Utilization of supercritical carbon dioxide for development of antibacterial surgical sutures
(Elsevier B.V., 2022)
Outbreak of surgical infections and bacterial resistance against synthetic antibiotic has prompted research towards development of antibacterial medical devices. For that purpose, absorbable surgical sutures were impregnated ...
Extraction of hyperforin and adhyperforin from St. John's Wort (Hypericum perforatum L.) by supercritical carbon dioxide
(Elsevier, Amsterdam, 2008)
St. John's Wort (Hypericum perforatum L.) was extracted with supercritical carbon dioxide (SC CO2) under 10, 15 and 20 MPa and at 313 and 323 K. The influence Of SC CO2 density (400-800 kg/m(3)) was examined with respect ...
Supercritical carbon dioxide extraction of essential oils from plants with secretory ducts: Mathematical modelling on the micro-scale
(Elsevier, Amsterdam, 2007)
In this study, the supercritical carbon dioxide extraction of essential oils from plants which contain secretory ducts as essential oil reservoirs was investigated and modelled. Supercritical carbon dioxide extraction of ...

(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 ...
Supercritical carbon dioxide extraction of sesquiterpenes from valerian root
(Elsevier Science Bv, Amsterdam, 2007)
Supercritical carbon dioxide extraction of sesquiterpenes from valerian root was investigated. Extractions from cultivar Arterner zuctung and two wild grown valerian subspecies were performed. The influence of extraction ...
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 ...
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 ...
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, ...
Modelling of non-catalytic biodiesel synthesis under sub and supercritical conditions: The influence of phase distribution
(Elsevier, Amsterdam, 2012)
Biodiesel, a mixture of fatty acid methyl esters, is widely used as renewable bio-based alternative fuel for internal combustion engines. Kinetic model of non-catalytic biodiesel synthesis at elevated temperature and ...
Modelling and optimization of supercritical CO2 extraction of St. John's Wort (Hypericum perforatum L.) using genetic algorithm
(Elsevier Science Bv, Amsterdam, 2012)
Modelling and optimization of the extraction of St. John's Wort using supercritical fluid is the subject of this study. Applying conservation of mass, two partial differential equations were written for solute concentration ...
