Faculty Applied Sciences Department Radiation, Radionuclides & Reactors Date 2010-01-31 Abstract From dibenzoyl cystine, a low molecular weight gelator, we have prepared needle shaped crystals at relatively high concentrations. For the first time SESANS measurements are performed on objects with this geometry. From the measurements the average diameter can be seen directly. From a more careful analysis the width distribution is determined. The gel phase itself prepared at lower concentrations did not show any signal, in contrast to what one observes with conventional SANS. This shows the complementarity of SESANS and SANS To reference this document use: http://resolver.tudelft.nl/uuid:aeb6c32c-be42-453b-84e8-b51e2e4264cf DOI https://doi.org/10.1088/1742-6596/251/1/012035 Publisher Institute of Physics ISSN 1742-6596 Source http://iopscience.iop.org/1742-6596/251/1/012035 Source Journal of Physics: Copnference Series, 251 Part of collection Institutional Repository Document type journal article Rights (c)2010 Coumou, P.C.J.J., Brizard, A.M.A., Van Esch, J.H., De Schepper, I.M., Bouwman, W.G., Institute of Physics Files PDF 2010Coumou.pdf 1.45 MB Close viewer /islandora/object/uuid:aeb6c32c-be42-453b-84e8-b51e2e4264cf/datastream/OBJ/view
