Interfacial rheology of globular proteins
… etc. It is thus important to understand the interfacial behavior of protein-surfactant mixtures, especially the role it can play in bulk measurements of material properties. A complete description of the dynamics of these multi-component systems is still elusive. In this thesis, a …

Thermally driven visco-elastic measurement technique via spectral variations in scanning probe microscopy cantilevers
… this work addresses the need for probing interfacial rheology to understand how lubricants fail as system scales are reduced from bulk dimensions to molecular length scales. In the pursuit of interfacial rheology, one needs a platform capable of the temporal and spatial range and …

Integrating novel rheological tools with microscopy to characterize viscoelastic properties of complex materials
… of the available techniques in the field of microrheology and interfacial rheology and overcome them using the novel rheological techniques that we have developed. Passive particle tracking microrheology (PTM) is a technique that uses Brownian motion of colloidal probe particles to characterize …

Structure and Dynamics of Polyhedral Oligomeric Silsesquioxane (POSS) and Poly(Ethylene Glycol) (PEG) Based Amphiphiles as Langmuir Monolayers at the Air/Water Interface
… amphiphilic nanoparticles with controlled interfacial rheology.

Microgels at oil-water interfaces
… low pH. A number of different techniques, like interfacial tension measurements, interfacial rheology and cryogenic scanning electron microscopy, have been applied in order to obtain a comprehensive picture about the origin of these effects. As is turned out, the basic concepts developed for …

Bacteria At Oil-Water Interfaces
… accumulate, with hallmarks of soft glassy interfacial rheology. Finally, the interface is covered with a thin elastic solid film. On pendant drops covered with such films, the film wrinkles upon compression; the wavelength of these wrinkles allows estimation of the film's bending modulus. I …

Interfacial properties of saponins from Quillaja saponaria Molina and their functionality in dispersed systems
The aim of the present thesis was to connect interfacial properties of saponins at aqueous interfaces with their behavior in dispersed systems. Thereby the influence of changes in pH and ionic strength and interactions with β-lactoglobulin were discussed using spectroscopic equipment and knowledge …

Interfacial self-assemblies of surfactants at water-oil interfaces
… well-defined and relatively complex in shape. Interfacial rheology is utilized to understand viscoelastic properties of the interfacial layer made between the surfactant solution and oil phase. This gel-like material formed at the interface is robust enough that makes the printed liquid …

Effects of sucrose on the foaming and interfacial properties of egg white protein and whey protein isolate
… the air/water interface by lowering the interfacial tension and forming strong interfacial films. Sugars are known to influence the functional properties of protein foams. This study investigated the mechanism responsible for sucrose effects on the foaming and interfacial properties of …

Softmatter tribology: Understanding the microstructure to property relationships of hydrogel-like materials
… as well, where a prominent effect of the interfacial microstructure is observed on their mechanical and tribological properties. Yet, not only there is a lack of knowledge but also wide discrepancy about the fundamental underlying mechanisms relating the dynamic and static frictional …
