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 ...
Chemical secretion and morpho-histology of the pygidial glands in two Palaearctic predatory ground beetle species: Carabus (Tomocarabus) convexus and C. (Procrustes) coriaceus (Coleoptera: Carabidae)
(Taylor & Francis Ltd, Abingdon, 2017)
Although all ground beetles have pygidial glands homologous in structure and function, there are many differences among species, often significant, in terms of chemical composition of the secretion and morphology of the ...
Gamma irradiation effects in optical fibres, splitters, and connectors / Efekti gama zračenja na optička vlakna, račve i konektore
(Vinča Institute of Nuclear Sciences, 2017)
The paper presents a brief overview of contemporary ELION techniques with stress on their use for material modification and dozimetry. In the attempt to avoid some common misjudges of irradiation effects, special attention ...
Analiza praga oštećenja bakra i aluminijuma u interakciji sa rubinskim laserom / The analysis of damage threshold in ruby laser interaction with copper and aluminium
(Association of Chemical Engineers of Serbia, 2010)
U radu su prikazani rezultati delovanja laserske svetlosti, talasne dužine λ = 694,3 nm (rubinski laser, Q-switch mod), na uzorke od bakra i aluminijuma. Cilj ispitivanja je bio da se odrede maksimalne gustine energije ...
Removal of heavy metals from water using multistage functionalized multiwall carbon nanotubes
(Serbian Chemical Society, 2017)
The multistage synthesis of the multi-wall carbon nanotubes (MWCNT) modified with polyamidoamine dendrimers, A1/and A2/MWCNT, capable of cation removal, is presented in this work, as well as novel adsorbents based on these ...
The effect of the structure of mixed tetraoxanes on their chromatographic behavior on different adsorbents
(Research Inst Medicinal Plants, Budakalasz, 2004)
The retention behavior of 29 biologically active compounds, mixed 1,2,4,5-tetraoxanes, has been investigated by thin-layer chromatography on unmodified silica, CN-silica, and RP-18-silica. The binary mobile phases ethyl ...
Effective Temperature Based Algorithm for Achieving Constant Quality Resistance Seam Weld
(Belgrade : Vinča Institute of Nuclear Sciences, 2021)
The resistance seam welding is a welding technique that is often used for the creation of the leak-tight welds. It is a technique where the weld is created as a set
of overlapping weld nuggets between the cylindrical ...
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 ...
Fatty Acids of Some Moss Species from Germany
(Asian Journal Of Chemistry, Sahibabad, 2011)
The fatty acid composition of three mosses collected in Germany was preliminary analyzed by gas chromatography (GC-FID) and gas I chromatography-mass spectrometry (GC-MS) for the first time. It was found that Hypnum ...
Infrared properties of sintered α-MnSe
(De Gruyter, 2006)
Far-infrared reflection spectra of sintered α-MnSe were measured at room temperature. The measured spectrum had one pronounced peak in accordance with literature data and group theory estimation and one smaller peak resulting ...
