Over the last decade, particle tracking microrheology has matured as a new tool for complex fluids research. The main advantages of microrheology over traditional macroscopic rheometry are: the required sample size is extremely small (~ 1 mL); local viscoelastic properties in a sample can be probed with high spatial resolution (~1-10 mm); and the sample is not disturbed by moving rheometer parts. I will present two examples of recent work in my group that highlight how these characteristics can be exploited to acquire unique information about t ....etc

One of the central objectives of multiscale materials modeling is to develop and apply simulation techniques to uncover atomic-level mechanisms without the significant limitations on system size and simulation time inherent to purely atomistic methods. In this context, I have made two contributions. I developed an interatomic potential finite element method (IPFEM) to study homogeneous dislocation nucleation by nano-indentation. The implementation of IPFEM facilitates simulations at length scales that are large compared to atomic dimensions, wh ....etc

Abstract

To analyze a new endodontic sealer material commercially known as Resilon and to describe in detail the experimental techniques employed that lead to the identification of the composite material.
Methods

An extensive structural, thermal, and physical characterization was used to identify a new endodontic sealer material using the following techniques: Fourier transform infrared (FTIR) spectroscopy, nuclear magnetic resonance (NMR) analysis, X-ray fluorescence spectrometry (XRF) technique, X-ray diffraction (XRD) measurement, th ....etc

Protein Characterization
Why do we analyse proteins?
• Proteins play crucial roles in nearly all biological processes. These many functions of proteins are a result of the folding of proteins into many distinct 3D structures.
• Protein analysis tries to explore how amino acid sequences specify the structure of proteins and how these proteins bind to substrates and other molecules to perform their functions.
• Protein analysis allows us to understand the function of the p ....etc

Isolation and Spectral Characterization of Chlorophyll-Protein Complexes of Chloroplast Thylakoid Membranes
Introduction
In the undergraduate biology laboratory, labs on photosynthesis ordinarily fall into a small
number of categories:
1. measurement of the overall process of photosynthesis by carbon dioxide uptake or
oxygen evolution
2. measurement of the Hill reaction (the light driven reduction of an exogenous dye with
electrons from water) in isolated chloroplasts
3. pigment analysis by thin-layer or paper chromatography
Ou ....etc

Although grinding is considered one of the more established manufacturing processes, it is still relatively poorly understood. In particular, the interaction of the wheel with the workpiece at times seems more like an art than a science. In this presentation, a 3-D topographic measurement approach which encompasses both the wheel and the workpiece will be presented. The topographic information obtained from the wheel will be applied to a model to predict the workpiece surface generated which will then be verified by experimentation. The prelimi ....etc
