Optimisation of the Recrystallisation Annealing Regime of Pd-5Ni Alloy Using experimental design and statistical analysis to understand the metallurgical properties of palladium alloy for ammonia oxidation catchment gauze applications
(Johnson Matthey Publ Ltd Co, Royston, 2016)
In this paper, changes in the mechanical properties of Pd-5Ni alloy are analysed after recrystallisation annealing in order to determine the optimal conditions for a thermomechanical processing regime for this alloy. The ...
Influence of some sol-gel synthesis parameters of mesoporous tio2 on photocatalytic degradation of pollutants
(Savez hemijskih inženjera, Beograd, 2016)
Titanium dioxide (TiO2) nanopowders were produced by sol-gel technique from tetrabutyl titanate as a precursor by varying some parameters of the sol-gel synthesis, such as temperature (500 and 550 degrees C) and the duration ...
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 ...
Single step recovery of lipase from Penicillium cyclopium by aqueous two-phase extraction
(Taylor & Francis Inc, Philadelphia, 2016)
Recovery of lipase from Penicillium cyclopium by aqueous two-phase extraction was studied with maximal possible crude enzyme loads. In polyethylene glycol/dextran and polyethylene glycol/salt systems the influences of ...
Calcium oxide based catalysts for biodiesel production: a review
(Savez hemijskih inženjera, Beograd, 2016)
Vegetable oils are mainly esters of fatty acids and glycerol, which can be converted to fatty acid methyl esters (FAME), also known as biodiesel, by the transesterification reaction with methanol. In order to attain ...
Characteristics of Wastewater Streams Within the Bor Copper Mine and Their Influence on Pollution of the Timok River, Serbia
(Springer Heidelberg, Heidelberg, 2016)
Wastewaters produced by mining and metallurgical treatment of polymetallic sulfide ores have polluted the Timok River in Serbia for more than 100 years. We have characterized seven different wastewater streams within the ...
Transport properties of binary liquid mixtures - Candidate solvents for optimized flue gas cleaning processes
(Srpsko hemijsko društvo, Beograd, 2016)
Thermal conductivities and viscosities of three pure chemicals, monoethanolamine (MEA), tetraethylene glycol dimethyl ether (TEGDME) and polyethylene glycol 200 (PEG 200) and two binary mixtures (MEA++TEGDME and MEA+ PEG ...
Biological treatment of colored wastewater by Streptomyces fulvissimus CKS 7
(Iwa Publishing, London, 2016)
This study aims to investigate the biological processes related to the biodegradable potential of growing microbial cells for contaminated water treatment. Thus, the use of the Streptomyces fulvissimus CKS 7 (CKS7) has ...
Influence of yarn folding on uv protection properties of hemp knitted fabrics
(Savez hemijskih inženjera, Beograd, 2016)
In the last years the media have highlighted the damage of the ozone layer and the resulting increase of ultraviolet radiation (UVR) reaching the Earth's surface. Prolonged and repeated, both occupational and recreational, ...
Immobilization of maltase from Saccharomyces cerevisiae on thiosulfonate supports
(Srpsko hemijsko društvo, Beograd, 2016)
In this study, two commercial supports (Eupergit (R) C and Purolite (R) A109) were chemically modified in order to introduce thiosulfonate groups, which could subsequently exclusively react with the cysteine residues on ...
