The inhalation of airborne particles can endanger the health of any human being. Natural fiber and natural fiber reinforced with natural matrix material are employed in this work to create an indoor air purifier. Various natural fiber and natural composite combinations are used to purify the interior environment by eliminating particulate matter of various sizes and volatile organic chemicals. An air purifier is created using four distinct natural fibers, including hemp, jute, silk cocoon, and coir fibers, as well as neem and alovera gel as natural filler materials. An air quality-monitoring instrument is used to validate the performance of the designed natural fiber/natural plant-based filler material-equipped air purifier. Particulate matter of various sizes and volatile organic compounds in the indoor environment are detected at various time intervals. The efficacy of the air purifier is afterwards determined in human lungs of various ages utilizing health impact simulation studies. The current product is utilized to effectively purify indoor air by eliminating particulates and volatile organic chemicals.

This paper focused on investigating the dynamic behavior of hybrid composites involving natural fibres. The objective of this study is to investigate and evaluate the effectiveness of recently used hybrid composite materials. The main materials utilised are glass fibre reinforced plastic. Plastic is applied to the surface of fibre-reinforced epoxy composites. Natural fibres are used in the other material, polyester-based hybrid composites. The breakage pressure of the double shear test in the first composition has been improved from 1.10 to 1.38 kN. The hardness rating improved from 76.15 to 87.99. The interlamination experimental findings improved from 7.96 to 8.52 kN. The results showed that a hybrid with a 50:50 comparable strand ratio of glass and sisal outscored a hybrid with a small fraction of sisal fibre. The second composite describes the effects of natural filler loading at 5%, 10%, and 15% on the mechanical behaviour of a polyester-based hybrid. Materials created in a reputable environment for automotive and marine applications. Both hybrid nanocomposite preparation methods are tested and the findings are validated. The electrical and mechanical characteristics of the materials are also validated and demonstrated to be superior to other current composites.

Background: The Internet of Things (IoT) is a key factor in the transformation of conventional factories into smart ones, enhancing manufacturing through hardware, software, and sensors. IoT makes it possible to foresee when machines can malfunction, which decreases downtime and increases equipment longevity. By tracking shipments and providing real-time updates on deliveries, suppliers also profit from IoT, which improves the efficiency of supply chains. IoT is an effective tool for managing inventory in smart factories, reducing costs, and giving customers real-time stock updates. Objective: This research examines how Industry 4.0's smart factories utilize IoT for Supply Chain optimization, asset tracking, quality control, predictive maintenance, inventory management, and production monitoring. The aim is to develop innovative strategies for improving production quality and efficiency while providing a comprehensive survey of recent studies and patented advancements in IoT integration. Methods: This paper is rooted in a methodical examination of literature addressing the convergence of Industry 4.0 and IoT in SCM. The authors performed a rigorous search across academic databases and pertinent journals to pinpoint the most pertinent articles and research papers. Following this, an analysis and synthesis of these studies were conducted to identify common themes and findings, which will be safeguarded through patent protection. Result: The literature review highlights the transformative effect of IoT on traditional manufacturing facilities, transitioning them into smart factories. This transition, in turn, enhances the efficiency of supply chains, reduces operational costs, and bolsters customer satisfaction. IoT integration in SCM provides empowerment of businesses by means of real-time data on inventory, manufacturing, and logistics. Conclusion: The study highlights the significance of IoT integration in SCM, identifying trends, challenges, and opportunities. It recommends businesses incorporate IoT into their strategies, leveraging patented technologies to optimize operations and gain a competitive edge.
