Position Description: Two postdoctoral associate positions in the area of advanced synthesis and nano/micro-scale characterization of nanoparticles are available at Rice University. Various techniques will be applied to synthesize and self-assemble size- and shape-controlled silicate nanoparticles followed by nano- and micro-characterizations including a myriad of probes such as electron microscopies (TEM, XRD, SEM, AFM), ICP, XPS, NMR, porosimetry, dynamic mechanical analysis, nanoindentation, etc.

I have attached a copy of my McMat07 talk below.  The talk is about a modified mechanical threshold stress (Follansbee-Kocks) model that can be used for strain rates > 1000 /s and high homologous temperatures.  In the model, the pressure dependence of the flow stress arises from the pressure dependence of the shear modulus.  Even after using the most accurate models for the shear modulus (and the melting temperature) we find that the pressure sensitivity of the flow stress is underestimated by our model (by quite a bit).
