Frequency-response-controlled multiple-resonator-based harmonic analysis
(Hertford : The Institution of Engineering and Technology, 2018)
This Letter proposes a modified method for the dynamic harmonic analysis of signals with non-stationary harmonics, which is based on the previously proposed multiple-resonator observer structure. An optimisation technique ...
Evaluation of the possibility of using normalization with cobalt in detection of anthropogenic heavy metals in sediments
(Nova Science Publishers, Inc., 2015)
Geochemical normalization with conservative elements has been effectively used for assessing the enrichment of metal pollutants and distinguishing their natural and anthropogenic sources. Without correcting for textural ...
Assessment of trace element contamination in the river and alluvial sediments using a sequential extraction technique and statistical analysis
(Nova Science Publishers, Inc., 2013)
This study presents the results of determination Cu, Cr, Zn, Pb, Cd, V, Ni, As and Hg content and assessment of their anthropogenic origin, mobility and contamination level in the river sediment (Tisa River and tributaries) ...
Efficient stabilization of Saccharomyces cerevisiae external invertase by immobilisation on modified beidellite nanoclays
(Elsevier Sci Ltd, Oxford, 2015)
The external invertase isoform 1 (EINV1) was immobilised on eight differently modified beidellite nanoclays, Modifications were composed of organo-modification with different amounts of surfactant - hexadecyl trimethylammonium ...
Bioactive Compounds in Wild, In vitro Obtained, Ex vitro Adapted, and Acclimated Plants of Centaurea davidovii (Asteraceae)
(Natural Products Inc, Westerville, 2015)
In vitro cultures were initiated from a single seed of Centaurea davidovii. Whole plantlets were regenerated and cultivated for several months on agar-solidified nutrient media differing by their composition: basal MS ...
Methanol oxidation on Pd/Pt(poly) in alkaline solution
(Elsevier, 2015)
Bimetallic electrodes prepared by Pd nanoislands spontaneously deposited on polycrystalline platinum, Pt(poly), at submonolayer coverage were explored for methanol oxidation in alkaline media. Characterization of obtained ...
Tehno-ekonomska analiza i ocena opravdanosti razvoja procesa i postrojenja za alkalnu aktivaciju bentonita u Srbiji
(Univerzitet u Beogradu, Naučna ustanova, Institut za hemiju, tehnologiju i metalurgiju, 2013)
Oxygen reduction reaction on palladium-modified zeolite 13X
(Springer, New York, 2015)
Palladium was dispersed over zeolite NaX by procedure of impregnation/thermal degradation of palladium acetylacetonate salt. Samples characterization was performed by X-ray diffraction, SEM analysis, and chemical analysis. ...
Electronic properties of environmental pollutants and their mutagenic activity: Nitro derivatives of azaphenanthrenes
(Oxford : Pergamon-Elsevier Science Ltd, 2015)
The physico-chemical properties of nitroazaphenanthrene isomers: 4-nitro-9-azaphenanthrene (4-N-9-Aph), 5-nitro-9-azaphenanthrene (5-N-9-Aph), 6-nitro-4-azaphenanthrene (6-N-4-Aph), 8-nitro-1-azaphenanthrene (8-N-1-Aph), ...
An adsorption-based mercury sensor with continuous readout
(Springer, New York, 2013)
A novel readout procedure for a mercury sensor has been proposed. The sensor is based on the surface adsorption. Mercury vapor is adsorbed at the surface of a thin gold layer patterned into four meanders which are connected ...
