Low‐Cost, Large‐Scale Nanoporous Metals by Mechanical Alloying, Oxide Reduction, and Dealloying of Powders

open access: yesAdvanced Engineering Materials, EarlyView.
Powder metal processing provides scalable advantages in nanoporous (np) metal development. Mechanical alloying is used to produce unique precursors for hybrid nanopore formation by oxide reduction and dealloying. As demonstrated in np Ag, this approach improves process efficiency while promoting smaller ligaments and larger pores, both of which are ...

The Southern Separatist Movement and the Civil War Years in Sudan, 1955-1972

open access: yesJournal of Universal History Studies
The diversity regarding the social construct of Sudan, co-ruled under Anglo-Egyptian Condominium, during the former half of 20th century led to remarkable crises with the administrative organisations commencing to be instituted during the process of ...

Innovative Processing of Compacted Waste Aluminum Alloy Powders via Controlled Remelting and Solidification

open access: yesAdvanced Engineering Materials, EarlyView.
This study demonstrates an efficient recycling route for out‐of‐spec AlSi10Mg atomized powders through compaction and arc remelting followed by suction casting. By correlating compaction load, cooling rate, and resulting microstructure, we show that intermediate pressures (50–80 kN) and rapid cooling refine dendrites, reduce porosity, and enhance ...

Interactions between Molten High‐Silicon Electrical Steels and Carbon‐Bonded MgO Refractories Based on Recyclates

open access: yesAdvanced Engineering Materials, EarlyView.
This study examines how several molten high‐silicon electrical steels interact with both conventional and recycled MgO–C refractories. For this, various immersion experiments are conducted. In addition to infiltration, a number of mechanisms are identified and explained that control the corrosion of the refractory material.

[Review of] Joseph Rothschild, Ethnopolitics, A Conceptual Framework [PDF]

open access: yes, 1982
Whether ethnicity stems from certain intrinsic group characteristics or whether it is a definition conferred upon various groups because of their political, social, and economic environment has been a fundamental debate within the field of ethnic studies.

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 ...

La Ligue du Nord : le retour ambigu de l’identité territoriale sur la scène politique italienne

open access: yesL'Espace Politique, 2011
The North League (Lega Nord) is now and for the third time in its short history part of a coalition government led by Silvio Berlusconi. Its political program advocates the transformation of Italy into a federal state with fiscal federalism for more ...
