Microstructure and mechanical properties of Al-4·4 wt-%Mg alloy (AA5182) after equal channel angular pressing
(Maney Publishing, 2005)
Equal channel angular pressing (ECAP) has been used to process an Al-4-4 wt-%Mg alloy (AA5182) at room temperature (RT), 200°C and 400°C. The evolution of microstructure and mechanical properties after ECAP has been studied ...
Improvement of the mechanical properties of paper by starch coatings modified with sepiolite nanoparticles
(Wiley-VCH Verlag Gmbh, Weinheim, 2015)
The modern and rapidly developing paper and board industry requires more efficient agents for the surface of paper in order to improve the mechanical properties. The starch coating used for the reinforcement of schrenz ...
Improvement of mechanical properties and antibacterial activity of crosslinked electrospun chitosan/poly (ethylene oxide) nanofibers
(Elsevier Sci Ltd, Oxford, 2017)
In this study conditions for green crosslinking with citric acid of chitosan/PEO (polyethylene oxide) nanofibers were evaluated. The thermal in situ crosslinking enabled penetration of crosslinking agent into the matrix ...
Dual responsive antibacterial Ag-poly(N-isopropylacrylamide/itaconic acid) hydrogel nanocomposites synthesized by gamma irradiation
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
Thermo- and pH-sensitive Ag-P(NiPAAm/IA) hydrogel nanocomposites were prepared by in situ reduction of Ag+ ions with gamma irradiation. P(NiPAAm/IA) copolymer hydrogel matrices have been previously synthesized by radiation ...
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 ...
Bioactive hydroxyapatite/graphene composite coating and its corrosion stability in simulated body fluid
(Elsevier Science Sa, Lausanne, 2015)
The hydroxyapatite/graphene (HAP/Gr) composite was electrodeposited on Ti using the electrophoretic deposition process to obtain uniform bioactive coating with improved mechanical strength and favorable corrosion stability ...
The effect of graphene loading on mechanical, thermal and biological properties of poly(vinyl alcohol)/graphene nanocomposites
(Elsevier Science Inc, New York, 2016)
Poly(vinyl alcohol)/graphene (PVA/Gr) nanocomposite was synthesized with the aim of developing a novel improved material. The PVA/Gr nanocomposite was characterized by UV-visible spectroscopy, cyclic voltammetry, Raman ...
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 ...
New composites based on waste PET and non-metallic fraction from waste printed circuit boards: Mechanical and thermal properties
(Elsevier Sci Ltd, Oxford, 2017)
Influence of the addition of three different non-metallic fractions (NMF), obtained by processing of printed circuit boards (PCBs), on the mechanical and thermal properties of unsaturated polyester resin (UPR) based ...
