Superhidrofobicidad: Un balance Entre Fuerzas (Superhydrophobicity: A Balance Between Forces)
Teaching Materials | 25 Apr 2020 | Contributor(s):: Nano-Link Center for Nanotechnology Education, Thomas Deits, Kristi Jean, Deb Newberry (editor), Rodfal A. Rodríguez (editor), María T. Rivera (editor)
Este módulo demuestra y provee a los estudiantes un entendimiento de las fuerzas presentes en las interacciones hidrofóbicas e hidrofílicas. El balance entre las fuerzas cohesivas y adhesivas tiene como resultado una gota de agua casi esférica sobre una superficie,...

Polímeros Entrecruzados o Reticulados (Cross-Link Polymer)
Teaching Materials | 22 Apr 2020 | 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...

Superhydrophobicity: A Balance Between Forces
Teaching Materials | 16 Apr 2020 | Contributor(s):: Nano-Link Center for Nanotechnology Education, Thomas Deits, Kristi Jean, Deb Newberry
This module demonstrates and gives students an understanding of the forces behind hydrophobic and hydrophilic interactions. The balance between cohesive and adhesive forces results in an almost spherical drop of water standing on a surface, such as a lotus leaf. This effect is called...

Surface Area to Volume Ratio
Teaching Materials | 16 Apr 2020 | 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...
