Calcium phosphate coating (CaP) has been employed for protein delivery, but the typical direct protein adsorption on the coating led to low incorporation content and fast release of the protein from the coating. By using bovine serum albumin (BSA) as a model protein, rapid biomimetic co-precipitation between calcium phosphate and BSA was employed to control the distribution of BSA within calciu...

Problems of adherence of thermal protective coatings to aerospace structures have become important with their use on vehicles such as the space shuttle and for jet engine turbine blades. In these structures a dielectric coating which acts as a thermal barrier. is bonded to a conductive substrate. Failure of these coatings to adhere to the substrate can result in catastrophic failure of the vehi...

The graphene nanosheets-based epoxy resin coating (0, 0.1, 0.4 and 0.7 wt %) was prepared by a situ-synthesis method. The effect of polyvinylpyrrolidone/reduced graphene oxide (PVP-rGO) on mechanical and thermal properties of epoxy resin coating was investigated using nanoindentation technique and thermogravimetric analysis, respectively. A significant enhancement (ca. 213% and 73 °C) in the Yo...

long-term use of indwelling medical catheters has often been hindered by catheter-associated nosocomial infections. in this study the effectiveness of silver coating of polystyrene and polyethylene polymers was investigated. polymer pieces of 2 cm2 each were coated with a thin layer of silver using electroless plating technique. silver-coated polymers were challenged with cultures of four diffe...

the aim of the current study was to design a porous osmotic pump–based drug delivery system for controlling the release of buspirone from the delivery system. the osmotic pump was successfully developed using symmetric membrane coating. the core of the tablets was prepared by direct compression technique and coated using dip-coating technique. drug release from the osmotic system was studied us...

In corrosion protection study, it is important to develop economically attractive test method for mitigation of corrosion damage of coated structure. Faster predication of protective behavior of any coating is a big challenge for the coating industries. In present work, in-house waterborne anticorrosive coating system was selected for study. The corrosion protection of coating evaluated as per ...

the genus fusarium is a species rich genus. different media are required to study themorphological characters and classify different species, a time consuming technique. in this study pecticzymograms were used to identify species and form species of fusarium isolates. fusarium isolates (318) wereobtained from different areas and hosts in isfahan province, iran. isolates were identified to speci...

Electrophoretic process was applied to the deposition of carbon nanotubes on the surface of carbon fabrics in order to enhance the properties of CNT/carbon fabric hybrid composites. Carbon fabrics were modified by two methods: Cu deposition by cathodic method and Cu coating by thermal vaporization method. CNTs were modified by PEI and oxidation treatment. The effects of carbon fabric and CNTs m...

Spectral domain optical coherence tomography (OCT) has recently attracted a lot of interest in the pharmaceutical industry as a fast and non-destructive modality for quantification of thin film coatings that cannot easily be resolved with other techniques. Because of the relative infancy of this technique, much of the research to date has focused on developing the in-line measurement technique ...
