Recent Patents on Nanotechnology - Volume 15, Issue 3, 2021

Background: Environmental pollution has been a recognized problem for human health and the ecosystem. Remediation is usually costly and time-consuming, so researchers' attention has been drowning to develop and use new materials. This review aims to summarize the recent development of carbon-based materials used for environmental management. Methods: We conducted a detailed analysis of available li Read More

Background: Globally, around 150 million people are still supplied with arsenic contaminated drinking water. The groundwaters effected often contain problematic concentrations of natural organic matter (NOM), which plays an important role in releasing As into the aquifer. Thus, this review explores the recent literature relating to the application of various nanomaterials to solve these drinking water supply problems Read More

Background: Over the last two decades, thousands of scientific papers and many patents have been written relating to applications of ionic liquids, a family of compounds that garnered such huge interest due to their reputation as "green chemicals". This work reviews the recent literature to investigate the progress ionic liquids have made in their transition from academia to full-scale application in a variety of industries. Meth Read More

Background: The application of zero-valent iron nanoparticles (nZVI) to remediate soil and groundwater has gained increased attention within the last decade, primarily due to their high reactivity, cost-effectiveness and potential to treat a broad range of contaminants (e.g., chlorinated organic solvents, inorganic anions, or metals). Objective: In this paper, the state of the art of applicability of nanomaterials, especially the most f Read More

Background: Reuse of waste materials present in the technosphere, such as the metal mining tailings is becoming a more economical and energy-efficient method for obtaining the raw materials than the classical mining. Number of patents are presenting methods for tailings recycling, often in construction industry and metallurgy. At the same time, world market for metallic nanomaterials is rapidly increasing with numerous ne Read More

Background: In past years, nanomaterials have been actively studied and developed and successfully used in many fields. Due to water scarcity, the application of nanomaterials in water and wastewater treatment has drawn significant attention. Due to their superior features, they represent functional materials with great potential for pollution removal and environmental applications. Objective: This literature review aims to s Read More
