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...

objective: radiochromic ebt3 film is a later generation of radiochromic films. the aim of this study is to compare ebt and ebt3 radiochromic films in radiotherapy fields of breast cancer. methods: a rando phantom was irradiated by a 6 mv siemens primus linac with medial and lateral fields of radiotherapy of breast cancer. dosimetry was performed in various points in the fields using ebt and ebt...

the use of mammography film-screen is limited in general radiography. the purpose of this study was to compare the effectiveness of mammographic film-screen and standard film-screen systems in the detection of small bone fractures. radiographs were taken from patients' extremities and neck areas using mammography film-screen and standard film-screen (n=57 each). fourteen other radiographs were ...

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...

in this research, the mechanical properties of seven types of nanofilm with differing amounts of silver and silver-clay particles were studied. the elasticity of modulus, tensile strength, toughness, elongation at break, tear strength and color of nanofilms were compared with those of ordinary ldpe film. results showed that the inclusion of nano particles increased the modulus of elasticity, te...
