We calculate the length distribution of linear micelles modeled as living bead-spring chains from a simple mesoscopic model. Within the framework of statistical mechanics an expression for the free energy is used. For the case of Rouse chains the length distribution and rheological properties we evaluate as functions of the micellar concentration, the scission energy, and the strength of an app...

in this study, the possibility of including probiotic starter cultures for making yoghurt was investigated. set yoghurts were made using three bio-cultures, all containing bifido-bacterium spp.. the effects of these starter cultures and total solids (i.e. addition of 0, 1 and 2% skim milk powder) on the rheological and sensory characteristics of the bio-yoghurts were compared with a standard st...

Microrheology can be used for high-throughput screening of the rheological properties of sample libraries of complex fluids. Two passive techniques are particularly suitable: video microscopy and diffusing-wave spectroscopy. The techniques complement each other very well and can be applied to samples that offer different experimental challenges. We offer a thorough analysis of the strengths and...

The magneto-rheological fluid Dual Clutch Transmission (MDCT for short) adopts the magneto-rheological (MR for short) effect of magneto-rheological fluid (MRF for short) and the working characters of Dual-Clutch Transmission (DCT for short), and combines the characteristics with long service life, no wear, simple structure, accurate control of MR effect with the principles of DCT technology, it...

This study investigates the effects of nanostructure size and surface area on the rheological properties of un-cross-linked poly(propylene fumarate) (PPF) nanocomposites and the mechanical properties of cross-linked nanocomposites as a function of the nanostructure loading. Three model carbon nanostructures were examined, C(60) fullerenes, ultra-short single-walled carbon nanotubes (US-tubes) a...

Rheological properties are very important parameters in the production of products with high-quality and desirable texture. So far, many attempts to produce low-calorie milk chocolate have not succeeded. Therefore, the present study aims to evaluate the effects of sugar substitutes on rheological characteristics of prebiotic milk chocolate using Simplex-lattice mixture design. For doing this, a...

The local mechanical properties of cells are frequently probed by force indentation experiments carried out with an atomic force microscope. Application of common contact models provides a single parameter, the Young's modulus, to describe the elastic properties of cells. The viscoelastic response of cells, however, is generally measured in separate microrheological experiments that provide com...

The rheological properties of cholesteric liquid crystals containing networks of defects are investigated. A network of linear defects of the "oily-streak" type is stabilized when colloidal particles are dispersed into the cholesteric liquid crystals. This network converts the rheological response of a presheared cholesteric liquid crystal from fluidlike to solidlike and leads to the formation ...

The kinetics and mode of nucleation and growth of fibers by 5R-cholestan-3â-yl N-(2-naphthyl)carbamate (CNC), a low-molecular-mass organogelator (LMOG), in n-octane and n-dodecane have been investigated as their sols were transformed isothermally to organogels. The kinetics has been followed in detail by circular dichroism, fluorescence, small-angle neutron scattering, and rheological methods. ...
