Polypyrol film was deposited on SS304by employing CPCvoltametery method, then coated with nano TiO2 (PPy/TiO2 )and used as a photocatalysis for degradation of somedyesacid fushin, methylenblue, methyl orange and methyl red. The SEM and XRD analysis indicated nano size of TiO2 deposits as 20nm on the polypyrol film. The UV result of absorption revealed that this film increased the rate of degrad...

یکی از روشهای متداول برای جلوگیری از تغییر شکل و خواص قطعات در تماس با گازهای داغ، از قبیل پره توربین و دیواره محفظه احتراق، استفاده از تکنیک سرمایش لایه ای (film cooling) می باشد. در روش سرمایش لایه ای شکافی (slot film cooling) سیال خنک کن مانع مانع از انتقال حرارت بین گازهای داغ و سطح فلز می شود. در این حالت می توان تحلیل جریان را به صورت دوبعدی انجام داد. اما در روش سرمایش لایه ای تک سوراخه ...

The interactive and multi-protagonist (IMP) film is a novel concept that extends the hypermovie genre. The IMP film is based on the common structures of linear narrative storytelling and provides the viewer with various decision points within the evolving story that support an active choice among different protagonists’ views. The viewer will thus be elevated to the role of a decision maker. Th...

In recent years, the demand for thin film coatings on large area substrates has been rapidly increasing. Coating is some times required to make an object harder, or to provide the surface with particular electrical and optical properties. Hence, research on thin film science has received much attention due to its tremendous applications in modern technology. The importance of coatings and the s...
