Enhanced sorption of Cu2+ from sulfate solutions onto modified electric arc furnace slag
(Elsevier Science Bv, Amsterdam, 2019)
Pristine electric arc furnace slag (EAFS) as well as EAFS modified by alkali activation i.e. alkali activated slag (AAS) have found a novel application as adsorbents used in Cu2+ removal from sulfate solutions. The adsorption ...
Thermal analysis of polylactic acid under high CO2 pressure applied in supercritical impregnation and foaming process design
(Elsevier B.V., 2019)
Thermal properties of extrusion and injection grade polylactic acid (PLA) were analysed using high pressure differential scanning calorimetry (HP-DSC) under CO2 pressures of up to 50 MPa. The greatest depression of melting ...
Mg/Cu co-substituted hydroxyapatite – Biocompatibility, mechanical properties and antimicrobial activity
(Elsevier Ltd, 2019)
The aim of this study was to improve the mechanical properties and to optimize antimicrobial activity of hydroxyapatite (HAP) by simultaneous doping with Mg and Cu ions in order to obtain material that would be able to ...
Estimation of residual strength of a crack-containing welded pressure vessel exposed to a subzero operating temperature
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
This paper presents a method for estimating the residual-strength of welded pressure vessel made of HSLA steel which contains a surface axial crack. In order to analyze the behavior of the structure, a set of specimens ...
Use of up-flow percolation test to assess the environmental properties of raw and treated fly ash
(Gheorghe Asachi Technical University of Iasi, Romania, 2019)
Fly ash (FA) is a by-product created from the burning of coal in thermal power plants. FA mainly consists of mineral compounds that make them naturally caustic. Despite this, research has shown that FA may be utilized as ...
Industrial steel waste as an iron source to promote heterogeneous and homogeneous oxidation/reduction reactions
(Elsevier Sci Ltd, Oxford, 2019)
This work examines the mill scale (MS) of hot rolling, a waste product formed in industrial steel processing. MS was evaluated as an iron source in promoting the oxidation of Reactive Red 120 azo dye in location-sourced ...
Drug repositioning for a rare genetic disorder progressive osseous heteroplasia (poh)
(Društvo genetičara Srbije, Beograd, 2019)
Progressive osseous heteroplasia (POH) is an ultrarare genetic disease of progressive ectopic ossification caused by heterozygous inactivating mutations of GNAS, the gene encoding the alpha subunit of the G-stimulatory ...
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 ...
The initial characteristics of the polypyrrole based aqueous rechargeable batteries with supercapattery characteristics
(Elsevier Science Bv, Amsterdam, 2019)
The electrochemically synthesized polypyrrole (PPy) is investigated as a possible active material of the low-cost aqueous based secondary power sources in combination with zinc, lead oxide, and lead sulfate. The discharge ...
Use of spent brewer's yeast in L-(+) lactic acid fermentation
(Inst Brewing, London, 2019)
The application of by-products from the brewing industry in lactic acid (LA) production was investigated in order to replace expensive nitrogen sources (such as yeast extract) with cheaper and renewable nitrogenous materials ...
