Sepiolite functionalized with N-[3-(trimethoxysilyl)propyl]ethylenediamine triacetic acid trisodium salt. Part I: Preparation and characterization
(Srpsko hemijsko društvo, Beograd, 2015)
Natural sepiolite from Andrici (Serbia) was functionalized by covalent grafting of N-[3-(trimethoxysilyl)propyl]ethylenediamine triacetic acid trisodium salt onto the Si-OH sepiolite groups. The functionalized material, ...
The importance of using hydrogen evolution inhibitor during the Zn and Zn-Mn electrodeposition from ethaline
(Srpsko hemijsko društvo, Beograd, 2019)
Cyclic voltammetry was used for the characterization of zinc electro-deposition on steel from ethaline deep eutectic solution (1:2 choline chloride:ethylene glycol). The influence of 4-hydroxy-benzaldehyde (HBA) as an ...
Investigation of Bi2O3-rich part of Bi2O3-PbO phase diagram
(Srpsko hemijsko društvo, Beograd, 2017)
A new Bi-rich part of Bi2O3-PbO phase diagram was determined using differential thermal analysis and X-ray powder diffraction techniques. Four solid solutions, alpha-Bi2O3, gamma-Bi2O3, d-Bi2O3 and ss(ss)-Bi8Pb5O17, can ...
Maltose-mediated, long-term stabilization of freeze- and spray-dried forms of bovine and porcine hemoglobin
(Srpsko hemijsko društvo, Beograd, 2019)
Slaughterhouse blood represents a valuable source of hemoglobin, which can be used in the production of heme-iron based supplements for the prevention/treatment of iron-deficiency anemia. In order to obtain a stable ...
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 ...
The production of cellulase from the waste tobacco residues remaining after polyphenols and nicotine extraction and bacterial pre-treatment
(Srpsko hemijsko društvo, Beograd, 2019)
Agricultural by-products are generated in large amounts in various industries, creating a serious disposal problem. Valorisation of tobacco waste for the extraction of value-added compounds and the production of enzymes ...
Modification of natural clinoptilolite and ZSM-5 with different oxides and a study of the obtained products in lignin pyrolysis
(Srpsko hemijsko društvo, Beograd, 2015)
In this work, different metal oxides (MO) supported on two types of zeolites: 1) natural clinoptilolite (NZ) and 2) synthetic zeolite, ZSM-5 were prepared and tested as catalysts in the fast pyrolysis of hardwood lignin. ...
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 ...
Influence of the content of hard segments on the properties of novel urethane-siloxane copolymers based on a poly(epsilon-caprolactone)-b-poly(dimethylsiloxane)-b-poly(epsilon-caprolactone) triblock copolymer
(Journal of the Serbian Chemical Society, 2011)
A series of novel thermoplastic urethane-siloxane copolymers (TPUSs) based on a alpha,omega-dihydroxy-[poly(epsilon-caprolactone)-b-poly(dimethylsiloxane)-b-poly(epsilon-caprolactone)] (alpha,omega-dihydroxy-PCL-PDMS-PCL) ...
A study of the barrier properties of polyethylene coated with a nanocellulose/magnetite composite film
(Srpsko hemijsko društvo, Beograd, 2016)
The morphological, thermal and barrier properties of low-density polyethylene/polycaprolactone-modified nanocellulose hybrid materials were investigated in this study. Nanocellulose/magnetite (NC-Fe3O4) nanocomposite and ...
