A new dynamic friction model for modeling of elliptical vibration assisted turning (EVAT) was developed in this research. The periodic change of the friction force direction is known to be one of the most important causes of this phenomenon. In modeling of machining processes (including the EVAT process), static Coulomb friction model was employed by most of the researchers. Because of the peri...
in the present study, silver oxyfluoride modified silver electrode was employed to electrocatalytic oxidation of isoniazid. the process of oxidation and its kinetics were established by using cyclic voltammetry, chronoamperometry and amperometry techniques. the modified electrode shows a stable and linear response in the concentration range of 3×10−4 to 2.1×10−3 mol l-1 with a correlation coeff...
the ability of natural clinoptilolite and its modified forms were studied for removal of pahs from n-paraffin. surfactant modified zeolite (smz) was obtained by modifying clinoptilolite with hexadecyltrimethylammonium ion. homoionic forms of zeolite were obtained by ion exchange process using inorganic salts of desirable cations (e.g. ag+, fe3+…). natural clinoptilolite and its cation exchanged...
An easy method was used to modify the Cloisite Na+ with different cationic surfactants. To prevent the damages in the clay crystal structure, the process was taken without acid activation. The organo-modified montmorillonite (MMT) were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), thermal analysis (TG/DTG), field emission scanning electron microscopy ...
