Magnetic and structural instabilities in mictomagnetic Cu50Mn45Al5 against the formation of ferromagnetic precipitates
(Pergamon-Elsevier Science Ltd, 2020)
A new property of Heusler alloys known as shell-ferromagnetism is observed predominantly in NiMn-based Heusler alloys with X as Ga, Al, In and Sn. An antiferromagnetic-matrix/shell-ferromagnetic precipitate dual-phase ...
The flame-retardant effect of calcium hypophosphite in various thermoplastic polymers
(Wiley, 2019)
The flame-retardant behavior of calcium hypophosphite (CaHP) was investigated in different thermoplastic polymers including polyamide 6 (PA), poly (lactic acid) (PLA), thermoplastic polyurethane (TPU), and poly methyl ...
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' ...
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 ...
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 ...
