Effect of chemical treatments on the chemical composition and properties of flax fibers
(Srpsko hemijsko društvo, Beograd, 2017)
Flax fibers were modified with NaOH and NaClO2 under different conditions in order to not only clarify the effects of hemicelluloses and lignin removal on the morphology and properties of flax fibers, but also to improve ...
Synthesis, antioxidant and antimicrobial activity of carbohydrazones
(Srpsko hemijsko društvo, Beograd, 2017)
Fourteen mono- and bis-carbohydrazone ligands have been synthesized and characterized. Antioxidant activity of the substances was investigated together with possible (E)/(Z) isomerization, and explained on the most active ...
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 ...
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 ...
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 ...
Experimental investigation and modeling of thermophysical and extraction properties of choline chloride plus DL-malic acid based deep eutectic solvent
(Srpsko hemijsko društvo, Beograd, 2017)
The ability of non-toxic and biodegradable deep eutectic solvent (DES) choline chloride + DL-malic acid in mole ratio 1: 1, for the breaking of the azeotropes heptane + methanol and toluene + methanol by means of liquid-liquid ...
Removal of heavy metals from water using multistage functionalized multiwall carbon nanotubes
(Srpsko hemijsko društvo, Beograd, 2017)
The multistage synthesis of the multi-wall carbon nanotubes (MWCNT) modified with polyamidoamine dendrimers, A1/and A2/MWCNT, capable of cation removal, is presented in this work, as well as novel adsorbents based on these ...
A terephthalate-bridged two-dimensional heteronuclear Cu(II)-Mn(II) complex with a terminal 2,2 '-dipyridylamine ligand / Хетеронуклеарни дводимензионални Cu(II)–Mn(II) комплекс са мостовним терефталат-лигандима и терминалним 2,2'-дипиридиламин- лигандом
(Srpsko hemijsko društvo, 2017)
A terephthalate-bridged heteronuclear Cu(II)-Mn(II) complex [Cu2Mn(dipya)(2)(tpht)(3)](n), I, where dipya is 2,2'-dipyridylamine and tpht is the anion of 1,4-benzenedicarboxylic (terephthalic, H(2)tpht) acid was synthesized ...
Low-temperature-synthesized RuO2 from acidic chloride solution for the electrode coating applications
(Srpsko hemijsko društvo, Beograd, 2017)
For the preparation of RuO2 coatings on Ti substrate, the RuO2 was synthesized in acidic aqueous medium by simple one-step low temperature-controlled microwave (MW) irradiation. The physical composition of synthesized solid ...
Effective valorisation of barley bran for simultaneous cellulase and beta-amylase production by Paenibacillus chitinolyticus CKS1: Statistical optimization and enzymes application
(Srpsko hemijsko društvo, Beograd, 2017)
The agricultural raw industry generates large amounts of annually by-products that create disposal problems. Hitherto, there have been no reported papers about the simultaneous production of cellulase and beta-amylase from ...
