Journal ArticleDOI
Silver nanowires as surface plasmon resonators.
Harald Ditlbacher,Andreas Hohenau,Dieter Wagner,Uwe Kreibig,Michael C. Rogers,Ferdinand Hofer,Franz R. Aussenegg,Joachim R. Krenn +7 more
TL;DR: It is demonstrated that the nonradiating character of the silver nanowires together with minimized damping due to the well developed wire crystal structure allow them to apply as efficient surface plasmon Fabry-Perot resonators.
Journal ArticleDOI
Echoes in x-ray speckles track nanometer-scale plastic events in colloidal gels under shear
Michael C. Rogers,Kui Chen,Lukasz Andrzejewski,Suresh Narayanan,S. Ramakrishnan,Robert L. Leheny,James L. Harden +6 more
TL;DR: In this paper, x-ray photon correlation spectroscopy experiments on a concentrated nanocolloidal gel subject to in situ oscillatory shear strain were performed, showing that the peak amplitude decays exponentially with the number of shear cycles, signaling irreversible particle rearrangements.
Journal ArticleDOI
Buoyant plumes and vortex rings in an autocatalytic chemical reaction.
TL;DR: In this type of autocatalytic plume, entrainment assists the reaction, producing new buoyancy which fuels an accelerating plume head which detaches from the upwelling conduit, forming an accelerating, buoyant vortex ring.
Journal ArticleDOI
Microscopic signatures of yielding in concentrated nanoemulsions under large-amplitude oscillatory shear
Michael C. Rogers,Kui Chen,Matthew J. Pagenkopp,Thomas G. Mason,Suresh Narayanan,James L. Harden,Robert L. Leheny +6 more
TL;DR: In this paper, x-ray photon correlation spectroscopy (XPCS) experiments on a series of concentrated oil-in-water nanoemulsions with varying droplet volume fraction subjected to in situ steady-state large-amplitude oscillatory shear (LAOS).
Journal ArticleDOI
Direct Measurement of Microstructural Avalanches during the Martensitic Transition of Cobalt Using Coherent X-Ray Scattering
TL;DR: Heterogeneous microscale dynamics in the martensitic phase transition of cobalt is investigated with real-time x-ray scattering, showing that the kinetics is dominated by discontinuous sudden changes-avalanches.
