Two-phase flow of gas-liquid mixtures on horizontal helical pipes [PDF]
, 2007 The aim of this study was to investigate hydrodynamic two -phase (namely water and air) fluid flow characteristics in helical pipes of low amplitude and straight pipes of the same internal-diameter and constructional material: the results for the two ...

Advanced Functional Materials, EarlyView.Co‐delivery of electrosprayed EDOT and oxidant enables bulk oxidative polymerization during layer‐by‐layer fabrication, creating stable, highly conductive 3D PEDOT structures. This Atomized Oxidative Polymerization (AOP) overcomes the surface deposition‐only and matrix‐limited conductivity of conventional Vapor Phase Polymerization (VPP) and PEDOT:PSS ...

Effect of Crude Oil-Water Two-Phase Flow on Pump Performance
Engineering and Technology Journal, 2009 An experimental study of pump performance (i.e. head, discharge, power, etc.) was achieved by using a centrifugal pump with crude oil-water two-phase flow. The crude oil used was from Sherao oil field in Kirkuk (Iraq) with a density of 838 kg/m3, dynamic viscosity of 6.0 cP and surface tension of 0.027 N/m at a temperature of 25oC.

Complex network analysis of phase dynamics underlying oil-water two-phase flows [PDF]
Scientific Reports, 2016 AbstractCharacterizing the complicated flow behaviors arising from high water cut and low velocity oil-water flows is an important problem of significant challenge. We design a high-speed cycle motivation conductance sensor and carry out experiments for measuring the local flow information from different oil-in-water flow patterns.

Advanced Functional Materials, EarlyView.Mucoadhesive amphiphilic block and statistical copolymers were synthesized via Reversible Addition–Fragmentation Chain Transfer polymerization from bio‐sourced myrcene and polyethylene glycol methacrylate. The resulting polymers exhibit narrow molar‐mass distributions, high regioselectivity, well‐defined microstructures, and tend to self‐assemble into ...
