Launch of several microns in length moves, throwing out of the ...
California Group nanotechnologists, led by Professor Joseph Wang (Joseph Wang) has recently presented an amazing microscopic device - the first ever self- moving mikroraketu on jet-powered hydrogen bubbles.
The device requires no power source other than a fairly high acidity of the environment. Maximum speed ... For us it is only about 0.0038 km / h, but for ...
The appearance of it - is a significant step towards a long-awaited nano-robots that can move our bodies (or at least in the stomach with its high acidity ), and ... Especially since the authors constructed a system is able to accurately throw the right place to put it to collect the goods, or other.
Each such ... The inner surface is dotted with its zinc atoms, which provide the movement: in the acidic environment of the zinc gives the audience a number of protons, electrons, and restores them to molecular hydrogen, which forms bubbles escaping from the jet ...
It is clear that the activity of this system is limited to only certain rather narrow range of pH, but this falls into the range of excellent acidity of human gastric. And this time the engine is 10 to 120, depending on the rate of ...
More subtle features ... The outer surface of the cones to cover the authors came up with a ferromagnetic layer, which is acting on the magnetic field can control the direction of movement. And, with great precision: in the course of an impressive demonstration of the scientists, ...
