Influence of different pre-treatment methods on isolation of extracts with strong antibacterial activity from lichen Usnea barbata using carbon dioxide as a solvent
(Elsevier, Amsterdam, 2013)
Multiplication and spreading of multiresistant pathogenic bacteria that cause fatal infections in humans and animals have boosted research on implementation of newer technologies for producing natural substances with strong ...
Synthesis of nano-crystalline NiFe2O4 powders in subcritical and supercritical ethanol
(Elsevier Science Bv, Amsterdam, 2016)
Nano-crystalline nickel ferrite has a broad range of applications due to its favourable magnetic properties. Those characteristics can be significantly influenced by the synthesis pathway including methods conducted in the ...
The problems in design and detailed analyses of energy consumption for biodiesel synthesis at supercritical conditions
(Elsevier, Amsterdam, 2009)
The main goal of this study is analysis the existing and recently published data related to design of larger scale plant for biodiesel synthesis at supercritical conditions. Such analysis was focused on the problem of ...
The phase equilibrium of triglycerides and ethanol at high pressure and temperature: The influence on kinetics of ethanolysis
(Elsevier Science Bv, Amsterdam, 2012)
Biodiesel synthesis by ethanolysis of triglycerides conducted under high pressure and at elevated temperature can lead to high levels of conversion and biodiesel yield over short reaction time. The vapour-liquid or ...
Advantages of supercritical fluid extraction for recovery of squalene from wine lees
(Elsevier Science Bv, Amsterdam, 2016)
Utilization of wastes from winery industry seems to be a cost-effective and an environmental friendly investment. A number of valuable components can be recovered from winery wastes and specifically from wine lees like ...
Development of advanced floating poly(lactic acid)-based materials for colored wastewater treatment
(Journal of Supercritical Fluids, 2021)
The release of industrial wastewater into the ecosystem prompted our research on the development of an efficient and biodegradable material that can be used for wastewater treatment. We optimized preparation of porous ...
Utilization of supercritical CO2 in bioactive principles isolation from Helichrysum italicum and their adsorption on selected fabrics
(Journal of Supercritical Fluids, 2021)
Helichrysum italicum (Roth) G. Don fil., Asteraceae, possesses numerous secondary plant metabolites with a wide range of biological activities. Yet, data on the potential of supercritical fluid extraction (SFE) in their ...
The analysis of simultaneous clove/oregano and clove/thyme supercritical extraction
(Elsevier, Amsterdam, 2011)
The goal of present work was to investigate and explain kinetics and mass transfer phenomena occurring during the SFE from the mixture of two plants with different initial composition. The extractions from pure clove, ...
SFE as a superior technique for isolation of extracts with strong antibacterial activities from lichen Usnea barbata L.
(Elsevier Science Bv, Amsterdam, 2012)
The number of cases of fatal infections in humans and animals caused by multiresistant and panresistant bacterial strains has been dramatically increased over the past 10 years on almost every continent. Therefore, ...
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 ...
