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 ...
An apparatus proposed for density measurements in compressed liquid regions at pressures of 0.1-60 MPa and temperatures of 288.15-413.15 K
(Srpsko hemijsko društvo, Beograd, 2015)
In this work, an apparatus for density measurements in the compressed liquid regions is presented. This installation is based on the use of a DMA HP density measuring cell and a DMA 5000 densimeter (both instruments are ...
PVB/sepiolite nanocomposites as reinforcement agents for paper
(Srpsko hemijsko društvo, Beograd, 2016)
In order to improve the mechanical properties of paper, 1, 3 and 5 wt. % of sepiolite were dispersed in a poly(vinyl butyral) (PVB) matrix and coated onto the surface of schrenz (110 g m(-2)). Deagglomerated sepiolite ...
Thermal investigation of some chelate Ni(II) complexes
(Serbian Chemical Society, Belgrade, 1999)
Several diamine-nickel(II) complexes have been prepared and the kinetic parameters of their decomposition reactions investigated. The complexes undergo a gradual thermal decomposition. First, water is lost, followed by the ...
Electrochemical deposition and characterization of AgPd alloy layers
(Srpsko hemijsko društvo, Beograd, 2018)
The AgPd alloys were electrodeposited onto Au and glassy carbon disc electrodes from the solution containing 0 001 mol dm(-3) PdCl2 + 0.04 mol dm(-3) AgCl + 0.1 mol dm(-3) HCl + 12 mol dm(-3) LiCl under the non-stationary ...
Biodegradation of cotton fabric impregnated with TiO2 nanoparticles
(Srpsko hemijsko društvo, Beograd, 2019)
Commercial P25 TiO2 nanoparticles are widely exploited as an efficient photocatalyst. In the textile domain, these nanoparticles are used for the production of self-cleaning, highly UV protective textiles, with an antimicrobial ...
Electrophoretically deposited hydroxyapatite-based composite coatings loaded with silver and gentamicin as antibacterial agents
(Srpsko hemijsko društvo, Beograd, 2019)
Increasing need for improved, compatible bone tissue implants led to the intensive research of novel biomaterials, especially hydroxyapatite (HAP)-based composite materials on titanium and titanium alloy surfaces. Owing ...
Synthesis of 5-(substituted phenylazo)-6-hydroxy-4-methyl-3-cyano-2-pyridones from ethyl 3-oxo-2-(substituted phenylazo)butanoates / Sinteza 5-(supstituisanih fenilazo)-6-hidroksi-4-metil-3-cijano-2-piridona iz etil-3-okso-2-(supstituisanih fenilazo)butanoata
(Serbian Chemical Society, Belgrade, 2011)
A new procedure for the synthesis of known azo pyridone dyes is presented. A series of 5-(substituted arylazo)-6-hydroxy-4-methyl-3-cyano-2-pyridones were prepared from ethyl 3-oxo-2-(substituted phenylazo)butanoates and ...
Prediction of excess molar volumes of binary mixtures by Prigogine-Flory-Patterson (PFP) and extended real association solution (ERAS) models
(Srpsko hemijsko društvo, Beograd, 2017)
In this paper, the Prigogine-Flory-Patterson (PFP) theoretical model and the extended real association solution (ERAS) model for the prediction of the excess molar volumes of 17 binary sets of alcohols (methanol, ethanol, ...
The structure directing role of 1,3-diaminopropane in the hydrothermal synthesis of iron(III) phosphate
(Srpsko hemijsko društvo, Beograd, 2004)
13-Diaminopropane (DAP) was used as a structure-directing agent for the hydrothermal synthesis of an organically templated iron phosphate. During crystallization at 180 degreesC, iron phosphate (FePO-DAP) with a layered ...
