In this work, using the spin coating method to create polyvinylidene fluoride (PVDF)/polyethylene oxide (PEO) thin films, the effects of nano-tungsten oxide (WO₂) doping were investigated. The novelty of this research lies in its investigation of varying weight concentrations of WO₂ nanoparticles (NPs) within the composite films. Comprehensive characterization techniques were employed, including structural analysis via X-ray diffraction (XRD), which revealed a clear and prominent peak in the XRD of the PVDF/PEO films, and the films' polycrystalline nature with tetragonal structures. The grain size was noted to increase with higher WO₂ NPs doping. Field emission scanning electron microscopy (FE-SEM) showed

Nanocomposite membranes made of chitosan (Cs) concentrations, and polyvinyl alcohol (PVA) with a fixed ratio of (60:40), then incorporated with different concentrations of multi-walled carbon nanotubes (MWCNTs) (1, 1.5, 2, 2.5, and 3%) were created using the solution cast method. The membranes were identified using UV-vis spectroscopy, Fourier transform infrared (FTIR), and X-ray diffraction (XRD). The results demonstrated that the samples were sufficiently stable, and the interactions between nanoparticles and polymers were generally negligible. XRD patterns showed a crystalline phase of PVA, an amorphous phase of chitosan, and a more crystalline phase as MWCNTs were introduced. In particular, at high percentages of MWCNTs, the dominant

It may by said that there is a historical relationship between architecture and structure which was strongly affected by the technological developments. Therefore structure as a factor of the material base of architectural technology is very influencing factor in design activity, and in architectural configuration. Many, other points of views and transformations that appeared casted their shadows upon the Iraqi architecture of 20th century, each period carried the entry of architectural and structural styles which caused a variation in effect, So the knowledge gap that the research focuses on the absence of the role of structure (on the practical level as a direct influencing factor) in the shaping of Iraqi architecture. The subject matt

In this paper, a cold plasma system utilizing a high voltage of 13.5 kV of alternative (AC) and direct current (DC) was used under atmospheric pressure with argon (Ar)-gas at a flow rate of 2.5 l/min and a flowing time of 4 min to synthesize aluminum oxide (AlO) nanoparticles (NP). From the results, when DC was used, it was found that the absorption spectrum starts at 303 nm and gradually falls to 870 nm. With AC, the absorption spectrum was at 330 nm and then began to fall to 902 nm. The energy gap when utilizing DC and AC was 3.49 and 3.44 eV respectively. The analysis of the X-ray diffraction (XRD) patterns showed the structure of the NPs was amorphous, matching the pattern 42-1746. At DC, the average size of NPs formed, as deduced fr

In the present work, optical emission spectroscopy was used to diagnose the influence of A.C. power source frequency on the hollow magnetron sputtering discharge parameters (such as discharge emission, discharge current and voltage, glow discharge structure, temperature (T_e) and electron number density (n_e), Debye length (λ_D), and plasma parameter (N_D) of constant pressure. The electron temperature and number density were determined using the Boltzmann plots and the Stark broadening methods, respectively. The results illustrate that the normal glow discharge structure is similar to the D.C. discharge mode. The magnetic field has no impact on the fundamental discharge parameter in both A.C. fre

In this study, spin coating was used to prepare thin films of poly (2-methoxy-5-(2-ethylhexyloxy)-1, 4-phenylene vinylene) and silver (MEH-PPV/Ag) in this study. The physical characteristics of MEH-PPV/Ag thin films with various weight ratios (0.01, 0.02, 0.03, and 0.04%) were investigated by Fourier-transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FE-SEM), atomic force microscopy (AFM), X-ray diffraction analysis (XRD), and thermal testing. FTIR analysis showed that there were occurrences of the polymer's predicted chemical bonds. AFM tests show that when different amounts of silver are added to a polymer matrix, the film's surface roughness (root mean square) goes up from an average of 83.51 to 511.3

This research pertains to expand the formulation and applicability of using confinement and expansion due to Poisson’s ratio models for three dimensional non-linear finite element analysis of reinforced concrete members. A plasticity based model that acknowledges the asymmetric response of reinforced concrete under multiaxial stress conditions is used to account for the strength improvement under conditions of triaxial compression. Complex behavior of concrete such as compression softening and tension softening are incorporated to simulate concrete behavior. DIANA software is used for finite element analysis with the inclusion of confinement and
expansion effects. The concept of material pre-strains is extended to accommodate mod
