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 ...
Ag+, Cu2+ and Zn2+ doped hydroxyapatite/tricalcium phosphate bioceramics: Influence of doping and sintering technique on mechanical properties
(University of Novi Sad, Faculty of Technology, 2018)
Green hydroxyapatite ceramics were obtained by cold uniaxial and isostatic pressing of hydrothermally synthesized powders, pure hydroxyapatite and hydroxyapatite doped with Ag+, Cu2+ and Zn2+ ions. The ceramics were ...
Application of raw volcanic rock found in etna valley as an adsorbent of chromates, arsenates and selenates
(Savez inženjera metalurgije Srbije, Beograd, 2018)
This paper aims to determine the potential of volcanic rock found in Etna valley as an adsorbent of heavy metals in anionic form (chromates, arsenates, and selenates). Characterization of the volcanic rock was done with ...
Electrochemical behaviour of sildenafil citrate at gold and cystein modified gold electrode in acid solution
(Int Assoc Physical Chemists-Iapc, Zagreb, 2018)
Electrochemical behavior of sildenafil citrate (SC) at gold and cystein (Cys) modified gold electrode (AulCys) in 0.1 M H2SO4 was investigated by cyclic voltammetry (CV) and by square wave voltammetry (SWV). Effect of scan ...
Customizing nanotubular titania for photocatalytic activity
(Belgrade : Institute of Technical Sciences of SASA, 2018)
Semiconductor TiO2 photocatalysis is a heterogeneous catalysis, where the photons of the sun or artificial light source are activating the catalyst that enters in reactions. The targeted real-world applications are in ...
Microfiltration with periodic gas backwashing as an alternative technique for increasing permeate flux
(Savez hemijskih inženjera, Beograd, 2018)
In this paper, the influence of operating parameters (transmembrane pressure, temperature, the flow rate of retentate) on the cross - flow microfiltration of synthetic fruit juice and periodic backwashing with air was ...
Gamma-radiation effects on luminescence properties of Eu3+ activated LaPO4 phosphor
(Elsevier Science Bv, Amsterdam, 2018)
Eu3+ activated LaPO4 phosphors were prepared by a high-temperature solid-state method and irradiated to different high-doses gamma-radiation in the 0-4 MGy range. No effects of high-doses of high-energy radiation on ...
Synthesis, solvatochromism, and biological activity of novel azo dyes bearing 2-pyridone and benzimidazole moieties
(Scientific Technical Research Council Turkey-Tubitak, Ankara, 2018)
New azo dyes bearing 2-pyridone and benzimidazole moieties were prepared using diazotization of 4-(1H-benzo[d]imidazol-2-yl)aniline and coupling of the obtained diazonium salt with substituted 3-cyano-2-pyridones. Obtained ...
Adipoinductive effect of extracellular matrix involves cytoskeleton changes and SIRT1 activity in adipose tissue stem/stromal cells
(Taylor & Francis Ltd, Abingdon, 2018)
Adipose tissue (AT) homeostasis and expansion are dependent on complex crosstalk between resident adipose stromal/stem cells (ASCs) and AT extracellular matrix (ECM). Although adipose tissue ECM (atECM) is one of the key ...
Visible light absorption of TiO2 nanoparticles surface-modified with vitamin B-6: A comparative experimental and DFT study
(Srpsko hemijsko društvo, Beograd, 2018)
Surface modification of titanium dioxide nanoparticles (TiO2 NPs) with the biologically active molecule pyridoxine hydrochloride (vitamin B-6) was found to alter the optical properties. Microstructural characterization ...
