In situ Al-27 NMR kinetic investigation of zeolite A crystallization
(Elsevier Science Bv, Amsterdam, 2014)
In this study, in situ Al-27 NMR spectroscopy was used to gain detailed information concerning kinetics of zeolite A crystallization. Changes of relative intensity and width at half-height of NMR lines at 59 ppm ascribed ...
A structure-property relationship study of bent-core mesogens with pyridine as the central unit
(Royal Soc Chemistry, Cambridge, 2014)
Three series of bent-core mesogens having pyridine as the central unit have been synthesized and characterized. A series of 2,6-diaminopyridine derivatives capable of forming inter- and intramolecular hydrogen bonds exhibit ...
Electrochemical Degradation of the Pesticide Dimethenamid-P at Gold, DSA Platinum and Ruthenium Oxide Electrodes in Different Electrolytes
(Wiley-VCH Verlag Gmbh, Weinheim, 2014)
For the first time the electrochemical degradation of the pesticide dimethenamid-P was studied. Its direct electrochemical degradation, using potential cycling at a gold electrode, was performed by cyclic voltammetry and ...
Efficiency Assessment of Natural Biopolymers as Encapsulants of Green Tea (Camellia sinensis L.) Bioactive Compounds by Spray Drying
(Springer, New York, 2015)
In this study a bottom-up approach of designing functional ingredients from green tea extract is proposed by a systematic investigation of 12 different natural biopolymers and their efficiency as carrier materials of green ...
Edible blend films of pectin and poly(ethylene glycol): Preparation and physico-chemical evaluation
(Elsevier Sci Ltd, Oxford, 2018)
The aim of this study was the development of novel polysaccharide based films intended to be used as edible food packaging material. The films were prepared by solution casting method using highly methoxylated pectin (PEC) ...
Sensitivity analysis of the variational model for the particulate expansion of fluidized beds
(Taylor & Francis Inc, Philadelphia, 2020)
Fluidization experiments were performed by using spherical and non-spherical particles to examine the sensitivity of the variational model to three input parameters: U-mf, epsilon(mf) and U-t. Several correlations for U-mf, ...
Migration of cypermethrin to and through the PET containers and artificial neural network-based estimation of its emission
(Springer Verlag, 2019)
Nowadays, the extensive use of pesticides in crops production puts a significant challenge to minimize its side effects along with safe production, storage, and after-use treatment. This paper reports results related to ...
Modelling of dissolved oxygen content using artificial neural networks: Danube River, North Serbia, case study
(Springer Heidelberg, Heidelberg, 2013)
The aims of this study are to create an artificial neural network (ANN) model using non-specific water quality parameters and to examine the accuracy of three different ANN architectures: General Regression Neural Network ...
Antimicrobial Bioactive Band-Aids with Prolonged and Controlled Action
(Medical and Healthcare Textiles, 2010)
The paper discusses the antimicrobial bioactive band-aids, a modem means of wound management and healing, which are effective against a wide spectrum of microorganisms. Ion-exchange fibres and nonwoven textile materials ...
Solvent, structural, quantum chemical study and antioxidative activity of symmetrical 1-methyl-2,6-bis[2-(substituted phenyl)ethenyl]pyridinium iodides
(Springer, New York, 2018)
15 symmetric 1-methyl-2,6-bis[2-(substituted phenyl)ethenyl]pyridinium iodides were synthesized in this work. Their structures were characterized using IR, H-1 and C-13 NMR, and UV-Vis spectroscopy. DFT calculations indicated ...
