A new wave of technological revolution is created by the change of nanotechnology, which is predicted to have a great impact in the future. By definition, nanoscience is the development of chemical and biological nanostructures. In my opinion, nanoscience is kind of a fundamental thesis, which could be based on a mathematical model to explore the small world in the size range from 1 to 100 nm and to discover new knowledge about how this world works. After discovering and understanding its characteristics, nano-engineers can apply those difficult or abstract theses to the real world. I wondered what is going to happen in nanotechnology, so I took this course. I know that both nanoscience and engineering are classified under the term nanotechnology. The basic understanding and engineering advances in nanoscience and nanotechnology have been certainly integrated into a wide variety of research and development work in the laboratory. Nanoscience and engineering are going to develop into real products for different purposes. Therefore, the connection between nano-science and engineering is a path to make the evolution of imaginative ideas come true.
This series of new technology involves manipulating matter on a small scale and is an important ability today. This capability enables the invention or design of new materials, new equipment, and novel applications. The basic understanding of nanoscience and advances in nanoengineering has been integrated into a wide variety of research and development work in the laboratory. These areas of study are also going to help develop real products for many other purposes. The ultimate goal is to learn how to organize nanostructures into the larger, more complex functional architecture called integrated nanotechnology.
In this course, I learned that nanoscience is not only based on different theses but is also widely developed in the real world. I think that nanotechnology will lead a new revolution in years to come. For example, car manufacturers have used nanotechnology in automobile design. By changing the structure of the material, nanoscience can improve the performance of products in the future. In this case, nano-engineering is mainly responsible for the performance-to-cost ratio, such as a lightweight, low cost and stronger structure. When the car gets lighter, the cost of fuel will decrease. It will lead the next generation to a better automotive field. Moreover, after using a new metal to design a car, the material could be used to develop a stronger and longer lasting product. Therefore, nanoengineering is an important field in today’s modern world.
Since the properties of matter can change with scale, finding the perfect size for an application is very important. In particular, when the size of a material is close to the nanoscale, unexpected properties might lead to new function. As a result, studies involving nanomaterial would help make more advanced products. The application of nanoscience, nanoengineering and nanotechnology develops into commercial products. I thought that changing the size of materials would cause some problems in the final products because each material has different limitations, but the truth is that nanotechnology has overcome most of its difficult situations. After taking this course I know that nanoscience can enable a large increase in the applications of nanotechnology to commercial products.
I learned that nanotechnology is a new concept, which is a comprehensive subject of nanoscience and engineering. I had great opportunities to read different texts in several fields; above all, the reading about electron microscopes was the one that drew my attention. The relationship between microscope techniques and nano-material will be a linear change in the years to come.
By using microscopes, I can observe those tiny phenomena to understand a different structure of a substance. Since I am a hands-on student, I want to explore the microscopic world of nanoscale objects and I like to work on the equipment to get a demonstration. Also, after reading these materials, I learned how to choose the correct microscope for different situations. For instance, to analyze the defect on a sample’s surface, in which SEM is needed, and to observe the structure of matter, in which TEM is needed. This knowledge will help me in the analysis process of my studies.
I think that nanotechnology will continue to be popular in the future because nanoscience and engineering have already put more convenient products into the market. For example, some medical products are using nanotechnology to get benefits. The tools of medicine are getting cheaper and the quality is getting higher.
I believe that nanotechnology in biology will make great changes in the next generation.
This has been a comprehensive course, including the connections between the structure and properties of materials, the processing and production aspects, the properties of source, and the performance of products. Therefore, this course presents a larger concept of nano-material. I like the article about the revolution of nano-science and engineering, which was necessary for the full realization of the potential of nanotechnology. It presented the big picture of nanoscience and engineering, and I also learned about applications in nanotechnology. Although some people in the nano-science world might doubt that nanoproducts are dangerous, it is necessary to resolve the present uncertainties in their safety. Many people believe that there needs to be a re-emergence of science and education, along with a change in the political environment, in order to have a sustainable development of nano-science and engineering in years to come. The continued development of nanotechnology should be desired because it creates a lot of modern convenience, which can lead society to more advanced levels.
