We investigate proton-charge mobility in nanoscopic water droplets with tuneable size. We find that the diffusion of confined proton charges causes a dielectric relaxation process with a maximum-loss frequency determined by the diffusion constant. In

Comparison of iterative desmearing procedures for one-dimensional small-angle scattering data
Autor: Thomas Vad, Wiebke F. C. Sager
Publikováno v: Journal of Applied Crystallography. 44:32-42
Two simple iterative desmearing procedures – the Lake algorithm and the Van Cittert method – have been investigated by introducing different convergence criteria using both synthetic and experimental small-angle neutron scattering data. Implement

Publikováno v: Journal of Applied Crystallography. 43:686-692
A dilute dispersion of charge-stabilized, monodisperse silica nanoparticles has been used to determine the instrumental resolution function parameters of a conventional small-angle neutron scattering instrument in pinhole geometry over the entire acc

Publikováno v: Soft matter 10(47), 9511-9522 (2014). doi:10.1039/C4SM01935K
The self-assembling behaviour of 2.6 nm thin PbCO3 nanoplatelets with discorectangular shape and uniform width and thickness occurring after their formation in nonionic water-in-oil microemulsions has been investigated using synchrotron small angle X

Journal of Chemical Physics, 141(18). American Institute of Physics
We study the reorientation dynamics of liquid water confined in nanometer-sized reverse micelles of spherical and cylindrical shape. The size and shape of the micelles are characterized in detail using small-angle x-ray scattering, and the reorientat

Publikováno v: Journal of Chemical Physics, 113(4), 1651-1665
A method for nonlinear fitting of x-ray scattering data from polydisperse mixtures was developed. It was applied to the analysis of the structural changes in the droplet phase of oil-rich water-in-oil (w/o) sodium bis(2-ethylhexyl) sulfosuccinate (AO
