Viscoelastic Coalescence Of Thermotropic Liquid Crystalline Polymers: The Role Of Transient Rheology
(AIP Publishing, 2005-11-01)
The coalescence in air of two polymeric drops into a single drop (also referred to as sintering) was investigated for two thermotropic liquid crystalline polymers. Initial coalescence via elastic contact was ruled out based ...
Using transient shear rheology to determine material parameters in fiber suspension theory
(AIP Publishing, 2009-05-01)
Fiber suspension theory model parameters for use in the simulation of fiber orientation in complex flows are, in general, either calculated from theory or fit to experimentally determined fiber orientation generated in ...
Vehicle fleet emissions of black carbon, polycyclic aromatic hydrocarbons, and other pollutants measured by a mobile laboratory in Mexico City
(Copernicus Publications, 2005-12-01)
Black carbon ( BC) and polycyclic aromatic hydrocarbons (PAHs) are of concern due to their effects on climate and health. The main goal of this research is to provide the first estimate of emissions of BC and particle-phase ...
Metastability of multitwinned Ag nanorods: Molecular dynamics study
(American Physical Society, 2008-07-16)
Nanoscale rods have been shown to exhibit a multiple twinned structure. The rods grow along a -type crystallographic direction and have a pentagonal cross section with five (111) twins connecting the wire center to ...
Modification Of Spontaneous Emission in Bragg Onion Resonators
(Optical Society of America, 2006-03-01)
We formulated an analytical model and analyzed the modification of spontaneous emission in Bragg onion resonators. We consider both the case of a single light emitter and a uniformly distributed ensemble of light emitters ...
