Catalytic activity of SnO2- and SO4 /SnO2-containing clinoptilolite in the esterification of levulinic acid
(Elsevier B.V., 2019)
Catalysts based on natural zeolite - clinoptilolite loaded with either SnO2 (TOHCLI) or sulfated SnO2 (STOHCLI) were prepared and tested in the esterification of levulinic acid (LA) with octanol or ethanol. The Sn content ...
Kinetics of Chalcopyrite Leaching by Hydrogen Peroxide in Sulfuric Acid
(MDPI, Basel, 2019)
In ores, chalcopyrite is usually associated with other sulfide minerals, such as sphalerite, galena, and pyrite, in a dispersed form, with complex mineralogical structures. Concentrates obtained by flotation of such ores ...
Damage behavior of orthopedic titanium alloys with martensitic microstructure during sliding wear in physiological solution
(Sage Publications Ltd, London, 2019)
Wear damage behavior of new orthopedic Ti-13Nb-13Zr (mass %) alloy with martensitic microstructures developed by different thermo-mechanical treatments were examined during sliding in simulated physiological solution. The ...
Effect of gentisic acid on the structural-functional properties of liposomes incorporating beta-sitosterol
(Elsevier, Amsterdam, 2019)
Multifunctional liposomes incorporating beta-sitosterol were developed for delivery of gentisic acid (GA). The interactions of both compounds with phospholipid bilayer were interpreted viaeffects of different beta-sitosterol ...
Hydrothermal synthesis of TiO2/carbon composites and their application for removal of organic pollutants
(Elsevier, Amsterdam, 2019)
TiO2/carbon composites were synthesized by hydrothermal carbonization, using titanium isopropoxide and glucose precursor solution to obtain composites with Ti/C molar ratios ranging from 0.05 to 0.30. Characterization of ...
Multifunctional use of magnetite-coated tuff grains in water treatment: Removal of arsenates and phosphates
(Elsevier Science Bv, Amsterdam, 2019)
Natural filtration material tuff (T) was modified by coating with nano-sized magnetite. The grain fraction of 0.6-1.9 mm was submitted to hydrothermal synthesis of magnetite. Thus formed magnetite modified tuff (MMT) was ...
Soluplus (R), Eudragit (R), HPMC-AS foams and solid dispersions for enhancement of Carvedilol dissolution rate prepared by a supercritical CO2 process
(Elsevier Sci Ltd, Oxford, 2019)
The present work is aimed towards designing advanced materials by means of sustainable processes. In that sense, the utilization of supercritical CO2 (scCO(2)) for processing of pharmaceutical polymers (Soluplus (R), ...
Functional bioreactor characterization to assess potentials of nanocomposites based on different alginate types and silver nanoparticles for use as cartilage tissue implants
(Wiley, Hoboken, 2019)
In this work, functional characterization of biomaterials concerning potential application as articular cartilage implants was performed by using a biomimetic bioreactor with dynamic compression in the physiological regime ...
