Measuring particle alignment in particleboard and predicting selected mechanical properties of oriented boards
Particle orientation in particleboard was characterized by two directional distribution functions, the von Mises and truncated gaussian. This approach has the advantage of characterizing the degree of orientation by specifying only one parameter. A method was developed to measure the orientation of …

Rheology and Microstructure of Concentrated Suspensions of Plate-Shaped Colloidal Particles
The second type of clay particles have a smaller aspect ratio approximately equal to 8. These suspensions demonstrate shear thickening at $\phi \ge$ 0.50 and also have a shear history dependent elastic modulus, G$\sp\prime.$ In the shear thinning region G$\sp\prime$ decreases with increasing shear …

Large Scale Simulation of Plate-Like Particle Suspensions
… shear thickening of suspensions of plate-like particles are studied. It is found that shear thinning is caused by both the decrease of the strength of the Brownian motion and the decrease of the hydrodynamic contribution to the viscosity resulting from the increasing particle alignment induced …

Quantitative Analysis of Microstructural Evolution in Polycrystalline Metal Matrix with Embedded Second Phase Particle
… methodology, the role of inert, secondary particles on the dynamics of grain boundaries under conditions of uncooperative migration has been analyzed. Systematic studies have been carried out to understand the influence of various particle shapes on the motion of the grain boundaries with a …

Magneto-elastic behavior in hard- and soft-MRE's including demagnetizing effects
… on four possible permutations defined along particle alignment (Aligned and Unaligned) and magnetization (Hard- or Soft-magnetic) pairs. These pairs designations yield classes A-H, U-H, A-S and U-S. The last two classes comprise traditional MREs. Samples were fabricated by mixing DOW HS II …

Optical properties of concentrated dispersions
… has been investigated for non-spherical particles in concentrated dispersions, over a range of pH and surfactant concentrations. Measurements of diffuse transmittance and reflectance required large corrections to be made £->r the presence of any specular interfaces i.e. windows. These …

Mechanism of anaesthetic activation, combination and antagonism
… fragments have been used in the past to support particle alignment and distribution in cryo-EM specimen. On the example of several cryo-EM structures, I will discuss the impact and necessity of such fiducials. Anaesthetics are thought to target the inter-subunit clefts of several pLGICs in the …

Microfabric changes during the deformation of clays.
… as these permit the evaluation of the degree of particle orientation anisotropy at any direction to . the principle stress direction. The change of particle orientation of kaolin subjecte d to various conditions of consolidation has been discussed. It was found that the increase in particle …

Cellulose Nanocrystals: Size Characterization and Controlled Deposition by Inkjet Printing
Inkjet printing has generated considerable interest as a technique for the patterning of functional materials in the liquid phase onto a substrate. Despite its high promise, the phenomena associated with inkjet printing remain incompletely understood. This research project investigates inkjet …

Microfluidics at high-intensity X-ray sources: from microflow chips to microfluidic liquid jet systems
… for the investigation of nanostructures, particle alignment, protein nanocrystals and the in situ study of kinetics. After covering the fundamental details of microfocused X-rays and microfluidics individually, this thesis reviews the combination of these technologies extensively. This …
