Biofilms pose important economic and health risks in biomedical applications food industries. In this study, coatings that reduce the biofilm formation of Pseudomonas aeruginosa on polystyrene cell culture plates are deposited by plasma polymerization (3-aminopropyl)triethoxysilane using an atmospheric pressure jet system at three different power levels. Surface characterizations quantification...
Polymers with self-lubricating properties have been employed in various applications as bearing components and tribological surfaces, particularly where the use of liquid lubricant is infeasible, such space-related applications. This study reports on solutions for extreme temperature ranging from ?196 to 300 °C, which simulates operating conditions that materials space will encounter. Tribologi...
The effect of titanium nitride film on the properties of titanium bipolar plates used in polymeric fuel cell was investigated in this research. TiN coatings was deposited on the Ti-grade 1 substrate by using DC-sputtering method. Pure titanium was used as target and coating deposition was done in argon and nitrogen atmosphere. Different TiN thickness was developed by changing sputtering time. T...
Ricinoloxazoline maleinate (OXA) was grafted by melt free radical grafting onto polyolefins and elastomers to produce new compatibilizers for polymer blends. Effects of initial monomer and peroxide concentrations on the degree of grafting, on the amount of residual monomer, and on the side reactions were investigated. Reactive compatibilizers could be prepared with a suitable choice of processi...
thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
