Abstract: Dyes are an integral part of the health of clothing, food, and other organisms, but the dyes commonly contain added corrosive chemicals that can cause corrosive effects on prolonged contact with the dye. In addition, the chemicals contain pollutants that pollute the water supply. saurashtra area is famous for living industries and the above-mentioned people are always concerned about the people.[1] So, this project proposes a solution by isolating the material of Kauri which is already prominent in the ancient night knowledge system but due to the invasion of aliens and the neglect of the society, it is visible today. he projects addresses the Sustainable Development Goals-2030, Goal 3: Health and Welfare, Goal 4: Mathematical Education, Goal 8: Skills and Economic Growth, and Goal 12: Responsible Consumption and Production. 2023-01-01T00:00:00Z http://10.9.150.37:8080/dspace//handle/atmiyauni/901 Title: To Study The Synthesis Of Schiff-Base Derivatives Authors: Ramani, Haresh A.; Sagar, Jaydeep M.; Sakariya, Tejas P.; Singh, Sagar S.; Khatrani, Sunnykumar V. Abstract: Schiff base is a condensation product of primary amine and carbonyl compounds for gain the importance day by day in the present scenario. Schiff base is the compound containing azomethine or amine (-C=N-) functional group and it is found to be an inconstant pharmocophore for the design and development of some bioactive compounds. Schiff base are some of the most widely used organic compounds. They are used as pigments and dyes, catalysts, intermediates in organic synthesis, and as polymer stabilizer. Schiff base have also been shown to exhibit a broad range of biological activities, including antifungal, antibacterial, ant malarial, ant proliferative properties. Imines or azomethine groups are present in various natural, natural-derived, and non-natural compounds. The amine groups present in such compounds has been shown to be critical to their biological activities. In this review we present the general approaches to the synthesis of Schiff base. We also highlight the most significant example of compounds belonging to this class, which exhibit anti-malarial, antibacterial, antifungal and antiviral activities to have been reported in the literature. The relationship between Schiff base and other pharmacological activities, such as ant proliferative activities, are not included in this review. 2023-01-01T00:00:00Z http://10.9.150.37:8080/dspace//handle/atmiyauni/900 Title: Synthetic transformation of lower cost feedstocks to biodiesel using novel solid acid catalyst Authors: Bakori, Utam R.; Baldha, Dhruvin G.; Chhotala, Gautam R. Abstract: The production of biodiesel from non-edible oils and fats is an attractive option to reduce dependence on fossil fuels. This study focuses on the use of novel solid acid catalysts for the conversion of lower cost feedstocks to biodiesel. The catalyst PNAS-Si synthesized by impregnating silica with sulfonic acid groups and evaluated for their performance in biodiesel production. Biodiesel production from waste palm oil involves a transesterification reaction using PNAS- Si catalyst. The process can be optimized by controlling various parameters such as temperature, reaction time, and molar ratio of reactants [1]. The results showed that the solid acid catalyst PNAS-Si significantly improved the conversion efficiency and selectivity of biodiesel production from non-edible oils and fats. Then Synthesized biodiesel is characterized through FT-IR and 1H-NMR techniques. The study concludes that the use of these catalysts has great potential for the development of sustainable and economically viable biodiesel production processes [2]. 2023-01-01T00:00:00Z http://10.9.150.37:8080/dspace//handle/atmiyauni/899 Title: Synthesis And Characterization Of Metal Super-Hydrophobic Surfaces Authors: Kansagara, Sanket; Kapadiya, Yash; Karavadara, Raju; Kathiriya, Yashaval Abstract: In this our dissertation work we prepared superhydrophobic surface on zinc, Aluminum and copper metals surfaces and on fabric surface. On metals surface we created superhydrophobic coating by etching and hydrothermal coting process. In this process we use KOH and NaOH use as etching solutions which creates microstructure on metal surfaces. Our coating material was stearic acid and lauric acid. After coating contact angles of surface with water droplets was measured with the help of image J capture software. Higher contact angle was 159.57° on aluminum surface by etching process, which shows superhydrophobic characteristics. Our Another work on fabric surface. In coating on fabric surface our coating method is novel and not reported yet. In this process contact angle is 153.56° degree, which shows superhydrophobic characteristics. 2023-01-01T00:00:00Z
