Aluminum coating was prepared on AZ91D magnesium alloy substrate using the electrophoretic deposition (EPD) method in absolute ethanol solvent. In order to determine the optimal concentration of AlCl3.6H2O additive, the zeta potential and size of particles in the suspension were measured in the presence of different concentrations of AlCl3.6H2O. The results showed that an appropriate coating is...

A novel electrophoretic separation technique is presented, where continuous demonstrated using free flowing liquid foams. Continuous foam electrophoresis combines the principle of capillary and interactions between analytes electrical double layer, with ability Free Flow Electrophoresis to continuously separate recover automatically. used provide a network deformable micro nano channels high su...

this paper is concerned with asphaltene deposition in fluid flowing through pipelines. brownian diffusion and drag, gravitational, thermophoresis, buoyancy, and shear removal are considered as possible mechanisms in the asphaltene deposition process. the thermo-physical properties of the fluid were obtained from iranian oil fields. a model was used in the pipeline deposition modeling to predict...

chemical vapor deposition (cvd) is one of the most popular methods for producing carbon nanotubes (cnts). the growth rate of cnts based on cvd technique is investigated by using a numerical model based on finite volume method. inlet gas mixture, including xylene as carbon source and mixture of argon and hydrogen as carrier gas enters into a horizontal cvd reactor at atmospheric pressure. in thi...

in this article electrochemical determination of captopril at the surface of the platinum coated nanoporous gold film (ptnpgf) electrode is reported using the cyclic voltammetry and amperometry. for the preparation of ptnpgf, the surface of npgf electrode was covered with cu layer using underpotential electrochemical deposition (upd).afterward, the copper layer is replaced with platinum ions vi...

in this work we sought to determine whether vesicles (liposomes/niosomes) were able to enhance finasteride concentration in the dermis layer, including the pilosebaceous units (psu). such enhancement could be beneficial in the treatment of some androgen-related skin disorders. hamster flank skin was used to study  3hfinasteride permeation via vesicles and a hydroalcoholic solution (ha). the dru...

Main text A 46-year-old African-American male with a history of type-1 diabetes (DM) was referred to the Rheumatology clinic for a further evaluation of possible systemic scleroderma. He reported a 3-year history of skin thickening and hyperpigmentation on his back and shoulders. Over the last 12 months, his symptoms progressed, involving the proximal arms, legs, and back with sparing of his ha...
