Ultrasound as a physical treatment of stillage for lactic acid fermentation / Ultrazvuk kao fizički tretman za pripremu džibre za mlečno-kiselinsku fermentaciju
(Nacionalno društvo za procesnu tehniku i energetiku u poljoprivredi, Novi Sad, 2016)
In this study, the stillage from the bioethanol production on wasted bread has been used as a substrate for fermentation by lactic acid bacteria. Ultrasound has been studied as a physical treatment of wasted bread stillage ...
Cyanuric chloride functionalized silica nanoparticles for covalent immobilization of lipase
(Wiley-Blackwell, Hoboken, 2016)
BACKGROUNDIn this work, fumed nano-silica (FNS) was chemically modified to amino (AFNS) and subsequently to cyanuric chloride (CCAFNS) modified silica and tested for the immobilization of lipase from Candida rugosa (CRL). ...
Lactic acid production on a combined distillery stillage and sugar beet molasses substrate
(Wiley, Hoboken, 2016)
BACKGROUNDUtilization of wastes and industrial by-products for production of valuable bio-based chemicals has economic and environmental advantages. The aim of this study was to investigate utilization of two industrial ...
Photocatalytic Ability of Visible-Light-Responsive TiO2 Nanoparticles
(Amer Chemical Soc, Washington, 2016)
The synthetic procedures for preparation of free-standing and attached to polymer support surface modified TiO2 nanoparticles (NPs) with absorption extended into the visible spectral region due to charge transfer complex ...
Heavy Metals Fractionation in Agricultural Soils of Pb/Zn Mining Region and Their Transfer to Selected Vegetables
(Springer International Publishing Ag, Cham, 2016)
Improved understanding of the relationships between heavy metals fractionation in agricultural soils and biological uptake could be obtained by analysing samples of biota in parallel with sequential extraction of their ...
Failures of brass condenser tubes
(Society for Structural Integrity and Life, Institute for Material Testing, 2016)
Causes of failure of brass condenser tubes (CuZn28Sn1) in a thermal power plant in Serbia are analysed. Results of testing by Fourier transformed infrared spectroscopy (FTIR) have indicated the presence of ammonia and ...
Biodiesel production by methanolysis of waste lard from piglet roasting over quicklime
(Elsevier Sci Ltd, Oxford, 2016)
Waste lard from piglet roasting and quicklime (basically CaO) as a priceless fatty feedstock and a cheap solid catalyst, respectively were tested for the biodiesel production by methanolysis in a batch stirred reactor at ...
Physico-chemical and mechanical properties and antibacterial activity of silver/poly(vinyl alcohol)/graphene nanocomposites obtained by electrochemical method
(Elsevier Sci Ltd, Oxford, 2016)
Silver/poly(vinyl alcohol) and silver/poly(vinyl alcohol)/graphene nanocomposites in different forms (colloid dispersion, thin films and hydrogel discs) were synthesized by electrochemical reduction of Ag+ ions at constant ...
Chemometrics in biomonitoring: Distribution and correlation of trace elements in tree leaves
(Elsevier, Amsterdam, 2016)
The concentrations of 15 elements were measured in the leaf samples of Aesculus hippocastanum, Tilia spp., Betula pendula and Acer platanoides collected in May and September of 2014 from four different locations in Belgrade, ...
Waste Lard Methanolysis Catalyzed by KOH at Moderate Temperatures
(Wiley-VCH Verlag Gmbh, Weinheim, 2016)
The KOH-catalyzed methanolysis of waste lard from piglet roasting in a moderate temperature range was investigated in order to establish the reaction kinetics. For comparison, lard and thermally treated lard were also ...
