Radiative Hybrid Nanofluid Flow Over a Porous Riga Surface: A Fuzzy–ANN Modeling Approach

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study proposes a fuzzy–ANN model to investigate the nonlinear thermal transport in a tangent hyperbolic (Tanh) hybrid nanofluid flow past a porous Riga surface, considering the effects of Rosseland diffusion, chemical reactions, and internal volumetric heating.

Fractal dimension for fractal structures: A Hausdorff approach

open access: yesTopology and its Applications, 2012
This paper provides a new model to compute the fractal dimension of a subset on a generalized-fractal space. Recall that fractal structures are a perfect place where a new definition of fractal dimension can be given, so we perform a suitable discretization of the Hausdorff theory of fractal dimension.

Synergistic Effect on Enhanced Oil Recovery in High Salinity Carbonate Reservoirs Using a Novel PEI‐Functionalized Carbon Nanotube Nanocomposite

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Enhancing oil recovery (EOR) in mature reservoirs is hindered by high interfacial tension (IFT) and oil‐wet rock formations, especially under harsh, high‐salinity conditions. This study aims to overcome these limitations by synthesizing a novel carbon nanotube nanocomposite covalently grafted with polyethylenimine and non‐covalently ...

Effect of Carboxymethyl Chitosan and Genipin on the Structural, Water Uptake, and Thermomechanical Properties of Zein‐Based Biodegradable Materials

open access: yesJournal of Applied Polymer Science, EarlyView.
The effects of carboxymethyl chitosan and genipin on zein‐based biodegradable materials have been investigated. The addition of these compounds alters the material's structure, water absorption, and thermomechanical behavior, while genipin enhances mechanical performance through the formation of polymer networks.

What Makes A Business Ecosystem Circular? A Multilevel Review

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Drawing on multilevel and complexity theories, this research identifies new and reframed core principles of circular business ecosystems (CBEs), thereby clarifying what makes a business ecosystem circular. Although CBEs are increasingly recognised as adaptive systems shaped by interdependencies and non‐linear interactions, how circularity ...

Revisiting Graphite Electrodes for Electric Arc Furnaces: Three‐Dimensional Microstructural Heterogeneity as a Design Parameter for Fracture Resistance

open access: yesCarbon Innovation, EarlyView.
Graphite electrodes are revisited as strategically important carbon materials for electric arc furnace steelmaking. By correlating three‐dimensional microstructural complexity with fracture energy, this work reveals a fundamental trade‐off between graphitization and energy dissipation, providing a data‐driven framework for the rational redesign of ...
