Invisible Sunblock

"Invisible Sunblock" is a hands-on activity exploring how nano-scale particles are used in mineral sunblocks to increase their transparency. Visitors compare nano and non-nano sunblocks to a visual representation of the effect of particle size on visibility.

Changing Colors

Changing Colors is an interactive exhibit that shows how some high-tech nanomaterials mimic natural phenomena. Super-small, light-reflecting structures—instead of pigments—on the wings of some butterflies create intense, iridescent colors. Nanoscientists have replicated this effect with layered, super-thin films. Watch the colors change on butterfly wings and thin-film slides as you move them beneath a light source, and discover how nanoscale structures can manipulate light and create color. Butterfly specimens deteriorate with heavy use, and may need to be replaced periodically.

Online Brown-Bag: The Science Behind NanoDays 2013 Activities - Part Two: Laddering Activities Around Polymers and Light at the Nanoscale (Recorded)

This is a recording of a NISE Network online brown-bag conversation held in 2013. This brown-bag conversation focused on the science behind NISE activities related to polymers or light at the nanoscale. The following activities were discussed:

• Exploring Fabrication - Gummy Capsules • Exploring Materials - Hydrogel • Exploring Structures - Butterfly • Exploring Materials - Thin Films • Exploring Properties - Invisibility

Presented by: Rashmi Nanjundaswamy and Lizzie Hager-Barnard, Lawrence Hall of Science, Univeristy of California, Berkely
