rhe Gordon Research Conference on "Dynamics of Macromolecular andPolyelectrolyte Solutions" was held 12-16 February, 1990, at Cass SirensHotel, Oxnard, CA. There were ninety-one scientists participating, includingthirty-four academics from the U.S.; twenty-five academics from eight foreigncountries; fourteen graduate students and postdoctoral fellows; eighteenrepresentatives from industry (12 domestic, 6 foreign). Twenty orapresentations were given and forty posters were presented. Several themesfrom the posters were discussed at Thursday evening's session. During boththe formal post-presentation discussions and the informal small discussionsessions held in front of posters (and elsewhere in the hotel), the quantityand quality of the discussions were excellent

the formal post-presentation dlscussions and tke Informal %^411 discussionsessions held In front of posters (4fd Ilnqwhere in the hotel), the quantityand quality of the discussions were eacellent

Most attendees were either chemists. Physicists or biologists, with asmall representation from chemical engineering or materials vclance

departments. Almost all of the experimentalists in attetndace emloyscattering techniques In their owi research programs. bvt other tsrchnquos

such as transient electric birefringence. dire<t Imaging of colloidaldispersions, direct measurement of intermolecular forces by the OI-motic itressmethod, and rheologlcal measuroments wore wvll-rpresented among both

attendees and speakers, In addition, there was a good balance betwt,experimentalists and theoreticians-

Two sessions on Monday, 1? Feb.. were devoted to the study of organized

assemblies (micelles. microtmulsions) by small-angle neutron scattering (SANS)measurements on shear-aligned samples, by neutron spin-echo Spectroscopy(dynamic SANS) and freeze-fracture electron microscopy Characterization ofthe first reverse micellar solution to show polymerlike behavior was announced

(Schurtenberger/Magid), and a self-consistent theory to fit static and dynamicSANS data from microemulsion droplet systems was discussed (Farago/Safran).The study of polymer dynamics by neutron spin-echo was the topic of Tuesday

evening's session, with an elegant comparison of linear and star-branchedpolymers being presented by Huang.

In Wednesday evening's session, Iaret and Weitz presented an elegant

pair of lectures on the theory and applications of dynamic multiple lightscattering from Brownian particles. On Friday morning, Pusey considereddynamic light scattering by nonergodic media, In which the scattering elementsundergo restricted motions about fixed average positions. Ewamples arepolymer gels and colloidal glasses.

Overall, the Conference was highly successful. The Chairman received

several compliments on the scientific program. Furthermore, it was gratifyingto observe a number of new collaborations being established.
