Mode-coupling approach to non-Newtonian Hele-Shaw flow

, 2002
The Saffman-Taylor viscous fingering problem is investigated for the displacement of a non-Newtonian fluid by a Newtonian one in a radial Hele-Shaw cell.

Electrochemical Evaluation of Compressed Selective Laser Melted AlSi7Mg and AlSi10Mg Alloys in Chloride Environment

Advanced Engineering Materials, EarlyView.
The corrosion performance of AlSi7Mg and AlSi10Mg alloys produced through selective laser melting (SLM) was examined under compressive stress in a chloride environment. Electrochemical analyses, including open‐circuit potential (OCP), potentiodynamic polarization (CPP), and electrochemical impedance spectroscopy (EIS), were complemented by scanning ...

Surface energy-driven electrodeposition stability in sodium metal electrodes

JPhys Energy
Dendrite growth arising from interfacial instability remains a major obstacle to the advancement and commercialization of metal anode-based batteries. Sodium metal batteries (SMBs), a promising alternative to lithium (Li)-based systems due to the broad ...

Room temperature spin relaxation in GaAs/AlGaAs multiple quantum wells [PDF]

, 1998
We have explored the dependence of electron spin relaxation in undoped GaAs/AlGaAs quantum wells on well width (confinement energy) at 300 K. For wide wells, the relaxation rate tends to the intrinsic bulk value due to the D'yakonov-Perel (DP) mechanism ...

Innovative Processing of Compacted Waste Aluminum Alloy Powders via Controlled Remelting and Solidification

Advanced Engineering Materials, EarlyView.
This study demonstrates an efficient recycling route for out‐of‐spec AlSi10Mg atomized powders through compaction and arc remelting followed by suction casting. By correlating compaction load, cooling rate, and resulting microstructure, we show that intermediate pressures (50–80 kN) and rapid cooling refine dendrites, reduce porosity, and enhance ...

Morphology Analysis and Optimization: Crucial Factor Determining the Performance of Perovskite Solar Cells

Molecules, 2017
This review presents an overall discussion on the morphology analysis and optimization for perovskite (PVSK) solar cells. Surface morphology and energy alignment have been proven to play a dominant role in determining the device performance.

Defects in Lamellar Diblock Copolymers: Chevron- and Omega-shaped Tilt Boundaries

, 2000
We investigate symmetric grain boundaries in a lamellar diblock copolymer system. The form of the interface between two grains strongly depends on the angle $\theta$, between the normals of the grains.

Interface morphologies in liquid/liquid dewetting

Chemical Engineering and Processing: Process Intensification, 2011
The dynamics and morphology of a liquid polystyrene (PS) film on the scale of a hundred nanometer dewetting from a liquid polymethylmethacrylate (PMMA) film is investigated experimentally and theoretically. The polymers considered here are both below their entanglement lengths and have negligible elastic properties. A theoretical model based on viscous

Zein‐Based Adhesives: Sustainable Extraction and Application in Bioadhesive Technologies

Advanced Engineering Materials, EarlyView.
Zein is extracted from corn gluten meal using a simple and scalable process with high yield (~90%). The resulting protein is applied in bioadhesives modified with Ca2+ and Fe3+ ions, exhibiting substrate‐dependent adhesion. The findings demonstrate competitive bonding performance and highlight the role of ionic interactions in tuning adhesion ...

Morphology and its Interfaces

The Buckingham Journal of Language and Linguistics, 2011
Morphology and it Interfaces is a composite volume presenting eleven chapters and at least as many distinct voices from eighteen contributors. As such, a degree of divergence in topic, theoretical standpoint and tone has to be accepted. The volume does not seek to resolve these differences beyond utilisation of a basic thematic division around the ...
