Biointerface dynamics - Multi scale modeling considerations
(Elsevier, Amsterdam, 2015)
Irreversible nature of matrix structural changes around the immobilized cell aggregates caused by cell expansion is considered within the Ca-alginate microbeads. It is related to various effects: (1) cell-bulk surface ...
Fixed bed property changes during scCO(2) extraction of natural materials - Experiments and modeling
(Elsevier Science Bv, Amsterdam, 2012)
Properties of the fixed bed of plant material during the extraction with scCO(2) from rapeseed were investigated for the two types of mechanical pretreatments: flaking and impact milling. Obtained results indicated that ...
Use of image analysis for durability testing of sulfur concrete and Portland cement concrete
(Elsevier Sci Ltd, Oxford, 2012)
Sulfur concrete was prepared by using the following initial components: sand as an aggregate, modified sulfur binder, and alumina as a filler. Portland cement concrete was made of the same aggregate, cement and water. The ...
Study of small chlorine-doped potassium clusters by thermal ionization mass spectrometry
(Wiley, Hoboken, 2012)
The theoretical calculations have predicted that nonmetal-doped potassium clusters can be used in the synthesis of a new class of charge-transfer salts which can be considered as potential building blocks for the assembly ...
Experimental measurement and modelling of viscosity of the binary systems pyridine or nicotine with polyethylene glycols at T = (288.15-333.15) K. New UNIFAC-VISCO and ASOG-VISCO interaction parameters
(Elsevier Science Bv, Amsterdam, 2013)
Viscosities of four binary mixtures: pyridine + PEG200, pyridine + PEG400, nicotine + PEG200 and nicotine + PEG400 have been measured in temperature range 288.15-333.15 K with temperature step of 5 K and at the atmospheric ...
The effect of grain size on the biocompatibility, cell-materials interface, and mechanical properties of microwave-sintered bioceramics
(Wiley, Hoboken, 2012)
The effect of decreasing the grain size on the biocompatibility, cellmaterial interface, and mechanical properties of microwave-sintered monophase hydroxyapatite bioceramics was investigated in this study. A nanosized ...
Effect of CO2 pre-treatment on scCO(2) extraction of natural material
(Elsevier Science Sa, Lausanne, 2012)
Pre-treatment of natural materials prior to their extraction strongly influences the efficiency of the process. Therefore, proper selection of pre-treatment method enables intensification of extraction process. Within this ...
Copper-Sulfate Pentahydrate as a Product of the Waste Sulfuric Acid Solution Treatment
(Springer, New York, 2012)
The aim of this study is synthesis of copper-sulfate pentahydrate from the waste sulfuric acid solution-mother liquor generated during the regeneration process of copper bleed solution. Copper is removed from the mother ...
Effect of chemisorbed carbon monoxide on Pt/C electrode on the mechanism of the hydrogen oxidation reaction
(Elsevier, 2009)
The influence of poisoning of Pt catalyst by CO on the kinetics and mechanism of H2 oxidation reaction (HOR) at Pt/C electrode in 0.5 mol dm-3 HClO4, saturated with H2 containing 100 ppm CO, was examined with rotating disc ...
Surfactant-modified clinoptilolite as a salicylate carrier, salicylate kinetic release and its antibacterial activity
(Elsevier Science Bv, Amsterdam, 2012)
The cationic surfactant benzalkonium chloride (BC) was used for modification of the natural clinoptilolite surface in order to prepare a suitable carrier for the salicylate anion. The salicylate-containing clinoptilolite ...
