Employees of the Technion Israel Institute of Technology Haifa raised gold in the laboratory. Creature artificial precious metal is the result of many years of experience Maria Koyfman-Kristosof – graduate student of the local materials department and engineering. The work was led by Professor Boaza Pokroy. About Achievement Israeli scientists are told in the latest issue of the scientific journal “Nature Communications”.
To begin with, it’s worth saying that the Technion is hardly not the best institute of the country and one of the most prestigious higher educational institutions of the planet. The institution was opened in 1924, and with since then hundreds of thousands of scientists and engineers have left its walls. Exactly at Israeli Institute of Technology discovered quasicrystals and invented optical fibers. Institution staff also contributed a tremendous contribution to the development of such a field of natural science as chemistry. Therefore, it is not surprising that it is here scientists managed for the first time in human history to receive artificial gold.
Maria Koyfman-Christopher told reporters that when creating in the laboratory, experts pursued gold purely scientific interests, but the results exceeded all of them expectations, so scientists have already thought about practical infliction artificial metal. Material, as it turned out, is not only not inferior in its characteristics to real gold, but also surpasses it in some respects.
Artificial metal is in the form of a porous single crystal, which due to the presence of a continuous crystal lattice has undeniable advantages over polycrystals. To these The benefits in particular include resistance to higher temperatures, improved mechanical strength, as well as increased heat and electrical conductivity.
Despite the fact that this material is unlikely to be used for making jewelry, artificial gold can find wide application in microelectronics, dentistry and pharmacology, becoming a cheaper and better substitute natural precious metal.
We add that scientists from Switzerland (Higher Technical School Zurich) created a completely “airy gold”, which does not even sink in coffee, because this airgel is slightly lighter than cream. This unique non-material is a thousand times lighter and softer than natural gold, it can even be wrinkled with hands, nevertheless it looks “airy gold “is difficult to distinguish from the present, it even has a characteristic for this precious metal shine and charm.

Swiss scientists suggest that their artificial “gold” will find wide application, for example, in the production of jewelry products and watches, in the chemical industry, and so on.
