Background: The ideal reaction conditions for the quantitative detection of phosphate in various natural water and detergent samples were carefully researched in order to produce and preserve the colored complex product. The blue complex was identified using a simple and accurate UV-VIS spectrophotometer with a maximum wavelength of 870 nm. Even though phosphate is an essential ingredient for the development of aquatic species, it is important to know exactly how much is present because an excess amount of phosphate can eutrophic water. Since detergents are one of the sources of phosphate in natural water, determining the concentration of phosphate in detergent samples is also essential. Materials and Methods: The method is based on the addition of sodium molybdate, which causes the interaction of orthophosphate with molybdate to produce an intense, stable, and water-soluble phosphomolybdate blue complex. Then, this combination is reduced using hydrazine hydrate in a sulfuric acid solution. Results: With a correlation coefficient of 0.9944, the system complies with Lambert-Beer's law at 870 nm in a concentration range of (0.05-9) ppm. Molar absorptivity was determined to be 12.16x103 L mol-1 cm-1 and Sandell's sensitivity was found to be 0.0156 g cm-2. Water samples were collected from Warte, Choman, Jundeyan, and Bexal in Kurdistan's vicinity of Soran. Further, detergent samples that were obtained from the market and their phosphate level were examined. The Bexal waterfall had the lowest concentration of phosphate, 0.18 ppm, while the Warte and Jundeyan water samples had the highest concentrations, 3.31 ppm, and 3.04 ppm, respectively. Moreover, similar phosphate concentrations in the two detergent samples were discovered to be at 20.43 and 24.76 ppm. Conclusion: The molybdenum blue reaction has been successfully employed to provide a sensitive and quick measuring method to quantify the phosphate content in various water and detergent samples using UV-VIS spectrophotometry by applying the right reaction conditions and reagent quantities.
背景:& # x0D;为了生产和保存有色络合产物,对各种天然水和洗涤剂样品中磷酸盐定量检测的理想反应条件进行了研究。用紫外-可见分光光度计对蓝色配合物进行了简单准确的鉴定,最大波长为870 nm。尽管磷酸盐是水生物种发育的基本成分,但确切知道存在多少是很重要的,因为过量的磷酸盐会使水富营养化。由于洗涤剂是天然水中磷酸盐的来源之一,因此测定洗涤剂样品中磷酸盐的浓度也是必不可少的。 材料与方法: 该方法是基于添加钼酸钠,这使得正磷酸盐与钼酸盐相互作用,产生强烈的,稳定的,水溶性的磷钼酸盐蓝色配合物。然后,在硫酸溶液中用水合肼还原这种组合。 结果:& # x0D;相关系数为0.9944,在870 nm处,浓度范围为(0.05-9)ppm,符合Lambert-Beer定律。测定其摩尔吸光度为12.16 × 103 L mol-1 cm-1,桑德尔灵敏度为0.0156 g cm-2。从索兰附近库尔德斯坦的Warte、Choman、Jundeyan和Bexal采集了水样。此外,洗涤剂样本,从市场获得和磷酸盐水平检查。Bexal瀑布的磷酸盐浓度最低,为0.18 ppm,而Warte和Jundeyan水样的磷酸盐浓度最高,分别为3.31 ppm和3.04 ppm。此外,发现两种洗涤剂样品中的磷酸盐浓度相似,分别为20.43和24.76 ppm。结论:& # x0D;本文成功地利用钼蓝反应提供了一种灵敏、快速的紫外-可见分光光度法测定各种水和洗涤剂样品中磷酸盐含量的方法。

Background: The quest for improving the efficiency of solar cells has garnered considerable attention in numerous scientific investigations. One promising approach involves utilizing plasmons generated by metal nanoparticles to enhance the performance of photovoltaic solar cells. Materials and Methods: High-purity gold nanoparticles (AuNPs), silver nanoparticles (AgNPs), and a combination of both were synthesized using pulsed laser ablation in distilled water. Subsequently, these nanoparticles were deposited onto silicon (Si) substrates and pre-existing Si homo-junction photovoltaic cells. Results: The optical analysis of the prepared nanoparticle suspension revealed distinct plasmonic bands located at approximately 400 nm and 523 nm wavelengths for AgNPs and AuNPs, respectively. In the case of the AuNPs:AgNPs mixture, two plasmonic bands were observed, corresponding to the presence of both types of metal nanoparticles. The X-ray diffraction (XRD) analysis of the deposited nanoparticle samples on Si wafers demonstrated a polycrystalline structure for all samples. Scanning electron microscopy (SEM) imaging displayed uniformly distributed spherical Au nanoparticles on the substrate, while AgNPs exhibited some aggregations. Conclusion: The photovoltaic (PV) solar cells demonstrated an enhanced performance, attributed to the ability of the plasmonic nanoparticles to facilitate increased light absorption or enhance surface conductivity. The combination of silver and gold particles holds promise for solar surface coating, further optimizing the cells to capture a greater amount of solar radiation within their plasmon peaks. This study highlights the potential of plasmonic nanoparticles to enhance the efficiency of previously prepared PV cells.
