(Nanowerk Information) Researchers on the College of Twente have developed a brand new technique that permits them to exactly management chemical reactions utilizing steel ions. This marks an necessary step in the direction of computer systems that perform just like the human mind. They lately revealed their findings within the scientific journal Nature Communications (“Exploring the programmability of autocatalytic chemical reaction networks”).

All residing issues can reply to their setting by means of a sequence of complicated chemical reactions. This type of data processing requires far much less vitality than that of digital computer systems. Consequently, the underlying processes are essentially completely different. For many years, researchers have been trying to find a strategy to recreate nature’s data processing utilizing molecules.

On this research, researchers from the College of Twente succeeded in imitating complicated mathematical capabilities with steel ions. This included polynomials like linear equations and parabolas, in addition to logical Boolean capabilities that produce completely different outcomes primarily based on the enter.

The researchers have been in a position to program the chemical reactions to not solely reply to present situations, but in addition ‘remember’ earlier occasions. ‘We have found a possible building block for intelligent systems,’ says researcher Albert Wong. Utilizing steel ions, the researchers managed the speed of autocatalytic reactions. These are chemical reactions that speed up themselves.
