The zeolite used in this study is zeolite-Y constructed by interconnecting ‘sodalite units’ in ‘supercages’. The diameter of a pseudospherical supercage is 1.3 nm and the size of the window to the supercage is 0.75 nm. The neighboring supercages are connected through the windows in a tetrahedral symmetry. We synthesized zeolite Y with the average apex-to-apex length of 2 micrometers. equipment_required: experiment: Coherent Diffraction Studies of CdS Nanostructure in Zeolites foreign_nationals: Hyunjung Kim, Heeju Lee, (Youngseok Byun) hazards: instrument: 34ID-C coherent instrument_other: minimumdays: name: Hyunjung Kim nonmembers: submit: Submit unacceptable_dates: z34ID_details: #REMOTE_HOST: r06143.sogang.ac.kr #REMOTE_ADDR: 163.239.53.143 #CONTENT_LENGTH: 939 #HTTP_REFERER: http://www.uni.aps.anl.gov/admin/unireq.html #HTTP_USER_AGENT: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; InfoPath.1)