背景:在许多科学研究中,对提高太阳能电池效率的追求已经引起了相当大的关注。一种很有前途的方法是利用金属纳米颗粒产生的等离子体激元来提高光伏太阳能电池的性能。材料与方法:采用脉冲激光烧蚀法在蒸馏水中制备了高纯金纳米粒子(AuNPs)、银纳米粒子(AgNPs)及其组合。随后,这些纳米颗粒被沉积在硅(Si)衬底和已有的硅同质结光伏电池上。结果:制备的纳米颗粒悬浮液的光学分析显示AgNPs和AuNPs分别在约400 nm和523 nm波长处有明显的等离子体带。在AuNPs:AgNPs混合物的情况下,观察到两个等离子体带,对应于两种类型的金属纳米颗粒的存在。在硅晶片上沉积的纳米颗粒样品的x射线衍射(XRD)分析表明,所有样品都具有多晶结构。扫描电子显微镜(SEM)成像显示,在衬底上均匀分布的球形Au纳米粒子,而AgNPs则出现了一些聚集。结论:由于等离子体纳米粒子能够促进光吸收或增强表面导电性,光伏(PV)太阳能电池的性能得到了增强。银和金粒子的结合有望用于太阳表面涂层,进一步优化电池,在其等离子体峰内捕获更多的太阳辐射。这项研究强调了等离子体纳米粒子在提高先前制备的光伏电池效率方面的潜力。

Background: This research was conducted to estimate the activity concentration level of 40K, 238U and 232Th in soil and cassava and determine the transfer factor from soil to cassava in Ughelli North, Delta State, Nigeria. Materials and Methods: These were examined using gamma spectrometry and considering a lead-shielded 3 x 3inch coaxial type Sodium Iodide Thallium doped detector. Results: The mean activity concentrations of 40K, 238U and 232Th are 45.49 ± 4.28 BqKg−1, 3.15 ± 0.77 BqKg−1 and 0.56 ± 0.06 BqKg−1 respectively in soil samples and 134.08 ± 11.59 BqKg−1, 3.89 ± 0.93 BqKg−1 and 0.81 ± 0.09 BqKg−1 correspondingly in cassava samples. The mean transfer factor of 40K, 238U and 232Th from soil to cassava are 3.44 ± 0.75, 1.94 ± 0.32 and 1.34 ± 0.54 respectively. Peak values of the TF were noted as 8.52 for 40K at U18, D18, 25.58 for 238U at U12, D12 and 5.71 for 232Th at U11, D11. Conclusion: The activity concentration of 40K, 238U and 232Th in the area are lower than the world average values. Consequently, it will not pose any radiological hazard if consumed. The high value of Transfer factor is attributed to the richness of the organic matter in the soil and may indicate high ability to transfer radionuclides in the soil to food crops but from the concentration information, these radionuclides present in the soil are low as well as annual effective doses. There is no radiological risk of ingestion.
背景:& # x0D;本研究旨在估算尼日利亚三角洲州Ughelli North地区土壤和木薯中40K、238U和232Th的活性浓度水平,并确定土壤向木薯的转移因子。材料与方法: 使用伽马能谱法并考虑使用铅屏蔽的3 x 3英寸同轴型碘化钠铊掺杂探测器。 结果:& # x0D;土壤样品中40K、238U和232Th的平均活性浓度分别为45.49±4.28 BqKg−1、3.15±0.77 BqKg−1和0.56±0.06 BqKg−1,木薯样品中40K、238U和232Th的平均活性浓度分别为134.08±11.59 BqKg−1、3.89±0.93 BqKg−1和0.81±0.09 BqKg−1。40K、238U和232Th从土壤到木薯的平均传递因子分别为3.44±0.75、1.94±0.32和1.34±0.54。在U18、D18时,40K的TF峰值为8.52,U12、D12时238U的TF峰值为25.58,U11、D11时232Th的TF峰值为5.71。结论:& # x0D;40K、238U和232Th的活度浓度均低于世界平均水平。因此,食用后不会产生任何放射性危害。转移因子的高值归因于土壤中有机质的丰富,可能表明土壤中放射性核素向粮食作物转移的能力强,但从浓度信息来看,土壤中存在的放射性核素较低,年有效剂量也较低。不存在误食的辐射风险。
