Melting, bubble-like expansion and explosion of superheated plasmonic nanoparticles
Simon Dold, Thomas Reichenbach, Alessandro Colombo +32
We report on time-resolved coherent diffraction imaging of gas-phase silver nanoparticles, strongly heated via their plasmon resonance. The x-ray diffraction images reveal a broad…
Time-resolved single-particle x-ray scattering reveals electron-density as coherent plasmonic-nanoparticle-oscillation source
D. Hoeing, R. Salzwedel, L. Worbs +18
Dynamics of optically-excited plasmonic nanoparticles are presently understood as a series of sequential scattering events, involving thermalization processes after pulsed optical…
Photon Energy-Resolved Velocity Map Imaging from Spectral Domain Ghost Imaging
Jun Wang, Taran C. Driver, Felix Allum +11
We present an approach that combines photon spectrum correlation analysis with the reconstruction of three-dimensional momentum distribution from velocity map images in an efficien…
Three-Dimensional Coherent Diffractive Imaging of Isolated Faceted Nanostructures
Alessandro Colombo, Simon Dold, Patrice Kolb +29
The structure and dynamics of isolated nanosamples in free flight can be directly visualized via single-shot coherent diffractive imaging using the intense and short pulses of X-ra…
The Kinetic Energy of PAH Dication and Trication Dissociation Determined by Recoil-Frame Covariance Map Imaging
Jason W. L. Lee, Denis S. Tikhonov, Felix Allum +28
We investigated the dissociation of dications and trications of three polycyclic aromatic hydrocarbons (PAHs), fluorene, phenanthrene, and pyrene. PAHs are a family of molecules ub…
Single-shot MHz velocity-map-imaging using two Timepix3 cameras
Hubertus Bromberger, Christopher Passow, David Pennicard +10
We demonstrate the application of event-driven Timepix3-based detectors in combination with a double-sided velocity-map-imaging spectrometer to record the full 3D momentum of charg…
New aerodynamic lens injector for single particle diffractive imaging
Nils Roth, Daniel A. Horke, Jannik Lübke +17
An aerodynamic lens injector was developed specifically for the needs of single-particle diffractive imaging experiments at free-electron lasers. Its design allows for quick change…
Ignition of a helium nanoplasma by x-ray multiple ionization of a heavy rare-gas core
D. Schomas, C. Medina, L. Ben Ltaief +14
The dynamics of an x-ray-ionized two-component core-shell nanosystem is probed using doped helium (He) nanodroplets. First, a soft x-ray pump pulse selectively inner-shell ionizes…
Hindered nematic alignment of hematite spindles in viscoelastic matrices
Annemarie Nack, Julian Seifert, Christopher Passow +1
The viscoelastic behavior of composites consisting of spindle-shaped hematite particles in poly-N-isopropylacrylamide hydrogels is investigated both, by means of rheological oscill…
Depolarized light scattering from prolate anisotropic particles: the influence of the particle shape on the field autocorrelation function
Christopher Passow, Borge ten Hagen, Hartmut Löwen +1
We provide a theoretical analysis for the intermediate scattering function typically measured in depolarized dynamic light scattering experiments. We calculate the field autocorrel…
