Molecular Modeling and Electronic Structure Calculations
01 May 2017 | Contributor(s): George C. Schatz, Baudilio Tejerina, Shelby Hatch, Jennifer Roden
This is a purely computational project that is concerned with using the nanoHUB tool QC-Lab to create and optimize molecules, and to study their spectroscopic and structural properties. The molecules studied are generally small molecules of interest to atmospheric chemistry, however the tool can...
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...
Optical and Thermodynamic properties of noble metal nanoparticles. Effect of chemical functionalization.
06 May 2009 | Contributor(s): Baudilio Tejerina, George C. Schatz
This laboratory is intended to introduce the student to the use of semiempirical electronic structure methods. In particular, the semiempirical methods will be applied to the study of metallic clusters and the interaction of the clusters with molecules such as pyridine. The reactivity of the...
Theoretical Analysis of Gold Nanoparticles
06 May 2009 | Contributor(s): Jon Camden, George C. Schatz, Baudilio Tejerina
All physical and chemical properties are size dependent, and the properties of materials on the nanosize scale have important consequences in wide ranging fields. Exploiting nanoscale behavior will eventually lead scientists to develop devices that can selectively attack diseased cells, increase...
