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 ...
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 ...
The presence and serological types of streptococcus suis strains isolated from pigs originating from some farms in Serbia
(Parlar Scientific Publications (P S P), Freising, 2012)
Streptococcus suis is a normal inhabitant of the respiratory system of pigs. Clinically healthy pigs are a major reservoir of the pathogen, but, as well, the most important link in the epidemiology of infection in humans. ...
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 ...
Influence of picosecond laser pulses on the microstructure of austenitic materials
(Springer, New York, 2011)
We investigate samples of austenitic materials - stainless steel and iron-based superalloy - which are widely used at high temperatures and pressures. The samples were exposed to Nd(3+):YAG laser pulses with a wavelength ...
Electrospun Poly(vinylbutyral)/silica Composite Fibres for Impregnation of Aramid Fabrics
(Materiale Plastice, 2014)
The poly (vinyl butyral)/silica (PVB/SiO2) composite fibers were produced by the electrospinning process. The experiments were performed with the PVB solution in concentration of 10 wt.% where ethanol was used as the ...
Isopiestic Determination of the Osmotic and Activity Coefficients of the {yNa(2)HPO(4) + (1-y)K2HPO4}(aq) System at T=298.15 K
(Springer/Plenum Publishers, New York, 2016)
Isopiestic measurements have been made for aqueous mixtures of Na2HPO4 and K2HPO4 at T = (298.15 +/- 0.01) K, at Na2HPO4 ionic strength fractions y = (0.2023, 0.4060, 0.6027, 0.8007, and 1), using KCl(aq) as the reference ...
Differences in the mode of thermomechanical processing between white gold alloys to produce semi-finished products
(Bulgarian Acad Science, Sofia, 2015)
The results of the investigation of the reduction degree on the hardness of a gold sample with chemical composition Au58,5Ag15Cu9,5Ni9Zn5Pd3 for old white gold alloy and Au58,5Ag18Cu10,5Ga8Zn5 (wt %) for new white gold ...
Solidified structure and leaching properties of metallurgical wastewater treatment sludge after solidification/stabilization process
(Taylor & Francis Inc, Philadelphia, 2016)
The presented study investigates solidification/stabilization process of hazardous heavy metals/arsenic sludge, generated after the treatment of the wastewater from a primary copper smelter. Fly ash and fly ash with addition ...
