A FAST, ROBUST ELECTROCHEMICAL METHOD FOR THE AUTOMATED DETERMINATION OF HYDROGEN PEROXIDE
(Sociedad Chilena de Química, 2009)
Ultracytochemical localization of hydrogen peroxide production by dental plaque bacteria
(1998)
This study looked for evidence of in vitro hydrogen peroxide (HP) synthesis in human dental plaque, using an ultracytochemical technique that included incubation in a CeCl3-rich medium. Supragingival dental plaque was ...
Studies on the Electrocatalytic Reduction of Hydrogen Peroxide on a Glassy Carbon Electrode Modified With a Ruthenium Oxide Hexacyanoferrate Film
(ELECTROCHEMICAL SCIENCE GROUP, 2011)
The electrocatalytic reduction of hydrogen peroxide on a glassy carbon (GC) electrode modified with a ruthenium oxide hexacyanoferrate (RuOHCF) was investigated using rotating disc electrode (RDE) voltammetry aiming to ...
Hydrogen peroxide and viral infections: A literature review with research hypothesis definition in relation to the current covid-19 pandemic
We reviewed the literature concerning the innate response from nasal and oral epithelial cells and their reaction
to hydrogen peroxide (H2O2). Hydrogen peroxide is produced physiologically by oral bacteria and plays a ...
Effect of pH on whitening efficacy of 35% hydrogen peroxide and enamel microhardness
(2018-03-01)
Objective: This study aimed to evaluate the effect of 35% hydrogen peroxide at different pH values and the degree of tooth staining on whitening efficacy and enamel microhardness. Materials and Methods: 90 enamel-dentin ...
Co2SnO4/Carbon nanotubes composites: A novel approach for electrochemical sensing of Hydrogen Peroxide
(Wiley-V C H Verlag GMBH, 2018)
For the first time Co2SnO4 (CTO)/Carbon nanotubes (CNT) composites were prepared and used to modify glassy carbon electrodes for the amperometric determination of hydrogen peroxide. The catalytic activity of composites ...
Horseradish peroxidase compound I as a tool to investigate reactive protein-cysteine residues: from quantification to kinetics
(ELSEVIER SCIENCE INC, 2011)
Proteins containing reactive cysteine residues (protein-Cys) are receiving increased attention as mediators of hydrogen peroxide signaling. These proteins are mainly identified by mining the thiol proteomes of oxidized ...
KINETIC STUDY OF THE OXIDATWE DECOLORIZATION OF XYLENOL ORANGE BY HYDROGEN PEROXIDE IN MICELLAR MEDIUM
(Sociedad Chilena de Química, 2010)
Photodecomposition of hydrogen peroxide in highly saline aqueous medium
(Brazilian Society of Chemical Engineering, 2006-09)
