  7. Cross-Link Polymer

    16 Apr 2020 | | 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...

  8. Nanoparticles and Sunscreen

    16 Apr 2020 | | Contributor(s):: Nano-Link Center for Nanotechnology Education, Thomas Deits, Jim Marti (editor), Christopher Kumm

    In this module, students are introduced to the function of sunscreen and learn how nanoparticles can be used to protect people from ultraviolet radiation.  They use photochromic paper as a UV sensor, place samples of different types of sunscreen over this UV sensor, expose their samples to...

  9. Ring Polymers

    16 Apr 2020 | | Contributor(s):: Nano-Link Center for Nanotechnology Education, Deb Newberry, NISE Net

    This module is a variation on the “Cross-Linked Polymers” activity, and presents much of the same background on polymer structure and properties.  This version uses a form of sodium polyacrylate, the water-absorbing polymer often used in diapers, that has a different atomic...

  10. Scientific Method

    16 Apr 2020 | | Contributor(s):: Nano-Link Center for Nanotechnology Education, Thomas Deits, Deb Newberry (editor)

    In this module, students will use cellophane “fortune telling” fish to walk through the scientific method. The students learn and practice the scientific method by proposing, testing and observing what happens with their "fish". Students will test various...

  11. Superhydrophobicity: A Balance Between Forces

    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...

  12. Surface Area to Volume Ratio

    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...
