Monolithic nanocrystalline SiC ceramics
(Elsevier Sci Ltd, Oxford, 2016)
Additive-free beta-SiC nanopowders were densified by using high-pressure "anvil-type with hollows" apparatus at the pressure of 4 GPa in the range of 1500-1900 degrees C. The starting powder with average particle size of ...
Optimization of Al2O3 particle modification and UHMWPE fiber oxidation of EVA based hybrid composites: Compatibility, morphological and mechanical properties
(Elsevier Sci Ltd, Oxford, 2018)
Ultra-high molecular weight polyethylene (UHMWPE, PE)/oxidized PE (ox-PE) fibers and alumina reinforcement were used in preparation of poly (ethylene-co-vinyl acetate) (EVA)/hydrolyzed EVA (EVAOH) based composites. Different ...
Optimized preparation of alumina based fillers for tuning composite properties
(Elsevier Sci Ltd, Oxford, 2018)
Alumina based particles were prepared from aluminium chloride hydroxide as starting material by sol-gel technique. One series of particles was doped with ferrous oxide. Both series of particles were calcinated at three ...
Mg/Cu co-substituted hydroxyapatite - Biocompatibility, mechanical properties and antimicrobial activity
(Elsevier Sci Ltd, Oxford, 2019)
The aim of this study was to improve the mechanical properties and to optimize antimicrobial activity of hydroxyapatite (HAP) by simultaneous doping with Mg and Cu ions in order to obtain material that would be able to ...
Composite materials from fully bio-based thermosetting resins and recycled waste poly(ethylene terephthalate)
(Elsevier Sci Ltd, Oxford, 2018)
During the last two decades, interest in bio-based polymers, especially in bio-based composite materials, has grown as a result of environmental concerns. In this paper new composites obtained from fully bio-based unsaturated ...
Aramid hybrid composite laminates reinforced with inorganic fullerene-like tungsten disulfide nanoparticles
(Elsevier Sci Ltd, Oxford, 2017)
Combination of phenolic resin with poly (vinyl butyral), PVB, is often used as impregnation of aramid fabrics in prepregs for the ballistic protection products. In this study an effect of inorganic fullerene-like tungsten ...
Initial microstructure effect on the mechanical properties of Ti-6Al-4V ELI alloy processed by high-pressure torsion
(Elsevier Science Sa, Lausanne, 2018)
effect of initial microstructure on the mechanical properties and fracture mode of the Ti-6Al-4V ELI alloy subjected to the high-pressure torsion (HPT) processing at room temperature and 500 degrees C was investigated. In ...
Tailoring the properties of waterborne polyurethanes by incorporating different content of poly(dimethylsiloxane)
(Progress in Organic Coatings, 2021)
A series of novel waterborne polyurethanes (WBPUs) was synthesized using alpha,omega-dihydroxypropyl poly(dimethylsiloxane) (PDMS), isophorone diisocyanate (IPDI), 2,2-bis-(hydroxymethyl) propionic acid (DMPA) and triethylamine ...
Nanoindentation study of nickel manganite ceramics obtained by a complex polymerization method
(Elsevier Sci Ltd, Oxford, 2016)
The chemical synthesis of nickel manganite powder was performed by a complex polymerization method (CPM). The obtained fine nanoscaled powders were uniaxially pressed and sintered at different temperatures: 1000-1200 degrees ...
Polyurethane networks based on polycaprolactone and hyperbranched polyester: Structural, thermal and mechanical investigation
(Elsevier Science Sa, Lausanne, 2019)
A series of environmentally friendly polyurethane (PU) networks based on polycaprolactone as soft segment (SS) and Boltorn (R) aliphatic hyperbranched polyester of the second pseudo generation as crosslinking agent was ...
