READERSHIP: Postgraduate Students, Researchers and Professionals in Physics and Chemistry
I am happy to mention few of the breakthroughs of wounderful science.
A technology that provides connections between and among the sciences that will help students to develop an understanding of the relationships between disciplines. Such integration is emblematic of new ways of thinking about the future and the workplace. Nanotechnology, especially through the convergence of many fields of science and engineering at the nanoscale, will contribute to fulfilling the mission of making students into critical thinkers, capable of participating in intelligent debates about how societies ought to be transformed. Nanoscience has reached within the last decade the status of a leading science with fundamental and applied research prospects in all basic cognitive sciences such as physical, life and earth sciences: from physics and chemistry, biology and medicines, to engineering and agriculture. Nanotechnology is the next industrial revolution and almost all industries will be radically transformed by it in a few years and this technology would directly benefit a common man when it comes to commercial use. It has already established a beachhead in the economy. Fabric industries are using embedded nanoparticles to create stain repellent Khakis. It has played a major rule in development of sensors. If these sensors are fitted into the uniform of soldiers and heaven forbid, if their blood comes in contact with the sensor, it would pass information about the wearer’s condition to the headquarters within nanoseconds. Besides, the sensors we are talking about can even help in monitoring of environment and could provide data on the amount of undesirable elements present in the atmosphere. The application of nanotechnology has enormous potential to greatly influence the world in which we live. From consumer goods, electronics, computers, information and biotechnology, to aerospace defense, energy, environment, and medicine, all sectors of the economy are to be profoundly impacted. Long term developments are likely to occur in convergence with other emerging technologies, such as biotechnology and information technology, where nanotechnology will serve as an enabler of the new product. Nanotechnology can solve many of the world's current problems. For example, water shortage is a serious and growing problem. Most water is used for industry and agriculture; both of these requirements would be greatly reduced by products made by nanotechnology. Infectious disease is a continuing scourge in many parts of the world. Simple products like pipes, filters, and mosquito nets can greatly reduce this problem. Information and communication are valuable, but lacking in many places. Computers and display devices would become stunningly cheap. Electrical power is still not available in many areas. The efficient, cheap building of light, strong structures, electrical equipment, and power storage devices would allow the use of solar thermal power as a primary and abundant energy source. Environmental degradation is a serious problem worldwide. High-tech products can allow people to live with much less environmental impact. Many areas of the world cannot rapidly bootstrap a 20th century manufacturing infrastructure. Finally, nanotechnology will provide cheap and advanced equipment for medical research and health care, making improved medicine widely available. Much social unrest can be traced directly to material poverty, ill health, and ignorance. Nanotechnology can contribute to great reductions in all of these problems, and in the associated human suffering. Above all, we believe that nanotechnology will help solve the most challenging global issues that we face in the areas of energy, health, environment, and global security. Within just five years nanotechnology could be used in nearly half of new products from computer devices to cancer like disease treatments, renewable energy sources, lightweight manufacturing components in cars and aeroplanes, agents for environmental remediation, water filters for removal of viruses, contaminants and salt for the entire world. Such potential strides explain why nanotechnology is viewed as key to future economic growth and why technologically advanced countries are earnestly pursuing its development across the globe. It is estimated that by 2015 this exciting field will need 20 billion workers worldwide. Inclusion of nanotechnology in the science curriculum will foster interdisciplinary explorations of science. Because nanotechnology is an emerging interdisciplinary field, it can be included in physical science, chemistry, physics, biology, environmental sciences and engineering. In an attempt to take part in this fascinating nanoworld and to contribute to its ambitious challenges, there was a dire need of a book on Nanoscience, which could give a clear picture of this wonderful science to our dear students. The book entitled, “Principles of Nanosciences and Nanotechnology” published by M/S Narosa Publishing House, New Delhi is now in the market and hopefully could serve the purpose. People in general and students in particular need to learn more about how science at the nanoscale can benefit us in our everyday lives.
