Adaptive Foam 3D Printing of Ultralight and Multifunctional Materials

open access: yesAdvanced Engineering Materials, EarlyView.
Adaptive foam 3D printing, enabled by expandable microspheres, imparts cellular structures to thermoplastic and thermosetting polymers, manufactured through a variety of processes including fused filament fabrication, direct ink writing, digital light processing, and inkjet printing.

Discrepancies Between Micro Versus Macroscale Viscoelastic Properties in a Microplastic‐Tissue Composite Model

open access: yesAdvanced Engineering Materials, EarlyView.
This study explores the discrepancies between bulk mechanics and spatial mapping in a tissue‐mimetic hydrogel model. Microplastic particles create localized stiff mechanical microenvironments that are detectable by cellular‐scale nanoindentation but leave bulk properties unchanged as measured by rheology.

Design of a Multistable Finger Prosthesis with Programmable Metamaterials

open access: yesAdvanced Engineering Materials, EarlyView.
This research article shows the development of a multistable programmble metamaterial for the use as a finger prosthesis. The material was designed on different hierarchical levels where the influence of geometrical parameters and combination of mechanical elements was explored.

Theoretical advances in two-step iterative schemes for nonlinear problems

open access: yesTransactions on Computational Modeling and Intelligent Systems
This study develops a two-step iterative method for solving nonlinear equations, focusing on its convergence properties. Using Taylor series expansion, the method assumes the nonlinear function is at least four times continuously differentiable with ...

Morphology, Transport, and Dynamics of Protein Adsorption in Open‐Cell Metal Foam

open access: yesAdvanced Engineering Materials, EarlyView.
Stainless steel (SS) open‐cell foams are shown to adsorb more protein per unit area than previously reported 316L SS and chromium oxide surfaces under static and flow conditions. An integrated approach combining 3D pore imaging, flow simulation, and protein adsorption experiments characterizes the foam’s performance.

Agricultural and Economic Convergence in the EU Integration Process: Do Geographical Relationships Matter? [PDF]

open access: yes
In the light of the reaffirmed importance of agricultural convergence within the integration process, the paper provides a preliminary investigation of the impact of the enlargement from the EU-15 to the EU-27 on agricultural real b-convergence and, with

Local taxation in the EU: A convergence study

open access: yesInvestigaciones Regionales - Journal of Regional Research, 2019
In this note we study the convergence of local taxation in the EU-15 for 1975-2015 and two sub-periods, 1975-1994 and 1995-2015. Through a sigma convergence analysis, we find evidence of convergence for 1975-2015 and 1995-2015 but divergence for 1975-1994. In a club convergence approach, the countries are clustered into two clubs in the overall sample,

Investigating the Low‐Temperature Phase Stability of the Binary Ta–W System

open access: yesAdvanced Engineering Materials, EarlyView.
Atomistic simulations show that the binary Ta–W system forms ordered intermetallic phases, B2‐TaW and D03‐TaW3, as 0 K ground states. Configurational entropy, however, lowers the free energy of the disordered bcc solid solution, which becomes the stable phase above about 400 K.
