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

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.

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.

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.
