Study of lipase-catalyzed synthesis of ascorbyl oleate using response surface methodology
(6th Central European Congress on Food, CEFood 2012, 2012)
L-ascorbic acid has good antioxidative properties but its efficiency in stabilizing fats and oils in products with high lipid content is negligible due to its hydrophilic characteristics. On the other hand, fatty acid ...
Pretreatment of used vegetable oil using CaO and CaO-ZnO for biodiesel production
(Czech Society of Chemical Engineering, 2014)
Structure and optical properties of noble metal and oxide nanoparticles dispersed in various polysaccharide biopolymers
(Spie-Int Soc Optical Engineering, Bellingham, 2011)
We present the results on the structure and the optical properties of noble metal (Ag, Au) and oxide (ZnO) nanoparticles synthesized by various methods in different polysaccharide matrices such as chitosan, glycogen, ...
Mechanochemically synthesized CaO·ZnO catalyst for biodiesel production
(20th International Congress of Chemical and Process Engineering, CHISA 2012 and 15th Conference on Process Integration, Modelling and Optimisation for Energy Saving and Pollution Reduction, PRES 2012, 2012)
The transesterification of triglycerides (vegetable oil) with methanol using CaO·ZnO mixed oxides catalyst were conducted to produce Fatty Acid Methyl Esters (FAME), i.e. biodiesel. The catalysts were used in the methanolysis ...
Effect of fermentation by Streptomyces sp. on antioxidant properties of spent coffee extracts
(6th Central European Congress on Food, CEFood 2012, 2012)
During espresso coffee preparation large amounts of spent coffee residues are produced and discarded daily as a part of the communal waste. However, there is a great potential in recycling this type of waste for extraction ...
Modelling of industrial trickle-bed reactor for hydrotreating of gas oil and light cycle oil blends
(19th International Congress of Chemical and Process Engineering, CHISA 2010 and 7th European Congress of Chemical Engineering, ECCE-7, 2010)
Hydrotreating of middle distillates is one of the key processes in modern refining technology. Results of hydrotreating of gas oil and LCO blends, obtained in an industrial hydrotreater, are presented. Increasing temperature ...
Application of non-equilibrium plasmas in top-down and bottom-up nanotechnologies and biomedicine
(Institute of Electrical and Electronics Engineers (IEEE), 2010)
In this paper we discuss how a better understanding of thermal and mainly non-thermal plasmas provides basis for their application in a number or nanotechnologies. One should bear in mind that one may design unique properties ...
Hydrogenated hydroxyapatite materials with improved biocompatibility
(24th European Conference on Biomaterials, EBS 2011, 2011)
Influence of Fe3+ on Photo catalytic Efficiency of Nanopowder-TiO2 and CeO2 - Comparative Study
(ICT Press, Prague, 2010)
Power Generation from Low Enthalpy Geothermal Fields by Design and Selection of Efficient Working Fluids for Organic Rankine Cycles
(Aidic Servizi Srl, Milano, 2010)
The presented work addresses the efficient power generation from low enthalpy geothermal fields through design and selection of working fluids for organic Rankine cycle (ORC) processes. A systematic methodology is employed ...
