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

All dwelling issues can reply to their setting via a sequence of advanced chemical reactions. This type of data processing requires far much less power than that of digital computer systems. Consequently, the underlying processes are essentially totally different. For many years, researchers have been looking for a solution to recreate nature’s data processing utilizing molecules.

On this examine, researchers from the College of Twente succeeded in imitating advanced mathematical capabilities with metallic ions. This included polynomials like linear equations and parabolas, in addition to logical Boolean capabilities that produce totally different outcomes based mostly on the enter.

The researchers have been capable of 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 metallic ions, the researchers managed the speed of autocatalytic reactions. These are chemical reactions that speed up themselves.
