The influence of the sintering regime on the stability of the SmCo5 phase
(Elsevier, Amsterdam, 1997)
The purpose of this investigation was to establish the correlation between the sintering conditions (temperature and time) and the stability of the SmCo5 phase, expressed by the intensity of its most important diffraction ...
Influence of formation conditions and precursor viscosity on mean fiber diameter formed using the relating disk method
(Elsevier, Amsterdam, 2000)
Alumina ceramic fibers were produced from aluminum-hydroxidechloride based sol. Polyvinyl alcohol and surface active material were applied to adjust the rheological characteristics of the: sol. The rotating disk formation ...
Interface shape and distribution of solute during Vertical Bridgman growth of Al-Cu alloy
(Elsevier, Amsterdam, 2002)
Results presented in this paper contribute to investigation of the influence of solidification rate (R) and the initial concentration of solute (C-o) on the interface shape and the distribution of the solute. Solidification ...
Novel biosensor films based on chitosan
(Elsevier Science Bv, Amsterdam, 2016)
Films of chitosan and poly(itaconic acid) in various different ratios have been prepared by membrane casting. The enhancement in the proton conductivity and uptake of water was observed as the content of poly(itaconic acid) ...
Thermal properties of PS/TiO2 nanocomposites obtained by in situ bulk radical polymerization of styrene
(Elsevier Science Bv, Amsterdam, 2009)
TiO2 nanoparticles. surface modified with 6-palmitate ascorbic acid, were incorporated in polystyrene (PS) by in situ bulk radical polymerization of styrene using 2,2'-azobisisobutyronitrile as initiator. The molar mass ...
Copper nanoparticles with high antimicrobial activity
(Elsevier Science Bv, Amsterdam, 2014)
Copper (Cu) hydrosol containing small nanoparticles (NPs) (similar to 5 nm) with narrow size distribution were used to investigate antimicrobial activity toward representative microorganisms of public concern (Escherichia ...
Silicon-doped biphasic alpha-calcium-phosphate/hydroxyapatite scaffolds obtained by a replica foam method using uniform pre-annealed spherical particles
(Elsevier Science Bv, Amsterdam, 2012)
In this study, spherical particles of hydroxyapatite (HA) and alpha-tricalcium phosphate (alpha-Ca-3(PO4)(2): alpha-TCP) doped with different amounts of silicon were used for the preparation of scaffolds. The scaffolds ...
Bimetallic alginate nanocomposites: New antimicrobial biomaterials for biomedical application
(Elsevier Science Bv, Amsterdam, 2018)
Two bimetallic (Zn/Cu) alginate based nanocomposites, impregnated with carbonate or phosphate mineral phase, were prepared by a facile procedure. Mineralized samples exhibited different morphologies and properties when ...
The implementation of image analysis for the visualization of adhesion assessment of a composite film
(Elsevier Science Bv, Amsterdam, 2018)
The objective of this study is to investigate quantitative assessment of the adhesion behavior of composite films onto a metallic surface. The composite films had UV cured Bis-GMA (Bisphenol A glycidylmethacrylate)/TEGDMA ...
Thermal shock behavior of alumina based refractories: fracture resistance parameters and water quench test
(Elsevier, Amsterdam, 1999)
The prediction of refractories thermal shock behavior can be estimated on two basis: heat transfer conditions and/or fracture mechanics concept. Materials considered in our analysis were alumina based refractories with ...
