Point Zero Charge Determination and Fluoride Adsorption on Natural Red Ash (Metal Oxide)

Assessing the Asphaltene Adsorption on Metal Oxide Nanoparticles

The Taguchi design of experiments (DOE) approach is adopted here to evaluate the impact ofeffective factors such as nanoparticles type, nanoparticles to model solution mass ratio, asphaltenestructure, and temperature on asphaltene adsorption equilibrium. Herein, the toluene-asphaltenesolution model is applied. Three commercially nanoparticles (SiO2, Al2O3, and TiO2) are used.<...

determination of some physical and mechanical properties red bean

چکیده: در این تحقیق، برخی خواص فیزیکی و مکانیکی لوبیا قرمز به-صورت تابعی از محتوی رطوبت بررسی شد. نتایج نشان داد که رطوبت بر خواص فیزیکی لوبیا قرمز شامل طول، عرض، ضخامت، قطر متوسط هندسی، قطر متوسط حسابی، سطح تصویر شده، حجم، چگالی توده، تخلخل، وزن هزار دانه و زاویه ی استقرار استاتیکی در سطح احتمال 1 درصد اثر معنی داری دارد. به طوری که با افزایش رطوبت از 54/7 به 12 درصد بر پایه خشک طول، عرض، ضخام...

Adsorption of Fluoride on Ccp

Oxide and Hydroxide Activity Determination in Oxide Doped Lithium Fluoride II. Total Oxygen Content Determination

where d = thickness of the film, ,o = resistivity of the film, = resistivity of the bulk material having the same structure and approximately the same number of defects as the films, l0 = mean free path of the charge carriers. The values of l0 calculated by the two methods were found to agree satisfactorily. Figs. 7 and 8 show the variation of the Hall mobility (/̂ H) with film thickness and sub...

Adsorption of molecular thin films on metal and metal oxide surfaces

Metal and metal oxides are widely used in industry, and to optimize their performance their surfaces are commonly functionalized by the formation of thin films. Self-assembled monolayers (SAMs) are deposited on metals or metal oxides either from solution or by gas deposition. The gas deposition enables the preparation of SAMs under very well controlled conditions in ultrahigh vacuum (UHV). Thio...
