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 ...
Influence of hematite nanorods on the mechanical properties of epoxy resin
(Srpsko hemijsko društvo, Beograd, 2017)
The mechanical properties of nanocomposites obtained by incorporation of fairly uniform hematite nanorods (alpha-Fe2O3 NRs) into epoxy resin were studied as a function of the content of the inorganic phase. A thorough ...
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 ...
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 ...
Applicability of zeolites in potassium and nitrate retention in different soil types
(Srpsko hemijsko društvo, Beograd, 2017)
Environmental protection and sustainable agricultural production require the use of inexpensive and environmentally acceptable soil supplements. Objectives of this study were to investigate the influence of the addition ...
Statistical optimization of bioethanol production from waste bread hydrolysate
(Journal of the Serbian Chemical Society, 2021)
A recent trend in sustainable bioethanol production is the use of agricultural waste or food waste as an inexpensive and the most available feedstock. Bread waste is the major food waste that could be successfully used for ...
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, ...
Efficient pollutants removal by amino-modified nanocellulose impregnated with iron oxide
(Srpsko hemijsko društvo, Beograd, 2016)
A novel adsorbent, NC-PEG, obtained by modification of nanocellulose (NC) with PEG-6-arm amino polyethylene glycol (PEG-NH2) via maleic anhydride (MA) linker, was used for removal of Cd2+ and Ni2+ from water. A subsequent ...
Characteristics of the citrate-based zinc-polyaniline secondary cell with supercapattery behaviour
(Srpsko hemijsko društvo, Beograd, 2019)
The electrochemical characteristics of zinc-polyaniline (PANI) secondary cell in the electrolyte containing 0.8 M Na citrate, 0.3 M NH4Cl and 0.3 M ZnCl2 is investigated. Based on the measurements of potentials and voltage ...
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 ...
