Nowadays a wide variety of different accessories used in combination with rotational rheomters are available. Such techniques range from rheo-optical methods to applying external pressures and electrical or magnetical fields. In addition systems transforming the rotational movement of the rheometer allow investigations on extensional rheology or tribology with a rheometer. INTRODUCTION Rheologi...

Several key challenges for rheologists working in the food industry are presented. These range from pure material science problems (complex yield behaviour, fracture mechanics of “soft” materials, interfacial rheology) and interactions with solid surfaces (wall slip) to the probably biggest challenge: the effects of rheology on processes inside the human body. Finally, the need for enhanced tea...

The determination of flow curves and the apparent viscosity curves at 28°C of creams containing human leukocyte alpha interferon as active principle is presented in this paper. These creams are used for the treatment of papiloma virus and herpes simplex. It is demonstrated that their behaviour corresponds to a thixotropic fluid. The Herschel-Bulkley model parameters are presented and discussed ...

An electro-rheological fluid is a material in which a particulate solid is suspended in an electrically non-conducting fluid such as oil. On the application of an electric field, the viscosity and other material properties undergo dramatic and significant changes. In this paper, the particulate imbedded fluid is considered as a homogeneous continuum. I t is assumed that the Cauchy stress depend...

We use a dynamic finite-difference model to simulate martian landslides in the Valles Marineris canyon system and Olympus Mons aureole using three different modal rheologies: frictional, Bingham, and power law. The frictional and Bingham modes are applied individually. Fluidized rheology is treated as a combination of frictional and power-law modes; general fluidization can include pore pressur...

Gels can be formed by dissolving Fmoc-diphenylalanine (Fmoc-PhePhe or FmocFF) in an organic solvent and adding water. We show here that the choice and amount of organic solvent allows the rheological properties of the gel to be tuned. The differences in properties arise from the microstructure of the fibre network formed. The organic solvent can then be removed post-gelation, without significan...
