Viscosity in Modified Gravity [PDF]
Entropy, 2012 A bulk viscosity is introduced in the formalism of modified gravity. It is shownthat, based on a natural scaling law for the viscosity, a simple solution can be found forquantities such as the Hubble parameter and the energy density. These solutions mayincorporate a viscosity-induced Big Rip singularity.

Review of Viscosity Modifier Lubricant Additives [PDF]
Tribology Letters, 2018 This article reviews viscosity modifiers, additives that increase the viscosity of lubricating oils. Viscosity modifiers are high molecular weight polymers whose functionality is derived from their thickening efficiency, viscosity–temperature relationship, and shear stability.

Dynamical heterogeneity in aging colloidal glasses of Laponite [PDF]
, 2012 Glasses behave as solids due to their long relaxation time; however the origin of this slow response remains a puzzle. Growing dynamic length scales due to cooperative motion of particles are believed to be central to the understanding of both the slow ...

Study on new viscosity modifying agents [PDF]
Advances in Engineering Research, 2015 In this work, we synthesized a new viscosity modifying agents with AA, AM as monomer and ammonium persulfate as initiator. Through the discussion on the AA dosage, the polymerization conditions, we determined the optimum technological conditions of the new VMA: the optimum molar ratio of AA to AM is 1:1, the dosage of initiator is 2wt% of all the ...
