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 ...

Application of nonintrusive reduced-order model for linear cross-diffusion Schnakenberg system
Mathematics in Applied Sciences and EngineeringThis study investigates nonintrusive reduced-order models (NIROMs) for parametric linear cross-diffusion systems. The full-order model (FOM) is constructed via discontinuous Galerkin spatial discretization and Kahan’s method for temporal integration ...

A multiflow approximation to diffusions
Stochastic Processes and their Applications, 1991 The author introduces a new form of approximation to diffusions represented as solutions of stochastic differential equations. In the various forms of approximations, one solves a sequence of ordinary differential equations which are derived by substituting, in place of Brownian path, a piecewise differentiable approximation corresponding to a given ...

Advanced Engineering Materials, EarlyView.This study explored how effective nickel aluminide coatings are obtained in providing oxidation resistance applied to the Inconel 738 alloy, modeling with diffusion models. In the present study, kinetics and thermal behavior of the Inconel 738 alloy were studied by the low‐temperature thermoreactive aluminizing process, which was carried out at 625°C ...

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 ...

A Compact Spin‐Coated Graphene UWB Antenna for Breast Tumor Detection
Advanced Engineering Materials, EarlyView.A compact, spin‐coated graphene ultra‐wideband patch antenna designed for breast tumor detection, capable of distinguishing between malignant and benign tumors. This innovative antenna can serve as an effective initial screening tool, particularly in resource‐limited settings such as rural areas, where access to advanced medical equipment like MRI and ...
