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 ...

Polymer Grafted Nanoparticle Viscosity Modifiers
Macromolecular Chemistry and Physics, 2019 AbstractIt is demonstrated that the addition of nanoparticles can decrease the viscosity of an entangled polymer matrix (plasticization). While there has been considerable effort in understanding the role of bare nanoparticles on viscosity, the corresponding study on grafted particles is nascent.

Modified Chaplygin gas cosmology with bulk viscosity [PDF]
International Journal of Modern Physics D, 2014 In this paper, we investigate the viscous modified Chaplygin gas cosmological model. Solutions for different values of the viscosity parameter are obtained using both analytical and numerical methods. We have calculated the deceleration and defined newly statefinder {r, s} pair in D dimensions.
