Polymers based on renewable raw materials - Part II / Polimeri na bazi obnovljivih sirovina – II. dio
(Croatian Society of Chemical Engineers, 2013)
A short review of biopolymers based on starch (starch derivatives, thermoplastic starch), lignin and hemicelluloses, chitin (chitosan) and products obtained by degradation of starch and other polysaccharides and sugars ...
Properties of quenched LiFePO4/C powder obtained via cellulose matrix-assisted method
(Powder Technology, 2013)
In this study, nanocrystalline LiFePO4/C composite powder has been synthesized via a cellulose matrix-assisted method. In an experiment conducted under extreme conditions involving rapid heating, short high-temperature ...
Radiation synthesis, characterisation and antimicrobial application of novel copolymeric silver/poly(2-hydroxyethyl methacrylate/itaconic acid) nanocomposite hydrogels
(Polymer Bulletin, 2013)
Silver nanoparticles were fabricated via in situ reduction of silver nitrate embedded in swollen P(HEMA/IA) hydrogel, using gamma radiolysis method. Copolymeric hydrogels based on 2-hydroxyethyl methacrylate (HEMA) and ...
Prediction and fuzzy synthetic optimization of process parameters in heavy clay brick production
(Elsevier Sci Ltd, Oxford, 2013)
Many factors influence final clay brick properties, since the raw materials used are highly heterogeneous. Statistical analysis is rarely used, according to literature, but it would improve understanding of the overall ...
The effect of yarn folding on some comfort properties / Efekat končanja pređa na neka svojstva komfora
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2013)
The compressive nature of textile fabrics is known to be a significant factor influencing tactile comfort. In addition, the transport of the heat through the fabric is considered to be the major factor in thermal comfort. ...
Transparent PMMA/silica nanocomposites containing silica nanoparticles coating under supercritical conditions
(Elsevier Science Sa, Lausanne, 2013)
This work reports the preparation of PMMA/silica nanocomposites with high optical transparency and enhanced mechanical properties using a melt compounding method. The surface of SiO2 particles was modified with a ...
Effect of welded joint imperfection on the integrity of pipe elbows subjected to internal pressure
(University of Osijek, Tech Fac, Slavonski Brod, 2013)
Since local defects reduce the load-carrying capacity and deformation ability of a piping system, an analysis is undertaken to quantify the influence of weld defects on integrity of the pipe elbows subjected to internal ...
Antimicrobial viscose fabric prepared by treatment in DBD and subsequent deposition of silver and copper ions-Investigation of plasma aging effect
(Elsevier Science Sa, Lausanne, 2013)
In this work, the effect of dielectric barrier discharge (DBD) in ambient air on preparation of antimicrobial viscose fabric was studied. DBD plasma treatment was applied under constant discharge power and different exposure ...
Mathematical modeling of cross-linking monomer elution from resin-based dental composites
(Wiley-Blackwell, Hoboken, 2013)
Elution of potentially toxic substances, including monomers, from resin-based dental composites may affect the biocompatibility of these materials in clinical conditions. In addition to the amounts of eluted monomers, ...
