Surface properties of natural calcite filler treated with stearic acid
(University of Chemistry and Technology, Prague, 2009)
In order to obtain hydrophobic material, the water suspension of natural limestone with the high content of calcite (>95%), was treated with different amounts (0.5-4%) of stearic acid dissolved in chloroform. Thermal ...
Thermodynamics and characterization of shape memory Cu-Al-Zn alloys
(Elsevier Science Bv, Amsterdam, 2015)
The thermodynamic properties and the microstructure, hardness and electrical conductivity of shape memory alloys (SMAs) belonging to ternary Cu-Al-Zn system were studied by Muggianu model and experiment, respectively. The ...
Electrokinetic properties of hydroxyapatite under flotation conditions
(Academic Press Inc Elsevier Science, San Diego, 2010)
The effect of calcite supernatant, calcium, and carbonate ions on the hydroxyapatite (HA) zeta potential without and in the presence of sodium oleate (1 x 10(-4) mol L-1) was examined within the pH range from 4 to 12. The ...
Technologically Sustainable Route for Metals Valorization from Jarosite-PbAg Sludge
(MDPI, Basel, 2021)
By-products from zinc hydrometallurgy are classified as hazardous waste with strong leaching toxicities. Even though numerous research papers are dedicated to valorizing valuable metals in it, the primary management route ...
Influence of Mechanical Activation of a Cordierite-Based Filler on Sedimentation Stability of Lost Foam Refractory Coatings
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2019)
For the development of the Lost Foam refractory coatings with controlled rheologic properties, the influence of the mechanical activation process on the cordierite-based filler's properties change was examined. First of ...
Relation Between Edaphic Factors and Vegetation Development on Copper Mine Wastes: A Case Study From Bor (Serbia, SE Europe)
(Springer, New York, 2014)
The relationship between edaphic characteristics and vegetation growing on mine wastes in the Bor region (East Serbia, SE Europe) was studied using multivariate statistical analysis. The influence of edaphic factors on the ...
Waste Slag from Heating Plants as a Partial Replacement for Cement in Mortar and Concrete Production. Part I-Physical-Chemical and Physical-Mechanical Characterization of Slag
(MDPI, Basel, 2020)
Numerous factors influence the complexity of environmental and waste management problems, and the most significant goal is the reuse of materials that have completed their "life cycle" and the reduction in the use of new ...
Zeolite-group minerals in phonolite-hosted deposits of the Kaiserstuhl Volcanic Complex, Germany
(Mineralogical Soc Amer, Chantilly, 2019)
Subvolcanic phonolite intrusions of the Kaiserstuhl Volcanic Complex (Germany) show variable degrees of alteration. Their secondary mineralogy has been characterized by petrographic textural observations, bulk-rock powder ...
Adsorption of zearalenone by organomodified natural zeolitic tuff
(Academic Press Inc Elsevier Science, San Diego, 2007)
Adsorption of zearalenone (ZEN) by natural zeolitic tuff, modified with different numbers of octadecyidimethylbenzylammonium (ODMBA) ions, was investigated. The results of solid-state H-1 NMR analysis of the starting ...
Soil erodibility in European mountain beech forests
(Canadian Science Publishing, Ottawa, 2021)
Forests in Europe are currently not endangered by soil erosion. However, this can change with climate change or with intensified forest management practices. Using a newly established network of plots in beech forests ...
