Nanotechnology - Poisontoxicity A selection of articles related to Nanotechnology - Poisontoxicity: Nanotechnology - Goo. An often cited worst-case for everyone scenario is "grey goo", a hypothetical substance into which the surface objects of the earth might be transformed by self-replicating nanobots running amok, a process which has been termed global ecophagy. Defenders point out that smaller objects are more susceptible to damage from radiation and heat (due to greater surface area-to-volume ratios): nanomachines would quickly fail when exposed to harsh climates Nanotechnology - Definition. Nanotechnology is any technology which exploits phenomena and structures that can only occur at the nanometer scale, which is the scale of single atoms and small molecules. The United States' National Nanotechnology Initiative website defines it as follows: "Nanotechnology is the understanding and control of matter at dimensions of roughly 1 to 100 nanometers, where unique phenomena enable novel applications." Such phenomena include quantum confinement--which can result in different e .. See this and more articles and videos below.

Nanotechnology - Goo. An often cited worst-case for everyone scenario is "grey goo", a hypothetical substance into which the surface objects of the earth might be transformed by self-replicating nanobots running amok, a process which has been termed global ecophagy. Defenders point out that smaller objects are more susceptible to damage from radiation and heat (due to greater surface area-to-volume ratios): nanomachines would quickly fail when exposed to harsh climates. This argument depends on the speed of w ...

* Encyclopedia II - Nanotechnology - Advanced nanotechnology Advanced nanotechnology, sometimes called molecular manufacturing, is a term given to the concept of engineered nanosystems (nanoscale machines) operating on the molecular scale. By the countless examples found in biology it is currently known that billions of years of evolutionary feedback can produce sophisticated, stochastically optimized biological machines, and it is hoped that developments in nanotechnology will make possible their construction by some shorter means, perhaps using biomimetic principles. However, K Eric Drexler and othe ...

* Encyclopedia II - Nanotechnology - New materials devices technologies

As manufacturing technology becomes more sophisticated it naturally enters the realm of what is arbitrarily labeled nanotechnology. Nanotechnology is based on the fact that the properties of materials become markedly different when their size approaches that of a few hundreds or tens of atoms. Nanoparticles (nanometer sized clusters of atoms), for example, have proved useful in catalysis. A material that is catalytically inactive on the macroscale can behave as a very efficient catalyst when in the form of nanoparticles. For this and other r ...
