Nitride-dilute magnetic semiconductors (NDMS) are materials with magnetic and semiconducting properties, with potential applications in advanced electronic devices. Magnetic properties are introduced by doping with impurities such as Mn, Fe, and Co, which affect the band structure and electronic properties, resulting in unique spin-dependent electronic transport and optical properties. The incorporation of impurities also allows for the control of magnetization and spin properties through tuning of doping concentration and annealing conditions.

Due to their excellent qualities and wide range of uses, magnetic nanoparticles have become a focus of research, particularly in tackling the urgent issues of water and wastewater treatment. Both the ecosystem and human health are seriously endangered by the heavy metals and pollutants that enter water supplies. These contaminants, which come from a variety of industrial processes and human activities and include Hg, Cr, Cd, As and Pb add to a significant environmental problem. Magnetite nanoparticles have emerged as one of the most effective adsorbents for removing these heavy metal particles from water among the techniques used for water purification. They are an attractive option for water filtration due to their inherent physiochemical characteristics, economic effectiveness, and simplicity of recovery in the presence of external magnetic fields. In this seminar, the prospective use of magnetite nano adsorbents in water filtration is evaluated critically. The manufacture of magnetic iron oxide (Fe3O4) nanoparticles is also covered, with emphasis on the co-precipitation, hydrothermal, and sol gel processes. presents a thorough overview of the potential of magnetic iron oxide nanoparticles in addressing serious problems with water contamination. It also offers insights into their use in water treatment, with a focus on the removal of heavy metal ions.

Climate modeling is considered an important tool to enhance our understanding about how the Earth’s climate system works. Nowadays, scientists use computers codes to calculate the mathematical equation of the different climate components and variables interaction such as atmosphere, ocean, temperature, wind, and other climate variables. As the steady expand in the emission of greenhouse gases (GHGs) across the world will continue, which is the cause of global warming, the probability of occurrence of extreme events such as drought, floods, heatwaves, heavy torrents, typhons, and wildfires will increase if no commitment is made to reduce the emissions of these gases. These extreme events have unfavorable impacts on the global economy, agriculture, human health, ecosystems, and infrastructure system. Drought has become an immense problem and still casts a negative shadow on society and the individuals. Therefore, in this presentation, we are going to use modeling to make projection for the changes in drought characteristics under two Representative Concentration Pathways RCP2.6 and RCP8.5 in the near future (2041-2070) and far future (2071-2100).”
