Abstract: The present invention relates to a method for manufacturing an ink comprising n-type conducting polymer, said method comprising the steps of: a) providing a catalyst or a catalyst precursor: b) oxidizing said catalyst precursor by means of an oxidizing promoter thus obtaining said catalyst: c) adding a monomer to a solvent system comprising a polar aprotic solvent in the presence of said catalyst, thus providing a reaction solution: d) allowing the monomer to polymerize in said reaction solution thus obtaining an ink comprising n-type conducting polymer, wherein said catalyst is a quinone comprising at least one branched side chain comprising at least one chiral centre.

Abstract: A device and method for detecting a phase transition between a liquid phase and a solid phase of a substance include a pair of electrodes, a sensing layer arranged in an electrical path between the pair of electrodes, and means for measuring a first electrical characteristic of the electrical path. The sensing layer includes a mixed ion and electron conducting composite material. The composite material has an electrical property, in particular electrical resistance, which shows a peak variation as a function of time at the phase transition, such as an onset of ice formation. Computing means process the first electrical characteristic to indicate an occurrence of the phase transition.

Abstract: The present invention relates to a method for manufacturing a dispersion solution comprising nanoparticles of a rigid conjugated polymer having a dihedral angle from 0° to 20°, the method comprising the steps of: a) dissolving the rigid conjugated polymer in a first solvent system; b) combining the dissolved rigid conjugated polymer with a second solvent system thus obtaining a precipitate comprising the rigid conjugated polymer; c) collecting the precipitate comprising the rigid conjugated polymer; d) re-dispersing the precipitate in a third solvent system thus obtaining a dispersion solution comprising nanoparticles of the rigid conjugated polymer.
