    Versatile macroscale concentration gradients of nanoparticles in soft nanocomposites

    Taladriz‐Blanco, Patricia ; Rothen‐Rutishauser, Barbara ; Petri‐Fink, Alke ; Balog, Sandor

    In: Small, 2020, vol. 16, no. 6, p. 1905192

    Nanocomposite materials benefit from the diverse physicochemical properties featured by nanoparticles, and the presence of nanoparticle concentration gradients can lend functions to macroscopic materials beyond the realm of classical nanocomposites. It is shown here that linearity and time‐shift invariance obtained via the synergism of two independent physical phenomena—translational...

    Polydopamine nanoparticle doped nanofluid for solar thermal energy collector efficiency increase

    Hauser, Daniel ; Steinmetz, Lukas ; Balog, Sandor ; Taladriz‐Blanco, Patricia ; Septiadi, Dedy ; Wilts, Bodo D. ; Petri‐Fink, Alke ; Rothen‐Rutishauser, Barbara

    In: Advanced Sustainable Systems, 2020, vol. 4, no. 1, p. 1900101

    Polydopamine can form black nanoparticles and has recently been gaining attention due to its extraordinary heating properties upon excitation with light. Herein, polydopamine hybrid nanoparticles are synthesized in different sizes and subsequently added to a solar fluid to analyze heating ability. The solar fluids with the differently sized hybrid polydopamine particles are compared to a...

    Lock‐in thermography to analyze plasmonic nanoparticle dispersions

    Steinmetz, Lukas ; Taladriz‐Blanco, Patricia ; Geers, Christoph ; Spuch‐Calvar, Miguel ; Bonmarin, Mathias ; Balog, Sandor ; Rothen‐Rutishauser, Barbara ; Petri‐Fink, Alke

    In: Particle & Particle Systems Characterization, 2019, p. 1900224

    The physicochemical properties of nanoparticles (NPs) strongly rely on their colloidal stability, and any given dispersion can display remarkably different features, depending on whether it contains single particles or clusters. Thus, developing efficient experimental methods that are able to provide accurate and reproducible measures of the NP properties is a considerable challenge for both...
