From solar paint to instantly rechargeable 18650 lithium ion battery cell, nanotechnology is the key

　　Have you ever thought about it, maybe embedded solar cell paint can turn your house into a big solar panel; cancer-fighting quantum dots can defeat cancer cells one by one without damaging healthy tissue; mobile phone 18650 lithium ion battery cell don’t need a few hours and can be charged in just a few seconds.

　　In the field of nanotechnology engineering, raw materials are processed or devices are developed that have at least one dimension smaller than 100nm, which is approximately one thousandth the width of an average human hair. Most current electronic technologies already use nanotechnology, and these new applications take its role to the extreme. By processing at the atomic and molecular levels (also known as the quantum realm), the specific mechanical, thermal and contact-responsive properties of materials can be altered.

　　Jo-Won Lee, chief professor of the Department of Integrated Nanoscience at Hanyang University in Seoul, South Korea, and IEEE member, pointed out: For these nanotechnologies, the challenge of becoming mainstream applications comes from how we can economically and efficiently apply them in practical applications. He said that traditional manufacturing usually does not reach the nanometer level, but an improved method has been born, called self-assembly. In essence, nanodevices build themselves, which is consistent with the construction of molecules to form larger systems. The approach is very similar.

　　IEEE and its members play an important role in the practical environmental applications of nanotechnology. For example, the IEEE Nanotechnology Committee is promoting and coordinating efforts in this area, including nanotechnology theory, design, and development, and its applications in science, engineering, and industry.
