Nanochannels and nanodroplets in polymer membranes controlling ionic transport
Matej Kanduč, Rafael Roa, Won Kyu Kim +1
Polymer materials with low water uptake exhibit a highly heterogeneous interior, characterized by water clusters in the form of nanodroplets and nanochannels. Here, based on our re…
Transport in polymer membranes beyond linear response: Controlling permselectivity by the driving force
Won Kyu Kim, Sebastian Milster, Rafael Roa +2
In the popular solution-diffusion picture, the membrane permeability is defined as the product of the partition ratio and the diffusivity of penetrating solutes inside the membrane…
Electrostatic reaction inhibition in nanoparticle catalysis
Yi-Chen Lin, Rafael Roa, Joachim Dzubiella
Electrostatic reaction inhibition in heterogeneous catalysis emerges if charged reactants and products are adsorbed on the catalyst and thus repel the approaching reactants. In thi…
Ionic structure around polarizable metal nanoparticles in aqueous electrolytes
Bendix Petersen, Rafael Roa, Joachim Dzubiella +1
Metal nanoparticles are receiving increased scientific attention owing to their unique physical and chemical properties that make them suitable for a wide range of applications in…
Tuning the Selective Permeability of Polydisperse Polymer Networks
Won Kyu Kim, Richard Chudoba, Sebastian Milster +3
We study the permeability and selectivity (`permselectivity') of model membranes made of polydisperse polymer networks for molecular penetrant transport, using coarse-grained, impl…
Enhanced Catalytic Activity of Gold@Polydopamine Nanoreactors with Multi-compartment Structure Under NIR Irradiation
Shilin Mei, Zdravko Kochovski, Rafael Roa +6
Photothermal conversion (PTC) nanostructures have great potential for applications in many fields, and therefore, they have attracted tremendous attention. However, the constructio…
