Carbon nanotubes (CNTs) and quantum dots (QDs) are among the promising nanomaterials due to their unique properties. This study aims to synthesize and characterize multi-walled CNTs and QDs using the hydrothermal method. MWCNTs were synthesized at a temperature of 200°C using Ferrocene and Sulfur as precursors, while QDs were prepared at a temperature of 160°C using Polyethylene glycol (PEG). To fabricate the nanocomposite films, MWCNTs and QDs were mixed at different weight ratios (3:1, 2:2, and 1:3) through ultrasonic dispersion. The resulting mixture was then used to form films on glass surfaces. Characterization of the composites was carried out using a series of analyses including Fourier-transform infrared spectroscopy (FT-IR), field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), and electrical conductivity measurements. From the FESEM measurements, spherical particles of various sizes were observed, with a wide size distribution of less than 10nm. XRD analysis revealed d-spacing values of 0.34nm, 0.39nm, and 0.46nm for all the mentioned weight ratios. Additionally, the diameter of the particles ranged from 32.48nm to 31.96nm, with a length of approximately 1µm. The electrical conductivity of the films was also measured, and the obtained results indicated activation energies of 0.155eV, 0.14eV, and 0.25eV for the respective weight ratios. The resulting nanocomposite films exhibited unique properties as characterized by various techniques.

The effect of the solvent on ligand has been studied and the results have indicated that all the obtained complexes possess high stability. The percentage of metallic ions in the prepared complexes was obtained by the flame atomic absorption spectrometer. A careful analysis of the elements showed a great compatibility between the theoretically calculated and practically obtained ratios. The results of magnetic sensitivity showed that Cr(III),Ni(II) and Cu(II)-complexes possessed magnetic para qualities while the other complexes possessed magnetic dia qualities, as well as the molar conductivity of the prepared complexes was studied and the results showed that all complexes possess the ionic Based on the results obtained, the synthetic formulas of chelated complexes were proposed revealing that the investigated thiazolele azo ligand behaves as a triple ligand.","PeriodicalId":446021,"journal":{"name":"Muthanna Journal of Pure Science","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135155236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since the use of image processing has succeeded in solving many complicated problems in the medical field, it can now be employed to aid in the fight against COVID-19 and control it by extracting the relevant features collected from medical imaging datasets and categorizing using machine learning and deep learning approaches in order to diagnose and predict the COVID-19 disease. This study provides an overview of current findings on machine learning methods that have been applied to COVID-19 and aspects related to the types of algorithms, the medical dataset used, and the accuracy of researchers’ results. This paper, review the latest proposed models for COVID-19 classification and diagnosis applied to CT scans and chest X-ray images to provide further insight into disease reduction. COVID-19 diagnosis is critical for identifying an infected person and preventing the virus from spreading. Because diffusion is rapid, an automated rapid diagnostic mechanism is required to deal with a huge population so image processing methods are the most suitable technology for this. These models’ accuracy ranged from 80.6% to 100%, demonstrating that image- processing methods can be used to assess and diagnose COVID-19 clinically.","PeriodicalId":446021,"journal":{"name":"Muthanna Journal of Pure Science","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135155237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Polymer-ceramic composites have a high dielectric constant and are widely used for embedded capacitor applications. It is critical to use polymer poly methyl methacrylate (PMMA) as thin films capacitors for the gate dielectric in organic field-effect transistors (OFETs). In this work, thin films of polymer PMMA were prepared by using spin coating at different speeds (1500, 2000, 2500, 3000 and 3500 rpm) to control the film thickness and study the effect of the thickness on the dielectric properties. Thin film thickness was measured by using field emission scanning electron microscopy (FESEM) to take cross-section images. We found that the film thickness decreased with increased rotational speed from 27387 nm at 1500 rpm to 10600 nm at 3500 rpm. The values of the capacities were nearly stable with increasing frequencies when thickness equal to or larger than (14366 nm), but their increased with increased frequency at thickness (10600 nm), and the dielectric constant also decreases with increasing thin films thickness. The best result of capacitance value was at thickness 10600nm which equal to (5.753 nF) and dielectric constant equal to (3.511) which represents best value that can be used as dielectric gate for Organic Field Effect Transistor (OFET).","PeriodicalId":446021,"journal":{"name":"Muthanna Journal of Pure Science","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117107150","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
