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 ...
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 ...
Metal ve seramik tozlarının bilgisayar kontrollü tek eksenli kalıpta preslenmesi
(1999)
This study is about the investigation of the mechanical properties of metal and ceramic powders pressed by a uniaxial die. The bronze powders have spherical particles, copper powders are of oval, iron powders are of porous ...
A study of compaction of metal powders
(1996)
This paper is a summary of an investigation of the compaction of metal powders. Two types of irregular atomized iron powders, a spherical copper powder and a bronze powder were uniaxially compacted in a floating-action die ...
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 ...
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 ...
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 ...
