A Thermodynamic 3D Model for the Simulation of Diffusion‐Controlled Alloying Processes in Heterogeneous Material Structures

open access: yesAdvanced Engineering Materials, EarlyView.
A numerical model resulting from irreversible thermodynamics for describing transport processes is introduced, focusing on thermodynamic activity gradients as the actual driving force for diffusion. Implemented in CUDA C++ and using CalPhaD methods for determining the necessary activity data, the model accurately simulates interdiffusion in aluminum ...

Setup‐Optimized Sequencing in Job Shops: Modeling Workstation Productivity and Lateness Behavior

open access: yesAdvanced Engineering Materials, EarlyView.
Setup‐optimized sequencing in job‐shop production creates a trade‐off between productivity improvement and schedule reliability. A WIP‐explicit modeling framework links sequencing‐induced productivity gains and lateness dispersion through the production operating curve.

The Density of Primes Less or Equal to a Positive Integer up to 20,000: Fractal Approximation

open access: yesRecoletos Multidisciplinary Research Journal, 2013
The highly irregular and rough fluctuations of the number of primes less or equal to a positive integer x for smaller values of x ( x≤20,000) renders the approximations through the Prime Number Theorem quite unreliable. A fractal probability distribution

Novel Tailoring of Ternary ZnS‐MXene‐TiO2 Nanocomposite Heterojunction and Its Tunable Electrochemical Properties With Enhanced Photocatalytic Degradation

open access: yesAdvanced Engineering Materials, Volume 28, Issue 11, 3 June 2026.
ZnS‐MXene‐TiO2 nanocomposite heterojunction for photocatalytic decomposition of this methylene blue dye (MB) greatly improves light absorption, charge separation, and active site area. Two‐dimensional MXene forms nanocomposites by easily combining them with 0D (quantum dots), 1D (tube and wire), 2D (plane and sheet), and 3D (particle and lamellar ...
