    Compilation of data on model cheeses composition

    Mar 31, 2021 · This paper presents data on model cheeses extracted from the BaGaTel database. The data are issued from 6 different research projects in which data on composition, rheological and sensory properties were collected. The manufacturing of the 68 different samples is described. For each model cheese, data are available on final composition (lipid, protein, water, sodium), rheological Effects of Aging on the Physical and Rheological May 01, 2021 · Furthermore, dynamic shear rheological (DSR) tests were undertaken before and after aging to measure the complex shear modulus and phase angle of the modified binders, as well as to calculate zero shear viscosity using the Cross model fitting procedure. The rolling thin film oven test (RTFOT) was used to simulate short-term aging.

    REU Research Projects. Projects include experimental, computational, and theoretical work in a vareity of areas within or related to materials physics. Completion of a first-year physics or chemistry course sequence is a prerequisite for all projects. Additional prerequisites are noted in the project descriptions. Rapid Rheological Testing of Wheat Gluten and Dough The main expected outcome is a rapid test for the rheological properties of hydrated wheat. Current rheological tests based on expensive rheometers are limited to the laboratory and are time consuming, which limits the number of samples that can be checked. The essence of wheat for the end user is its blend of viscosity (or flow) and elasticity.

    Research on the viscous flow transition of styrene

    Apr 11, 2021 · The viscous flow transition of triblock copolymer styrene-isoprene-styrene (SIS5562) was studied by rheological methods. A broad loss factor (tan \(\delta\)) peak at 152.5 appeared on the dynamic viscoelastic spectrum under experimental conditions.Some similar peaks had been attributed to order-order transition (OOT) or order-disorder transition (ODT) in some research. Rheological Properties and Microstructure of Canola-Based This work evaluated eight different emulsions produced with canola oil and stabilized using two different polyoxyethylene sorbitan surfactants (Tween® 60 or Tween® 85), by evaluating their microstructure and rheological properties. The results showed that the canola-based emulsion behaved as non-Newtonian fluids with pseudoplastic character (n or nH <0.7).

    Polymers show complex rheological behavior which needs to be considered when using or producing these kinds of materials, like the viscosity of the melt, flow behavior, viscoelastic properties, temperature-dependent behavior, glass transition temperature, aging behavior, etc. Various tests and analysis methods are employed to optimize the polymer properties until they meet all requirements.Rheological behavior and sensitivity of wood-derived bio of bio-asphalt by penetration, softening point, and ductility. The test results indicated that, using a mixture of bio-oil and modied asphalt, the penetration declined with an increase in the proportion of modied asphalt, and ductility improved greatly, which corrected with the disadvantages of hard and brittle bio-asphalts at low temperatures.
