Improved compressive strength of alkali activated slag upon heating
(Elsevier Science Bv, Amsterdam, 2014)
This paper presents a study on thermal stability of alkali activated slag (AAS) prepared from electric arc furnace slag (EAFS) using a mixture of alkaline sodium hydroxide and sodium silicate solutions. The samples were ...
Mechanical and magnetic properties of composite materials with polymer matrix
(Technical Faculty, Bor, 2010)
Many of modern technologies require materials with unusual combinations of properties that cannot be met by the conventional metal alloys, ceramics, and polymeric materials. Material property combinations and ranges have ...
Experimental study of insulating properties and behaviour of thermal barrier coating systems in thermo cyclic conditions
(Elsevier Sci Ltd, Oxford, 2015)
The aim of this study was to improve the resistance of turbo jet engine parts exposed to high temperatures and overheating and sudden changes in temperature. For this purpose, three thermal barrier coating (TBC) systems ...
Quality attributes of a fermented whey-based beverage enriched with milk and a probiotic strain
(Royal Society of Chemistry, 2014)
Beverages produced by fermentation of whey have significantly lower viscosity, milder flavour and less viability of probiotic microorganisms compared to those obtained by fermentation of milk. Therefore, it is necessary ...
Hemp-based adsorbents for sequestration of metals: a review
(Springer Heidelberg, Heidelberg, 2019)
With the increasing focus on renewable materials and sustainability issues, the development of non-conventional materials from natural resources and possessing complexing properties is currently an area of extensive research ...
Thermodynamic characterization of binary mixtures of poly(propylene glycol) 425 with toluene and o-, m- and p-xylenes
(Academic Press Ltd- Elsevier Science Ltd, London, 2019)
Density rho, viscosity eta and refractive index n(D) have been experimentally measured for four binary mixtures of poly(propylene glycol) of average molecular weight 425 + toluene/o-xylene/m-xylene/p-xylene over the ...
Kinetics of Chalcopyrite Leaching by Hydrogen Peroxide in Sulfuric Acid
(MDPI, Basel, 2019)
In ores, chalcopyrite is usually associated with other sulfide minerals, such as sphalerite, galena, and pyrite, in a dispersed form, with complex mineralogical structures. Concentrates obtained by flotation of such ores ...
Hydrometallurgical Process for Selective Metals Recovery from Waste-Printed Circuit Boards
(MDPI, Basel, 2018)
This paper presents an experimentally-proved hydrometallurgical process for selective metals recovery from the waste-printed circuit boards (WPCBs) using a combination of conventional and time-saving methods: leaching, ...
Hydrothermal synthesis of TiO2/carbon composites and their application for removal of organic pollutants
(Elsevier, Amsterdam, 2019)
TiO2/carbon composites were synthesized by hydrothermal carbonization, using titanium isopropoxide and glucose precursor solution to obtain composites with Ti/C molar ratios ranging from 0.05 to 0.30. Characterization of ...
