Conventional and spark-plasma sintering of cordierite powders synthesized by sol-gel methods
(Elsevier Sci Ltd, Oxford, 2013)
Cordierite powders synthesized by colloidal and alkoxide sol-gel methods were conventionally and spark-plasma sintered. The powders for the sintering investigations were obtained by calcination of the gels at a temperature ...
Investigation of silver impact on hydroxyapatite/lignin coatings electrodeposited on titanium
(Elsevier Science Sa, Lausanne, 2013)
Silver doped hydroxyapatite (HAP) [Ca9.95Ag0.05(PO4)(6)(OH)(2)] composite coatings with natural polymer organosolv lignin (Lig) were produced by electrophoretic deposition (EPD) on titanium. Coatings were characterized by ...
The effects of cytokinin types and their concentration on in vitro multiplication of sweet cherry rootstock Gisela 5 / Uticaj vrste i koncentracije citokinina na in vitro multiplikaciju podloge za trešnju Gisela 5
(Naučno voćarsko društvo Srbije, Čačak, 2014)
The most important aspect of successful micropropagation. Among other in vitro factors, is to use the optimal types and concentrations of plant growth regulators. With the aim of optimization of in vitro multiplication of ...
Microwave-assisted extraction for the recovery of antioxidants from waste Equisetum arvense
(Elsevier, Amsterdam, 2014)
Microwave-assisted extraction was optimised by the response surface methodology in order to enhance the extraction of polyphenols from Equisetum arvense (horsetail). Under the optimal conditions the total polyphenol content ...
Photocatalytic efficiency of titania photocatalysts in saline waters
(Srpsko hemijsko društvo, Beograd, 2014)
The photocatalytic efficiency of a recently synthesized TiO2 powder, denoted P160, for the degradation of the Dye C.I. Reactive Orange 16 in natural and artificial seawater was investigated in comparison to its efficiency ...
Hydro- and solvothermally-prepared ZnO and its catalytic effect on the photodegradation of Reactive Orange 16 dye
(Srpsko hemijsko društvo, Beograd, 2014)
In this work, zinc oxide powders were obtained by two different techniques: hydro- and solvothermal synthesis starting from Zn(NO3)(2) and Zn(CH3COO)(2), respectively. The influence of synthetic procedure on the structural, ...
Defining the ideality of the protective masks by the mathematical modeling method / Određivanje idealnosti zaštitnih maski metodom matematičkog modelovanja
(University of Belgrade - Faculty of Mechanical Engineering, Belgrade, 2019)
Technical contradiction occurs when the system improves one parameter, which automatically causes the deterioration of some of its other parameters. In such a situation, instead of usual acceptance of the optimization of ...
Modification of natural clinoptilolite for nitrate removal from aqueous media
(Srpsko hemijsko društvo, Beograd, 2014)
Natural zeolitic tuff from the Zlatokop mine (Vranjska Banja deposit, Serbia) was investigated as the starting material to obtain a low cost adsorbent for the removal of nitrate from aqueous media. The tuff rich in zeolite, ...
Ballistic Properties of Hybrid Thermoplastic Composites with Silica Nanoparticles
(Inda, Cary, 2014)
Multi-axial aramid fabrics have a wide range of applications in the construction of composite structures for body armor. Nanoparticles, which include nanosilica, are one of the most common nanofillers for these structures. ...
IR/Raman characterization of Au-mercaptotriazole crystals
(Bulgarian Academy of Sciences, 2019)
The aim of this study was a characterization of the crystals of gold complexes based on mercaptotrazole, obtained from solutions with different pH values (2, 4, 7, and 9), using the methods of infrared (IR) and Raman ...
