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 ...
Diffusion of polyphenols from alginate, alginate/chitosan, and alginate/inulin particles
(Wiley, Hoboken, 2019)
Thymus serpyllum L (thyme) aqueous extract was encapsulated within three different types of particles. Thus, electrostatic extrusion was applied to obtain alginate, alginate/chitosan, and alginate/inulin particles with ...
Leaching properties of secondary lead slag stabilized/solidified with cement and selected additives
(Environment Protection Engineering, 2013)
Sodium lead slag, generated during secondary lead production, is characterized as hazardous waste. The aim of the study was to investigate leaching mechanism and behaviour of lead and arsenic from sodium lead slag previously ...
Solubility in the ternary system CaSO4 + Na2SO4 + H2O at 298.15 K
(Maik Nauka/Interperiodica/Springer, New York, 2011)
The solubility in the ternary system, aqueous mixture of CaSO4 and Na2SO4, at T = 298.15 K comprises five different salts: calcium sulfate dihydrate, mirabilite, thenardite, glauberite and labile salt. Using the Extended ...
Isopiestic Determination of the Osmotic and Activity Coefficients of K2HPO4(aq), Including Saturated and Supersaturated Solutions, at T=298.15 K
(Springer/Plenum Publishers, New York, 2011)
The osmotic coefficients of K2HPO4(aq) have been measured at T=298.15 K by the isopiestic vapor pressure method over the range of molalities from 1.3846 mola lt ...kg(-1) to 13.939 mola lt ...kg(-1) (oversaturation) with ...
Recent development of bioaugmentation methods for tobacco wastewater treatment
(University of Babes-Bolyai, Cluj-Napoca, 2015)
In production of cigarettes a lot of tobacco waste, with nicotine, goes into the environment. Hence, there is a need for an economic and efficient method to diminish the discharge of hazardous materials from tobacco ...
Combustion of Metallurgical Wastes Using Secondary Aluminum Foils
(Taylor & Francis Inc, Philadelphia, 2017)
Simulating the reactions in a complex system can lead to self-sustaining and energy efficient treatment of wastes in recycling promoting manner. In this contribution, the synergic combination of electric arc furnace dust ...
Tube for obtaining crystals in a laboratory furnaces
(Maik Nauka/Interperiodica/Springer, New York, 2011)
A model of an air-cooled tube with a number of movable plugs, installed in a laboratory tube furnace is presented. The setup (modular "crystallization shelf-comb") allows easy regulation and simultaneous crystallization ...
Detection of elements and radioactivity in pellets from long-eared owls (Asio otus) inhabiting the city of Belgrade (Serbia)
(Taylor & Francis Ltd, Abingdon, 2011)
In this study, we analysed pellets from long-eared owls (Asio otus) collected from four localities in Belgrade (Serbia). The pellets contained the remains of prey, namely voles (Arvicola terrestris) and field mice (Apodemus ...
An Improvement of Analytical I-V Model for Surrounding-Gate MOSFETs
(Amer Scientific Publishers, Stevenson Ranch, 2011)
The paper presents a realistic and necessary improvement of the existing current-voltage model for surrounding-gate MOSFETs. The basic model exploits the closed-form solution of Poisson's equation and drift-diffusion model ...
