Application of operator splitting to solve reaction-diffusion equations
Electronic Journal of Qualitative Theory of Differential Equations, 2012 Approximate solutions of systems of semilinear ordinary differential equations obtained by different splitting methods are investigated. The local error in the numerical solution of such semilinear problems is evaluated.

Advanced Engineering Materials, EarlyView.Carbon‐free inert anodes are essential for decarbonizing aluminum electrolysis. This study investigates a recyclate‐based MgO‐316L steel composite anode tested under galvanostatic Hall–Héroult conditions in cryolite at 1000°C. Microstructural analysis reveals selective MgO fluorination, spinel and oxide layer formation, electrolyte infiltration, and ...

Advanced Engineering Materials, EarlyView.The formation of nonmetallic inclusions (NMIs) was investigated in this study, carrying out immersion tests for 30 min at a temperature of 1600°C with liquid high‐silicon electrical steel (Si ≈ 3 mass‐%) and different MgO–C refractories. Conventional MgO–C refractories were considered, as well as MgO–C refractories containing MgO–C recyclate and ...

Depinning transitions in discrete reaction-diffusion equations
, 2002 We consider spatially discrete bistable reaction-diffusion equations that admit wave front solutions. Depending on the parameters involved, such wave fronts appear to be pinned or to glide at a certain speed. We study the transition of traveling waves to

On the nonnegatibity of solutions of reaction diffusion equations
Rocky Mountain Journal of Mathematics, 1987 Consider the system of reaction diffusion equations \[ \partial u/\partial t=A\Delta u+f(u,\nabla_ xu,x,t)\quad (*) \] where A is a \(p\times p\) matrix, u(x,t) is a p-dimensional vector with components \(u^{(j)}(x,t)\), \(j=1,...,p\) and where \((x,t)\in {\mathbb{R}}^ n\times (0,\infty)\).

Assessing Altered Coating Adhesion on Plasma‐Deoxidized Surfaces Under Oxygen‐Free Conditions
Advanced Engineering Materials, EarlyView.This study demonstrates the effectiveness of atmospheric pressure plasma pretreatment in modifying silicon and stainless steel surfaces to improve adhesion. Argon‐hydrogen plasma increases surface roughness and improves adhesion strength, whereas pure argon results in smoother surfaces and structural changes.
