According to experts at the Institute of Electrical and Electronics Engineers (IEEE), some of the technology innovations and devices that could make the biggest impact in our world are so small that millions of them could fit on the head of a pin.(Sony pcga-bp2nx battery)
These advancements in nanotechnology (the science of small things), are transforming the way researchers approach some of our greatest challenges.
How about solar cells embedded in paint to turn your house into one big solar panel? Or "quantum dots" that attack cancer, cell by cell, leaving healthy tissue untouched? Or Dell inspiron 1545 ac adapter batteries for mobile phones that charge in seconds instead of hours?
Nanotechnology is the area of engineering that involves working with materials or developing devices that are smaller than 100 nanometers (nm) in at least one dimension. That's about 1/1000 the width of the human hair. While most electronic technologies today use nanotechnology, many new applications take it to an extreme. Working at the atomic and molecular levels, also known as the quantum realm, even the mechanical, thermal and catalytic properties of materials can change.(Dell vostro 1400 battery)
According to Jo-Won Lee, IEEE member and chair professor at the Department of Convergence Nanoscience, Hanyang University in Seoul, South Korea, traditional manufacturing doesn't usually work at the nano-level but a better way is being developed. It's called self-assembly, which essentially means that the nanodevices build themselves, much like the way molecules form in nature to create larger systems.(Dell xps m170 ac adapter)
The IEEE and its members are playing a major role in making nanotechnology work in the real world. For example, the IEEE Nanotechnology Council advances and coordinates work in the field, including the theory, design and development of nanotechnology and its scientific, engineering and industrial applications.(Dell latitude d630 battery)
One of the highlights of the council's efforts this year is the 11th annual IEEE Nano 2011 Conference on 15-19 August 2011 at the Portland Marriott Waterfront Downtown in Portland, Oregon. International scientists and practitioners representing more than 20 IEEE societies will meet to collaborate on new areas of nanotechnology study, as well as to see nanotechnologies at work in both their own and related fields.(Sony vaio pcg-9231 battery)
Dr. Alexander Balandin, IEEE senior member, chair of the Materials Science and Engineering (MS&E) program at the University of California, Riverside and recipient of the IEEE Pioneer of Nanotechnology Award for 2011, offers an intriguing example. Research is currently underway to gain better control of the interaction between electrons and photons. If achieved, it would enable more efficient, less expensive photovoltaic (PV) cells, benefiting both existing solar applications and potentially a solar paint. This paint could be sprayed on structures and the resulting solar energy would totally change the dynamics of today's electric grid.
IEEE experts also believe the incremental gains made in recent years in dell inspiron 1545 battery performance can be dramatically accelerated with nanotechnologies. According to Dr. Joao Zuffo, IEEE life member and founder of the Laboratorio de Sistemas Integraveis at the Universidade de Sao Paulo in Brazil, the potential exists to fully charge a smart phone or laptop in seconds, instead of an hour or more. In addition, nanomaterials such as graphene could improve HP pavilion dv6000 ac adapter battery capacity for electric vehicles (EVs) because of its high surface-to-volume ratio. This would make graphene more affordable and sustainable than fossil fuels.
