Primary goal of this work is to examine rate of material removal rate (MRR) during VMC (Vertical machining center) machining of inventive epoxy composites supported with sustainable natural fiber (areca) (5%) and nanocarbon particles made of tamarind seeds (5%) in comparison to plain epoxy. 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.
这项工作的主要目的是研究在立式加工中心（VMC）加工过程中，与普通环氧树脂相比，添加了可持续天然纤维（红茶）（5%）和罗望子纳米碳颗粒（5%）的创新型环氧树脂复合材料的材料去除率（MRR）。两组样品均采用手糊法制作。样品按照规格要求制备，并使用立式机器进行钻孔操作。每组共进行 20 次实验，预试 G 功率为 80%。对样本的 MRR 进行评估和比较。使用统计软件程序对 MRR 进行独立 t 检验。第 1 组（环氧树脂（90%）/纤维（5%）/纳米碳颗粒（5%））的平均 MRR 为 0.37415 毫米 3 /秒，而第 2 组（普通环氧树脂）为 0.11860 毫米 3 /秒。根据独立 t 检验统计分析结果，确定第 1 组和第 2 组之间的 MRR 平均方差不同（显著性 p = 0.00，即 p 小于 0.05）。因此，两组之间存在明显差异。在本研究的限制条件下，可以明显看出，添加可持续红茶纤维和纳米碳颗粒等增强材料对提高 MRR 有显著效果。

This research aims to investigate the effectiveness of using Al 2 O 3 (Aluminum oxide) nanoparticles to improve single-basin solar still performance in purifying saltwater into freshwater. 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%.
本研究旨在调查使用 Al 2 O 3（氧化铝）纳米粒子改善单池太阳能蒸馏器将咸水净化为淡水的性能的有效性。研究比较了使用和不使用纳米颗粒的太阳能蒸馏器的结果，以确定纳米颗粒对蒸馏器性能的影响。调查结果将有助于开发更可持续的技术，将盐水转化为淡水。研究分两组进行：第一组使用不含纳米颗粒的标准太阳能蒸馏器，第二组使用含纳米颗粒的改良型太阳能蒸馏器。研究共包括 40 个样本，每组 20 个样本。使用 SPSS（社会科学统计软件包）软件对实验数据和样本量进行了分析。对实验组和对照组的样本进行了测试，并对结果进行了比较。含有纳米颗粒的实验组样品的效率高于不含纳米颗粒的对照组样品。与使用普通水的蒸馏水相比，纳米颗粒蒸馏水的效率要低，而与使用碳纳米管和其他纳米流体的蒸馏水相比，纳米颗粒蒸馏水的效率要高得多。使用独立样本 t 检验对第 1 组和第 2 组产生的净水的平均体积进行对比。使用统计软件 SPSS 对所得结果进行了独立样本 t 检验，所得（双尾）检验 p 值为 0.000（p < 0.05），确保了检验的显著性，以便开发数学模型，优化效率并提高纯水的累积产量。在基液中加入纳米颗粒后，太阳能蒸发器的日产量、蒸发率和冷凝率均显著提高。在基液中加入 0.3% 浓度的 Al 2 O 3 纳米粒子后，生产率可提高 33.1%。

The objective of this study was to compare the illumination properties of halogen with a manganese cobalt (Mn-Co) composite material using a novel sol-gel method. 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.

Heavy metals are found in the effluents of many industrial units. The applicability of Moroccan natural phosphate from Benguerir (NPB) and Khouribga (NPK) regions can remove some heavy metals from water. This approach is considered benefic, inexpensive, and very effective for the treatment of contaminated waters. The raw samples of NPB and NPK are mainly composed of carbonated fluorapatite (FAP) associated with some impurities such as SiO 2 and CaF 2 . The heat treatment of these materials at 600 °C, 800 °C, and 1000 °C results in a single crystalline phase of phosphosilicate apatite. First, the adsorption efficiency of the dried phosphates depends on their mineralogy on the nature of the metal (Pb 2+ , Cd 2+ , Zn 2+ , and Cr 3+ ) in the order Pb 2+ > Cr 3+ > Cd 2+ > Zn 2+ . After treatment at 600 °C and 800 °C, the adsorption efficiency of the selected NPB sample was tested against Cr 3+ and Cd 2+ ions and it was slightly better compared to the raw sample. Therefore, NPB heat-treated at 600 °C can be considered a stable adsor-bent and depollution agent for wastewaters.
