Nano clays improve the physical characteristics

Nanotechnology was first recognized on broad scale after Nobel Laureate, Richard Feynman, presented his classic talk titled, Theres Plenty of Room at the Bottom to the American Physical Society in when discussing the changing nature of the field of physics. It includes knowledge from biology, chemistry, physics and engineering, nanotechnology is the manipulation and assembly of material with atomic precision.

Nanotechnology Basic research on manmade structures that Have at least one dimension of less than nanometers Are designed through process that exhibits fundamental control over the physical and chemical attributes of the structures and Can be combined to form larger structures. nanometer is 180,000 the diameter of human hair or approximately ten hydrogen atoms wide! But nanotechnology is not just involved with small things. The term nanotechnology actually means nanoscience nanotechnology is used because it is the more common expression. The intersectionof materials and biosciences represents new class of chemicals and manmade pharmaceuticals that improveour lives.

By developing materials at the molecular level, scientists can create new forms of matter that are stronger and more elastic, refract light differently, have different electrical characteristics, and even respond to their environment. Nanotechnology Basic research on manmade structures that Have at least one dimension of less than nanometers Are designed through process that exhibits fundamental control over the physical and chemical attributes of the structures and Can be combined to form larger structures. Life scientists are already using nanotechnology to advance healthcare.

And, finally, the intersection of all three is nanotechnology research into selfassembling,smart materials with myriad applications and far greater performance potential than existing materialsand devices. Unusual forms of matter called quantum dots help diagnose disease and discover new drugs. This diagram of three intersecting circles portrays the overlap of three fields of research biosciences, electronics and materials. In the future, nanotechnology will provide us with new solutions to face the worlds greatest challenges.

But remember, nanotechnology can involve other scientific arenas, and it is not limitedto those used in this example. Different electrical and physical interactions come into play at the nanoscale, so scientists need an understanding of many different disciplines when working in nanotechnology. The scope of sciences important in nanotechnology is depicted in the logo used by the Texas nanotechnology research initiative. Fighting disease, saving lives, feeding the hungry, cleaning up our environment and exploring our solar system will seem less daunting as nanotechnology develops. Nano means onebillionth, so nanotechnology deals with materials measured in billionth of meter.
