The relation of nanotechnology ,Maya and Nanoart

It uses nanotechnology for the centuries. A good example is the Maya Blue, a blue pigment is first in the ninth century by the Maya and Aztecs. It is a hybrid compound consisting of particles of organic material (indigo, derived from the leaves of the indigo) and inorganic (a silicate layer, which in some clays). The result is a substance very resistant to the passage of time, weather, and even most chemical solvents and acids. The organic dyes are generally degraded very low resistance and easy, but in this case, their Dell Inspiron Mini 1012 Battery association with an inorganic material is a "protection".

The cut was made to the Lycurgus C in the fourth century in Rome. At daybreak the mythological scene is represented in green and opaque. If it glows red from the inside out and becomes translucent. Responsible for these color changes, nanoparticles of gold and silver Dell Studio 17 Battery  will be produced.

Without knowing it, nanotechnology

Another interesting example of the use of nanotechnology in old age is the color of the windows of cathedrals. The colors were obtained by heating and cooling the glass in a controlled manner. What is unknown to the Middle Ages through this process that is achieved, the size of the crystals on the nanometer scale and thus to change Asus UX50 Battery its color.

Even during the Middle Ages, the famous ceramics of Manises (Valencia), a formula from the Andalusian Muslims who succeeded importing the highly praised the metallic luster of its parts. This recetaincluía nanoparticles of silver and copper.

In Damascus steel forged from the Middle Ages, the most famous swords, cut hard, hard, and yet in a position with his razor, hair loss. Recent studies have the presence of carbon nanotubes in their composition, prepared by the methods used reveals forging. These nanotubes Asus UX50V Battery are recently discovered properties of nanoparticles to exceptional hardness. The difference in this old nanotechnology today is that we now have the tools to see what happens on the nanometer scale and the forecasting rules, the materials we use instead of study design and enables the development of error.

The kick-off

The beginning of the conscious thought of the benefits of nanotechnology developments are often attributed to Richard Feynman, Nobel, who predicted in 1959, in a lecture titled "There's plenty of room at the end," the first ideas behind nanotechnology. "I want to describe an area," Feynman began, "in which very little has been done, but done in principle in which many Dell XPS M1330 Battery things can be.

Also the most important thing that could have many technological applications. What I want is to address the problem of manipulation and control of objects in a small way "..." What are the properties of materials, if we really wanted we? I do not know exactly what was coming, but I have no doubt that if controlásemos placing objects on a small scale, would give access to a variety of properties, the existing materials Dell Studio 1536 Battery and we could have to do many things. "

But while R. Feynman had a vision as sharp, take decades to be capable of tools that make us to manipulate and observe matter to allow the develop nanoscale. For example, it was not until 1981 that G. Binning and H. Rohrer, a kind of microscope, called the STM to see that he and moving atoms for the first time. In 1986 he received the Nobel Prize for their Dell Studio 1735 Battery discovery.

Nanoart

The image of this little world again that we begin to explore, are very suggestive in terms of aesthetics and communication. All these possibilities, the exhibition "A walk through the visit of nano" at the Ethnography Museum of Castilla y León Zamora from 16 June-24. July, you can discover Dell XPS M1730 Battery for themselves the artistic proposals.
