Latex Metabolome of Euphorbia Species: Geographical and Inter-Species Variation and its Proposed Role in Plant Defense against Herbivores and Pathogens
(Springer, 2021)
Based on the hypothesis that the variation of the metabolomes of latex is a response to selective pressure and should thus be affected differently from other organs, their variation could provide an insight into the defensive ...
Stereospecific ligands and their complexes. Part X: Synthesis, characterization and in vitro antitumoral activity of platinum(IV) complexes with O,O '-dialkyl-(S,S)-ethylenediamine-N,N '-di-2-(4-methyl)pentanoate ligands
(Elsevier Science Sa, Lausanne, 2012)
Synthesis of four new platinum(IV) complexes 1-4, with bidentate N,N'-ligand precursors O,O'-dialkyl esters (alkyl = ethyl, n-propyl, n-butyl and n-pentyl), of (S,S)-ethylenediamine-N,N'-di-2-(4-methyl)pentanoic acid ...
Decrease of free fatty acid content in vegetable oil using silica supported ferric sulfate catalyst
(Elsevier Sci Ltd, Oxford, 2012)
A difficulty of biodiesel synthesis based on alkaline catalysts obviously exists if free fatty acids (FFAs) content in vegetable oil is above 0.5 wt.%. In this study, the ferric sulfate supported on silica (Fe-2(SO4)(3)/SiO2) ...
Electrochemical Examination of Copper(II) Complexes with Octaazamacrocyclic Ligand and Heterocyclic Dithiocarbamate
(Wiley-Blackwell, Malden, 2012)
Mixed ligand dinuclear copper(II) complexes of the general formula [Cu2(Rdtc)tpmc)](ClO4)3 with octaazamacrocyclic ligand tpmc and four different heterocyclic dithiocarbamate ligands Rdtc-, as well as the complexes ...
Ballistic transport through graphene nanostructures of velocity and potential barriers
(Iop Publishing Ltd, Bristol, 2011)
We investigate the electronic properties of graphene nanostructures when the Fermi velocity and the electrostatic potential vary in space. First, we consider the transmission T and conductance G through single and double ...
Synthesis and solution properties of poly(diphenyl itaconate)
(Elsevier, 1976)
Solid diphenyl itaconate monomer was obtained by esterification in the presence of diphosphorus pentoxide and polymerized in bulk with AIBN as initiator. The non-film forming polymer powder was characterized by fractionation, ...
Can volcanic dust suspended from surface soil and deserts of Iceland be transferred to central Balkan similarly to African dust (Sahara)?
(Switzerland : Frontiers Media S.A., 2019)
In this work we use chemical fingerprints as characteristics ratios of specific crustal elements Ca/Al, Fe/Al, K/Al, Mg/Al, Mn/Al, Ca/Fe, and Mg/Fe to investigate the long-range transport of volcanic aerosols from Iceland. ...
Degradation of α-nitroso-β-naphthol by UVA-B activated peroxide, persulfate and monopersulfate oxidants in water
(Elsevier, 2019)
Flotation reagents, especially new chelating agents represented by α-nitroso-β-naphthol, are the main components of cobalt mining drainage. This study reports the degradation of α-nitroso-β-naphthol by simulated UVA-B ...
Fluctuations of the number of adsorbed molecules in biosensors due to stochastic adsorption-desorption processes coupled with mass transfer
(Elsevier, 2012)
We derived a simple theory of fluctuations of the equilibrium number of adsorbed molecules in biosensors, caused by the stochastic nature of adsorption-desorption (AD) processes coupled with mass transfer. The two-compartment ...
Antioxidant properties of raspberry seed extracts on micronucleus distribution in peripheral blood lymphocytes
(Oxford : Pergamon-Elsevier Science Ltd, 2009)
This study addresses in vitro effects of raspberry (Rubus idaeus) seed extracts (RSE) on the frequency of micronuclei. We evaluated the effects of three different extracts (50%, 80%, and 100% methanol) in doses of 1.4, ...
