Walking into the future: Energy Harvesting from Foot Fall
Abstract: The rapid depletion of non-renewable energy resources and the rising demand for sustainable alternatives have led to the exploration of innovative energy harvesting technologies. One such approach is harnessing the untapped mechanical energy produced by human footfalls in crowded public areas. This project presents a novel method of electricity generation using a flywheel-based mechanical system that captures and converts footstep energy into electrical energy. The system is designed to be …

Fabrication and Characterization of PLA-CSP Composites via FDM for Biodegradable Food Packaging
Abstract: In light of the growing need for environmentally friendly alternatives to conventional plastic packaging, this study presents the design of a food-grade, biocompatible packaging material composed of Polylactic Acid (PLA) and packed with coconut shell powder (CSP). One of the most well-known thermoplastic polymers, PLA is produced from renewable resources like sugarcane or maize starch. Its nontoxicity, biodegradability, and adherence to food safety standards and regulations provide energy. Unfortunately, PLA's …

A comprehensive review on Sustainable Pathways to Synthesize 2, 5-Furandicarboxylic Acid (FDCA) from 5-Hydroxymethylfurfural (HMF) via Oxidative Processes
Abstract: The increasing global concern over the environmental impact of traditional plastics derived from petroleum and natural gas has spurred a search for more sustainable alternatives. Bioplastics, which are derived from renewable sources and may be biodegradable, have garnered significant interest as eco-friendly materials. Among the promising building blocks for bioplastics, 2,5-Furandicarboxylic Acid (FDCA) has emerged due to its potential to enhance polymer properties. One key precursor for bioplastics, 5-Hydroxymethylfurfural (5-HMF), …

Synthesis and Characterization of Sustainable, Low-Cost, Biomass-Derived Carbon Films from Hevea Brasiliensis (Rubber) Wood for Environmentally Friendly Gas Sensors with Enhanced Selectivity and Sensitivity to Polar Vapors and Hazardous Gases
Abstract: Hevea brasiliensis (rubber) wood sawdust was utilized to fabricate carbon gas sensors for detecting 1000 ppm of ethanol, methanol, acetone, carbon dioxide, and ammonia gases. The carbon particles were prepared by phosphoric acid impregnation followed by thermal activation and then fabricated into films on conductive and non-conductive substrates using the doctor blade method. X-ray diffraction (XRD) analysis revealed distinct graphitic features with peaks at the (002) and (100) planes, indicating …

Dispersion Analysis of TE Modes in 1D Magnetized Ferrite Photonic Crystals for Tunable and Switchable Band Gap Filtering Device Applications under Transverse Magnetization Configuration
Abstract: The article comprehensively explores the dispersion characteristics exhibited by TE modes within one-dimensional magnetized ferrite photonic crystals, particularly under the influence of transverse magnetization. We employed the rigorous transfer matrix method, a powerful tool for theoretical investigation, calculation, and behavior analysis of such intricate systems. Our research delves into the structural parameters that govern the behavior of these ferrite photonic crystals, explicitly focusing on the incident parallel wave vector (β) …

Microwave-Assisted Synthesis of Li₃Ba₂Gd₃(MoO₄)₈ Phosphors Doped with Pr³⁺ and Sm³⁺ for High-Performance Red Emission in LED Applications
Abstract: In this study, we report the successful synthesis of Li₃Ba₂Gd₃(MoO₄)₈ (RE³⁺ = Pr³⁺, Sm³⁺) phosphors using a novel, microwave-assisted solid-state reaction method at ambient temperature. The synthesis involved the use of analytical grade reagents including Lithium Nitrate (LiNO₃), Barium Nitrate, Gadolinium Nitrate (Gd(NO₃)₃·6H₂O), Ammonium Molybdate ((NH₄)₆Mo₇O₂₄·24H₂O), and high-purity oxides of Praseodymium (Pr₂O₃) and Samarium (Sm₂O₃). The reagents were mixed in stoichiometric ratios, ground thoroughly in a pestle and mortar, and …
