Unusual Correlation between SKPFM and Corrosion of Nickel Aluminum Bronzes [PDF]

, 2017
Scanning Kelvin probe force microscopy was used to investigate the influence of microstructure on the corrosion behavior of nickel aluminum bronzes in ammoniacal and NaCl solutions as well as under potential control in Na2SO4.

The influence of recycling on the localized corrosion susceptibility of extruded AA6063 alloys

npj Materials Degradation
An approach involving the quantification of microstructure characterized by different techniques such as SEM, EDS, and SKPFM is statistically treated to provide a deeper insight into the influence of recycling AA6063 on localized corrosion susceptibility.

Controlled ageing-induced nano Gd precipitation: An effective strategy to improve mechanical, corrosion, antibacterial and biocompatibility of Mg-0.5Mn-7.3Gd alloy

Journal of Magnesium and Alloys
Magnesium alloys have long been recognized as promising degradable biomaterials, however, bacterial infection, poor mechanical and corrosion properties limit its clinical application.

Between Dispossession and Inclusion: Land Injustice and Project‐Based Citizenship in the Bagré Irrigation Scheme (Burkina Faso)

Journal of Agrarian Change, EarlyView.
ABSTRACT Large‐scale irrigation schemes are central to agrarian transformation in sub‐Saharan Africa, yet their political implications are often reduced to questions of land redistribution or agrarian differentiation. Although existing scholarship has documented how irrigation restructures agrarian relations and generates dispossession, less attention ...

Improving wear and corrosion resistances of Mg2Si/AZ91 composites via tailoring microstructure and intrinsic properties of Mg2Si induced by Sb modification

Journal of Magnesium and Alloys
To achieve simultaneous improvement in wear resistance and corrosion resistance, we propose a novel strategy to successfully develop Mg matrix composites containing blocky primary Mg2Si with small size instead of undesirable dendrite shape and large size.

Local Solutions to Structural Issues: The Fetishization of Custom in Rural Development Interventions in Côte d'Ivoire

Journal of Agrarian Change, EarlyView.
ABSTRACT This paper explores the paradox of seeking local solutions in rural development when conflicts result from structural transformations of the agrarian economy driven by national political choices. Since the 1990s, participatory approaches inspired by neo‐institutionalist theories of local governance have encouraged development actors to view ...

Effect of Y addition on microstructure, tensile properties, and corrosion behavior of high-speed-extruded Mg–5Bi–3Al alloy

Journal of Magnesium and Alloys
This study investigates the effect of Y addition on the microstructure, tensile properties, and corrosion behavior of high-speed-extruded Mg–5Bi–3Al (BA53) alloy. Y-free BA53 and Y-containing BAW53 x alloys ( x = 0.2, 0.5, and 1.0 wt.%) are extruded at a

Remembering Independence, Debating the Nation: Ghana's National Days

Nations and Nationalism, EarlyView.
ABSTRACT In Ghana, Independence Day is the most important national day and has been annually observed since the attainment of independence in 1957. Additional national days that various military governments introduced to commemorate their ascension to power have been rather short‐lived. Other holidays like Republic Day or Founder's Day have been longer

Stability and change in the distribution of cytospecies of the Simulium damnosum complex (Diptera: Simuliidae) in southern Ghana from 1971 to 2011. [PDF]

, 2013
BACKGROUND: Simulium damnosum s.l., the most important vector of onchocerciasis in Africa, is a complex of sibling species that have been described on the basis of differences in their larval polytene chromosomes.
