Thermodynamics of mixed and pure aqueous solutions of K2HPO4 at T=298.15 K
(Maik Nauka/Interperiodica/Springer, New York, 2015)
Experimental results on isopiestic measurements for three ternary aqueous solutions of K2HPO4 with KCl, KBr, and KNO3 at T = 298.15 K were modeled with the Clegg-Pitzer-Brimblecombe equation based on mole-fraction-composition ...
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 ...

(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 ...
Unusual growth of pollen tubes in the ovary of quince (cydonia oblonga mill.)
(Acta Scientiarum Polonorum, Hortorum Cultus, 2017)
This paper presents the results of a three-year research (2010-2012) of unusual growth of pollen tubes in the ovary in eight cultivars of quince in two pollination variants (self-pollination and open-pollination). Unusual ...
Potential Enrichment of Medicinal Mushrooms with Selenium to Obtain New Dietary Supplements
(Begell House Inc, Danbury, 2013)
The purpose of this study was to resolve the question of whether various selenium concentrations affect the ability of eight species, members of five genera, to produce mycelium biomass and absorb this trace element during ...
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 ...
Raman spectroscopy study of anodic film on Ag43Cu37Zn20 alloy
(Natl Inst Optoelectronics, Bucharest-Magurele, 2016)
The objective of this study was characterization of anodic film obtained when Ag43Cu37Zn20 alloy was treated electrochemically in 3.5% wt. NaCI under potentiostatic conditions. At the potential of +0.25 V a complex multilayer ...
Cobalt impregnated pillared montmorillonite in the peroxymonosulfate induced catalytic oxidation of tartrazine
(Springer, Dordrecht, 2018)
Aluminum pillared montmorillonite impregnated with cobalt (CoAP) was synthe-sized and characterized using chemical analysis, XRD and N-2-physisorption. CoAP was tested as a catalyst in the peroxymonosulfate (Oxone (R)) ...
