Study on the mechanism of polyvinyl alcohol (PVA) polymerization degree on the rheological regulation of cement-based materials: A multi-scale simulation analysis based on adsorption

Results in Engineering
As a common concrete thickener, Polyvinyl alcohol (PVA) affects cement paste rheology depending on its degree of polymerization (DP). This study examines the influence of PVA DP on rheology using TOC, zeta potential tests, and molecular dynamics.

Dynamics and electro-rheology of sheared immiscible fluid mixtures

, 2014
We analyze the electro-rheological effect in immiscible fluid mixtures with dielectric mismatch. By taking the electric field effect into account, which couples to the dynamics of domain morphology under flow, we propose a set of electro-rheological ...

PLA/PA bio-blends: induced morphology by extrusion [PDF]

, 2019
The effect of processing conditions on the final morphology of Poly(Lactic Acid) (PLA) with bio-based Polyamide 10.10 (PA) 70/30 blends is analyzed in this paper. Two types of PLA were used: Commercial (neat PLA) and a rheologically modified PLA (PLAREx),

Nanorheology of Interfacial Water during Ice Gliding

Physical Review X, 2019
The slipperiness of ice is an everyday-life phenomenon, which, surprisingly, remains controversial despite a long scientific history. The very small friction measured on ice is classically attributed to the presence of a thin self-lubricating film of ...

Rheology of Non-Dilute Emulsions: A Comprehensive Review

Colloids and Interfaces
Non-dilute emulsions are emulsions where the concentration of the droplets is high enough for the neighbouring droplets to interact with each other hydrodynamically but is still smaller than the packed bed concentration where the droplets are packed and ...

Maxwell stress in fluid mixtures

, 2012
We examine the structure of Maxwell stress in binary fluid mixtures under an external electric field and discuss its consequence. In particular, we show that, in immiscible blends, it is intimately related to the statistics of domain structure.

A novel method for investigating ice-substrate interfacial rheology and long-term adfreeze strength through loading-unloading creep test

Case Studies in Construction Materials
Ice cementation and ice-substrate adfreeze force are the primary contributors to the high bearing capacity of pile foundations in cold regions and the stability of frozen walls in areas subjected to artificial freezing.

Effect of Marangoni stress on the bulk rheology of a dilute emulsion of surfactant-laden deformable droplets in linear flows

, 2017
In the present study we analytically investigate the deformation and bulk rheology of a dilute emulsion of surfactant-laden droplets suspended in a linear flow.
