Electrical energy is used to drive a non-spontaneous redox reaction in an electrolytic cell battery, which is composed of an electrochemical cell. The process of breaking down chemical compounds through electrolysis is frequently utilized, and it is derived from the Greek word lysis, which means to disintegrate. The electrolytic cell is composed of an electrolyte, two electrodes (one cathode and one anode), and three other components. Water or other solvents are typically used to make an electrolyte, which is a solution that contains dissolved ions. The purpose of this study is to test, analyze, and construct an electrolytic cell battery using various electrolytic solutions, salt-water concentrations, and the integration of fuel cells and electrodes. The research is designed to be experimental and relies on descriptive analysis to assess it. The design focused on the finding the optimal combination of electrode limited to zinc, copper, and aluminum (soda can), different electrolyte, type of connection of the fuel cells and the different concentration of saline solution used in order to provide optimum energy output. According to the data gathered and analyzed, the Zinc-Copper electrode produces an average voltage of 0.705 V per cell. Saltwater electrolyte produces the most effective results based on its cost effectiveness. When saline solution is 30% concentrated, the optimal voltage output is achieved, and fuel cells perform their best when connected in series. Using this parameter, twenty fuel cells are constructed that can produce 14.10 V without any load. The voltage was 7.57 V and the current was 1.1 A when connected to a DC lighting load that has a 12V power supply.

Kinetic, equilibrium and, thermodynamic studies of the bleaching of crude groundnut oil at optimized conditions were carried out using activated rice husk as an adsorbent for the bleaching process. The efficiency of bleaching was estimated by measuring the absorbance using a double- beam spectrophotometer at a wavelength of 450nm. The effects of adsorbent dosage, bleaching temperature and, contact time on the bleaching efficiency were studied. A directly proportional relationship was found between dosage and contact time and the bleaching efficiency while a bell curve was discovered for temperature increase. The surface area of the rice husk increased from 150.32 to 1450.32 m2/g while the pore volume decreased from 0.15524 to 0.12844 cm3/g after activation which was determined via a Brunauer-Emmet-Teller (BET) analysis and the results further validated by the Scanning Electron Microscopy (SEM) images obtained. The kinetic data of the bleaching process were best described by the pseudo-second order kinetic model while the equilibrium adsorption isotherm analysis showed that the results from the Temkin isotherm were the most significant. The thermodynamic study revealed that the adsorptive bleaching process is feasible, spontaneous and, exothermic with a decrease in entropy. The enthalpy value also showed that the adsorption process is predominantly physisorption. This study has revealed that an effective adsorbent can be produced from rice husks under optimized process conditions.

The fascinating behavior of charge transport layer in organic and inorganic perovskite solar cells has piqued the interest of designers of semiconductor SnO2 nanoparticles (PSC). The goal of this research is to look at several techniques for manufacturing SnO2 films for use as charge transport layers in PSC. To comprehend the link between the attribute of nanostructured SnO2 films and the efficiency of solar cells, special attention is devoted to the production and properties of the SnO2 thin films. The spin-coating deposition of SnO2 nano fluids generated via surface modification of nano-colloids composed of SnO2 has been one of the key techniques for obtaining SnO2 layers. It has also been reported that preparing SnO2 nanoparticles using Tin (IV) salts results in a high-quality SnO2 film. Light-to-electricity conversion efficiency of about 25.5% has been claimed in many PSC papers [1]. One benefit of adopting SnO2 materials is that they have substantially greater conductivity than TiO2. This work also discusses the production of SnO2 nanoparticles, a different method of generating SnO2 charge transport materials that may be accomplished by the process of freeze-drying precursors known as Tin (IV). SnO2 crystal formation may be regulated at temperatures as low as 700C.

