The bio-molecules inside the extract play an important role in converting nickel nitrate salt into nickel oxide nanoparticles. The prepared nickel oxide nanoparticles were characterized via different techniques such as X-ray Diffraction, fourier transform infrared spectroscopy, fi eld emission-scanning electron microscopy and ultraviolet e visible spectrophotometer. From X-ray diffraction results, the crystallite size of NiO NPs was estimated to be (39.7 nm). The fourier transform infrared spectroscopy exhibits intense two peaks at 594 cm ¡ 1 and 469 cm ¡ 1 which indicates the formation of NiO NPs. In addition, the energy band-gap calculated by Tauc ' s formula was ~2.89 eV. Finally, The antibacterial activity study results detected that NiO NPs have the highest activity against Staphylococcus aureus when compared to Escherichia coli . Thus, the present study exhibits good antibacterial activity, which may be explored in future clinical treatments.","PeriodicalId":218143,"journal":{"name":"Al-Bahir Journal for Engineering and Pure Sciences","volume":"133 9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125802593","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}

The purpose of this study is to discuss these points. The methodology can identify potential locations for asphalt concrete plants within a study area, considering the plants ' operation and capital costs and the costs of transporting raw materials to the plants and asphalt concrete to demand centers. Matrix Laboratory (MATLAB) software have been used to program the methodology. Thismethodology has been applied to Karbala using actual data. The methodology ' s output identi fi es the optimal locations and sizes of asphalt concrete plants in Karbala. There are two optimal locations for asphalt concrete plants B and D; their total size is 80 tons per hour and 800 tons per hour, respectively. This is adequate to supply Karbala ' s asphalt concrete demand to 2032.
