Energy Generation using Artificial Speed Bump Based Compressed Air Storage Mechanism for Road Side Automatic Street Light Applications Ganesh R, Suresh K P, Nalini N, Senthilkumar M Proceedings 1st International Conference on Intelligent Technologies for Sustainable Electric and Communications Systems Itech Secom 2023, 2023 Energy consumption is unavoidable in man's daily life. Energy needs to be transformed from one form to another in order to accomplish any work in life. In the present scenario, green energy is currently in demand. The way that energy used is a sign of how well a country is doing economically. Information displays that the majority of energy used comes from traditional energy sources, which are limited and include fossil fuels, gas, and oil. They are harming our environment by burning fossil fuels. With the available conventional energy supplies, it is challenging to meet the demand. Therefore, using green or non-conventional energy may be the greatest option to meet the current demand. The goal of this work is to create a speed break electricity generator that operates the capacity for energy of a heavy vehicle on a speed breaker that energy can then store in the form of compressed air is kept on hand for storage and used for a variety of tasks like street light, traffic signal etc. in smart city applications. We described the mechanism for compressing air in store tanks and generating electricity from compressed air at various stages of the project's development.
Synthesis and Spectral Studies of Piprazine Schiff Base Lanthanide(III) Complexes and their Microbial and Anticancer Activity V. Geethalakshmi, N. Nalini, S.S. Sabithamala, D. Tamilselvi, C.T. Theivarasu Asian Journal of Chemistry, 2022 A novel Schiff base ligand has been synthesized by the condensation reaction of 1-(2-amino ethyl)piprazine with o-vanillin in methanol solution. Using lanthanide(III) metal ions (Ln3+ = La3+, Ce3+, Pr3+, Nd3+, Sm3+ and Gd3+) in methanol, six complexes of piprazine Schiff base were synthesized. All the lanthanide(III) complexes were characterized by IR, UV, NMR, TG-DTA, X-ray diffraction analysis and photoluminence. According to the spectral analysis piprazine act as a bidentate monobasic donor coordinating through the azomethine nitrogen and a phenyl oxygen atom. Antimicrobial studies of the synthesized compounds were evaluated and reported. Anticancer activities were also studied towards the human breast cancer cell line (MCF-7).
Anticancer activity of morpholine Schiff base complexes V. Geethalakshmi, N. Nalini, C. Theivarasu Aip Conference Proceedings, 2020 The condensation of aromatic aldehyde o-vanillin with suitable 4-[2-aminoethyl]morpholine have been formed the 3-methoxy-2-((2-morpholinoethylimino)methyl) phenol ligand(L1). Six lanthanum (III) complexes (LaL1, CeL1, PrL1, NdL1, SmL1, GdL1) and schiff base ligand (L1) were prepared, characterized and screened against in vitro anticancer activity using human breast cancer cell line (MCF7) at different concentration ranges (6.25,12.5, 25, 50 and 100 µg/ml) using a colorimetric MTT assay. The percentage of cell growth is found to be 42-45 %. In anticancer activity, marginal difference has shown for the morpholine schiff base ligand and lanthanum (III) complexes.
Investigation on effects of polyethylene glycols on cadmium sulfide thin films R. Ganesh, V. Manikandan, N. Nalini, S. Prabu Aip Conference Proceedings, 2020 In this present work, we learn about the impact of molecular weights (MWs=150, 600, 4000) of capping agent (polyethylene glycols (PEGs)) on thin film of cadmium sulfide (CdS) layered by chemical bath deposition (CBD). The sample was inspected using X-ray diffraction (XRD), UV–vis absorption, photoluminescence (PL), scanning electron microscope (SEM), surface wettability and DC electrical conductivity studies. XRD pattern revealed that the higher order of PEG orients hexagonal phase structure. A topographical image appears surface modification was enhanced by increasing MW of capping agent. Optical studies confirm that the capping agent has significantly influenced films. Surface wettability analysis exposed that an angle of contact increased in the range of 44-149°. The DC electrical characterization illustrates PEG performs a major role in activation energy and electrical conductivity of thin films.
