At-home bleaching: Color alteration, hydrogen peroxide diffusion and cytotoxicity
(2015-01-01)
This study evaluated the color change, cytotoxicity and hydrogen peroxide (HP) diffusion caused by different home bleaching protocols: 10% carbamide peroxide (CP) for 3 or 1.5 h, 6% hydrogen peroxide for 1.5 h or 45 min. ...
Monte Carlo-quantum mechanics study of magnetic properties of hydrogen peroxide in liquid water
(American Chemical Society, 2014-08)
A theoretical study of magnetic properties of hydrogen peroxide in water has been carried out by means of Monte Carlo simulation and quantum mechanics calculations. The solvent effects were evaluated in supermolecular ...

Degradation of the Oxirane Ring of Epoxidized Vegetable Oils with Hydrogen Peroxide Using an Ion Exchange Resin
(Elsevier Science, 2005-12)
The influence of different process variables (stirring, temperature, hydrogen peroxide concentration, particle diameter and amount of catalyst added) on the oxirane ring-opening reaction caused by hydrogen peroxide (H2O2) ...

Enhanced Hydrogen Peroxide Sensing Based on Tetraruthenated Porphyrins/Nafion/Glassy Carbon-modified Electrodes via Incorporating of Carbon Nanotubes
(Wiley & Sons, 2015)
The incorporation of carbon nanotubes to a Nafion/tetraruthenated cobalt porphyrin/glassy carbon electrode (GC/Nf/CoTRP vs GC/Nf/CNTCoTRP) enhanced the amperometric determination of hydrogen peroxide. Both electrodes ...
Hydrogen peroxide monitoring in Fenton reaction by using a ruthenium oxide hexacyanoferrate/multiwalled carbon nanotubes modified electrode
(ELSEVIER SCIENCE SALAUSANNE, 2012)
A novel amperometric sensor based on the incorporation of ruthenium oxide hexacyanoferrate (RuOHCF) into multiwalled carbon nanotubes (MWCNTs) immobilized on a glassy carbon electrode is described. Cyclic voltammetry ...
Electrocatalytic activity of nanohybrids based on carbon nanomaterials and MFe2O4 (M=Co, Mn) towards the reduction of hydrogen peroxide
(Wiley-VCH Verlag, 2018)
We report the advantages of hybrid nanomaterials prepared with electrogenerated ferrites (MFe2O4; M: Co, Mn) and multi-walled carbon nanotubes (MWCNTs) or thermally reduced graphene oxide (TRGO) on the electro-reduction ...
A multicommuted flow-based system for hydrogen peroxide determination by chemiluminescence detection using a photodiode
(2007-01-01)
A simple, rapid, and automated assay for hydrogen peroxide in pharmaceutical samples was developed by combining the multicommutation system with a chemiluminescence (CL) detector. The detection was performed using a spiral ...
