Spinon confinement in a quasi-one-dimensional anisotropic Heisenberg magnet
ddc:530
Confinement is a process by which particles with fractional quantum numbers bind together to formquasiparticles with integer quantum numbers. The constituent particles are confined by an attractive interactionwhose strength increases with increasing particle separation and, as a consequence, individual particles arenot found in isolation. [...]

Discussion on data correction for Polarization Analysis with a 3 He spin filter analyzer
ddc:530
Fully polarized neutron reflectometry and grazing incidence small angle neutron scattering are effective methods to explore magnetic structures on the nm to μm length scales. This paper is an outline of how to fully correct for the polarization analysis (PA) inefficiencies of such an instrument and to determine the error contributions of the neutron polarizer and analyzer. [...]

Magnetic targeting to enhance microbubble delivery in an occluded microarterial bifurcation
ddc:570
Ultrasound and microbubbles have been shown to accelerate the breakdown of blood clots both in vitro and in vivo. Clinical translation of this technology is still limited, however, in part by inefficient microbubble delivery to the thrombus. [...]

Nanoscale rheology at solid-complex fluid interfaces
ddc:000
Here we present an approach to measure dynamic membrane properties of phospholipid membranes close to an interface. As an example we show results of the membrane dynamics of a phospholipid membrane multilayer-stack on a solid substrate (silicon). [...]

Hydrostatic pressure effects on the static magnetism in Eu(Fe$_{0.925}$Co$_{0.075}$)$_{2}$As$_{2}$
ddc:000
EuFe2As2-based iron pnictides are quite interesting compounds, due to the two magnetic sublattices in them and the tunability to superconductors by chemical doping or application of external pressure. The effects of hydrostatic pressure on the static magnetism in Eu(Fe0.925Co0.075)2As2 are investigated by complementary electrical resistivity, ac magnetic susceptibility and single-crystal neutron diffraction measurements. [...]

Spin dynamics of the magnetocaloric compound MnFe$_{4}$ Si$_{3}$
ddc:530
The magnetic excitation spectrum of the magnetocaloric compound MnFe4Si3 has been investigated by means of polarized and unpolarized inelastic neutron scattering on single crystals. Spectra were collected in the ferromagnetic phase (TC≈305K), as well as in the paramagnetic state, in order to understand the nature of the magnetism in MnFe4Si3. [...]

Chapter 10: Neutron Scattering on different states of polymer/clay compounds: Fromsolution to dry states.
Clay-Polymer Nanocomposites Amsterdam : Elsevier Science, 327-362 (2017)
Nanocomposites [1] in general have gained importance in nowadays products leading to improved performance of these complex compound materials. The structure of the solid particles is not limited in terms of shape in advance, but their specific function is tightly connected to their shape. [...]
