Thermodynamic Pathways of Nonequilibrium Solidification in Wire‐Arc Additive Manufacturing Fe‐Based Multicomponent Alloy Structures

open access: yesAdvanced Engineering Materials, EarlyView.
Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Tailored Hierarchical Porous Copper Architectures via Three Dimensional Printing and Pressure‐less Sintering for Next‐Generation Lithium‐Metal Batteries

open access: yesAdvanced Engineering Materials, EarlyView.
A hierarchical porous copper current collector is fabricated via three‐dimensional printing combined with pressureless sintering to stabilize lithium metal anodes. The interconnected architecture lowers local current density, guides uniform Li deposition within pores, and suppresses dendrite growth.

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

open access: yesAdvanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Faits divers, faits littéraires. Le romancier contemporain devant les faits accomplis [PDF]

open access: yes, 2009
Si, dans la première moitié du XIXe siècle, la littérature a pu servir de fond commun aux « manières de raconter » le monde et imposer ainsi sa marque au discours journalistique naissant, aujourd’hui c’est au roman — dont la frange la plus exigeante, au ...

Composition‐Tuned Enhancement of the Anomalous Nernst Effect in FeCo–Pt Thin Films on Rigid and Flexible Substrates

open access: yesAdvanced Engineering Materials, EarlyView.
Disordered (Fe50Co50)1−xPtx thin films exhibit a pronounced anomalous Nernst effect (ANE) with a strong composition dependence on both rigid and flexible substrates. The transverse thermoelectric response peaks near 22.5 at.% Pt, accompanied by enhanced αxy/σxy scaling, thermal transport, and ANE sensitivity.

Approches critiques de la fiction afro-américaine

open access: yes, 1998
Ce recueil découle d’un symposium européen organisé conjointement par les Universités de Paris VII et de Tours en 1993. Un premier volume fut consacré à Toni Morrison, en particulierBeloved. Tardivement, mais toujours d’actualité, ce second volume aborde d’autres fictions et montre ainsi la richesse et la complexité de la production noire au nouveau ...

Young people viewing Hindi films: ideology, pleasure and meaning [PDF]

open access: yes, 2006
Despite or perhaps because of the continued popularity of Hindi films, it has often been assumed that audience responses can be read from box office takings or film texts.

Manacled to Identity: Cosmopolitanism, Class, and ‘The Culture Concept’ in Stephen Crane [PDF]

open access: yes, 2013
This article begins with a close reading of Stephen Crane’s short story ‘Manacled’ from 1900, which situates this rarely considered short work within the context of contemporary debates about realism.

On the Influence of Antioxidants and Recycled MgO–C Source Material on the Mechanical Properties of Carbon‐Bonded Magnesia Refractories

open access: yesAdvanced Engineering Materials, EarlyView.
The presented study focuses on the fracture behaviour of carbon‐bonded magnesia MgO–C refractories, where environmentally friendly fructose, collagen and lignin serve as temporary binding agents. The partial substitution of the source material with recycled MgO–C reduces the fracture resistance, which can be counteracted by the additional introduction ...

Lacking Capitalism: Desiring marketing in times of capitalist crisis [PDF]

open access: yes, 2008
In this paper we analyze the social and historical construction process of marketing, and how it is inherently linked to the reproduction of capitalism in times of crisis.
