Structural and viscosity studies of dendritic hyper branched polymer as viscosity index improvers. [PDF]
BMC ChemAbstractStar-like structural compounds were synthesized from different moles % of either dodecyl acrylate or triethylenetetramine using a one-pot commercial synthesis technique. The polymers that were created had various terminations. Fourier Transform Infrared (FTIR) spectroscopy and 1HNMR were used to verify the produced polymers' chemical ...

Extension of the dielectric breakdown model for simulation of viscous fingering at finite viscosity ratios [PDF]
, 2014 Immiscible displacement of viscous oil by water in a petroleum reservoir is often hydrodynamically unstable. Due to similarities between the physics of dielectric breakdown and immiscible flow in porous media, we extend the existing dielectric breakdown ...

Thermophysical properties of a Cu46Zr42Al7Y5 bulk metallic glass-forming liquid [PDF]
, 2006 The thermophysical properties, including the specific volume V, the surface tension sigma, and the viscosity eta, of a Cu46Zr42Al7Y5 bulk metallic glass in the molten state were investigated using a containerless high-temperature high-vacuum ...

Comment on the power law in rheological equations [PDF]
, 2008 In conformity with the principle of shear reversal, it is proposed that the power law index in the Cross equation relating steady state viscosity to shear rate in semisolid alloy slurries should have a value of 4/3, which is independent of alloy system ...

A Viscosity Method for the Min-Max Construction of Closed Geodesics [PDF]
, 2015 We present a viscosity approach to the min-max construction of closed geodesics on compact Riemannian manifolds of arbitrary dimension. We also construct counter-examples in dimension $1$ and $2$ to the $\varepsilon$-regularity in the convergence ...

Probing equilibrium glass flow up to exapoise viscosities [PDF]
, 2015 Glasses are out-of-equilibrium systems aging under the crystallization threat. During ordinary glass formation, the atomic diffusion slows down rendering its experimental investigation impractically long, to the extent that a timescale divergence is ...

Local transient rheological behavior of concentrated suspensions [PDF]
, 2011 This paper reports experiments on the shear transient response of concentrated non-Brownian suspensions. The shear viscosity of the suspensions is measured using a wide-gap Couette rheometer equipped with a Particle Image Velocimetry (PIV) device that ...

Dual refractive index and viscosity sensing using polymeric nanofibers optical structures [PDF]
, 2019 Porous materials have demonstrated to be ideal candidates for the creation of optical sensors with very high sensitivities. This is due both to the possibility of infiltrating the target substances into them and to their notable surface-to-volume ratio ...
