Sustainability through materials: A review of green options in construction
No full textIn light of the growing worldwide consciousness regarding environmental issues and the depletion of resources, attaining sustainability in the construction sector has become a necessity. This study carefully examines how environmentally friendly materials support sustainable building practices, emphasizing three key areas of investigation: the broad spectrum of feasible green materials, the quantitative differences in emissions between green and conventional materials, and the overall effect of these materials on the economy and health. The study employs a robust quantitative approach, leveraging numerical optimization and detailed analyses to explore a wide array of environmental resources, including recycled, renewable, and low-impact options. A comparison between materials is completed, offering refined insights into the environmental benefits of green materials across the entire life cycle-from manufacturing to lifecycle. The primary findings highlight the observable benefits of using these materials and demonstrate how they can drastically lower emissions and environmental effects. It offers verifiable proof of the viability of removing dangerous exposures and promoting healthier indoor environments by utilizing environmentally friendly materials. The graphical information and numerical findings that are provided in this paper form the basis for putting workable and significant strategies into action. The results support the broad use of green materials by providing evidence of their beneficial effects on economic growth, environmental preservation, and human health. The strong quantitative evidence highlights the applicability of these suggestions and offers a convincing case for incorporating sustainable practices in the building industry

No full textExploring the development of natural biopolymer (chitosan)-based proton exchange membranes for fuel cells: A review
No full textFuel cells use proton exchange membranes (PEMs) to transform chemical energy into electricity. PEMs are selective barriers that permeates protons, obstructing gases and other species like electrons. A polymer electrolyte containing both positively and negatively charged ions forms a PEM. Nafion, a perfluorinated sulfonic acid membrane, is the most popular polymer membrane used as PEM. It exhibits good chemical stability, strong mechanical qualities, and high proton conductivity. However, it has several issues, one of which is its propensity to degrade with time, especially at high temperatures and in the presence of pollutants. The other draw backs associated with perfluorinated based membranes are that they are expensive and non-eco-friendly In order to address these issues, researchers are looking into new materials and methods to form a PEM so that the performance and durability are enhanced .Chitosan (biopolymer) based PEMs have demonstrated great potential to be used in fuel cells. They are environmentally friendly and economical. However, the key challenge in using chitosan in fuel cells is their relatively poor ionic conductivity. Researchers have developed various strategies to improve their conductivity, such as doping with conductive materials or incorporating functional groups that enhance charge transfer. Overall, chitosan has shown promise as renewable and sustainable material for use in fuel cells. The review summarizes the current development and evolution of chitosan-based PEMs
