  • Cooperativity during Melting and Molecular Exchange in Micelles with Crystalline Cores 
    König, Nico; Willner, Lutz; Pipich, Vitaliy; Zinn, Thomas; Lund, Reidar (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    Molecular exchange processes are important equilibration and transport mechanisms in both synthetic and biological self-assembled systems such as micelles, vesicles, and membranes. Still, these processes are not entirely ...
  • How detergents dissolve polymeric micelles: Kinetic pathways of hybrid micelle formation in SDS and block copolymer mixtures 
    Myhre, Synne; Amann, Matthias; Willner, Lutz; Knudsen, Kenneth Dahl; Lund, Reidar (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Mixtures of amphiphilic polymers and surfactants are used in a wide range of applications, e.g., pharmaceuticals, detergents, cosmetics, and drug delivery systems. Still, many questions remain on how the structure and, in ...
  • Nanoscopic confinement through self-assembly: Crystallization within micellar cores exhibits simple Gibbs-Thomson behavior 
    Zinn, Thomas; Willner, Lutz; Lund, Reidar (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)
    It is well known that liquids confined to small nanoscopic pores and droplets exhibit thermal behavior very different from bulk samples. Less is known about liquids spontaneously confined through self-assembly into micellar ...
  • Spherical Micelles with Nonspherical Cores: Effect of Chain Packing on the Micellar Shape 
    König, Nico; Willner, Lutz; Carlström, Göran; Zinn, Thomas; Knudsen, Kenneth Dahl; Rise, Frode; Topgaard, Daniel; Lund, Reidar (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Self-assembly of amphiphilic polymers into micelles is an archetypical example of a “self-confined” system due to the formation of micellar cores with dimensions of a few nanometers. In this work, we investigate the chain ...
  • Stability of Nanopeptides: Structure and Molecular Exchange of Self-assembled Peptide Fibers 
    König, Nico; Szostak, Szymon Mikolaj; Nielsen, Josefine Eilsø; Dunbar, Martha; Yang, Su; Chen, Weike; Benjamin, Ari; Radulescu, Aurel; Mahmoudi, Najet; Willner, Lutz; Keten, Sinan; Dong, He; Lund, Reidar (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Often nanostructures formed by self-assembly of small molecules based on hydrophobic interactions are rather unstable, causing morphological changes or even dissolution when exposed to changes in aqueous media. In contrast, ...
  • Tale of Two Tails: Molecular Exchange Kinetics of Telechelic Polymer Micelles 
    König, Nico; Willner, Lutz; Pipich, Vitaliy; Mahmoudi, Najet; Lund, Reidar (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Telechelic polymers contain two chain ends that are able to promote self-assembly into “flowerlike” or interconnected micellar structures. Here, we investigate the molecular exchange kinetics of such micelles using ...
