Mystery Molecules: Identifying Materials with Nanoscale Characterization Tools
18 Mar 2020 | | Contributor(s):: Maude Cuchiara, NNCI Nano
In this lesson plan, students will be given several similar looking materials and asked to identify them by observing them at the macro and micro-scale. They will then be exposed to different analytical tools and describe how they can be used to explore materials at the nanoscale. ...
Silver Nanoparticle Synthesis, Spectroscopy, and Bacterial Growth
11 Jan 2017 | | Contributor(s):: Pennsylvania State University, NNCI Nano
Students will learn about the differences in physical propoerties at the nanoscale as compared to the same materials at the macroscale. The students will demonstrate the appropriate use of a spectrophotometer and will convert between different units of measurement. This unit assists students in...
Synthesis and Analysis of Silver/Gold Nanoparticles
01 May 2017 | | Contributor(s):: Shelby Hatch, George C. Schatz
This lab provides instructions for the synthesis of nanoscale silver colloidal particles along with questions to guide student thinking regarding the molecular-scale interactions between acids, bases, salts and sugar with the silver particles.A UV-Vis spectrophotometer (300-800 nm) is used to...
