چکیده

Abstract TiO 2 composite photocatalysts with doping amounts of Ce (0.5%Ce/TiO , 1%Ce/TiO 2%Ce/TiO 3%Ce/TiO and 5%Ce/TiO )were synthesized via a sol-gel method.The structure morphology the prepared composites were characterized by XRD, SEM, DRS, XPS. At same time, photocatalytic effect on rhodamine B (RhB) solution under simulated visible light irradiation was explored.The results indicated that crystal powder catalyst anatase type directional aggregation Ce/TiO photocatalyst showed ice cream flowers-shaped structure.The photocatalysis activity best when 3%.The degradation rate RhB 96% in 120 min, which 50% higher than pure .Hydroxyl radical (⋅OH) played leading role whole photodegradation reaction system, its contribution about 66.4%.

The effect of date versus sugar on sensory, physicochemical, and antioxidant properties of ice cream

Background: Despite the popularity of ice cream, its high content of sugar and fat is worrisome. Substituting sugar with natural and useful resources is one possible solution. Dates (Phoenix dactylifera) are rich in carbohydrates and are a good source of energy; they also have a large amount of phenolic compounds and anthocyanin. Aims: The aim of this ...

Textural and rheological properties of stevia ice cream

Ice cream contains high sugar content and therefore it is in contradiction with the concept of healthy diet. The objective of this study is to determine the suitability of using stevia as an alternative natural sweetener in making ice cream. Inhouse ice cream formulation (as the control) and three different concentrations of stevia ice cream formulations of (A, B and C) were used. Physical prop...

some properties of fuzzy hilbert spaces and norm of operators

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
