The friction theory for estimating viscosity of candidate solvents for flue gas desulfurization processes
(Elsevier Science Bv, Amsterdam, 2018)
In this study, applicability of the friction theory for the viscosity estimation of pure substances and binary liquid mixtures, used in regenerative flue gas desulphurization processes, was investigated. Theory was tested ...
Antimicrobial activity of metal oxide nanoparticles supported onto natural clinoptilolite
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
The antimicrobial activity of Cu2O, ZnO and NiO nanoparticles supported onto natural clinoptilolite was investigated in the secondary effluent under dark conditions. After 24 h of contact the Cu2O and ZnO nanoparticles ...
Preparation and Characterisation of Novel Biodegradable Material Based on Chitosan and Poly(Itaconic Acid) as Adsorbent for Removal of Reactive Orange 16 Dye from Wastewater
(Springer Int Publishing Ag, Cham, 2015)
Environmental protection has been a topic of great interest in recent years. Discharging azo dyes in aquatic systems contaminates water and causes serious ecological problems. Azo dyes are bio-accumulative, and, due to ...
A kinetic study of the release of vanillin encapsulated in Carnauba wax microcapsules
(Elsevier Sci Ltd, Oxford, 2012)
Thermal release of vanillin encapsulated in Carnauba wax microcapsules was studied by isothermal thermogravimetric analysis at 443, 453, 473, and 483 K. The thermal analysis data were analyzed kinetically and it was found ...
Effects of additives on nickel (ii)-chloride hydrogen reduction for production of nanocomposite catalysts
(Editura Stiintifica Fmr, Bucharest, 2012)
Catalysts based on nickel, as active component, exhibit suitable properties in various heterogeneous catalysis processes; however, they quickly deactivate due to deposits formation during exploitation and sintering at ...
Kinetics of sunflower and used vegetable oil methanolysis catalyzed by CaO·ZnO
(Elsevier Sci Ltd, Oxford, 2013)
The kinetics of heterogeneous methanolysis of sunflower oil and used vegetable oil were studied at different temperatures, ranging from 60 to 96 degrees C using CaO center dot ZnO as catalyst (2 wt% on the basis of oil) ...
Influence of hemicelluloses and lignin content on structure and sorption properties of flax fibers (Linum usitatissimum L.)
(Springer, Dordrecht, 2018)
In this work, alkali and oxidative treatments were employed to obtain flax fibers with different content of hemicelluloses and lignin, in order to study the influence of chemical composition on structure and sorption ...
The effects of chemical composition and firing temperature in heavy clay brick production - Chemometric approach
(Expert Fachmedien GmbH, 2014)
Factors influencing final clay brick properties are numerous, since the raw materials are highly heterogeneous. The chemometric approach is rarely used in analysis in this field, although it could significantly improve ...
Cloud Point Phenomena in the (Aniline or N,N-Dimethylaniline plus Water) Solutions, and Cosolvent Effects of Liquid Poly(ethylene glycol) Addition: Experimental Measurements and Modeling
(Amer Chemical Soc, Washington, 2015)
In this work, liquid phase behavior (cloud point phenomena) was studied for two binary and four aqueous pseudobinary systems containing aniline or N,N-dimethylaniline and poly(ethylene glycol) 200 Or poly(ethylene glycol) ...
Evaluating a primary healthcare centre's preparedness for disasters using the hospital safety index: Lessons learned from the 2014 floods in Obrenovac, Serbia
(Elsevier Ltd, 2019)
Various organizations have endeavored to develop assessment methods for the identification and management of weaknesses in hospital disaster preparedness. Although the largest number of patients receive their regular care ...
