes estructurales con la celulosa y...
Surface Area to Volume Ratio
16 Apr 2020 | Teaching Materials | Contributor(s): Nano-Link Center for Nanotechnology Education, Deb Newberry, Billie Copley
This simple activity conveys one of the most profound aspects of Nanoscience – that for a given volume of material the total surface area increases non-linearly as the volume is divided into smaller and smaller pieces. This concept is being applied to creating better batteries and...
Cross-Link Polymer
16 Apr 2020 | Teaching Materials | Contributor(s): Nano-Link Center for Nanotechnology Education, Deb Newberry, Billie Copley, Jim Marti (editor), Laura Arndt (editor)
This module allows students to investigate forces and interactions at the molecular scale by mixing different liquids with a cross-linked polymer. The polymer (sodium polyacrylate) is similar to the structure found in cellulose and collagen. The interactions are dependent upon the charge...
Razón área Superficial a Volumen (Surface Area to Volume Ratio)
25 Apr 2020 | Teaching Materials | Contributor(s): Nano-Link Center for Nanotechnology Education, Deb Newberry, Billie Copley, Rodfal A. Rodríguez (editor), María T. Rivera (editor)
Este módulo consta de una actividad simple que trabaja uno de los aspectos más profundos de la nanociencia: que, para un volumen dado de material, el área superficial total aumenta de forma no lineal a medida que el volumen se divide en partes cada vez más...
