Oxide Ceramics: The Role of Surface and Grain Boundaries for Reliable Functional Applications
Oxide ceramics find large application in several segments of the human life, as functional materials are used as components in several devices such as sensors of chemical species for improved environment, surge protectors ...
Composite membrane of niobium(V) oxide and cellulose acetate: Preparation and characterization
(Academic Press Inc Jnl-comp SubscriptionsSan Diego, 1997)
Reduced graphene oxides: influence of the reduction method on the electrocatalytic effect towards nucleic acid oxidation
For the first time a critical analysis of the influence that four different graphene oxide reduction methods have on the electrochemical properties of the resulting reduced graphene oxides (RGOs) is reported. Starting from ...
Influence of metallic oxides on ethanol oxidation
An improvement in ethanol oxidation electrocatalysis is possible with multifunctional Ptbased combinations. Thus, the addition to Pt of Sn, Ir or Ni enhances the ethanol oxidation reaction (EO) and shifts the onset oxidation ...
EVALUATION OF EUCALYPTUS KRAFT PULP LIGNIN THROUGH THE NITROBENZENE OXIDATION, COPPER OXIDE REDUCTION AND ACIDOLYSIS TECHNIQUES
(Centro Pesquisas Florestais, Ufsm, 2015)
High activity photocatalyst powder formed by three ceramic oxides
A Photocatalyst ceramic powder that presented high photoactivity based on TiO2 modified with 25% molar of SnO2 and up to 5% molar of Ag2O was obtained in the present work. The aforementioned ceramic powder was obtained ...
Effects of Alloyed and Oxide Phases on Methanol Oxidation of Pt-Ru/C Nanocatalysts of the Same Particle Size
(Amer Chemical Soc, 2009-05-14)
In this work, methanol oxidation was studied on carbon-supported Pt-Ru nanocatalysts, where the amounts of alloyed and oxide phases were modified by heat treatments in different atmospheres. Because particle growth was ...
ZnO-TiO2 composite formed by mixed oxides via polyol
(Trans Tech Publications Ltd, 2012-01-01)
Among the researches on preparation and test of nanostructured materials, titanium dioxide and zinc oxide have been the most frequent studied oxides. In order to extend their properties, composites have been prepared using ...
Differential inhibitory effect of alpha-, beta-, gamma-, and delta-tocopherols on the metal-induced oxidation of cholesterol in unilamellar phospholipid-cholesterol liposomes
(Institute of Food Technologists, 2002)
Cholesterol oxidation, products (COPs) are present in biological tissues and in foods. The inhibitory effect of antioxidants, such as tocopherols, on COPs formation has been only partially investigated. The antioxidant ...
