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 ...
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 ...
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 ...
Estimation of elastic properties of a particulate polymer composite using a face-centered cubic FE model
(Elsevier, Amsterdam, 2004)
A three-dimensional (31)) finite element (FE) unit cell model is applied to studies on the elastic properties of ceramic spherical particle-polymer composite. In this model, hydroxyapatite particles (HAp) are assumed to ...
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 ...
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 ...
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) ...
Evaluation of the antibacterial effectiveness of novel copper/polypyrrole nanocomposite
(Elsevier B.V., 2023)
A novel and effective antibacterial agent based on a combination of copper nanoparticles (CuNPs) and polypyrrole (PPy) is presented. By using a straightforward in situ polymerization method in water, a copper/polypyrrole ...
Optical fibers with composite magnetic coating
(Elsevier, 2002)
The goal of these investigations was to define the process parameters that enable the formation of a composite coating with the most uniform thickness on an optical fiber. The composite coating was obtained by drawing the ...
Contribution to study of processes on the steel cast-sand mould contact surface during casting
(Elsevier Science B.V., 2000)
The testings involved in this paper were part of a comprehensive research project conducted to find out what complex processes were taking place at metal-mould contact surface. These investigations are of particular ...
