Antimicrobial Titanium–Copper Alloys: The Role of Microstructure in Arc‐Melted Compositions

open access: yesAdvanced Engineering Materials, EarlyView.
Copper‐containing titanium alloys show promise in combating orthopedic implant infections. This study explores the influence of heat treatment on Ti‐11.5Cu and Ti‐33Cu alloys, revealing that larger Ti2Cu precipitates (≈5 μm) enhance antimicrobial efficacy through increased surface contact. Results suggest contact sterilization is the primary mechanism,

A Vascularized Microphysiological System Reproducing Endochondral Ossification in Vitro to Study Ewing Sarcoma Proliferation and Migration

open access: yesAdvanced Functional Materials, EarlyView.
A biofabricated 3D in vitro model recapitulating endochondral ossification (ECO) is described, mimicking the steps from condensation to chondrogenesis and hypertrophy, culminating with vascularization of the hypertrophic construct. As a model proof of concept application, Ewing Sarcoma cells are seeded in the model, showing modifications in their ...

Language and argumentation in the controversy economic [PDF]

open access: yes
This article offers an approach to the general structure of the controversy in economy. In our case we adopted a perspective to study a particular aspect of the rhetoric that comes from the context of a particular controversy: the controversy on the ...

What argumentation (theory) can do for philosophy in the 21st century [PDF]

open access: yes, 2013
The author holds that the old theory according to which philosophy is the matrix of argumentation studies must be entirely reviewed currently. He argues that argumentation theory, as an interdisciplinary domain, may start playing, in new terms, the role ...

A Theory of Philosophical Arguments

open access: yes, 2020
In this article, a new, idealizing-hermeneutic methodological approach to developing a theory of philosophical arguments is presented and carried out. The basis for this is a theory of ideal philosophical theory types developed from the analysis of historical examples. According to this theory, the following ideal types of theory exist in philosophy: 1.

Understanding and Optimizing Li Substitution in P2‐Type Sodium Layered Oxides for Sodium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
This work explores Li‐substituted P2 layered oxides for Na‐ion batteries by crystallographic and electrochemical studies. The effect of lithium on superstructure orderings, on phase transitions during synthesis and electrochemical cycling and on the interplay of O‐ versus TM‐redox is revealed via various advanced techniques, including semi‐simultaneous

Information Seeking Processes in Evaluating Argumentation [PDF]

open access: yes, 2007
This article points out the relevance of the research on information seeking for argumentation theory. The process of evaluating argumentation presupposes diverse principles of argument classification and forms thus conflicting information needs ...
