the aim of this study is to compare the sensitometric properties of commonly used radiographic films processed with chemical solutions in different workload hospitals. the effect of different processing conditions on induced densities on radiologic films was investigated. two accessible double emulsions fuji and kodak films were exposed with 11-step wedge and processed with champion and cpac pr...

Scaffolds prepared from silk fibroin derived from cocoons of the domesticated silkworm moth Bombyx mori have demonstrated potential to support the attachment and growth of human limbal epithelial (HLE) cells in vitro. In this study, we attempted to further optimize protocols to promote the expansion of HLE cells on B. mori silk fibroin- (BMSF-) based scaffolds. BMSF films were initially coated ...

The aim of this work was to investigate effect of operational parameters on the photocatalytic degradation efficiency of a solution containing C. I. Basic Blue 41 BB41 in a recirculated rectangular photoreactor irradiated with a UV light. TiO_2 nano composite film was prepared via sol-gel dip coating method. The films were characterized by X-ray diffraction XRD, transmission electron microscopy...

In this study, in order to achieve effective coating of the homogeneous titanium dioxide (TiO2) thin film, UV irradiation pre-treatment was carried out to activate PC surfaces before coating. Sol-gel-based nanocrystalline TiO2 thin films were prepared by employing tetrabutyl-titanate as a precursor. Nanocrystalline TiO2 thin films were deposited by sol-gel spin coating on the treated substrates...

In this study, poly(3,3-dibenzyl-3,4-dihydro-2H-thieno[3,4-b][1,4]dioxepine)/platinum composite films (PProDOT-Bz2/Pt) were used as counter electrodes (CEs) in dye-sensitized solar cells (DSSCs). The composite films were prepared on fluorine-doped tin oxide (FTO) glass by radio frequency (RF) sputtering to deposit platinum (Pt) for 30 s. Afterwards, PProDOT-Bz2 was deposited on the Pt–FTO glass...

Both N-doped and undoped thin films of 3SnO2/TiO2 composite were prepared, by sol-gel and dip-coating methods, and then calcined at 600 °C for 2 hours. The films were characterized by FTIR, XRD, UV-Vis, SEM, and XPS, and their photocatalytic activities to degrade methylene blue in solution were determined, expecting these activities to correlate with the inactivation of bacteria, which was conf...

In this study, self-assembly regenerated silk fibroin (RSF) nanofibers were prepared and observed by Atomic Force Microscope (AFM). Then RSF films containing nanospheres and nanofibers were prepared and dissolved with poly (L-lactide-co-ε-caprolactone) (PLCL) with a blending ratio of 30/70 in hexafluoro-2-propanol (HFIP). In order to determine whether different nanostructures in the solution in...

Ruthenium-Carbon (Ru-C) nano-composite films were prepared by plasma-enhanced chemical vapor deposition (PECVD) and the effects of deposition conditions on the microstructure and electrical properies were investigated. The films consisted of agglomerated grains of 10 to 20 nm in diameter, in which Ru particles of 2.5 to 3.5 nm in diameter were dispersed in a C matrix. The C content of the films...

In this study, dependence of the 3rd order nonlinear coefficients on the size of the Au nanoparticles in the Au:SiO2 composite films together with on the wavelength have been examined experimentally. Composite films with various size of the metal nano-particles at constant Au volume fraction were fabricated by the use of alternating deposition technique using a multitarget RF magnetron sputteri...
