NANOTECHNOLOGY

August 28, 2009


Nanotechnology is one of the most fascinating “new” technologies that has surfaced in recent years.  The possibilities for growth and usefulness to mankind are evolving at an extremely rapid rate.  The “science” has been called a disruptive technology because it has the possibility of being a “game changer” for so much of what we call common-place in today’s world of fabrication and manufacturing.  The technology allows for completely new methods of producing a product.

The definition of nanotechnology is “the study and control of matter on an atomic and molecular scale”.  The purpose is to assemble every atom, locating them in their proper places, to make ANY structure behave in a fashion consistent with the laws of nature.  When this becomes possible on a large scale, the cost of assembly and fabrication will essentially be equivalent to the cost of the raw materials used for the process.  A remarkable possibly for providing products with minimal cost.

OK, what is a nanometer?  A nanometer is on billionth of a meter.  A meter is 39.37 inches or to put this into perspective, if a marble represents a nanometer, then the diameter of the earth would represent a meter.  Here are several ways to look at this and put a nm into scale:

  • The diameter of ragweed pollen measures approximately 20,000 nm
  • One red blood cell measures approximately 2,500 nm
  • The width of a human hair measures about 100,000 nm
  • A germ cell is approximately 1,000 nm
  • A water molecule is less than 1 nm
  • Shaquille O’Neal is 2,160,000,000 nms tall

 

Already, manufacturing companies are providing products for the following industry categories:

  • Medicine
  • Electronics
  • Space
  • Food and food services
  • Fuel cells
  • Solar cells
  • Batteries
  • Fuels
  • Air quality
  • Chemical sensors
  • Sporting goods
  • Fabrics

 

Items such as flash memory cards, floor cleaners, degreasers, carbon fibers, golf shafts, epoxy coatings, air purifiers, sun care products, electronic processors and antibacterial medicines and ceramics are being produced by incorporating processes using nanotechnology.  One of the greatest possibilities for nanotechnology is treating the most aggressive diseases, such as cancer.   This process would involve the delivery of drugs and medicines to cancer cells otherwise unreachable using current techniques.  This process uses “Q-bots” as the delivery tool, providing chemotherapy where it’s needed and can do the most good.

 

One other area with great possibilities is material science.  Nanotubes and Bucky Balls can provide a remarkable increase in the structural strength of carbon fibers and composite fibers.  Infusion of these structures into steels and polymers can greatly improve the yield strength, Young’s Modulus, shear strength, rupture strength etc of materials formulated for purposes requiring greater “allowable”.

 

In short, nanotechnology is in its infancy with limitless possibilities.

    Hello there,

    Many thanks for taking a look at my web site. I really hope you enjoy the blog. Most of my work is somewhat technical; sometimes commentary but mostly technical. I am very interested in engineering education in the United States as compared to the rest of the world. Hope you come back.

    Take care

      Hello there,

      I am certainly happy you have taken a look at my site. I don’t write as often as I would like due to my work schedule. Oddly enough, I am a technical writer, among other things and find writing somewhat agony–although I do love to work.

      Take care.

      Hello Alexa,
      I hope you are having a great day and looking forward to a great weekend. Just thought I would drop you a note. I’m still getting used to all of the features of WordPress so pardon the delays. Take care.
