Flame retardant effect of aluminum hypophosphite in heteroatom-containing polymers
(Springer, 2020)
In the present study, the effect of the aluminum hypophosphite (AlHP) concentration on the flame retardant properties of the four different polymers [polyamide 6 (PA6), poly(lactic acid) PLA, thermoplastic polyurethane ...
A variable pole magnet
(Iop Publishing Ltd, 2018)
The off-stoichiometric antiferromagnetic Heusler alloy Fe50Mn45Ga5 decomposes and forms ferromagnetic Fe50Mn25Ga25 precipitates embedded in an antiferromagnetic Fe50Mn50 matrix when temper-annealed at temperatures T > 550 ...
Synthesis of Si3N4 using sepiolite and various sources of carbon
(Kluwer Academic Publ, 2001)
Sepiolite of Turkish origin was used as Si precursor in the syntheses of silicon nitride (Si3N4) powders by carbothermal reduction-nitridation (CRN) by mixing with several reducing agents i.e. charcoal, carbon black and ...
Room-temperature five-tesla coercivity of a rare-earth-free shell-ferromagnet
(American Institute of Physics Inc., 2017)
Ni2MnX-based Heusler (X: main group element), when enriched with Mn, will decompose into ferromagnetic Ni2MnX and antiferromagnetic NiMn when temper-annealed around 650 K. When the starting material is chosen such that the ...
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 ...
