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...
Making a Liquid Crystal Thermometer
09 Jan 2017 | | Contributor(s):: Rano Sidhu
Liquid crystals are matter that has properties between those of a liquid and a solid. Liquid crystals may flow like a liquid but have crystals like a solid.colors of the objects are Color is the outcome of various light properties: absorption, refraction, or reflection. In the case of liquid...
Seeing Nano: Using Scanning Electron Microscopy (SEM) to View Nano-size Objects
02 Dec 2016 | | Contributor(s):: Samantha Andrews
Nano-size objects are smaller than the wavelength of light and because of this they cannot be viewed with a light microscope. Special tools are needed to see nanoscale objects, one of which is the scanning electron microscope. This activity will have students explore the types of images...
Synthesis and Stability of Silver Nanoparticles
01 Dec 2016 | | Contributor(s):: Brandi Childress
The purpose of this experiment is to conduct synthesis of silver nanoplates and explore their shape stability that affects optical property (referred to as localized surface plasmon resonance (LSPR). Students will learn about the differences in physical properties and behavior at the...
General Chemistry. Nanoscience and Computational Chemistry Modules
General Chemistry courses are taught at every college and university, and usually the goal is to cover the field of chemistry broadly over the course of an academic year. The topics included in...
