Andersson, R. (author), Bouwman, W.G. (author), Luding, S. (author), De Schepper, I.M. (author)Extracting structure and ordering information from the bulk of granular materials is a challenging task. Here we present Spin-Echo Small Angle Neutron Scattering Measurements in combination with computer simulations on a fine powder of silica, before and after uniaxial compression. The cohesive powder packing is modeled by using molecular...journal article 2008

Andersson, R. (author), Bouwman, W.G. (author), Luding, S. (author), De Schepper, I.M. (author)Spin-echo small-angle neutron scattering is able to characterize powders in terms of their density density correlation function. Here we present a microstructural study on a fine cohesive powder undergoing uniaxial compression. As a function of compression, we measure the autocorrelation function of the density distribution. From these...journal article 2008
