Russian Physics grown graceful nano- and microstructures of metals. Recently Physics presented a paper in which studied the growth process nanoshtyrey electrochemical method in porous membranes.

A side effect of this work are wonderful pictures of micro- and nanostructures (which, by the way, it can be used in optics, medicine, electronics).

Nanowires, as its name implies, has a diameter on the order of a nanometer, that is one billionth of a meter. Today, it is able to receive the nanowire thickness from 60 to 30 nanometers. At this size, nanowire begin to play an important role various quantum effects, so it has very unique properties.

To get the nanowire, the traditional methods of manufacturing the wire are not suitable, and have to turn to chemistry - nanowire grown by chemical reactions.

There are several ways of growing nanowires. In one special plastic is first subjected to bombardment by particles accelerated to high energy, to form ultrafine pores. Then, the resulting porous plastic is applied on a copper substrate, both layers were placed in plating solution and current is passed therethrough. Under the influence of electric field copper ions penetrate into the smallest pores, and therein gradually increases very fine nanowire. To remove the nanowire from the plastic form, it is dissolved by means of special reagents.

Work with nanowire is still at an experimental stage. With this wire, scientists hope to create a new generation of computer technology.

Flowers and needles

Experimenting with the nanowire, Galina Strukov and colleagues from the Institute of Solid State Physics in Chernogolovka received a surprisingly beautiful and unusual structures.

During these experiments, the metal allowed to go beyond the plastic mold. Get the opportunity to "grow" a free, became a metal forming fanciful structures resembling coral and flowers.

Roots

To grow such metal nanotsvety nanopaporotniki scientists and alternated layers of different metals: indium, palladium, lead, nickel.

Galina Strukova suggests that the metal forms a structure similar to biological objects, because the whole process is regulated by similar growth rules. With the growth of a living plant cell produces a daughter cells which are laminated on each other, and during the growth of the metal flower metal atoms are laminated on each other.

Silver twig

In the words of a prominent Soviet physicist Lev A. Artsimovich: "Science - the best way to satisfy a personal curiosity at public expense." And the result was really very interesting.

"Shell" of palladium-nickel alloy

However, the same Artsimovich a good reason to say that "the success of the golden apple appears frequently on the most inconspicuous twig mighty tree of science." Therefore, it may be, in the near future, these fantastic metallic colors bring at least a fantastically useful fruit.
