Enhanced antimicrobial efficacy by co-delivery of PGA capped silver nanoparticles and ascorbic acid with poly(lactide-co-glycolide)
(Belgrade : Materials Research Society of Serbia, 2012)
Silver nanoparticles (AgNps) were prepared by modified chemical reduction with poly (Lglutamic acid) (PGA) as capping agent. These Ag/PGA nanoparticles (AgNpPGAs) were highly stable over the long periods of time without ...
Mechanochemically Synthesized CaO ZnO Catalyst For Biodiesel Production
(Elsevier, 2012)
The transesterification of triglycerides (vegetable oil) with methanol using CaO·ZnO mixed oxides catalyst were conducted to produce FAME (Fatty Acid Methyl Esters, i.e. biodiesel). Catalyst was synthesized by ball milling ...
Structural characterization and electrical properties of sintered magnesium-titanate ceramics
(Belgrade : Materials Research Society of Serbia, 2012)
In this article the influence of ball milling process on structure of MgO-TiO2 system, along with its influence on electrical properties of post-sintering samples, were investigated. Mixtures of MgO-TiO2 powders were ...
Multifunctional nano scale drug delivery particles based on vitamin D3-loaded hydroxyapatite in bone tissue engineering
(Belgrade : Materials Research Society of Serbia, 2012)
Specific group of controlled drug delivery systems in bone tissue engineering are multifunctional nanoparticle systems (MNPs) based on hydroxyapatite coated with drug loadedbioresorbable polymer. This study illustrates the ...
Structural and magnetic properties of mechanochemically synthesized nanocrystalline titanium monoxide
(Belgrade : Association of the Chemical Engineers of Serbia, 2012)
Nano-sized titanium monoxide (TiO) powder was prepared by mechanochemical synthesis. A mixture of commercial Ti and TiO2 (rutile) powders with the molar ratio of 1:1 was milled in a planetary ball mill for 5, 10, 20, 30 ...
Electrochemical characteristics of polyaniline/lead-dioxide power source
(Hunedoara : University Politehnica Timisoara, Faculty of Engineering Hunedoara, 2012)
Polyaniline (PANI) anode, electrochemically formed on graphite from aniline containing sulfuric acid solution, and electrochemically formed thin film lead dioxide cathode, were investigated for possible applications as ...
Controlled hydrothermal processing of ZnO powders in the presence of PVP
(Belgrade : Society of Physical Chemists of Serbia, 2012)
In this study low-temperature hydrothermal processing was used for synthesis of ZnO powders with controlled morphology, from micro rods, via hexagonal prism-like to nano-spheres, by varying [Zn2+]/[OH-] molar ratio. The ...
Determination of Particle Size Distributions by Laser Diffraction
(Beograd : Savez inženjera i tehničara Srbije, 2012)
The paper deals with the main principles of determination of particle size distribution using Mastersizer 2000, Malvern Instruments Ltd., UK. On the example of several problems we have demonstrated that the method is not ...
Evaluación de las propiedades luminiscentes y detección de Eu2+ en partículas nanoestructuradas del sistema Gd2-xEuxO3 (x= 0.05, 0.10 y 0.30)
(Madrid : Sociedad Espanola de Ceramica y Vidrio, 2012)
Mediante el método de Spray Pirólisis (SP) operando a 700ºC y en atmósfera de aire seco, se obtuvieron partículas nanoestructuradas de composición Gd2-xEuxO3 (χ= 0.05, 0.10 y 0.30) partiendo de las respectivas disoluciones ...
The optical properties of dopamine-TiO2 submicronic sized particles
(Belgrade : Agencija FORMAT, 2012)
It is highly desirable to induce significant red-shift in the optical absorption edges of TiO2 phases so that this class of low-cost and environmentally friendly materials can be used as effective optical absorbing materials ...
