Optimization of plasmonic Al/TiO₂ thin film characteristics via scanning pulsed fiber laser deposition
...Show More Authors

The deposition method of perovskite solar cell layers significantly impacts device functionality and the achievement of industrial goals. Aluminum (Al) nanoparticles with rutile titanium oxide (TiO2) nanoparticle thin films are fabricated on Fluorine Tin Oxide (FTO) glass substrates by nanosecond pulsed fiber laser deposition (PLD) to be used as a plasmonic electron transport layer (ETL) in perovskite solar cell (PSC). The effect of various pulsed fiber laser parameters on the structural, optical, and surface morphology on Al/TiO2 films is extensively examined utilizing a variety of measurement techniques; X-ray diffraction (XRD), Ultraviolet–visible (UV–Vis) spectroscopy, Field emission scanning electron microscopy (FE-SEM) and Atomic Force microscope (AFM). XRD demonstrates that Al/TiO2 thin films has a mixed phase (anatase/rutile). The minimum average crystallite size of Al/TiO2 thin films deposited at (2 W - 40 kHz) is (19.8 nm). The absorption spectrum of the deposited Al/TiO2 thin film at (10 W - 20 kHz) shows a red-shifted absorption peak at 316 nm, while 307 nm is detected at (2 W - 20 kHz). As the pulse repetition rate rise (40, 60 kHz), a new absorption peak in the UV spectral region at 341 nm was observed. FESEM images demonstrate the nanoparticles’ uniformity and polycrystalline nature. The shape of nanoparticles becomes more uniform and smaller size when the power increases. The minimum power required to get a uniform film is 0.8 W nm with suitable thickness of 398.8 obtained by fitting the thickness values curve of Al/TiO2 thin films. The elemental analysis examined by the EDX spectrum of Al/TiO2 thin films consists of oxygen, aluminum, and titanium. AFM images reveal a granular microstructure, and a flat texture, with the lowest surface roughness. The obtained results from the current study indicate that the structural, optical, and morphological properties can be controlled by varying the fiber laser parameters to deposit an efficient plasmonic Al/TiO2 thin films could be used as an electron transport layer which open new trends to improve the performance of perovskite solar cell.

Monitoring the Vegetation and Water Content of Al-Hammar Marsh Using Remote Sensing Techniques
...Show More Authors

The object of the presented study was to monitor the changes that had happened in the main features (water, vegetation, and soil) of Al-Hammar Marsh region. To fulfill this goal, different satellite images had been used in different times, MSS 1973, TM 1990, ETM+ 2000, 2002, and MODIS 2009, 2010. A new technique of the unsupervised classification called (Color Extracting Technique) was used to classify the satellite images. MATLAP programming used the technique and separated Al-Hammar Marsh from other water features (rivers, irrigated lands, etc.) when calculated the changes in the water content of the study region. ArcGIS 9.3 (arcMAP, arcToolbox) were used to achieve this work and calculate area of each class.

AI-Shidyaq is considering one of the scholars' of Arab modern Renaissance. He
enjoyed a dusting nished status among the men of letters of his age. He added many things in
language and literature that made him, during the Arab modern Renaissance, a pioneer

Evaluation of Drinking Water Quality in Al Wahda Treatment Plant in Baghdad City- Iraq
...Show More Authors

This study aims to evaluate drinking water quality at the Al Wahda plant (WTP) in Baghdad city. A conventional water treatment plant with an average flow rate of 72.82 MLD. Water samples were taken from the influent and effluent of the treatment plant and analyzed for some physicochemical and biological parameters during the period from June to November 2020. The results of the evaluation indicate that treated water has almost the same characteristics as raw water; in other terms, the plant units do not remove pollutants as efficiently as intended. Based on this, the station appears to be nothing more than a series of water passage units. However, apart from Total dissolved solids, the mean values of all parameters in the study were

The meaning of the triple verb more with one letter in Diwan al-Shafi'i
...Show More Authors

The Diwan of Imam Al-Shafi’i acquires great importance, as Al-Shafi’i is an authority in the language, and when I saw that no one had preceded me in exploring its depths, I took my tool and turned my face towards it intending to study the triple verb in it. I stop at these verbs and the student pauses for their morphological forms, looking at the significance of the triple verb more with one letter, two letters, and three letters, and I found that they are many, and such research cannot contain them all, so the choice came to choose the triple verb more with one letter, and the significance of the increase in it, as the increase in The building necessitates an increase in the meaning, and from here the study was limited to the triple
