Odd viscosity in chiral active fluids [PDF]
, 2017 Chiral active fluids are materials composed of self-spinning rotors that continuously inject energy and angular momentum at the microscale. Out-of-equilibrium fluids with active-rotor constituents have been experimentally realized using nanoscale ...

Rheopexy and tunable yield stress of carbon black suspensions [PDF]
, 2012 We show that besides simple or thixotropic yield stress fluids there exists a third class of yield stress fluids. This is illustrated through the rheological behavior of a carbon black suspension, which is shown to exhibit a viscosity bifurcation effect ...

Single-Point Intrinsic Viscosity: Intrinsic Viscosity in the SEC-Viscometry
NIPPON GOMU KYOKAISHI, 2008 Many workers proposed an equation for a single point determination of intrinsic viscosity [η]. In these methods Solomon-Cuita's and Solomon Gotesman's equations were suitable with concentration of polymer c up to specific viscosity ...

The Hydrodynamic Radii of Viscosity Index Improvers for Lubricant Oils
Tribology Online, 2019 Viscosity index improvers are polymeric additives that are commonly used to control the viscometrics of lubricants. Nevertheless, there have been few studies on the molecular size of these additives, which is the origin of their viscosity-increasing ...

Intrinsic ambiguity in second order viscosity parameters in relativistic hydrodynamics
, 2012 We show that relativistic hydrodynamics in Minkowski space-time has intrinsic ambiguity in second order viscosity parameters in the Landau-Lifshitz frame. This stems from the possibility of improvements of energy-momentum tensor. There exist at least two

Intrinsic viscosity of a suspension of weakly Brownian ellipsoids in shear
, 2018 We analyze the angular dynamics of triaxial ellipsoids in a shear flow subject to weak thermal noise. By numerically integrating an overdamped angular Langevin equation, we find the steady angular probability distribution for a range of triaxial particle

Intrinsic Viscosity Determination by “Single-Point” and “Double-Point” Equations
Applied Rheology, 2009 “Single-point” equations used for intrinsic viscosity determination are greatly used when working with synthetic polymer solution systems. In this work we have applied them to a biological macromolecule in a bovine serum albumin (BSA)/water system ...
