Benefits and Application of Nanotechnology in Environmental Science: an Overview

Biointerface Research in Applied Chemistry, 2020

As a result of world population growth, consumption of energy and materials is increasing, leading to environmental consequences. Some of these consequences include increased production of solid waste, increased air pollution caused by vehicles and industrial plants, contamination of surface and groundwater. Nanotechnology has the potential of improving the environment through direct application of nanomaterials for detecting, preventing, and removing pollutants and indirect application of them by using better industrial design process and production of products compatible with the environment. Nanoparticles show higher reactivity due to their small size and high surface. While this characteristic has various benefits and applications, it may have risks for the safety of employees and the environment, such as stay suspended in the air for a long time, possibility of accumulation in the environment, easy absorption, and damage to various organs of the body. This review has investigat...

Environmental application of nanotechnology

Annual Review of …, 2008

Nanotechnology is an emerging field that covers a wide range of technologies which are presently under development in nanoscale. It plays a major role in the development of innovative methods to produce new products, to substitute existing production equipment and to reformulate new materials and chemicals with improved performance resulting in less consumption of energy and materials and reduced harm to the environment as well as environmental remediation. Although, reduced consumption of energy and materials benefits the environment, nanotechnology will give possibilities to remediate problems associated with the existing processes in a more sustainable way. Environmental applications of nanotechnology address the development of solutions to the existing environmental problems, preventive measures for future problems resulting from the interactions of energy and materials with the environment, and any possible risks that may be posed by nanotechnology itself.

Nanotechnology is a field where scientific knowledge and ideas emanating from the sub-atomic, atomic and molecular levels are applied in the manufacture of new and smart materials. Nanotechnology makes use of the novel properties exhibited by materials in the nanoscale. Nanocrystalline materials have microscopic grain sizes of up to 100 nm with remarkably distinct optical, electrical, chemical, mechanical properties different from those of bulk materials. Nanoparticles can be used to develop materials with unique properties since the number of atoms on the surface of a particle in the nanoscale is comparable to that inside the particle. Hence in order to meet the advanced technological demands in the areas such as electronics, catalysis, ceramics, magnetic data storage, structural components etc., it is important to make use of materials in the nanometer scale. Nanotechnology is a rapidly growing field of science which encompasses researchers and scientists from the areas of biology, chemistry, engineering, materials science and physics. This technology provides the basis for research and manufacture of materials in the 21st century. In addition, this interdisciplinary technology will provide a strong platform for the growth of pharmaceutical industry, medical diagnosis, materials industry and the overall economy of the country which will eventually enhance creation of job opportunities, food security, good health and affordable housing in line with the government's "big four" agenda. It promises improved efficiency in ICT equipment used in computing, data storage (chips) and communications (fibre optics). It can be used to develop renewable energy sources such as solar cells and panels. It can also be utilized to synthesize filters that can be used to get rid of pollutants; contaminants, harmful salts and viruses in water and sewerage systems and for the diagnosis and treatment of diseases including cancer and to restore damaged human organs or tissues using engineered tissue.

Fundamentals of Nanotechnology for Environmental Engineering

As a means of reducing pollution and hazardous waste, nanotechnological products, techniques, and applications are expected to have a significant impact on environmental engineering. Because of this, the use of nanomaterials has the potential to have both immediate and long-term positive effects on the environment and human health. However, nanotechnology is now playing a very small role in environmental protection, whether in research or in real applications. When it comes to environmental engineering, nanotechnology has little practical use. In response to rising costs of raw materials and energy, there has been a rush of goods on the market that claim to provide environmental and climatic advantages. Basic fundamentals of nanotechnology and fundamental environmental engineering are discussed in this chapter in detail.

International Journal of Management, Technology, and Social Sciences (IJMTS), 2021

Nanotechnology is considered as a tool for solving problems and providing comfort in the livelihood of human beings, also possess challenges and treats if not used carefully. nanotechnology if used properly can support to realize the 17 Sustainable Development Goals (SDG) to be realized by 2030. Nanotechnology, being multidisciplinary frontier technology useful for innovative solutions in primary, secondary, tertiary, and quaternary industry sectors has shown slow progress due to its potential risks due to predicted nanotoxicity. To counter this but to use nanotechnology solutions in societal progress, green and eco-friendly nanotechnology solutions play a major role in realizing sustainable development goals and eliminates the threat of the technification of development processes. This paper discusses the concept, current research outcome, and the industrial prospects of achieving global SDG and much more using green and eco-friendly nanotechnology in 21st century.

Nanotechnology for sustainable development: retrospective and outlook

Journal of Nanoparticle Research, 2013

The world is facing great challenges in meeting rising demands for basic commodities (e.g., food, water and energy), finished goods (e.g., cell phones, cars and airplanes) and services (e.g., shelter, healthcare and employment) while reducing and minimizing the impact of human activities on Earth's global environment and climate. Nanotechnology has emerged as a versatile platform that could provide efficient, cost-effective and environmentally acceptable solutions to the global sustainability challenges facing society. This special issue of the Journal of Nanoparticle Research is devoted to the utilization of nanotechnology to improve or achieve sustainable development. We highlight recent advances and discuss opportunities of utilizing nanotechnology to address global challenges in (1) water purification, (2) clean energy technologies, (3) greenhouse gases management, (4) materials supply and utilization, and (5) green manufacturing and chemistry. In addition to the technical challenges listed above, we also discuss societal perspectives and provide an outlook of the role of nanotechnology in the convergence of knowledge, technology and society for achieving sustainable development.
