The antioxidant activity of different Satureja montana L. subsp. kitaibelii extracts was tested by measuring their ability to scavenge reactive hydroxyl radical during the Fenton reaction, using ESR spectroscopy. Also, the influence of these extracts on lipid peroxyl radicals obtained during lipid peroxidation of: (I) sunflower oil (37 C, 3h) induced by 4,4'-azobis(4-cyanovaleric acid) (ACVA) a...

Introduction: Dyes are visible materials and are considered as one of the hazardous components that make up industrial waste. Therefore it is removed from bodies of water, using various methods. In this regard, the Fenton oxidation process is one of the most effective ways to remove colored contaminants in aquatic environments, which has many applications today. Materials and Methods: In this...

A simple cobalt(II)/N-hydroxyphthalimide catalyst system has been identified for selective conversion of benzylic methylene groups in pharmaceutically relevant (hetero)arenes to the corresponding (hetero)aryl ketones. The radical reaction pathway tolerates electronically diverse benzylic C–H bonds, contrasting recent oxygenation reactions that are initiated by deprotonation of a benzylic C–H bo...

A CuAAC reaction was established for modular synthesis of end-stapled homo- and hetero-triple helical peptides, generating "clicked" macro-assemblies with enhanced thermal stability.

The influence of low-molecular-weight organic acids (LMWOAs), such as malonic acid, ethylenediaminetetraacetic acid, and oxalic acid, on the Fenton degradation of organic pollutants was examined under visible irradiation (lambda > 450 nm). The Fenton degradation of malachite green in the dark was completely blocked in the presence of LMWOAs. It was found that either visible light irradiation or...

The use of AOPs (Advanced Oxidation Processes) for the treatment of industrial wastewaters has increased during the last years. The process efficiency depends on the treatment conditions (temperature, pH, reagent dosage etc.) and it is very difficult to predict it because the reaction mechanisms are strongly affected by the mutual relationship among these parameters and the wastewater compositi...
