Influence of different iron powders on the friction properties of sintered friction materials based on iron
(Elsevier Science B.V., 2000)
The possibility of using iron powders of different morphological, chemical and physical properties as the bases of the metal matrix of the friction layer in sintered friction materials for dry friction under severe braking ...
Suitability of TiO2 nanoparticles and prolate nanospheroids for laser desorption/ionization mass spectrometric characterization of bipyridine-containing complexes
(Elsevier Science Bv, Amsterdam, 2015)
Nanostructured materials as substrates for surface-assisted laser desorption and ionization time-of-flight mass spectrometry have two main advantages such as small number of signals in the low mass range and salt tolerance. ...
Chitosan-triclosan films for potential use as bio-antimicrobial bags in healthcare sector
(Elsevier, Amsterdam, 2017)
In this work, antimicrobial bioinspired films made from chitosan incorporated with triclosan were investigated. The tensile strenght of these films were in the range of 33 and 39 MPa, which presented satisfied mechanical ...
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 ...
Quantification of deformation response at cyclic compression of polymer fibrous systems
(Elsevier Science Bv, Amsterdam, 2014)
The difficulty in qualitative evaluation of deformation properties of polymer fibrous assemblies lies in the fact that these materials differ from materials such as wood, concrete, steel, etc., as a consequence of the ...
Ultra-high pressure densification and properties of nanostructured SiC
(Elsevier Science Bv, Amsterdam, 2016)
Cubic SiC nano-powder particles were synthesized by a sal-gel process with an average grains size of 9.5 nm which were subsequently densified by using a high-pressure "anvil-type with hollows" apparatus at a pressure of 4 ...
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 ...
The innovative combined microwave-assisted and photo-polymerization technique for synthesis of the novel degradable hydroxyethyl (meth)acrylate/gelatin based scaffolds
(Elsevier Science Bv, Amsterdam, 2018)
The discovery of novel biodegradable biomaterials able to support and control cellular activity as well as development of an enhanced and efficient method for their fabrication, are of paramount importance in the field of ...
Influence of different concentrations of Zn-carbonate phase on physical-chemical properties of antimicrobial agar composite films
(Elsevier, Amsterdam, 2019)
Agar-based composites with different Zn-carbonate mineral phase content were prepared by in situ mineralization and the solvent casting method. The mineral phase within the composite films was identified as hydrozincite, ...
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 ...
