Neanderthal Declined Early

On the certificate of Guinness World Records ltd it says. The smallest made by man jet engine measures 600 nanometers in diameter and weighs 1 picogram (10 ^ kg minus 15) He was by Alex A. Solovev, Samuel Sanchez, Yongfeng Mei and Oliver G. Schmidt at the Leibniz Institute for Solid State and Materials Research (IFW Dresden), Germany, produced and demonstrated. It goes to the researchers but not so much set a record of the tiny new features rather than connect to it.


The vision of the researchers is to design and produce complex nanomachines that are as capable of transporting small amounts of drugs and targeted to deliver a suitable place. Following the example of biological organisms to artificial micromachines using the chemical energy of their environment and use it for their own transportation. For these micro-and nano-missile under its own power, the research team led by Prof. Dr. Oliver G. Schmidt already have specific ideas for self-powered micro-containers usually are titanium, iron and platinum layers of tubes of about 5 micrometers in diameter and about . rolled up 50 micrometers in length.


The innermost layer of these micro-tubes consists of platinum and simultaneously serves as a catalyst in the reaction of hydrogen peroxide to water and oxygen. This forms oxygen bubbles that are ejected from the micro-or nanotubes, and thus lead to a rapid and directed movement of the tube. By an external magnetic field can movement, acceleration and direction changes of the tubes in a very simple manner be controlled remotely. More, even the loading and unloading of the transported cargo through the micro-tubes is possible through a magnetic field and precisely controlled. In initial experiments were already up to 60 styrofoam balls and some metal nanoplates are transported through the liquid.
