20.500.12556/RUL-103641 Complex electric double layers in charged topological colloids Charged surfaces in contact with liquids containing ions are accompanied in equilibrium by an electric double layer consisting of a layer of electric charge on the surface that is screened by a diffuse ion cloud in the bulk fluid.This screening cloud determines not only the interactions between charged colloidal particles or polyelectrolytes and their self-assembly into ordered structures, but it is also pivotal in understanding energy storage devices, such as electrochemical cells and supercapacitors. However, little is known to what spatial complexity the electric double layers can be designed. Here, we show that electric double layers of non-trivial topology and geometry -including tori, multi-tori and knots- can be realised in charged topological colloidal particles, using numerical modelling within a mean-field Poisson-Boltzmann theory.We show that the complexity of double layers -including geometry and topology- can be tuned by changing the Debye screening length of the medium, or by changing the shape and topology of the (colloidal) particle. More generally,this work is an attempt to introduce concepts of topology in the field of charged colloids, which could lead to novel exciting material design paradigms. physical chemistry charged surfaces colloids electric double layers fizikalna kemija površinski pojavi koloidi električna dvojna plast true false false Angleški jezik Slovenski jezik Neznano 2018-09-20 12:57:33 2018-09-20 12:57:33 2022-08-16 03:43:23 0000-00-00 00:00:00 2018 0 0 10 str. art. no. 14119 Vol. 8 Sep. 2018 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 544.6/.7 2045-2322 10.1038/s41598-018-32550-8 3239524 18727432 RAZ_Everts_Jeffrey_Christopher_i2018.pdf RAZ_Everts_Jeffrey_Christopher_i2018.pdf 1 B0F57518211E29AE4FE2EEC16FB9BCB4 4ed61dc4c1bfa604d83661d5aed0c2ad2abd1c0e4e36d97e0a5d59a5e6d72a4b dd67547b-a1b5-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=114104 https://www.nature.com/articles/s41598-018-32550-8 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=141297 Fakulteta za matematiko in fiziko 0 0 0
