Separation of Cu(II) ions from synthetic solutions and wastewater by raw and calcined seashell waste
(Desalination Publ, Hopkinton, 2018)
The limestone and lime are agents widely used for separation of toxic metals from contaminated water. To reduce the exploitation of natural limestone deposits, appropriate replacements are sought out among the waste materials ...
Biodiesel synthesis and kinetic analysis based on MnCO3/Na silicate as heterogeneous catalyst
(Srpsko hemijsko društvo, Beograd, 2018)
The MnCO3/Na silicate (Mn/Na/Si mole ratio of 4.65:1:1.65) catalyst in the form of solid particles with diameter of 0.99-1.99 mm was used as a catalyst for transesterification of soybean oil in batch autoclave at different ...
Cleaner production and environmental sustainability: Analysis of the Serbian petrochemical plant
(Taylor & Francis Inc, Philadelphia, 2018)
The approach proposed in this paper emphasizes the methodology of examining the possibility of increasing energy efficiency in the case of industry, such as a petrochemical complex, which is at the same time marked as the ...

The aim of the current work was to assess obtain a single crystal of calcium tungstate doped with neodymium - (CaWO4:Nd3+), and after that, the crystal was characterized with various spectroscopic methods. The single crystal ...
High temperature transesterification of soybean oil with methanol using manganese carbonate as catalyst
(Savez hemijskih inženjera, Beograd, 2018)
The manganese carbonate catalyst, prepared by precipitation method, was used in transesterification of soybean oil under subcritical condition of methanol. Catalyst samples were characterized by X-ray diffraction (XRD), ...
Modelling of pure components high pressures densities using CK-SAFT and PC-SAFT equations
(Srpsko hemijsko društvo, Beograd, 2018)
SAFT equations of state have been widely used for the determination of different thermo-physical and phase equilibria properties. In order to use these equations as predictive models it is necessary to calculate the model ...
Helicobacter Pylori Eradication Therapy is Not Associated with the Onset of Inflammatory Bowel Diseases. A Case-Control Study
(Medical Univ Press, Cluj-Napoca, 2018)
Background & Aims: A negative association between H. pylori and inflammatory bowel disease (IBD) has been previously reported. There were also case reports suggesting a new onset of IBD 6-12 months after H. pylori eradication ...
