Autor: Matti Knaapila, Ulla Vainio, Sophie E. Canton, Gunnel Karlsson
Publikováno v: Molecules, Vol 25, Iss 22, p 5413 (2020)
We present a small-angle X-ray scattering (SAXS) study of the anisotropic photoinduced growth of silver (Ag) nanoprisms in aqueous dispersions. The growth of nearly spherical (40 nm) and thin (

Mutation-induced alterations of intra-filament subunit organization in vimentin filaments revealed by SAXS
Autor: Harald Herrmann, Tatjana Wedig, Susanne Bauch, Martha Brennich, Sarah Köster, Ulla Vainio
Publikováno v: Soft Matter. 15:1999-2008
Vimentin intermediate filaments constitute a distinct filament system in mesenchymal cells that is instrumental for cellular mechanics and migration. In vitro, the rod-like monomers assemble in a multi-step, salt-dependent manner into micrometer long

Publikováno v: Advanced Engineering Materials. 18:597-607
Conducting polymers (CP) as an active material in electrochemical actuators are often likened to “artificial muscles”. To transfer the isotropic change of volume in the CP component into an anisotropic actuation as in a natural muscle, different
