Wind energy is converted into electricity using wind generators or wind turbines installed in wind farms. It is linked to the kinetic energy of the wind, which is produced when air moves. The energy can be used to create mechanical motion, such as the rotation of the rotors of a wind turbine. To harness wind energy, wind turbines or generators are installed to convert the kinetic energy of the wind into electricity. A...

Biopolymer-based packaging materials are increasingly favored for their eco-friendly and biodegradable properties. Among the promising biopolymer materials, agar-based biodegradable films stand out since they are made from water and plasticizers like glycerol. However, they often suffer from reduced mechanical strength and higher moisture sensitivity compared to synthetic alternatives. To address these issues, this study explores the incorporation of silver nanoparticles (AgNPs) into agar-based films using Aloe ve...

Well-aerated soils are essential for methane (CH4) uptake from the atmosphere, acting as significant sinks for this greenhouse gas, which has a global warming potential 25 times greater than that of carbon dioxide (CO2). These soils contain methanotrophic bacteria, which oxidize CH4 and thereby reduce atmospheric methane concentrations. The potential of soils to assimilate CH4 depends on factors such as soil type and moisture regime. This study investigates the ability of clay soil Cambic Calcisol to assimilate CH...
