This document, created by Pennsylvania State University and hosted by the Nanotechnology Applications and Career Knowledge Network, serves as a guide for a laboratory activity where students "synthesize colloidal gold nanoparticles from solution-phase precursors" and "use UV-vis spectrophotometry to measure changes in the color of the resulting colloidal suspension as an electrolyte is added." The lab guide includes objectives, an introduction to colloids, step-by-step directions to the lab activity itself, and post-lab questions to test student comprehension. In order to access and download this material, users must complete a free registration.

This webinar is provided by Internet Scout Research Group and was presented by Rachael Bower and Kendra Bouda of ATE Central. The webinar introduces the ATE Central archive, the NSF archiving requirement for Advanced Technological Education (ATE) projects and centers, as well as discusses the importance of archiving for both individual ATE projects and centers and the ATE community as a whole. In addition, tools and services to facilitate archiving with ATE Central are discussed, such as an archiving checklist, an archiving worksheet, and ATE Central's online archiving submission form. 

The webinar recording runs 58:36 minutes in length.
