Thermoanalytical study of cassava starch native and treated with hydrogen peroxide
Starch is one of the most important sources of reserve of carbohydrate in plants and the main source in the human diet due to its abundance in the nature. There no other food ingredient that can be compared with starch in ...
A multicommuted flow-based system for hydrogen peroxide determination by chemiluminescence detection using a photodiode
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 ...
Analysis of the color and fluorescence alterations of enamel and dentin treated with hydrogen peroxide
The aim of this study was to evaluate the effect of hydrogen peroxide whitening on fluorescence and color of bovine enamel and dentin. Twenty five dentin discs and 25 enamel discs, with 6 mm diameter and 1 mm thick, were ...
Assessing the effects of hydrogen peroxide bleaching agent on the shear bond strength of orthodontic brackets
Background: Tooth bleaching is, today, one of the most widespread cosmetic treatments in dental practice, so it is important to determine whether it can interfere with orthodontic bonding or not. Aim: The aim of this study ...
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 ...
Alumina-catalyzed Baeyer-Villiger oxidation of cyclohexanone with hydrogen peroxide
(Elsevier Science BvAmsterdamHolanda, 2008)
Dental bleaching with a 10% hydrogen peroxide product: a six-month clinical observation
Context: The possibility of bleaching vital teeth with peroxide-based products considerably revolutionized esthetic dentistry. Aim: The aim of this clinical study was to evaluate tooth color change and dental sensitivity ...
A systematic electronic structure study of the O–O bond dissociation energy of hydrogen peroxide and the electron affinity of the hydroxyl radical
(Springer New York LLC, 2018)
© 2018, Springer-Verlag GmbH Germany, part of Springer Nature. Hydroxyl radical reduction and peroxide bond breaking in hydrogen peroxide are reactions involved in various processes such as the Fenton reaction, which has ...
