The nanofibrous based on the polymer that was associated with PCL, doped with different ratios of titanium dioxide (TiO2) nanopowder were successfully synthesized using the electrospun method at RT and voltage (16 kV). The products were studied using SEM, AFM, FT-IR, XRD, DSC, TG and the D.C electrical characteristics. The result of SEM analysis sh...

Background The Iraqi environment, especially in the southern region, has been contaminated as a result of human activities. The detection of heavy metals in water samples is the preferred method for monitoring the toxic levels, which are very important for environmental protection and human health. Methods Heavy metal concentrations of lead (Pb),...

The solvothermal technique is utilized to deposit the nanoparticles into nano-thin films. Where Vanadium dioxide (20%) was mixed with (4%) of SiC, then added to CdO with (75%) to fabricated nanocomposites. PLD technique used Nd: YAG laser with a different energy to deposit nano-thin films on p-Si substrate to get [CdO75%/VO20%/SiC4%:p-Si]\documentc...

This paper's goal is to prepare PVA with ratios of 0.2, 0.4 and 0.6 wt% by casting method and with a thickness of 270 ± 5 micrometers. The morphological characteristics were examined (FE-SEM and FTIR) and the results showed that the composites have a homogeneous and granular structure and that ZnO is well distributed within the polymer, The reason...

This paper aims to fabricate a nanocomposite made of polyvinyl alcohol, titanium dioxide, and natural pomegranate dye that can function as a sunlight sensor for solar cells. The thin films' structural, optical and electrical properties of (Pomegranate/PVA-TiO2) were studied. Images from (FE-SEM) taken at a concentration of 0.3 weight percent reveal...

The aim of this paper, nanocomposite (PVA/TiO2/Berry dye) films is prepared with a solid state thin layer and the optical and some structural properties were measured. The prepared films showed an increase in absorbance due to the increase in the concentration of Berry dye. Also, due to the dyeing of these films the transmittance (79%) decreased. E...

It was investigated how titanium dioxide nanoparticles affected the optical properties of polyvinyl alcohol. Polymer nanocomposites (PVA-TiO2) are created via stirring and casting. The results demonstrate that transmittance improves from 75% to 95% while titanium dioxide concentration enhances the absorbance of nanocomposites. Nanocomposite films m...

The nanocomposite (PVA/TiO 2 /crocus) was prepared and four films were obtained with different concentrations of crocus dye. The results of optical microscopy observed nanoparticles created a continuous network inside polymers. This network had routes that allowed charge carriers to move via them inside the nanocomposites. The vibrational peaks at...

Nanoparticles are one of the most important technologies of today and the future. This groundbreaking technology is considered a very significant domain among all the fields of science due to its tangible capacity in improving products, treating diseases, serving mankind in all spheres of life, and realizing future scientific revolutions in the fie...

In this study lower surface hardness was measured and found increases with increasing exposure time, also lower surface hardness depend on intensity and graphene and silica with methacrylate the basic component of the filling into a uniform distribution of stress, It is able to reduce .the incidence .of stress concentration, result in a major growt...

Abstract The interactions existing between 2 distinctive small molecules of the gas (CO, NO2 and NH3) and graphene (double and single vacancy graphene) were examined with utilizing the Density Functional Theory (DFT) computations for the purpose of exploring their possible gas sensor applications. Also, electronic and structural characteristics o...

Lead oxide (PbO) thin films were deposited on unheated glass substrates, using the vacuum thermal deposition with a rate of deposition 0.7 nm/ s, at 130nm thickness .The annealing temperature was varied from 523 to 723K for 2 hr . X-ray diffraction (XRD) analysis was used to study the structural and crystallite size of PbO thin film. Before anneali...
