Image: Anne Günther (University of Jena) - Physicists from Friedrich Schiller University Jena, together with colleagues from Düsseldorf, Gothenburg, Lyngby and Trieste have developed an ingenious solution for separating bonded nano-components. Their idea is to immerse the nano-components in a solvent near its critical point. In the experimental setup, they succeeded in separating the components in a controllable fashion by only changing the temperature of the solvent. The authors present their successful experiment in the scientific journal "Nature Physics". Components seperate at the critical point of the solution. "We were looking for a solution to eliminate the undesirable static friction of the individual components in a nano electromechanical system (NEMS) rubbing against each other," explains Dr Falko Schmidt from the University of Jena's Institute of Applied Physics.
