Concrete Rheology
The rheology of concrete is investigated in this work. The method involves using a partial experimental matrix that considers the effects of sand content, water/cement ratio, coarse aggregate type, fly ash content and the addition of a superplasticizer on the rheological parameters of yield stress, …

Extensional rheology of bread dough
We investigated the extensional properties of wheat flour dough on the Filament Stretching Rheometer (FISER), in which the sample approaches uniform uni-axial extension flow at a constant strain rate over a large portion of the experiment, thereby allowing us to directly probe the transient …

Interfacial rheology of globular proteins
… In this thesis, a comprehensive study of the rheology of a model globular protein solution is described. In conventional bulk rheological studies of globular protein solutions a yield-like behavior and shear thinning in the viscosity at low shear rates is observed, even for concentrations as …

Rheology of polyelectrolyte multilayer modified suspension
… investigate the effect of the layer number on rheology. At low layer numbers, the rheology suffers from an inhomogeneous PEM surface which introduces localized attractions to the suspensions. This results in a more brittle material as the local attractions are strong in radial direction, but …

Rheology and processing of mozzarella cheese
… commercial synthetic polymers. In this work, the rheology of mozzarella cheese was studied using well-developed rheological techniques. Utilizing various rheometers, the linear and non-linear rheology of mozzarella cheese was examined. General practical properties of mozzarella cheese such as …

Digital rheology of fresh-state concrete
… are essential to fully capture field test-rheology relationships. Relationships linking deposit height and diameter measurements to yield stress are established. Additionally, relationships between yield stress, flow cessation time, and viscosity are proposed. The second part ofthis thesis …

DNA-colloid systems and micro-rheology
… the behaviour of DNA-colloid systems using micro-rheology, with a view to demonstrating the efficacy of passive particle-tracking methodologies and developing entirely new systems. Chapter 1 introduces the fields of DNA coated colloids (DNACCs) and passive micro-rheology, with a particular fo cus …

Nonlinear rheology of micelles and polymers
… thesis is concerned with the theory of polymer rheology. 'Living polymers' are chain-like structures which closely resemble ordinary polymers, except that they can break and reform reversibly. The best-studied examples are wormlike surfactant micelles. A model for these systems has recently been …

Optical rheology for live cell membranes
We present a novel optical methodology including both instrumentation and theory aimed at retrieving the full viscoelastic information of cell membrane material properties. Red blood cells (RBC) are chosen for this study because of their simple structure, which consists of a bi-layer cell membrane …

The rheology of liquid crystal polymer blends.
The present studies are concerned with the observation and explanation of the interaction between liquid crystal and isotropic polymers. An investigation of the rheological behaviour has been carried out on blends containing small additions of a main chain thermotropic liquid crystal polymers using …

Rheology of molten polystyrene with dissolved gases
Dissolved gases in polymers behave as excellent plasticizers, reducing viscosity significantly through the chain dilution effect and the addition of free volume. Rheological measurements and theoretical modeling are presented for molten polystyrene with dissolved gases, including carbon dioxide, …

Soy protein-xanthan gum interaction:stability and rheology
This study investigated the effects of ionic strength, pH, gum concentration, and protein type on protein - xanthan gum interactions. Commercial soy sauce and tamari sauce as well as model systems of soy protein isolate and whey protein concentrate were the sources of protein used for evaluation …

Rheology and Collective Behavior in Living Tissue
<p>Recent experiments and simulations have indicated that confluent epithelial layers, where there are no gaps or overlaps between the cells, can transition from a soft fluid-like state to a solid-like state, with dynamics that share many features with glass transitions. While a coherent picture …

Rheology and Microstructure of Filled Polymer Melts
The states of particle dispersion in polymer nanocomposite melts are studied through rheological characterization of nanocomposite melt mechanical properties and small angle X-ray scattering measurement of the particle microstructure. The particle microstructure probed with scattering is related to …
