Consequently, there exists a pressing imperative to explore methodologies aimed at the elimination of hazardous substances from polluted water. Among the array of extant approaches, membrane-based techniques emerge as notably efficacious for mitigating pollutants, specifically heavy metals, in water systems. The elimination of mineral contaminants from water holds paramount significance for fostering a hygienic environment and safeguarding human health. Polymeric membranes offer an energy-efficient approach to water purification, yet they encounter fouling issues during filtration. Surface modification of the membrane is one avenue for mitigating fouling, aiding in the maintenance of elevated water productivity levels. The present investigation undertakes a comprehensive examination of outcomes derived from diverse experiments conducted over the preceding two decades, with the objective of identifying the most pertinent membrane filtration processes, accounting for varied contaminant profiles.","PeriodicalId":16821,"journal":{"name":"Journal of Physics: Conference Series","volume":"106 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142258148","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}

Elemental analysis; IR and 1H-NMR were used to determine the structures and mode of bonding, TGA, and DSC techniques were used to make thermal analysis for the prepared complexes. TGA was used to study the mechanisms of the thermal decomposition for florfenicol complexes. The prepared complexes are thermally stable and started to decompose after 200οC. Broido’s method was used to determine the activation energy for the prepared compounds, while thermal transitions and kinetic studies were carried out by differential scanning calorimetry technique (DSC). The antimicrobial activity of the complexes of florfenicol with different concentrations (0.005, 0.01, 0.02 μg/mL) was examined by the agar prolixity technique against common human pathogenic Staphylococcus aureus (Gram-positive) and Escherichia coli (Gram-negative). Comparatively, Nickel and Copper complexes showed a higher zone of inhibition against the tested pathogens. The antibiotic complexes were more active than the ligand itself for some breeds.","PeriodicalId":16821,"journal":{"name":"Journal of Physics: Conference Series","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142258154","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}

To maintain fluidity and stability during industrial applications of coal wastewater slurry, stabilizers play a crucial role. To promote the energy utilization of industrial wastewater, this article conducted a comparative study on different stabilizers for coal wastewater slurry. The results are as follows: (a) Compared with other stabilizers, xanthan gum makes the water separation rate of the coal wastewater slurry the lowest, and the slurry still maintained good stability after standing for 1 week and 1 month; (b) If the coal wastewater slurry requires a short storage time, the slurry properties with a blending ratio of 0.05% of xanthan gum will be the best; if the coal wastewater slurry requires a longer storage time, it can be made with a blending ratio of 0.10% of xanthan gum. The conclusion presented in this paper offers valuable insights for selecting stabilizers during the preparation of coal wastewater slurry.","PeriodicalId":16821,"journal":{"name":"Journal of Physics: Conference Series","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142199359","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}

To address the United Nations thirteenth Sustainable Development Goal (SDG) which is climate action, the stakeholders of Oman need to understand the carbon dioxide (CO2) emissions and compare the amount of CO2 with the emissions in neighbouring Gulf Cooperation Council (GCC) countries such as United Arab Emirates (UAE), Bahrain, Qatar, Kuwait, and Kingdom of Saudi Arabia (KSA). In this research, an attempt is being made to collect the CO2 emission for all these countries and show them on a web map using python programming language. The data ranging from year 1964 to 2021 is collected from CO2 and Greenhouse Gas Emissions in Comma Separated Values (csv) format. For each country, an approximate location for Capital in terms of Latitude and Longitude is taken from google maps. Using folium library of python, these locations and CO2 emission for a particular year is plotted on google map Application Programming Interface (API). The findings reveal that Oman’s CO2 emissions from fossil fuels and industry in 2022 year is 72 million tonnes which is relatively lower when compared to those of smaller GCC countries such as Qatar (101 million tonnes) and the UAE (244 million tonnes). Nonetheless, a gradual upward trend of 12 million tonnes of CO2 emissions has been observed in Oman between the years 2019 to 2022. The python program provides an easy way to visualise the CO2 emission heatmap without the need of any proprietary software or program.","PeriodicalId":16821,"journal":{"name":"Journal of Physics: Conference Series","volume":"33 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142269230","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}
