The principles results are "The series of the NP of varying shape and rather narrow in size distribution were obtained: д)Magnetic ferrous oxide and cobalt ferrite (nanospheres 5-7, 10-14, 20-26 нм); -ferrous oxide (nanorods 150-200 нм); the cobalt ferrite nanoplatelets (40-120х10 нм), cobalt nanorods (3-5 35-80 nm) е)Semiconductor luminescent spherical CdSeZnS (3-4 nm) nanoparticles and elongated СdSeCdS (4-7 25-60 nm) oThe general structure was proposed and series of effective surfactants was obtained (containing monomesogenic core, dendronized) that are disclosed a way to preparation of the dispersion of relatively small zise NP (5-20 nm) in LC, that are stable with time. A marked enhancement towards esxternal magnetic field in dispersion of magnetic nanorods in LC at NP concentration not exceeded 0.01 % Product Description popup.authors Ващенко В.В.
