Fluorine Adsorbents in Water. A Compilation
Abstract: Fluorine constitutes 0.08% of the earth crust. This chemical element is found in the air, soil, rock, and water. Fluoride finds industrial application in the production of ceramics, pesticides, aerosol propellants, and refrigerants. Within the field of medicine, fluorides have been employed for several decades in the prevention of dental cavities. Scientific evidence affirms that fluoride is often harmful to health. Water is a very important vector of fluoride, which …

Cytotoxic and Antigenotoxicity Activity of Hibiscus sabdariffa Extract Against Tobacco Smoke Extract in Allium cepa Cells
Abstract: The present study was objective to determine whether and to what extent Hibiscus sabdariffa (H. S) extract can reduced the genotoxic damage by Cigarette smoking extract on Allium cepa cells. For this purpose, we used onion bulbs were treated with %2 cigarette smoking extract for 12 h, then treated with concentrations 0.1, 0.01, 0.001 mg/ml of H.s extract for other 12 h; while negative control in water and positive control …

Synthesis and Characterization of Biodiesel from Waste Cooking Oils by Acid and Base Catalysis
Abstract: In this study, biodiesel was synthesized by the transesterification reaction involving methanol and triglyceride obtained from waster cooking oil (WCO) in a laboratory scale reactor. Different concentrations of catalysts such as sulfuric acid (H2SO4) and potassium hydroxide (KOH) were employed in the reactions. The feedstock samples were gathered from neighbourhood eateries in Ghana's Cape Coast metropolis. Investigations were done into how variables including temperature, reaction time, methanol/WCO ratio, and catalyst …

Response Surface Methodology for Improving Quicklime Production from Eggshell
Abstract: This study aimed to enhance the characteristics of quicklime by creating practical models based on experimental data. The research focused on analyzing the impact of three key factors during the calcination process: temperature, duration, and the size of eggshell particles. Two process models for RSM models were successfully created and validated. The residual errors between the actual values and the predicted values in the modeling validation runs were less than …

Synthesis, Characterization and Antibacterial Activity of Chalcone Derivatives
Abstract: Chalcone derivatives were produced by the Claisen-Schmidt condensation of aromatic aldehydes with methyl ketones. Chalone derivatives are valuable species as they belong to keto-ethylenic components. Chalcone is a one-of-a-kind template that is linked to a variety of biological processes. 2-hydroxy-2,5- dichloro acetophenon (1) were synthesized by Fries migration and condensed with aromatic aldehyde to produce the new chalcone derivatives (2a-e). The new 1-(2-hydroxy-3,5-dichlorophenyl)-aryl-prop2-ene-1-ones (2a-e) (chalcones) were characterized using FT-IR and …

Occupancy of Al 3+ /Cr 3+ ions at B-sites in Ni-Zn-Cu ferrite system synthesized by sol-gel auto-combustion method
Abstract: Ferrites find extensive application in traditional electronic, electrical, and magnetic equipment and systems.The ferrite materials substituted with different cations have become most important because of their both fundamental and technological application. In our current research, we investigate the impact of Al3+ and Cr3+ ions on the properties of nano- sized Ni0.7Zn0.2Cu0.1Fe2O4 ferrites created using the sol-gel auto-combustion process. We employ various analytical techniques, including XRD, SEM, FTIR, ESR, VSM, and …

Synthesis Spectral Characterisation and Biological Activity of Hetero-cyclic Compound of 2-Imidazolones
Abstract: Because of the wide range of applications for 2-imidazolones, they have achieved enormous importance in human life. Although there are other methods for generating 2-imidazolones, the bulk of them required an 8 to 10 hour reflux period. As a result, the suggested study was done to develop a simple process for the synthesis of 2-imidazolones and to improve product yield by using Zeolite as a catalyst. The work described here …
