Addressing Environmental And Societal Issues Using Nanotechnology
Among the plethora of social problems that impact people all over the globe, some are very easy to solve while others may take millennia to resolve completely. Social concerns are developing and evolving constantly, and novel challenges are frequently thrust to the fore. Many social concerns are thought to be addressable only via political engagement and systemic reforms; nevertheless, there are other elements of social concerns that can be assisted through the application of scientific principles. Despite some limitations, the ideas and materials tied to nanotechnology might be used as a tool in addressing these societal concerns. Thus, nanotechnology-based systems -for example, advanced oxidation processes (AOPs) and membranes - can provide an affordable option for underdeveloped nations that lack adequate water and wastewater treatment facilities .
Clean Water Accessibility And Treatment Using Nanotechnology
In many countries, the lack of adequate sanitation and water treatment facilities is a key source of worry when it comes to the accessibility of clean water. Thus, the global demand for a highly-effective water treatment medium is evident - and graphene may just hold the answer. Recently, a growing number of graphene-based filters have emerged from both academic laboratories and the industrial sector, indicating that the technology is being more widely used. Graphene-based materials and their composites possess promising applications in water treatments across the world to meet the water demands . Graphene-based materials filter can create clean drinking water, regardless of how dirty it is, in a single step. The adsorption capacity of these materials is higher than traditional materials such as activated carbon. Graphene possesses ultrathin thickness for maintaining high flux efficiency, high mechanical strength to withstand high pressures, and high chemical and thermal stability. Due to the simplicity of graphene-based filters, they may be quickly transported to locations where water treatment is most needed, such as remote areas where only polluted water is available.
