Description:
An x-ray surface forces apparatus for simultaneously measuring forces and structures of confined complex fluids under static and flow conditions is described. This apparatus, combined with an intense synchrotron x-ray source, allows investigation of molecular orientations within a thin liquid crystal film confined between two shearing mica surfaces 3900 angstroms apart. The layer-forming smectic liquid crystal 8CB (4-cyano-4'-octylbiphenyl) adopted a series of distinct planar layer orientations, including the bulk flow-forbidden b orientation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Idziak, S H -- Safinya, C R -- Hill, R S -- Kraiser, K E -- Ruths, M -- Warriner, H E -- Steinberg, S -- Liang, K S -- Israelachvili, J N -- New York, N.Y. -- Science. 1994 Jun 24;264(5167):1915-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17794078" target="_blank"〉PubMed〈/a〉
