On one hand, the deployment of radiotherapy is one of the most acceptable modalities for malignancy treatment, for the reason of its ability to kill cancer cells. Equally, one is scared of the exposure to man-made emissions in the form of nuclear disasters or related to any form of hilarious power generation during the war. It is rational to facilitate the body enduring small intensity of emissions without any marked side effects. However, there are countless detrimental side effects of being exposed to elevated levels of radiation. These harmful side effects form an underlying fear in the general public in understanding the actual mechanism and concrete remediation of radiation exposure. The present study investigates in detail the principles of radiation safety and how different types of radiation emissions affect the human body when exposed at different levels of their intensity. Furthermore, it is also conferred how cellular mutations are originated in different organs and body systems due to different levels of radiation exposure and also the potential of organisms to develop resistance (threshold limit) to counteract harmful effects of radiation.","PeriodicalId":21012,"journal":{"name":"Research Journal of Chemistry and Environment","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135164844","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}

Herein, a novel design of a double-chamber hybrid photobioreactor is proposed, featuring low-cost components including a 3-W centrifugal pump and recyclable plastic modules for its solar flank, as well as derivatives from tubular and membrane photobioreactors. The hybrid photobioreactor exhibits reasonable hydrodynamic performance with a circulation time of 120 seconds and a mixing time of 38 seconds. A side-by-side runthrough of Chlorella vulgaris cultivation with the novel hybrid photobioreactor and a standard open pond system was done to compare growth rates and system performance under equal environmental conditions. Resulting measurements show that the hybrid photobioreactor produced a 34.87% comparatively greater amount of C. vulgaris by the tenth day of cultivation, demonstrating a significantly higher growth rate (P < 0.05). In contrast, wet-sludge lipid extraction processes show that the C. vulgaris culture grown in the open pond system held a substantially larger lipid accumulation than that of the hybrid photobioreactor, although the difference was not statistically significant (P > 0.05). The pilot-scale photobioreactor not only costed as little as the open pond system but also incurred 88.6% less expenses compared to a similarly designed bioreactor made of clear PVC material. Consequently, this project demonstrates the candidacy of the proposed low-cost hybrid photobioreactor design for microalgal biofuel production.","PeriodicalId":21012,"journal":{"name":"Research Journal of Chemistry and Environment","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135164841","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 characterization was performed using SEM, XRD and EDX analysis which demonstrated the effects of nano-sized Cu2Zr3O7 particles on the crystallinity and surface morphology of the fillers and elemental analysis using the EDX method. The dielectric behavior of the composite was investigated using an Impedance Analyzer. The composite's tensile strength was increased as evidenced by 34% increase in Young's modulus compared to blank HDPE for the sample with 1.5 wt% nanofiller loading. The results indicated that the dielectric constant increased as the frequency decreased, with higher values observed at 10 MHz. However, this trend was less pronounced at reduced filler loadings. The loss tangent initially dropped abruptly and then gradually as the frequency increased between 4 Hz and 1 MHz. The addition of Cu2Zr3O7 nanoparticles resulted in increased conductivity at higher frequencies compared to pure HDPE, with no significant frequency dependency observed at lower frequencies.","PeriodicalId":21012,"journal":{"name":"Research Journal of Chemistry and Environment","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135164839","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 individual Ag-CuO and Ag-ZnO nanocomposites were synthesized by using chemical precipitation method. The resulting particles were characterized by using UV-Visible, FTIR, XRD and SEM. The optical properties and band gap measurements were explored by UV-Visible spectroscopy. FTIR spectrum of the prepared nanocomposite revealed the presence of vibrational modes which were related to the Cu-O, Zn-O. The XRD analysis confirmed the structural purity of synthesized nanocomposites and the estimated crystallite size is 31.93 nm and 26.62 nm for Ag-CuO and Ag-ZnO nanocomposites respectively. The morphological features were explored by SEM analysis with deposition of Ag nanoparticles on the surface of metal oxide nanoparticles. The antibacterial activities of synthesized nanocomposites were tested on bacteria strains such as Escherichia coli (Gram -ve) and Staphylococcus aureus (Gram +ve) respectively through well diffusion method. The synthesized nanocomposite shows the higher efficacy against E.coli with an average diameter size of 17 mm zone of inhibition. This result suggests that Ag-CuO and Ag-ZnO nanocomposites can be used effectively against microbial growth. Therefore, the synthesized nanocomposite may be promising for the antibacterial agent in pharmaceutical applications.","PeriodicalId":21012,"journal":{"name":"Research Journal of Chemistry and Environment","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135164834","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}
