Quantum Dot Research Week 6 Lab S117 Fall 2011
Overview • Post-Lab • Results of Affinity Chromatography • Pre-lab: Quantum Dot Research • Nanomaterials • Band gap theory • Synthetic strategy • The experiment
Affinity Chromatography • Trouble-shooting • Possible sources of error? • Possible solutions? • The question: What is the next step we can take to improve our experiment?
Quantum Dot Research nanomaterials
Nanomaterial Application • Drug delivery • Ultrafiltration • Catalysis • Energy storage/ utilization
Small Molecules and Bulk Materials From J. Chem. Ed. Vol 84 pp709-710
Synthetic Strategy • Control nanoparticle growth! • Time dependence • Emulsion • Colloidal suspension
The Experiment 1 2 3 4 http://mrsec.wisc.edu/Edetc/nanolab/CdSe/index.html
Some Key Points • Safety with toxic chemicals • Patience with the temperature • Temperature quenching • Safety first! (Practice transfers.) • Quickness second! • Time accuracy third!
