Congratulations to Martin for the publication in J. Mater. Chem. C of his new paper on nematic liquid crystals doped with gold nanoparticles, entitled "Nanoparticles dispersed in liquid crystals: Impact on conductivity, low-frequency relaxation and electro-optical performance". The paper deals specifically with the effect of the nanoparticles on the dielectric and conductive behavior of the composite, finding that the doping has negligible effect on the permittivity as such, but it comes with an ionic contamination that leads to electrode polarization build-up and increased low-frequency conductivity. This means that the low-frequency electrooptic response is also negatively affected by the doping. Read the paper here.
