(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 ...
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 effect of annealing temperatures on magnetic and electric properties of electrodeposited Ni85,3Fe10,6W1,4Cu2,2 alloy
(Natl Inst Optoelectronics, Bucharest-Magurele, 2014)
Ni-85,Ni-8 Fe-10,Fe-6 W-1,W-4 Cu-2,Cu-2 alloy powder consisting of an amorphous matrix and nanocrystals of an FCC solid solution of Fe, W and Cu in nickel was produced by electrodeposition. Heating the pressed powder sample ...
Landfill closure best available technique development: case study of Serbia
(Journal of Environmental Protection and Ecology, 2020)
Waste disposal is the last but inevitable step in waste management and it significantly effects the environment. According to the Serbian Waste Management Strategy, disposal sites should be closed and new, sanitary regional ...
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 ...
Experimental Investigation of Microstructure and Phase Transitions in Ag-Cu-Zn Brazing Alloys
(Springer, 2018)
Microstructure and phase transitions of selected brazing alloys from the Ag-Cu-Zn ternary system were investigated. Four ternary alloys with silver content in the compositional range from 25 to 60 wt.% were studied using ...
A comparative study of chromatographic lipophilicity and bioactivity parameters of selected spirohydantoins
(Taylor & Francis Inc, Philadelphia, 2020)
In this study, lipophilicity of 21 cycloalkylspiro-5-hidantoins was assessed. The overall goal of lipophilicity evaluation is preliminary investigation which should result in a decrease of the traditionally high attrition ...
