Conventional and nanostructured YSZ coatings were deposited on the IN-738 Ni super alloy by the atmospheric plasma spray technique. The oxidation was measured at 1100°C in an atmospheric electrical furnace. According to the experimental results the nanostructured coatings showed a better oxidation resistance than the conventional ones. The improved oxidation resistance of the nanocoating could ...

manganese metal-organic framework (mn-mof) containing mn2+ ions, benzenetricarboxylic acid (btc) and n,n-dimethylformamid (dmf) was prepared and used as catalyst for oxidation of alkenes such as 1,1-diphenylethylene, trans-stilbene, cyclohexene, norbornene, styrene and cyclooctene to epoxides with 33-92% conversion and 75-100% selectivity and oxidation of alkanes such as fluorene, adamantane, e...

fat oxidation during exercise can be influenced by exercise intensity and duration, training status, diet and physical activity level. however, few studies have investigated the effect of time of day on the rate of fat oxidation during exercise. thus the present study was designed to investigate the effect of time of day on indexes of fat oxidation in active young women. for this purpose, 14 he...

the present study aimed to compare substrate oxidation and total energy expenditure during running with low and moderate intensity until exhaustion and one hour after exercise in obese male students. for this purpose, in a crossover study design, 11 male university students (mean age 20.45±1.69 years, bmi 31.26±1.3 kg/m2, body fat percentage 28.47±3.53 %) participated in this study. two exercis...

the present study is concerned with measuring and simulating soot formation and combustion in turbulent liquid fuel spray flames. soot concentrations inside the combustor are measured by filter paper technique. the simulation is based on the solution of the fully-coupled conservation equations for turbulent flow, chemical species kinetic modeling, fuel droplet evaporation and combustion and soo...

this article reports a study of the thermo-oxidation and biodegradation in the soil of low-density polyethylene/starch films (ldpe/starch) by infrared spectroscopy: films of ldpe/starch blends of different composition (starch content range from 0 to 15% w/w),were prepared and exposed to thermo-oxidation at different temperatures at 80, 90 and 100°c,and buried in the soil of public dump during 3...

in this study, the antioxidant activity and protective effects of purslane seed water-methanolic extract (pswme) in stabilizing soybean oil (sbo) were tested. dpph radical scavenging activity of pswme at different concentrations varied significantly (p< 0.05), ranging from 15.41% to 79.06%. total phenolic content in pswme was 121.09 mg gallic acid equivalent (gae) kg-1 dw. the protective effect...
