The complicated structure and behavior of projectile and target nuclei with various projectile energy allows us to de ﬁ ne the reaction process and may aid in the investigation of the potential of creating superheavy elements (SHE) in the laboratory. Methods : The semiclassical and full quantum mechanical complete fusion cross section calculations s fus and the distribution of the fusion barrier D fus for the systems 12 C þ 50 Ti, 15 N þ 56 Fe, 16 O þ 63 Cu and 40 Ar þ 27 Al. The calculations have been carried out by using SCF code for semiclassical and CC code for quantum mechanical calculations. To account for the target and projectile relative motion, we modi ﬁ ed these codes. The fusion barrier distribution to be calculated directly from this code by subroutines written in Fortran language and added to the main code. The coupled-channel is considered by taking two channels only due to the dif ﬁ culty of solving coupled differential equations. Results : The obtained results for s fus and the D fus for the studied systems were compared to the related measured data and discussed. Conclusion : The semiclassical method used to describe the fusion reaction agrees very well with the quantum method and with the measured data and we can conclude that this semiclassical method can be used as alternative to quantum method to study the fusion reaction.","PeriodicalId":218143,"journal":{"name":"Al-Bahir Journal for Engineering and Pure Sciences","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126334434","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}

A series of metal ions Sn(II), Sn(IV), Co(II), Ni(II), and Cu(II) were used to prepare metal complexes through reaction of two moles of LS2 ligand with one mole of appropriate metal chloride. The prepared compounds were characterized by CHNS elemental analysis, infrared spectroscopy (FT-IR), 1H NMR-spectroscopy, mass spectroscopy, UV-visible spectroscopy, magnetic susceptibility, and conductivity measurements. Stoichiometry was determined using analytical and spectroscopic information and it was found to be 1:2 (metal to a ligand) for all complexes. The spectral data confirm the coordination of the LS2 ligand with all metal ions through sulfur atoms of dithiocarbamate moiety. Molar conductivity of complexes was measured using DMF as a solvent and it was indicated that all prepared complexes were ionic. According to the results obtained from the elemental analysis and spectral measurements were complexes of Sn(II), Sn(IV) and Co(II) tetrahedral geometry, while the complexes with Ni(II) and Cu(II) had a square planar geometry. The ligand LS2 and its complexes were examined against Staphylococcus aurous bacteria and Escherichia coli bacteria.","PeriodicalId":218143,"journal":{"name":"Al-Bahir Journal for Engineering and Pure Sciences","volume":"139 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135838641","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}

Nevertheless, by increasing the layer thickness, the resistivity decreases as well, resulting in greater current transport. The dip coating system was developed to prepare the ultra-thin ﬁ lm, it relied on a controller, stepper motor and some low-cost recycled materials. Thin ﬁ lms of ZnO were successfully deposited on indium tin oxide substrates. The effects of the dipping cycles were investigated. Dipping processes were applied several times (1, 2, and 3) for the same concentrations (0.1) M to obtain homogeneous thin ﬁ lms. X-ray diffraction showed that the structure of ZnO is hexagonal Wurtzite. The crystals were in the nanoscale size range as (19.18, 24.76, and 31.29) nm. As for the examination by FESEM, it was found that homogeneous layers formed when increasing the number of times of coating for the prepared thin ﬁ lms. High transmittance, decreasing in energy gap, and suitable surface resistance ZnO thin ﬁ lms were achieved. In the wavelength range of 190 e 1100 nm, the thin ﬁ lms had an optical transmittance of up to 87%. The sheet resistance values were determined to be 19.202 U sq ¡ 1 indicating that the characteristics of ZnO thin ﬁ lms have improved. The dip coating device is designed to be easy to use, inexpensive and economic in terms of using the raw materials. This low-cost manufactured device contributes to scienti ﬁ c development for researchers who are unable to buy expensive devices that perform the same purpose and give the same results.","PeriodicalId":218143,"journal":{"name":"Al-Bahir Journal for Engineering and Pure Sciences","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134462728","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}
