Hydrogen Evolution on Zeolite Supported Platinum Clusters
(Wiley-VCH, 2003)
NaX type zeolite was loaded with platinum, by the thermal decomposition of Pt(II) acetylacetonate, up to the Pt/NaX mass ratio 0.174. The sample, dispersed on a glassy carbon rotating disc, was used in slightly acidic ...
Kvalitet podzemnih voda u području Zapadnobačkog okruga / The Quality of Underground qaters in the Region of West Bačka
(Beograd (Serbia): Udruzenje za tehnologiju vode i sanitarno inzenjerstvo, 2007)
The population and the industry in the region of West Backa are supplied with underground water which is specific in its quality due to higher content of organic substance, higher pH values, the presence of hydrogen-sulphide ...
The chemical characteristics of soil which determine phosphorus partitioning in highly calcareous soils / Hemijske karakteristike visoko-krečnjačkih zemljišta koje određuju raspodelu fosfora
(Serbian Chemical Society, 2006)
Phosphorus fractions from three highly calcareous soils (average, 24.9 ± 4.8 %CO3 2-) from sampling sites with a Mediterranean climate were isolated by sequential extraction. In order to provide a more reliable basis for ...
Analysis of design and installation thermocouples in power plants / Analiza izrade i ugradnje termoparova u elektroenergetskim postrojenjima
(Tehnika - Mašinstvo, 2009)
Measurement of temperature, in addition to pressure, is the most common type of measurement in the process industry and power plants. Thermocouples are most common in contact with devices. The selection and quality of final ...
Supercapacitive characteristics of electrochemically active porous materials / Superkondenzatorske karakteristike elektrohemijski aktivnih poroznih materijala
(Serbian Chemical Society, 2008)
The results of an investigation of the capacitive characteristics of sol-gel-processed titanium- and carbon-supported electrochemically active noble metal oxides, as representatives of porous electrode materials, are ...
Synthesis of a steroidal dendrimer core / Sinteza dendrimerskog steroidnog jezgra
(Belgrade : Serbian Chemical Society, 2004)
Synthesis of a steroidal dendrimercore possessing various functional termini, such as ester, carboxy and hydroxy, is presented. The approach described enables further simple manipulations for the introduction of more complex ...
Chemical modification of the lectin of the marine coral Gerardia savaglia by marine quinone avarone / Hemijske modifikacije lektina morskog korala Gerardia savaglia morskim hinonom avaronom
(Serbian Chemical Soc, Belgrade, 2007)
The quinone avarone, isolated from the marine sponge Dysidea avara, possesses the ability to chemically modify proteins. In this work, modification of lectin isolated from the coral Gerardia savaglia by avarone was examined. ...
7, 8, 15, 16-Tetraoxa-dispiro [5. 2. 5. 2]hexadecane-3-carboxylic acid derivatives and their antimalarial activity / Antimalarijska aktivnost derivata 7,8,15,16-tetraoksa-dispiro5.2.5.2heksadekan-3-karboksilne kiseline
(Serbian Chemical Society, 2004)
Several C2 symmetrical mixed tetraoxanes were prepared starting from a gemdihydroperoxide and a ketone. The obtained tetraoxanes showed pronounced antimalarial activity against P. falciparum chloroquine resistant W2 and ...
Adhesion of epoxy cataphoretic coatings on Zn alloys / Адхезија епоксидних катафоретских превлака на легурама цинка
(Belgrade : Serbian Chemical Society, 2007)
One of the most important factors in corrosion prevention by protective coatings is the loss of coating adhesion under environmental influence. In this work, the adhesion of epoxy cataphoretic coatings was examined on steel ...
Ethyl 3-(6-phenyl-44-1,2-dithiolo[1,5-b][1,2,4]dithiazol-2-yl) propanoate
(International Union of Crystallography, 2008)
The title compound, C15H15NO2S3, exists in a bicyclic form, with resonance contributions from two monocyclic forms, each without a second S - S bond. The trithiapentalene heterocyclic ring system is planar, with a mean ...
