inanimate matter has a memory? It is neither amusement nor a puzzle. It is the latest finding of a Swiss scientific team working in nanotechnology , which is mainly concerned with miniaturizing things to the maximum extent. As a reminder, the name of this science is derived from the term nano, which is equal to one billionth of a thing, so a nanometer, for example, is a billionth of a meter. For the first time in the history of man's knowledge of the properties of inanimate materials, scientists have discovered a substance that can "remember" the entire history of the paths of electronic currents that cross it. It is obvious that this is directly reminiscent of computer chips , in which the ability to memorize the paths of electronic currents is the main concern of experts. In general, each electronic path in an electronic chip is equal to a specific piece of information.
And that historical discovery of the substance that "remembers" electronic tracks happened by chance! According to the newspaper "The Independent", the discovery came from the work of a team from the "Federal Polytechnic College in Lausanne" on the properties of vanadium dioxide for short, VO2 "in or 2", and its variables during the transition of that substance from one state to another. To clarify, when water boils, it turns into steam, and this is called a transition from one state to another state of water.
In the context of those experiments, a doctoral student named Muhammad Sami Zadeh Nikoo tried to document the details of what happens during the transfer of vanadium dioxide from one state to another. On the other hand, he noticed that there is something inconsistent with the theoretical data, which occurs during the passage of electric currents in vanadium dioxide, a substance frequently used in electronic chips. According to that researcher, as soon as the current of electricity passes in and out of vanadium dioxide, it returns to its first state before the current passed through it.
And by extension, when that current is passed again in vanadium dioxide, it passes more quickly, as if it "remembers the first passage of electric current and expects to cross it again", according to Professor Elison Mattioli, who supervised that research.
With scientists confirming the uniqueness of this feature in vanadium dioxide, scientists expect that it will revolutionize the electronic chip industry and its memory, which is the mainstay of its entire work. And by extension, scientists expect that this discovery will lead to an acceleration of work in the miniaturization of electronic chips, thus revolutionizing all nanotechnology sciences, especially the machines and tools that are made based on that advanced science.