Water is a universal solvent on earth and sources such as wells, rivers, springs, boreholes, and other freshwater bodies typically serve as a pathway for contaminants to enter the ecosystem while also supplying water for domestic and drinking purposes. The activity concentrations of radionuclides in borehole water in Igbajo town were assessed using gamma-ray spectroscopy, so as to effectively determine the degree of radiological risk to the environment and its inhabitants, the outcomes were used to calculate all the radiological impact parameters. The activity concentrations obtained for 40K, 238U and 232Thranged from 7.25±0.60 to 62.15±4.48Bq.L–1; 3.08±0.45 to 15.24±3.07 Bq.L–1and 1.08±1.10 to 17.75±1.59 Bq.L–1 and with average values of 23.12±1.59 Bq.L–1, 6.27±2.01 Bq.L–1 and 7.01±0.89 Bq.L–1 respectively. The Annual Effective Dose (AED) for ingested radionuclide in drinking water for an adult was1.4872 μSv.yr–1. The Radium Equivalent Activity Index, Raeq obtained was 34.9186 Bq.L–1. The estimated hazard indices Hint and Hext were 0.04876 and 0.06574 respectively. The Excess Lifetime Cancer Risk, ELCR (x10–6) was 5205.15. With a lifetime expectancy of 70 years, this high value suggests that there is a high chance of developing cancer.The value of the Annual Gonadal Equivalent Dose, AGED in the water was 55.9175μSv.yr–1. The estimated Gamma Index, Iγ was0.1273 mSv.yr–1. There is a significant health hazard to the environment and people living in the area owing to the radioactivity contents and radiological impact parameters. Hence, the need for urgent attention and means to prevent hazards which the overdose could cause.

Chromium is a toxic heavy metal that can pollute water from industrial and agricultural activities. Adsorption is a promising method for removing chromium from wastewater, and walnut shell is a sustainable and abundant biomass that can be used to produce biochar for adsorption. This study compares the effectiveness of walnut shell and walnut shell biochar for chromium removal from wastewater using adsorption. The effects of various parameters on chromium adsorption, such as pH, biochar dosage, and contact time, are investigated. The results show that both walnut shell and walnut shell biochar are effective adsorbents for chromium removal. However, walnut shell biochar exhibits a higher adsorption capacity and faster adsorption kinetics than walnut shell. The findings of this study suggest that walnut shell biochar is a promising adsorbent for chromium removal from wastewater. It is a sustainable and low-cost material that can be used to develop effective and efficient wastewater treatment systems. The kinetics of Cr adsorption will examine using pseudo-first-order, pseudo-second-order, and adsorption isotherms. The results demonstrated that the adsorption of Cr onto WS and BC followed pseudo-second-order kinetics, suggesting chemisorption as the rate-limiting step.

NOX emissions are a health hazard, and are increasingly regulated in cars. NOx also contributes to the formation of acid rain and the eutrophication of ecosystems. Nitrogen oxides are a family of molecules including nitrogen monoxide (NO) and nitrogen dioxide (NO2). These gases are formed in the engine during high-temperature fuel combustion, and play a role in the formation of fine particles in ambient air. In this article, the aim is to determine the nitrogen content of gasoline samples taken at four gasoline stations of the most representative groups in terms of distribution of light petroleum products in order to assess the environmental impact due to greenhouse gas emissions resulting from the use of gasoline by vehicles and to reduce the nitrogen content in the form of nitrogen oxides NOx. After an introduction, we presented the material and the method used, followed by the results of our analyses and a discussion of the results obtained before concluding.

Rice bran, a byproduct of rice milling, is a valuable ingredient in animal feed formulations, particularly poultry feed, due to its high energy content, nutritional benefits, and ability to meet bird protein requirements. Rice bran, analyzed according to AOAC standards, is rich in energy, protein, and minerals like calcium, phosphorus, and potassium, essential for poultry health. Its high-fat profile, with higher unsaturated fatty acids, has positive effects on poultry health, including improved egg quality, enhanced immune function, and reduced disease incidence.
Rice bran has a moisture content of 4.3338% and a crude fibre content of 16.3675%. It has a total ash content of 18.8126% and a crude fat content of 12.0354%, 12.3676%, and 12.6180%. The compositions of rice bran were compared favourably to commercial feed formulations for starter, grower, and finisher meals. The crude fat content is 12.0354%, 12.3676%, and 12.6180%, while the crude protein content is 26.2688%, 27.5813%, and 21.8906%. The carbohydrate contents are 41.2677%, 41.8456% and 49.4032% and the total ash content was measured at 10.4377%, 6.3672% and 4.4905%.
The rice bran's trace mineral composition includes calcium, magnesium, potassium, phosphorus, sodium, iron, and copper. Heavy metals like lead and cadmium are below the detection limit of the M5 Thermo Scientific atomic absorption Spectrometer. The anti-nutrient composition includes anthraquinones, phenolics, tannins, saponins, and phytic acid.
Rice bran in poultry feed formulations enhances nutritional needs and outperforms commercial feeds. In addition, to increase nutrient availability, it is necessary to add a phytase enzyme in order to break down phytic acid.

