The samples for both groups were produced using the hand-layup method. The samples were prepared in accordance with the specifications, and a vertical machine was used to carry out the drilling operation. For a total of 20 experiments per group with a pretest of G-power 80%. The sample’s MRR was assessed and compared. independent t-tests were performed on the MRR using the statistical software program. The average MRR for group 1 that is epoxy (90%)/fiber (5%)/nanocarbon particles (5%) was 0.37415 mm 3 /sec, compared to 0.11860 mm 3 /sec for group 2 (plain epoxy). Based on the outcomes of the independent t-test statistical analysis, it is determined that the mean variance of MRR between groups 1 and 2 is different (significant of p = 0.00, which is p less than 0.05). Hence identified a significant difference between the two groups considered. Within the constraints of this study, it is noticeable that the addition of reinforcements like sustainable areca fiber and nanocarbon particles has a significant effect on MRR improvement.","PeriodicalId":36802,"journal":{"name":"NanoWorld Journal","volume":"31 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139323733","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 study compares the results of a solar still with and without nanoparticles to determine the influence of nanoparticles on the still’s performance. The results of the investigation should assist in developing more sustainable technology for converting saltwater to freshwater. The research was conducted using two groups: group 1, which used a standard solar still without nanoparticles, and group 2, which used a modified solar still with nanoparticles. A total of 40 samples were included in this research, with 20 samples in each group. The data obtained from the experiments and sample size were analyzed using SPSS (Statistical Package for the Social Sciences) software. Testing was done on the samples in the experimental group and control group, and the re-sults were compared. The samples in the experimental group with nano particles showed higher efficiency than the control group without nanoparticles. This is less than that of the still with ordinary water, and they are much better than carbon nanotubes and other nanofluids. The mean volume of clean water produced by groups 1 and 2 was contrasted using the independent t-test samples. An independent sample t-test was performed on the obtained results using the statistical software SPSS and the significance was ensured by the obtained (two-tailed) test p-value of 0.000 (p < 0.05) for developing mathematical models to optimize efficiency and increase the cumulative production of pure water. The daily yield, evaporation, and condensation rates of the solar still have significantly increased with the addition of nanoparticles to the base fluid. When introduced to the base fluid, Al 2 O 3 nanoparticles with a 0.3% concentration can boost productivity by up to 33.1%.","PeriodicalId":36802,"journal":{"name":"NanoWorld Journal","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139323913","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 manganese and cobalt were doped using the sol-gel method to prepare the composite material. Gradual addition of ethanol was done to remove negative ions from the composite. The illumination characteristics of the Mn-Co composite material were evaluated using XRD (X-ray diffraction), SEM (Scanning electron microscope), and UV-Vis (Ultraviolet-Visible) testing methods. Two groups were selected for the investigation of the UV-Vis absorption spectrum: Group 1 - Halogen at the activation temperature of 1000 °C, and Group 2 – Mn-Co composite material at the peak activation temperature of 1000 °C. Each group consisted of 20 samples, determined based on a pretest power of 80%, a probability value of 0.05%, and a confidence interval (CI) of 95%. A complete of 2 specimens were divided into a pair of teams with G-power of 80. The research findings indicated that the particle size of the Mn-Co composite material increased with the rise in temperature, and the peak absorbance wavelength decreased with increasing particle size. The results revealed a statistically significant difference between the two groups, with a p-value of 0.000 (p < 0.05). The analysis focused on examining the crystal structure of the composite material, phase purity, and optical properties. The band gap (eV) (0.7370 mm³/sec) of Mn-Co nanoparticles mean was found to be 0.3568 mm³/sec, which is higher than that of normal illumination. This study concluded that the Mn-Co composite material provides enhanced illumination compared to halogen material, which only provides normal illumination. The sol-gel method allowed for the efficient doping of manganese and cobalt in the composite, leading to improved illumination properties. The findings from this research could have significant implications in the development of advanced lighting materials for various applications.","PeriodicalId":36802,"journal":{"name":"NanoWorld Journal","volume":"39 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139323874","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}
