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 ...
An updated list of Serbian diatom flora – new recorded taxa
(Serbian Biological Society, 2018)
Diatoms are a widespread group of organisms with well-known ecological preferences. Knowledge of their diversity is of great importance for assessing the environmental status of different aquatic ecosystems. The present ...
The application of benthic diatoms in waterquality assessment (Mlava River, Serbia)
(University of Zagreb, 2016)
The main objective of this study was to assess the ecological status of the Mlava River based on
epilithic diatoms and to test the use of diatom indices as a tool for estimating the quality of fl owing waters in
Serbia. ...
Diatoms from a peat bog on the Pešter plateau (southwestern Serbia): New records for diatom flora of Serbia
(Institut za Bioloska Istrazivanja, 2015)
The distribution of diatoms was studied in three types of diatom communities (epiphytes, benthos and plankton)
of a peat bog on the Pešter plateau. The observed diatom flora inhabited all investigated communities, comprising ...
Linear Free Energy Relationships of the C-13 NMR chemical shifts in 5-(3-and 4-substituted arylazo)-4,6-dimethyl-3-cyano-2-pyridones
(Arkat USA Inc., 2009)
The C-13 NMR chemical shifts of the C2 carbon atom in the heteroaromatic nuclei of seventeen 5-(3- and 4-substituted arylazo)-4,6-dimethyl-3-cyano-2-pyridones were determined in deuterated DMSO solution. For quantitative ...
Construction and calibration of a portable rain simulator designed for the in situ research of soil resistance to erosion
(Prague : Czech Academy of Agricultural Sciences, 2022)
Land degradation caused by erosion processes is a widespread global problem. Rain simulators are one of the tools often used to determine the resistance of soils to erosion processes. The aim of this publication is to ...
Properties of aliphatic hyperbranched polyesters in diluted solutions
(Belgrade : Serbian Chemical Society, 2007)
The results of an investigation of the influence of the synthesis procedure,
number of pseudo generations and degree of branching of hydroxy-functional aliphatic hyperbranched polyesters (AHBP) on the values of limiting ...
Polianilinski tanki filmovi u senzorima za detekciju štetnih agenasa kod zavarivanja / Polyaniline thin films in sensors for detection of toxic welding vapors
(Belgrade: Association of the Chemical Engineers of Serbia, 2010)
In this paper the possibilities of applying sensors based on filters with surface acoustic waves (SAW) for the detection of harmful products in welding processes are analyzed. This review discusses the sensing mechanism ...
