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 ...
The effect of mechanical activation on synthesis and properties of MgAl2O4 ceramics
(Elsevier Sci Ltd, Oxford, 2019)
Magnesium aluminate, MgAl2O4 and other alumina-based spinels are ceramics with high hardness, high melting point and mechanical strenght. Spinels can also be used as dielectrics in microwave applications. The goal of this ...
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 ...
Preparation, characterization and mechanical properties of Bi12SiO20-PMMA composite films
(Elsevier Science Sa, Lausanne, 2014)
This paper investigates processing and characterization of polymer composite material PMMA-Bi12SiO20 (BSO). Thin films of pure PMMA and composites with 0.5 and 1.0 wt% of Bi12SiO20 powder were made using solution casting ...
Mg/Cu co-substituted hydroxyapatite – Biocompatibility, mechanical properties and antimicrobial activity
(Elsevier Ltd, 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 ...
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 ...
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 ...
alpha-Tricalcium phosphate/fluorapatite based composite cements: Synthesis, mechanical properties, and biocompatibility
(Elsevier Sci Ltd, Oxford, 2020)
Composite cements based on alpha-tricalcium phosphate (alpha-TCP) and nanostructured fluorapatite (FAp), alpha-TCP/FAp, appropriate for dental usage as root canal filling material, have been prepared with the improved ...
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 ...
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 ...
