In this work, Chromium substituted nickel ferrites with general composition NiCr_xFe_2-xO₄&nbsp;(x= 0, 0.25, 0.5, 0.75, 1) were prepared using sol gel auto combustion method. The structural characterization of the samples was carried out using X-ray diffraction (XRD) which confirmed the presence of single-phasic spinel structure and energy dispersive X-ray (EDX) spectroscopy analysis confirmed the presence of all ions as per the stoichiometric ratios.&nbsp; Surface morphology of the samples has been investigated using Field Emission Scanning Electron Microscope (FESEM). The bandgap of the prepared samples was measured using UV-Visible-Diffuse Reflectance Spectroscopy (UV-Vis-DRS Spectroscopy). The antibacterial properties of the prepared compounds were tested against gram-positive and gram-negative bacterium and found that antibacterial property decreased with increase in concentration of Chromium for gram-positive bacteria.</p> V N Archana, Jeevan Johns, T R Anilkumar, Shilpa J Chethalen, Anju Ganesh Copyright (c) 2025 V N Archana, Jeevan Johns, T R Anilkumar, Shilpa J Chethalen, Anju Ganesh https://creativecommons.org/licenses/by/4.0 http://jasetm.fisat.ac.in/index.php/jasetm/article/view/39 Tue, 14 Jan 2025 00:00:00 +0000 http://jasetm.fisat.ac.in/index.php/jasetm/article/view/40 <p>This study investigates the impact of temperature variations on the efficiency of two identical 50-watt monocrystalline solar panels, one equipped with active cooling and the other without any cooling mechanism. Conducted in a controlled environment simulating real-world temperature conditions, the experiment compares the panels' power output and overall performance. The panels are exposed to diverse thermal conditions to isolate the effect of temperature on efficiency. Detailed data on electrical output, temperature, and other parameters are systematically collected and analyzed using MINITAB 17 software. The analysis reveals key correlations and trends, providing predictive models that demonstrate how active cooling enhances panel efficiency under varying temperature conditions. These findings offer valuable insights into optimizing solar panel performance, particularly in regions with high thermal fluctuations.</p> Roshan Ajit , C R Rejeesh Copyright (c) 2025 Roshan Ajit , C R Rejeesh https://creativecommons.org/licenses/by/4.0 http://jasetm.fisat.ac.in/index.php/jasetm/article/view/40 Wed, 14 May 2025 00:00:00 +0000
