Computer-assisted teaching and assessment of disabled students in higher education: the interface between academic standards and disability rights
(Blackwell Publishing, 2007)
Computer-assisted teaching and assessment has become a regular feature across many areas of the curriculum in higher education courses around the world in recent years. This development has resulted in the 'digital divide' ...
Decomposition in Ni-Co-Mn-In functional Hensler alloys and its effect on shell-ferromagnetic and magnetocaloric effects
(Amer Physical Soc, 2020)
Ni-Co-Mn-In Heusler-based compounds are interesting for their magnetocaloric properties and have been widely investigated for this purpose. For Co compositions more than 5 at% in (Ni100-xCox)(50)Mn25+yIn25-y the material ...
Segregation Resistant Nanocrystalline/Amorphous (La, Sr) CoO3-(La,Sr)(2)CoO4 Composite Cathodes for IT-SOFCs
(Electrochemical Soc Inc, 2019)
There is a considerable interest in lowering the operating temperature of solid oxide fuel cells. In this respect, (La,Sr)CoO3(La,Sr)(2)CoO4 dual phase oxides have attracted much attention as cathode materials due to their ...
Water Impact Resistant and Antireflective Superhydrophobic Surfaces Fabricated by Spray Coating of Nanoparticles: Interface Engineering via End-Grafted Polymers
(Amer Chemical Soc, 2018)
Fully transparent and water impact resistant superhydrophobic coatings are of great importance for a range of applications including photovoltaics, photonics, automotive windshields, and building windows. A widely utilized ...
Evolution of Microstructure and Texture in AZ31 Alloy Subjected to Gas Forming
(Springer, 2017)
In this study, AZ31 sheets were subjected to gas forming using a stepped geometry die and employing two different temperatures (400A degrees C and 450A degrees C) and exposure times (60 s and 120 s). Microstructural ...
Ab initio Prediction of Martensitic and Intermartensitic Phase Boundaries in Ni-Mn-Ga
(Amer Physical Soc, 2016)
Despite the importance of martensitic transformations of Ni-Mn-Ga Heusler alloys for their magneto-caloric and shape-memory properties, the martensitic part of their phase diagrams is not well determined. Using an ab initio ...
Segregation tendency of Hensler alloys
(Amer Physical Soc, 2019)
Segregation in a series of Ni2Mn1+x(In, Sn, Ga, Al)(1-x) and Mn2Ni1+x(Ga, Al) as well as Ni2+xMn1-xGa Heusler alloys is studied by first-principles calculations. We show that Mn-rich Ni2Mn1+x(In, Sn, Al)(1-x) compounds are ...
A Review on Developments in Magnesium Alloys
(Frontiers Media Sa, 2020)
In order to facilitate the understanding of the current research efforts and directions, this article first introduces the anomalous/problematic features of magnesium (Mg) and presents the recent approach of stacking fault ...
Continuous synthesis of graphite with tunable interlayer distance
(Elsevier Science Sa, 2019)
A study was carried out to produce graphite with controlled interlayer distance synthesized from methane using hydrogen as modifying agent. The synthesis was carried out in radio frequency (r.f.) thermal plasma where the ...
Effect of Al doping on the magnetic and elastic properties of Fe65Ni35 Invar alloys
(Scientific Technical Research Council Turkey-Tubitak, 2019)
Invar alloys have great importance due to their low thermal expansion coefficient. The effect of Al doping on Fe65Ni35 Invar alloy was investigated by temperature-dependent magnetization and elastic modulus measurements. ...
