Supercritical extraction of phloroglucinols from St. John's wort (Hypericum Perforatum L.) - Process optimization, mathematical modeling and antimicrobial activity
(Phytochemicals: Occurrence in Nature, Health Effects and Antioxidant Properties, 2013)
St. John's Wort (Hypericum perforatum L.) has been widely used as an anti-inflammatory and healing agent in traditional medicine. Some para-pharmaceutical products, prepared from the extract of St. John's Wort, are frequently ...
Behavior of sulfur-polymer matrix composites with different fillers under acid and salt influence
(Polymer-Matrix Composites: Types, Applications and Performance, 2014)
Based on the nature of the matrix material, modern composites can be generally classified into three categories: polymer matrix composites, metal matrix composites, and ceramic matrix composites. Polymer matrix composites ...

Advances in mathematical modeling of supercritical extraction processes
(Mathematical Research Summaries, 2017)
A new trend in mathematical modeling of supercritical extraction process from plant material is presented. The most of the previously published models considered properties of the fixed bed of plant material during the ...
History, Synthesis and Properties of Azo Pyridone Dyes
(Textiles: History, Properties and Performance and Applications, 2014)
Azo dyes are synthetic organic colorants bearing chromophoric azo group. Over 50% of the colorants used belong to the azo compounds. Such a wide range of usage of azo dyes is due to the number of variations in chemical ...
Study of homogenization treatments of cast 5xxx series ai-mg-mn alloy modified with zn
(Light Metals 2012, 2016)
Microstructural changes of DC-cast 5xxx series AI-Mg-Mn alloy modified with Zn addition occurring during the homogenization treatments were studied through the thickness of a rolling ingot. The homogenization treatments ...
Removal of Synthetic Dyes from Wastewaters Using Horseradish Peroxidase
(New York: Nova Science Publishers, Inc., 2019)
Horseradish peroxidase is a heme-containing plant enzyme (HRP; EC 1.11.1.7) with a wide range of biotechnological and medical applications. In combination with hydrogen peroxide (H2O2) as an oxidant HRP can be used in the ...
Vegetable oil as a feedstock for biodiesel synthesis
(Vegetable Oil: Properties, Uses and Benefits, 2016)
Limited reserves of fossil fuels as well as the growing concern for the environment, has led to a worldwide search for renewable energy sources, among which biodiesel, a mixture of fatty acid methyl esters (FAME), is one ...
Effect of the Thermo-Mechanical Treatment on IGC Susceptibility of AA 5083 Alloy
(Light Metals 2014, 2014)
This work reports on the effect of thermo-mechanical treatment on IGC susceptibility of the AA 5083 alloy. Specimens underwent varied amount of cold work and final annealing was conducted at 240°C. Extent of the cold work ...
Micro and nanoscale morphology characterization of compatibilized polymer blends by microscopy
(Compatibilization of Polymer Blends: Micro and Nano Scale Phase Morphologies, Interphase Characteriz, 2019)
Polymer blends are mostly immiscible at a molecular level due to their large molecular mass. Therefore, the study of the way how two polymers are mixed together is of great interest. The properties of the polymer blend are ...
