Journal ArticleDOI
Porphyrins as Photoredox Catalysts: Experimental and Theoretical Studies
TL;DR: This work has found that free base tetraphenylporphyrin (H2TPP) is an efficient photoredox catalyst for the reaction of aldehydes with diazo compounds leading to α-alkylated derivatives.
Journal ArticleDOI
Nitroxide-coated silver nanoparticles: synthesis, surface physicochemistry and antibacterial activity
Magdalena Gozdziewska,Grzegorz Cichowicz,Katarzyna Markowska,Katarzyna Zawada,Elżbieta Megiel +4 more
TL;DR: In this paper, the facile synthesis and physicochemical characteristics of nitroxide-coated silver nanoparticles were described, which exhibit high antibacterial activity towards both Gram-negative and Gram-positive strains.
Journal ArticleDOI
¹H and ¹³C NMR-based sugar profiling with chemometric analysis and antioxidant activity of herbhoneys and honeys.
Marta K. Jamróz,Katarzyna Paradowska,Katarzyna Zawada,Katerina Makarova,Sławomir Kaźmierski,Sławomir Kaźmierski,Iwona Wawer +6 more
TL;DR: Herbhoneys have similar antioxidant properties to traditional honeys, being therefore of equal nutritional value and there was a noticeable influence of the extract concentration on the observed antioxidant effect.
Journal ArticleDOI
Surface enhanced Raman scattering (SERS) of 1-hydroxybenzotriazole adsorbed on a copper electrode surface
TL;DR: In this article, the adsorption of 1-hydroxybenzotriazole (BTAOH) on the copper electrode was studied by surfaceenhanced Raman scattering spectroscopy (SERS) as a function of electrode potential and pH value of the solution.
Journal ArticleDOI
Changes in antioxidant capacity of blood due to mutual action of electromagnetic field (1800 MHz) and opioid drug (tramadol) in animal model of persistent inflammatory state.
Paweł Bodera,Wanda Stankiewicz,Katarzyna Zawada,Bożena Antkowiak,Małgorzata Paluch,J. Kieliszek,Bolesław Kalicki,Andrzej Bartosiński,Iwona Wawer +8 more
TL;DR: The study revealed that single EMF exposure in 1800 MHz frequency significantly reduced antioxidant capacity both in healthy animals and those with paw inflammation, which was higher than that of rats which received only tramadol and were exposed to electromagnetic fields.
