in this work a new resistance model has been presented based on that of henis-tripodi which can be used for interpretation of gas permeation data in composite and asymmetric membranes. in contrast to the previous works, in this model the fraction of the support layer surface that includes the pores filled with coating material has been taken into account. the influences of the filled pores on s...

Electrochemical coating processes are significantly affected by applied magnetic fields due to the generation of electromagnetic forces. The present research work has been undertaken to study the effect of coating parameters such as current density and alumina concentration on the characteristics of Ni-Al2O3 composite coating under static magnetic field. Ni-Al2O3 composite coating was applied o...

background: titanium (ti) implants are commonly coated with hydroxyapatite (ha). however, ha has some disadvantages such as brittleness, low tensile strength and fracture toughness. it is desirable to combine the excellent mechanical properties of zro2 and the chemical inertness of al2o3 with respect to the purpose of this project which was coating ti implants with ha-zro2-al2o3 to modify the s...

due to environmental risks generated by application of non-degradable and synthetic films, many researches have shown increasing tendency to edible coatings for storing food such as fruits and vegetables. whey protein is considered one of the most common sources of edible coatings and its use has been studied in the current research. in this paper, the simultaneous effect of coating with whey p...

The ferrocene/Poly(vinyl pyrrolidone) (PVP) composite membranes have been successfully prepared by using electrospinning and polarization coating techniques, respectively. The composite membranes were characterized by means of SEM (scanning electron microscopy), UV-vis absorption spectra, FT-IR (Fourier transform infrared), XRD (X-ray diffraction) and a radio frequency (RF) impedance/capacitanc...

In this study a novel edible film plasticized with glycerol was prepared from plums gum and carboxy methyl cellulose. The mechanical, gas permeability and thermal properties of blends films Incorporated with four levels of glycerol (5%, 10%, 15%, and 20% w/w) as plasticizer were determined. The aim of this study was to better understand the possibility of preparing composite edible film on the ...

Abstract: Electroless Nickel (EN) composite coatings embedded with Cr2O3 and/or MoS2 particles were deposited to combine the characters of both Cr2O3 and MoS2 into one coating in this study. The effects of the co-deposited particles on corrosion behavior of the coating in 3.5% NaCl media were investigated. The results showed that both Ni-P and Ni-P composite coatings had significant improvement...

To prolong the storage period of blueberry and improve its shelf-life quality, an edible coating based on chitosan was developed, different contents pectin were added to coating. In this study, Jerusalem artichoke residue used as a source pectin, which is byproduct processing inulin. The extracted has low cost high very suitable for preservation prepared chemical properties characterized by SEM...

The perishability of paneer, a popular and nutritious dairy product, poses serious threat to its marketability. This study is focused on applying an optimized edible coating based Sodium caseinate (SC) clove bud essential oil paneer. ingredients, SC, glycerol, pectin solution, were using the Central Composite Rotatable Design (CCRD) response surface methodology results showed that experimental ...
