We now propose to bring it to APS for testing with the USAXS facility. We wish to determine the cell's potential for measuring inter-particle interactions within a flowing suspension as a function of pH and dispersant concentration, and to explore the characteristics of nanoparticulate self-assembly and agglomeration, particle surface state within a suspension, and the disentanglement of flowing carbon nanotubes. equipment_required: Interfacing of pump, probes etc with epix control computers experiment: In-Situ USAXS Studies of Flowing Suspensions. foreign_nationals: Jan Ilavsky hazards: No major hazards. Peristaltic pump, low flow rates. But closed fluid system will cover full pH range. Ultrasonic disruptor will be run peroiodically in source beaker. instrument: 33ID-D USAXS instrument_other: minimumdays: 4 name: Andrew Allen nonmembers: None unacceptable_dates: Not before March 1st, 2004 z34ID_details: #REMOTE_HOST: porcelain.nist.gov #REMOTE_ADDR: 129.6.180.24 #CONTENT_LENGTH: 1144 #HTTP_REFERER: http://www.uni.aps.anl.gov/unireq.htm #HTTP_USER_AGENT: Mozilla/4.0 (compatible; MSIE 5.0; Mac_PowerPC)
