AbstractAchieving spatially uniform and hierarchically structured microstructures during the shape-forming of colloidal ceramics depends largely on (i) the magnitude of the effective stresses (i.e., stresses that are supported by the particulate network) and (ii) plastic properties, which in turn are significantly altered by processing parameters affecting interparticle friction and adhesion. To quantify the effects of processing parameters on consolidation, we present a novel approach for analyzing sediments by gamma-ray densitometry and a fluid mechanics model. This method enables us to correlate processing parameters with spatial variations of the packing density and the local effective stress. These correlations are difficult to achieve by traditional techniques (e.g., rheometry, sedimentation kinetics modeling, soil mechanics tests), especially for the low stresses (< 1000 Pa) that are typically encountered in sediments. Aside from being destructive to samples, these techniques also tend to measure volume-averaged properties, and as a result they usually fall short of describing localized consolidation phenomena.

ABSTRACTThe mass transporting properties of the surface relief grating (SRG) photofabrication on azobenzene polymer films is discussed precisely using an existing fluid mechanics model. Formulation for the SRG inscription rate is derived analytically from Navier-Stokes equation. In consequence, the dependence of inscription rate of the SRG on the experimental and geometrical parameters was explained very well by the model. The photoinduced surface deformation with an onedimensional Gaussian laser beam was also carried out in order to establish the validity and the generality of our fluid mechanics model. The experimentally obtained surface deformation profile is well reproduced by the theoretical model generalized for arbitrary force field profile.
