Rheology of concentrated disperse systems and minimum energy dissipation principle. i. viscosity-concentration relationship.
TLDR
In this paper, a new viscosity-concentration relationship is deduced from the optimization of viscous energy dissipation for concentrated disperse systems, exhibiting newtonian behavior.Abstract:
For concentrated disperse systems, exhibiting newtonian behaviour, a new viscosity-concentration relationship is deduced from the optimization of viscous energy dissipation. Comparison with several theoretical and experimental investigations gives satisfactory agreement up to packing concentrations.read more

Colloidal Suspension Rheology
Jan Mewis,Norman J. Wagner +1 more
TL;DR: In this paper, the authors introduce colloid science and rheology, and present an overview of colloid physics and its applications in viscoelastic media. But they do not discuss the role of non-spherical particles.

Recognition, classification and mechanical description of debris flows
Philippe Coussot,M. Meunier +1 more
TL;DR: In this paper, a synthesis of the useful practical criteria of recognition is proposed, and two extreme debris flow types are thus distinguished: muddy debris flows and granular debris flows, and a critical review of recent advances in debris flow dynamic is then proposed.

2D-Crystal-Based Functional Inks
TL;DR: The exfoliation strategies of graphite and other layered crystals are reviewed, along with the advances in the sorting of lateral size and thickness of the exfoliated sheets together with the formulation of functional inks and the current development of printing/coating processes of interest for the realization of 2D-crystal-based devices.

Electrosteric Stabilization of Colloidal Dispersions
TL;DR: In this paper, the electrosteric stabilization of model colloidal dispersions is quantified through high-frequency rheometry and complementary techniques, using a poly(butyl acrylate)−pol...

Review of techniques to manufacture micro-hydrogel particles for the food industry and their applications
TL;DR: The utilisation of engineered microgels in foods has so far been limited, despite their great potential to address several needs in the food industry, including satiety control, encapsulation of phytonutrients and prebiotics, texture control for healthier food formulations, and targeting delivery to specific areas in the digestive tract.

Percolation and Conduction
TL;DR: In this article, an extension of percolation theory to treat transport is described, and a general expression for the conductance of such networks is derived, which relates to the spin-stiffness coefficient of dilute ferromagnet.
Journal ArticleDOI
The Viscosity of Concentrated Suspensions and Solutions
TL;DR: In this paper, an expression for the viscosity of solutions and suspensions of finite concentration is derived by considering the effect of the addition of one solute-molecule to an existing solution, which is considered as a continuous medium.

The Viscosity of a Fluid Containing Small Drops of Another Fluid
TL;DR: In this article, it was shown that if the radius of the suspended drops or the velocity of distortion of the fluid are small, surface tension may be expected to keep them nearly spherical, and in that case Einstein's analysis may be extended so as to include the case of liquid drops.

The viscosity of a concentrated suspension of spherical particles
TL;DR: In this paper, the authors extended the viscosity equation for an infinitely dilute suspension of spheres to apply to a suspension of finite concentration, and made use of a functional equation which must be satisfied if the final viscosities is independent of the sequence of stepwise additions of partial volume fractions of the spheres to the suspension.

The viscosity of the blood in narrow capillary tubes
Robin Fåhræus,Torsten Lindqvist +1 more
TL;DR: Objections have been made from a theoretical point of view that the results of investigations of the viscosity of the blood in comparatively wide capillary tubes probably do not apply to the conditions in the narrower parts of the vascular system, whereby these authors especially seem to have had the true capillaries in view.