Plant-mediated synthesis of the nanoparticles has attracted significant interest because of their biocompatible properties. Bimetallic nanoparticles comprise two different types of metals that play a significant role in wastewater. Bimetallic nanoparticles possess a greater surface area, increasing their adsorption than monometallic nanoparticles. In this study, synthesis and the adsorption behaviour of Bi-Mg bimetallic nanoparticles and their removal efficiency toward heavy metals (cadmium, lead, zinc) from wastewater is observed. Synthesis of bimetallic nanoparticles by natural resources (plant extract) is more significant than conventional methods because they are environment friendly, reliable, nontoxic and least expensive. Plant extract obtained from biomass wastes like roots, flowers, leaves and fruit peels is composed of novel secondary metabolites like terpenoids, flavonoids and alkaloids that act as stabilizing and reducing agents. Different techniques like SEM, EDX and XRD were used to analyze the morphology, composition and size of synthesized nanoparticles. The removal of heavy metals depends on the pH, dosage of adsorbent and initial concentration of the metals. The results showed that the plant-mediated synthesized nanoparticles could act as an efficient adsorbent to remove heavy metals from wastewater.

Plant extract obtained from biomass wastes like roots, flowers, leaves and fruit peels is composed of novel secondary metabolites like terpenoids, flavonoids and alkaloids that act as stabilizing and reducing agents. Different techniques like SEM, EDX and XRD were used to analyze the morphology, composition and size of synthesized nanoparticles. The removal of heavy metals depends on the pH, dosage of adsorbent and initial concentration of the metals. The results showed that the plant-mediated synthesized nanoparticles could act as an efficient adsorbent to remove heavy metals from wastewater.","PeriodicalId":14371,"journal":{"name":"International Research Journal of Pure and Applied Chemistry","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136115352","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 new derivatives of thiazole based Schiff base of (1-(5-(2,3,4-trisubstitutedphenyl)-2-((4-nitrobenzylidene)amino)thiazol-4-yl)ethan-1-one (6) were synthesized by the treatment of 1-(2-amino-5-(2,3,4-trisubstitutedphenyl)thiazol-4-yl)ethan-1-one (4) and corresponding substituted benzaldehyde (5) in low cost easily available non flammable stable and ecofriendly solvent Polyethylene glycol-400 solvent medium. The reactions were performed in the good yield and less time. The structures of all synthesized compounds were established on the basis of elemental analysis, IR, NMR and Mass spectral data.

Hydraulic networks from groundwater are the resources most exploited by the population for their daily needs. These water tables are constantly under pressure from pollution caused by human activities. In the tropical zone, more particularly in Ivory Coast, very few studies have been carried out on glyphosate, aminomethylphosphonic acid (AMPA), glufosinate and metallic trace elements (ETM) in groundwater. This study aims to determine the level of vulnerability of groundwater by these compounds. The study covered the waters of thirteen boreholes with an average depth of 69.26 meters near the Abidjan region (5°25'0" N / 4°1'60" W ) and the analyzes were carried out using the chromatographic method with detection by spectrophotometry. The results revealed the presence of glyphosate in all the samples analyzed at average concentrations of: 0.12±0.02 µg/L (minimum) and 1.9 ±0.1 µg/L (maximum), all higher than the water potability threshold value (0.1 µg/L) defined by the WHO. As for ETM, they are present in these boreholes at high concentrations of: 39±2 µg/L (As), 130±3 µg/L (Pb), 80±1 µg/L (Cu), 73±3 µg /L (Ni), 200±3 µg/L (Zn) at FILTISSAC, 20±2 µg/L (Cr) at Vridi and 21000 ±200 µg/L (S) in the Koumassi borehole. The health risk linked to the consumption of groundwater by the population, according to the mathematical calculation model used, is not acceptable. This study deserves to be conducted throughout the national territory.
