Fabrication, Characterization, and Evaluation of Eggshells as a Carrier for Sustainable Slow-Release Multi-Nutrient Fertilizers Kalaivani Dayanidhi, Noorjahan Sheik Eusuff ACS Applied Bio Materials, 2021 Development of environment-friendly fertilizers to adhere to the sustainability in agronomic practices and to overcome the limitations posed by the conventional fertilizers has been an important challenge. In this study, a cost-effective biowaste eggshell (ES) material was utilized as a sustainable support for eco-friendly slow-release multi-nutrient fertilizers (SMFs) by simple impregnation of micro- and macronutrients. The synthesized multi-nutrient composite was characterized by various characterization techniques. The leaching tests were conducted using simulated soil solutions and tap water, which showed slow and steady release patterns of the impregnated nutrients. Also, the water holding and water retention capacity of soil were improved upon addition of ES-SMF. Further, the results of pot experiments showed enhanced plant growth of cucumber (Cucumis sativus) and tomato (Solanum lycopersicum) seedlings that proved the efficiency of ES-SMF to serve as an environment-friendly fertilizer in agriculture to attain sustainability.
Facile synthesis of Silver@Eggshell nanocomposite: A heterogeneous catalyst for the removal of heavy metal ions, toxic dyes and microbial contaminants from water Kalaivani Dayanidhi, Porchezhiyan Vadivel, Shobana Jothi, Noorjahan Sheik Eusuff Journal of Environmental Management, 2020 In this work, silver nanoparticles have been synthesized with an average particle size of 35 nm, within 90s, using microwave and Sapindus mukorossi extract as a stabilizing agent. The AgNps were surface immobilized on eggshells (ES) to obtain Ag@ES, which was characterized by UV-Vis, UV-DRS, FT-IR, ICP-OES, TGA-DSC, SEM-EDX, XRD and XPS. Its applicability as an environmental catalyst was evaluated by Cr (VI) adsorption, photocatalytic degradation of methyl orange, eriochrome black-T, methylene blue, rhodamine-B as model dyes and microbial inhibition against Staphylococcus aureus, Escherichia coli and Candida albicans. The results revealed that Ag@ES exhibited maximum adsorption capacity of 93 mg/g for Cr (VI) ion and degradation efficiency of ~90-98% for removing anionic and cationic dyes. Further, it showed a minimum inhibitory concentration of 15.6, 7.8 and 31.2 μg/mL for S. aureus, E. coli and C. albicans respectively. Moreover, the Ag@ES being a heterogeneous catalyst can be regenerated and reused without significant loss in its efficiency.
Synthesis, docking and in vitro evaluation of L-proline derived 1,3-diketones possessing anti-cancer and anti-inflammatory activities V. Porchezhiyan, D. Kalaivani, J. Shobana, S.E. Noorjahan Journal of Molecular Structure, 2020 Unsymmetrical 1,3-diketones with potential anti-cancer as well as anti-inflammatory activities were synthesized via direct coupling reaction between ketones and N-acyl benzotriazoles, based on soft enolisation under mild conditions and characterized by 1H,13C NMR, IR and HRMS. Molecular docking of the synthesized compounds (5a-5j) with the enzymes PTK6 (breast cancer cell), COX-1 and COX-2 (inflammation and pain) revealed 5j to be the potent compound. It was found to inhibit several important mitogen activated protein kinases, preferentially p38β with a binding energy of −11.2 kcal/mol. During in vitro studies for MTT cytotoxicity assay using breast cancer cell line (MDA-MB-231) and HRBC assay for anti-inflammatory studies, the compound 5j exhibited anti-cancer activity with IC50 = 3.4 μM and 94.7% stabilization respectively. Thus the synthesized compounds (5a-5j) with more drug likeliness and high GI values as proved by the Swiss ADME online portal, can be effective in inhibiting breast cancer cells and the associated inflammation.
