From laminar to turbulent: how methanogen and srb mic pathways shape their response to flow dynamics

npj Materials Degradation
Hydrodynamic conditions play a central role in microbiologically influenced corrosion (MIC) by regulating nutrient transport, metabolite removal, shear stress, and biofilm stability. As industrial systems operate across laminar and turbulent flow regimes,

Influence of Scan Strategies in Electron Beam Powder Bed Fusion on Solidification, Microstructure, and High‐Temperature Compressive Properties of γ′‐Strengthened Inconel 738LC

Advanced Engineering Materials, EarlyView.
Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...

Oil-water separation phenomenon due to corrosion cavity and scale sediments build-up in horizontal pipeline [PDF]

, 2012
The concurrent flow of two immiscible liquids (Oil-Water) in pipelines is usually encountered in oil production and pipeline transportation. Water is present in crude oil and separation facilities.

Effect of Laminar Flow on the Corrosion Activity of AA6061-T6 in Seawater

, 2020
The electrochemical behaviour and surface changes on AA6061-T6 alloy exposed to Caribbean seawater from the Cozumel Channel for 30 days under laminar flow (0.1 m s−1) were studied, contrasting then with stationary (no flow) conditions.

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

Advanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

A map and a pipe : a new approach to characterizing erosion-corrosion regimes of Fe in three dimensions using CFD modelling

, 2009
In studies of erosion-corrosion, much work has been carried out in recent years to identify regimes of behaviour. Such regimes describe the transition between the erosion and corrosion dominated mechanisms.

Inhibition of pitting on carbon steel [PDF]

, 2011
Carbon dioxide and hydrogen sulphide pitting related failures are a prime concern in oil and gas internal pipelines. Often, these types of failure have a great impact on safety and environmental matters and can cause severe financial consequences to the

Transfer Printing and Reconfiguration of Soft Electronics Using Digital Microfluidics and Laser Machining

Advanced Functional Materials, EarlyView.
This paper presents a digital microfluidics‐based technique for transferring and reconfiguring soft nanomembranes. Laser‐machined nanothin membranes are picked up, transported, and aligned via tailored surface tension and the actuation of water droplets, enabling the development of flexible electronics, the integration of functional materials on 3D ...

Tuning Separator Chemistry: Improving Zn Anode Compatibility via Functionalized Chitin Nanofibers

Advanced Functional Materials, EarlyView.
Nanochitin derived from waste shrimp shells is used to fabricate separators for aqueous zinc batteries. By tuning the density of amine and carboxylic surface groups, water mobility at the separator interface is controlled, promoting uniform zinc deposition, suppressing dendrite growth, and enabling exceptional cycling stability exceeding 2000 h ...

CFD modelling of erosion-corrosion of steel in aqueous environments : particle concentration effects on the regime boundaries

, 2010
In this study, a new methodology is used to model the effects of particle concentration on the inner surfaces of a circular pipe 90º bend, assuming applied potential controlled aqueous slurry flow at room temperature.
