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 ...
Degradation of beech wood and wheat straw by Trametes gibbosa
(Springer, New York, 2017)
The aim of this study was to optimize cultivation conditions for Mn-oxidizing peroxidases and laccase production and selective degradation of beech wood and wheat straw lignin by Trametes gibbosa. To promote lignin ...
Application of cellulose acetate for controlled release of thymol
(Elsevier Sci Ltd, Oxford, 2016)
Cellulose acetate (CA) was investigated as a carrier towards development of material with controlled release of thymol as a natural substance with strong antibacterial properties using high pressure techniques. Effect of ...
Differences in the mode of thermomechanical processing between white gold alloys to produce semi-finished products
(Bulgarian Acad Science, Sofia, 2015)
The results of the investigation of the reduction degree on the hardness of a gold sample with chemical composition Au58,5Ag15Cu9,5Ni9Zn5Pd3 for old white gold alloy and Au58,5Ag18Cu10,5Ga8Zn5 (wt %) for new white gold ...
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 ...
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 ...
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 ...
Highly ordered macroporous gamma-alumina prepared by a modified sol-gel method with a PMMA microsphere template for enhanced Pb2+, Ni2+ and Cd2+ removal
(Elsevier Sci Ltd, Oxford, 2017)
The adsorption performance of three-dimensionally ordered macroporous (3DOM) gamma-alumina was investigated for enhanced Pb2+, Ni2+ and Cd2+ removal. The synthesis was based on a modified sol-gel method using a colloidal ...
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 ...
