The Morphological Characterization of Mechanically Activated ZnO Powder
(Belgrade : Serbian Ceramic Society, 2014)
The authors investigated the morphological characteristics of mechanically activated ZnO powder. ZnO powder was mechanically activated for 2, 5, 10 and 30 minutes in a planetary ball mill. Mechanical activation introduces ...
Selectivity issues in affinity-based biochemical sensors: Determining the ratio of similar biomolecules in binary mixtures
(Beograd : Društvo za ETRAN / Belgrade : ETRAN Society, 2014)
We consider selectivity of affinity-based nanosensors utilizing resonance shift due to the presence of adsorbed analyte. Among such devices we analyze mass-based sensors utilizing mechanical resonance in e.g. micro ...
Wet isotropic chemical etching of Pyrex glass with masking layers Cr/Au
(Beograd : Društvo za ETRAN / Belgrade : ETRAN Society, 2014)
In this paper we developed various techniques of wet isotropic chemical etching of Pyrex glass in an aqueous solution of 49% HF. The techniques are based on the processes of sputtering and photolithography. The various ...
Analysis of acoustic cloaks for anti-sonar camouflage based on local resonance in acoustic metamaterials
(Belgrade : The Military Technical Institute, 2014)
Non-visual camouflage plays a significant role in the art of military deception. One of the fields of interest is auditory camouflage, where the goal is to remove the acoustic signature of an object, whether it is generated ...
Synthesis of pullulan-based silver nanoparticles and their antimicrobial activity for prevention of food spoilage
(Macedonian Medical AssociationMacedonian Microbiological AssociationInstitute of Microbilogy and Parasitology, Medical Faculty, Scopje, 2014)
The aim of the present work was the synthesis of silver nanoparticles based on periodate oxidazed pullulan and investigation thus obtained material as an antibacterial agent.
In vitro antioxidant activity of levan produced by Brachybacterium sp. CH-KOV3
(Macedonian Medical AssociationMacedonian Microbiological AssociationInstitute of Microbilogy and Parasitology, Medical Faculty, Scopje, 2014)
In this work levan isolated from microorganism Brachybacterium paraconglorneraium
and fragments obtained by partial hydrolysis of purified polysacharide were evaluated by antioxidant activity. Levans (fructans) are ...
Hydrogeochemical characteristics of volcanoclastic sediment complex and impact of natural radionuclides on the environment of vranjska spa
(International Multidisciplinary Scientific Geoconference, 2014)
Based on the results of Aerogamma spectrometric examination of morphological and geological-structural analysis, for explore the content of natural radionuclides in groundwater and surface water, the basin of Vranje area ...
Assessment of sulfur-polymer composite quality based on nondestructive testing
(Bor : University of Belgrade - Technical Faculty in Bor, 2014)
In order to assess quality of sulfur-polymer composite, the samples were subjected to the induced destruction using hydrochloric acid solution. The image analysis technique was used for surface destruction monitoring. The ...
Oxygen Reduction on Palladium Modified Zeolite 13X
(Serbian Ceramic Society, 2014)
Palladium was dispersed over zeolite NaX by procedure of impregnation/thermal degradation of palladium acetylacetonate salt.
Samples characterization was performed by X-ray diffraction and SEM analysis. XR D analysis ...
Water quality degradation in the reservoir „grliste“as a result of inadequate implementation of sanitary protection zone
(International Multidisciplinary Scientific Geoconference, 2014)
Lakes and reservoirs, except groundwater and surface water, are in use for water supplying. In most cases, the reservoir was considered as a physical object from the hydroconstrucional and hydrogeological aspects and the ...
