Productivity for Horizontal Wells in Low‐Permeability Reservoir with Oil/Water Two‐Phase Flow [PDF]

open access: yesMathematical Problems in Engineering, 2014
This paper presents a semianalytical steady‐state productivity of oil/water two‐phase flow in low‐permeability reservoirs with both top and bottom boundaries closed which takes the permeability stress‐sensitive and threshold pressure gradient into account. Using the similar approach as Joshi’s (1988), the three‐dimensional (3D) horizontal well problem

Exploring an Alternative to mRNA Vaccine Cold Chain Storage: MRNA‐Lipid Nanoparticle Stability When Dried in a Polymer Matrix

open access: yesAdvanced Functional Materials, EarlyView.
The nanostructure, size, and function of mRNA‐loaded lipid nanoparticles are evaluated before drying, within polymer microneedles, and after rehydration. The results reveal the polymer and LNP loadings required to recover nanostructure and preserve the delivery performance in dry‐state formulations.

Myrcene‐Based Tailored Co‐Polymers as Active Pharmaceutical Excipients: Bio‐Based Solutions for Mucoadhesive Excipients

open access: yesAdvanced 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 ...

Complex network analysis of phase dynamics underlying oil-water two-phase flows [PDF]

open access: yesScientific 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.

Chemical Maturation Controls Bioavailability of Fetuin‐A‐Mineral Complexes in Biomineralization

open access: yesAdvanced Functional Materials, EarlyView.
The role of Fetuin‐A‐mineral complexes in matrix mineralization is unclear. Here, Fetuin‐A‐mineral complexes were found to exist in functionally distinct states that determine mineral bioavailability: chemically labile calciprotein monomers directly mineralize collagen fibrils, while chemically matured primary calciprotein particles require cellular ...

Effect of Crude Oil-Water Two-Phase Flow on Pump Performance

open access: yesEngineering 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.

Electrospun Wood‐Derived Biopolymers as Electrodes in Electrochemical Energy Storage Technologies

open access: yesAdvanced Functional Materials, EarlyView.
Electrospinning transforms wood‐derived cellulose and lignin into architecturally defined, binder‐free carbon electrodes with tuneable porosity and functionality. This review shows how fibre design enables decoupled charge and mass transport, enhancing performance across battery systems, while identifying key challenges in spinnability, scalability ...

Modeling of Two-Phase Flow in Rough-Walled Fracture Using Level Set Method

open access: yesGeofluids, 2017
To describe accurately the flow characteristic of fracture scale displacements of immiscible fluids, an incompressible two-phase (crude oil and water) flow model incorporating interfacial forces and nonzero contact angles is developed.
