Electrochemical behavior of acid activated clays
(Belgrade : Vinča Institute of Nuclear Sciences, 2014)
Smectites are phyllosilicates of 2:1 type, meaning that octahedral sheet in sandwiched between two tetrahedral sheets. Due to isomorphous substitutions (Al3+ or Fe3+ for tetrahedral Si4+ and Mg2+, Fe2+ or Fe3+ for octahedral ...
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 ...
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 ...
Study of possibilities of application of a thermopile-based gas sensor
(Belgrade : The Military Technical Institute, 2014)
The goal of this work is exploring the possibilities of application of a thermopile-based gas sensor. The main
task was to study for which kind of gases this type of sensor would be suitable. For this purpose self-developed ...
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 ...
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 ...
The role of hydrogeochemistry in defining geopathogenic zones of natural radionuclides influence in the living environment of rural settlements
(International Multidisciplinary Scientific Geoconference, 2014)
In accordance to geological-structural characteristics of the terrain, in the phase of regional researches of uranium, different methods of geochemical prospection were applied. By hydrogeochemical prospection areas of ...
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 ...
Leaching of Arsenic from Tailings by Microbially Produced Rhamnolipids
(Japan Society for Environmental Chemistry, 2014)
The focus of this study was to determine influence of microbial surfactants rhamnolipids on mobilization of heavy metals from the tailings and to estimate the use of rhamnolipids, as washing agents in pretreatment of metal ...
Analysis of refractory castables subjected to thermal shock by non-destructive methods
(Bor : University of Belgrade - Technical Faculty in Bor, 2014)
