Non‐Additive Criteria Assessment in Sustainability Evaluation of High Entropy Alloys: A Toxicity‐Weighted Framework

open access: yesAdvanced Engineering Materials, EarlyView.
Sustainability assessment requires methodologies that appropriately distinguish between additive and non‐additive material properties. A toxicity‐weighted scoring system is developed and applied that accounts for the disproportionate influence of highly toxic constituents through nonlinear weighting functions, providing more realistic estimates than ...

Socioeconomic Complexity and the Sociological Tradition: New Wine in Old Bottles [PDF]

open access: yes
Complexity is a purposeful integrating framework for interdisciplinary dialogue, namely between sociologists and economists. After presenting some properties of complex (social) systems, we consider the crucial role of the economic complexity research ...

Simulation‐Based Analysis of Insert Pull‐Out in Nickel‐Polyurethane Hybrid Foams Using CT‐Derived Geometries

open access: yesAdvanced Engineering Materials, EarlyView.
CT‐based finite element simulations combined with in situ X‐ray computed tomography are used to analyze insert pull‐out in nickel‐coated polymer foams. Despite variations in material parameters, deformation consistently concentrates within a narrow annular region around the insert.

A Novel Approach to Estimate the Transition Temperature via Dynamic Nanoindentation

open access: yesAdvanced Engineering Materials, EarlyView.
A new dynamic nanoindentation‐based method was developed that uses the stiffness ratio as an indicator of the elastic–plastic deformation contributions at different temperatures. The approach successfully identified transition temperatures in ferritic steel and distinguished them from continuously ductile austenitic steel.

On the complexity of the economic lot-sizing problem with remanufacturing options [PDF]

open access: yes
In this paper we investigate the complexity of the economiclot-sizing problem with remanufacturing (ELSR) options. Whereas inthe classical economic lot-sizing problem demand can only besatisfied by production, in the ELSR problem demand can also ...

Anticorrosive Performance of Smart Epoxy Coatings With Poly(urea‐formaldehyde) Microcapsules Filled With 5‐Ethylidene‐2‐norbornene

open access: yesAdvanced Engineering Materials, EarlyView.
PUF/ENB microcapsules were synthesized based on a sequential factorial design and incorporated into an epoxy matrix. Their anticorrosive action, associated with the self‐healing mechanism, demonstrated that the addition of microcapsules to the coating improved anticorrosive performance compared to pure epoxy coatings, particularly when the encapsulate ...

Digital Light Processing of Thermoplastic Poly(methyl methacrylate) Photoresin Combined With Solvent Vapor Smoothing

open access: yesAdvanced Engineering Materials, EarlyView.
A thermoplastic PMMA‐based photoresin enables high‐resolution DLP printing followed by solvent‐vapor smoothing. The treatment reduces staircase‐induced surface roughness from 2.33 µm to 129 nm and increases visible‐light transmittance from approximately 30% to 80%, providing a route toward transparent PMMA components for rapid prototyping and non ...

Building economic complexity in Africa [PDF]

open access: yes, 2019
The paper reports on and summarizes four country case studies (Ghana, Kenya, Senegal and South Africa) in terms of: the degree and extent of economic complexity; a detailed product space analysis; firm interviews to identify what prevents or enables ...
