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...
[Illinois] Interphase Chemical Mapping Of Carbon Fiber-epoxy Composites By Afm-ir Spectroscopy
13 Apr 2017 | Contributor(s):: Chris Montgomery
The properties and performance of carbon fiber reinforced polymer matrix composites are highly influenced by the chemical interactions of the fiber/matrix interface region. Many researchers have hypothesized that the presence of carbon fibers in epoxy causes a chemical gradient to form around...
Silver Nanoparticle Synthesis, Spectroscopy, and Bacterial Growth
11 Jan 2017 | | Contributor(s):: Pennsylvania State University
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...

Exciton Dynamics Lab for Light-Harvesting Complexes (GPU-HEOM)
18 Dec 2012 | | Contributor(s):: Christoph Kreisbeck, Tobias Kramer
Non-Markovian calculation of absorption spectra, 2d echo-spectra, coherences and polulation dynamics for light-harvesting complexes.
Excited State Spectroscopy of a Quantum Dot Molecule
16 Dec 2011 | | Contributor(s):: Muhammad Usman
Atomistic electronic structure calculations are performed to study the coherent inter-dot couplings of the electronic states in a single InGaAs quantum dot molecule. The experimentally observed excitonic spectrum by Krenner et al (Phys. Rev. Lett. 94 057402, 2005) is quantitatively reproduced,...

Nanoscale Spectroscopy and Plasmonics in Infrared
09 Mar 2012 | | Contributor(s):: Mikhail Belkin
In this talk, I will present the results of two of our research projects. I will start with a simple technique for nanoscale mid-infrared spectroscopy that we have developed recently. Subwavelength resolution is achieved by detecting optical absorption through measuring local photothermal...

Large-scale first principles configuration interaction calculations of optical absorption in boron clusters
07 Mar 2012 | | Contributor(s):: Ravindra L Shinde
We have performed systematic large-scale all-electron correlated calculations on boron clustersBn (n=2–5), to study their linear optical absorption spectra. Several possible isomers of each clus-ter were considered, and their geometries were optimized at the coupled-cluster singles doubles(CCSD)...
