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, ...
In Vitro and In Vivo Biocompatibility of Novel Zwitterionic Poly(Beta Amino)Ester Hydrogels Based on Diacrylate and Glycine for Site-Specific Controlled Drug Release
(Wiley-VCH Verlag Gmbh, Weinheim, 2019)
New (beta-aminoester) hydrogels (PBAE) based on di(ethylene glycol)diacrylate and glycine are successfully synthesized and characterized for the first time in this work. PBAE macromers are obtained using Michael addition. ...
Broad Spectrum of Antimicrobial Activity of Cotton Fabric Modified with Oxalic Acid and CuO/Cu2O Nanoparticles
(Korean Fiber Soc, Seoul, 2019)
This study discusses the possibility of fabrication of textile nanocomposites with antimicrobial activity against antibiotics-resistant bacterial strains and yeast. Modification of cotton fabric with oxalic acid solutions ...
Biodegradation of cotton fabric impregnated with TiO2 nanoparticles
(Srpsko hemijsko društvo, Beograd, 2019)
Commercial P25 TiO2 nanoparticles are widely exploited as an efficient photocatalyst. In the textile domain, these nanoparticles are used for the production of self-cleaning, highly UV protective textiles, with an antimicrobial ...
Preparation and characterization of oxidized wheat starch with hydrogen peroxide as an environmentally friendly oxidant
(7th Conference of the Young Chemists of Serbia, 2019)
The starch oxidation involves oxidation of primary or secondary hydroxyl to carbonyl
or carboxyl groups, whereas the number of these groups indicates the level of oxidation.
Oxidized starch is used as surface sizing agent ...
The influence of Mg and Mn content on abnormal grain growth in AA5182 type alloys
(Savez inženjera metalurgije Srbije, Beograd, 2019)
The occurrence of abnormal grain growth (AGG) in AA5182 alloy during annealing imposes severe restrictions on processing parameters and deteriorates mechanical properties. In this work, we investigated the effect of chemical ...
Tailoring the physico-chemical and antimicrobial properties of agar-based films by in situ formation of Cu-mineral phase
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
New agar-based composite films with increasing Cu-carbonate and Cu-phosphate mineral phase content were prepared by in situ mineralization and solvent casting method. SEM and optical analysis revealed that Cu-carbonate ...
Leaching of toxic elements from secondary alkaline lead slag and stabilized/solidified products
(Springer, New York, 2019)
Secondary alkaline lead slag (SALS), generated during lead-acid batteries recycling, is a hazardous waste due to its high reactivity, solubility, and migration of toxic elements. After pulverization caused by storage under ...
Non-thermal plasma and ultrasound-assisted open lactic acid fermentation of distillery stillage
(Springer Heidelberg, Heidelberg, 2019)
Stillage is the main by-product of bioethanol production and the cost of its treatment significantly affects the economy of bioethanol production. A process of thermal sterilization before lactic acid fermentation (LAF) ...
Mg/Cu co-substituted hydroxyapatite - Biocompatibility, mechanical properties and antimicrobial activity
(Elsevier Sci Ltd, Oxford, 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 ...
