The Bingham medal for 1996 will be awarded
to H. Henning Winter, Distinguished University Professor of Chemical Engineering and
Adjunct Professor of Polymer Science and Engineering at the University of Massachusetts,
Amherst. This award has been given in recognition of outstanding contributions to
experimental rheology and rheometry of gels and polymer melts.
Winter obtained his Dipl-Ing. at the University of Stuttgart, Germany, and a M. Sci. in Chemical Engineering at Stanford University. Subsequently, he earned a Ph.D. (summa cum laude) in Chemical Engineering at the University of Stuttgart and wrote his "Habilitation" for the area of Rheology. He has been a post-doctoral fellow at the Rheology Research Center at the University of Wisconsin, a Visiting Professor at the University of Minnesota and at the Max Planck Institute for Polymers in Mainz. In 1979, he joined the faculty of the University of Massachusetts where, in 1994, the Trustees of the University appointed him to "Distinguished University Professor". He has been the Editor of Rheologica Acta since 1990 and is a member of the editorial boards of the Journal of Rheology and the Journal of Non-Newtonian Fluid Mechanics.
Winter and his research group, in a series of ground breaking papers, have characterized the rheology of polymers during gelation. They discovered that the gel point of polymers is marked by self-similar relaxation at long times. This was a clear breakthrough in an area which until then had been viewed as not accessible to rheology in a quantitative way. The simplicity of the behavior at the gel point is quite striking and the behavior discovered by Winter and his group makes it easy to identify the gel point. This approach has helped many researchers in their study of solidifying materials by both chemical and physical gelation. The experimental findings have also apparently initiated a rather active development of theories for the rheology of gels, mostly in the physics community. However, these results have also had technological impact, supporting the commercial development of gels for adhesives, sealants, toners, and biological applications.
More recently, Winter and his co-workers M. Baumgartel and A. Schausberger discovered that the relaxation of linear, flexible polymers with a uniform chain length follows a scaling relation. The parameters are the plateau modulus, the longest relaxation time, and the scaling exponent. The scaling relation has potential as a starting condition for the exploration of polymers with more complicated molecular architecture including branching, polydispersity, and chain stiffness.
For generating biaxial extension in small samples, Winter invented the technique of lubricated squeezing and studied it jointly with C.W. Macosko. This simple technique was the first one to give step-strain biaxial extension data. Biaxial extension data are important for the development of constitutive equations and for selecting polymers which are suitable for polymer processing operations such as film blowing and blow molding. The method has been used in several laboratories, and it has recently been adopted for commercial rheometry.
H.H. Winter has contributed to the numerical modeling of polymer flows with a focus on technologically important areas. His 1977 paper on viscous dissipation is considered by many as a classic paper in the area. His current research interests include gelation, rheology and material structure, and rheometrical methods. A list of his publications can be found at http://www.ecs.umass.edu/che/winter.html.
The 1996 Journal of Rheology Publication Award has gone to L.B. Chen, B.J. Ackerson, and C.F. Zukoski for their paper entitled, "Rheological consequences of microstructural transitions in colloidal crystals," and published in the Journal of Rheology, 38 (2), 193-216 (1994).
Application forms for membership in the Society of Rheology can now be downloaded from the home page of the Society on the World Wide Web. The address is http://www.umecheme.maine.edu/sor/. Also available on the home page are abstracts of forthcoming papers in the Journal of Rheology and a listing of upcoming rheology meetings.
STATUS OF AND FUTURE DIRECTIONS FOR SoR
WHERE ARE WE?
WHAT (IF ANYTHING) SHOULD WE (TRY TO) CHANGE?
The first reaction of one who has been entrusted with the responsibility of presiding
over an organization is to consider its present state. If that state is sound, as I am
delighted to believe is true of SoR, then the second reaction is to worry about future
threats to its health. Let me summarize my views of SoR's current situation. The Journal
is, by all measures,
subjective and objective, highly regarded editorially, and we have successfully managed
the transition of the Editorship. The Editor's decisions on publication are based only on
quality, not on financial restrictions on number of pages. The Journal has increased
substantially in size, while the cost per page to the Libraries has been reduced, the
publication page charge to authors eliminated, and the membership dues kept constant since
1988. In addition, we have managed to build the publication reserve fund that is essential
for the above-mentioned editorial freedom, acting as a ballast to allow occasional cost
overruns in a time-averaged break-even mode of operation.
The Annual Meetings, due to the dedicated efforts of our volunteer Technical Program and Local Arrangements Committees, continue to be successful in attendance, technical content, time for presentation, and opportunity to interact with colleagues, and at a cost that is moderate in comparison with other meetings. The introduction of poster sessions has eased, to some extent, the burden of scheduling multiple parallel sessions. Further, the Short Courses given in conjunction with the Meetings continue to be popular.
The Membership of the Society has increased to a record number, which may be taken as evidence for the estimations of the soundness of the Journal and the Meetings. In addition, great credit must also be given to the energetic and effective activities of the Membership Committee in publicizing these benefits of membership. Broadening the scope of the Bulletin, and establishment of a WWW home page are efforts to increase communication with and among members of the Society.
What, then, are the threats to this happy state of affairs? One, common to all
Technical Society publishers, is the apparently inexorable decline of library
subscriptions. In the short run, the financial burden caused by this may have to be a
modest increase to the members of their share of the publication cost. On a longer time
scale, this will be compounded by the unknown effects of the inevitable growth of
electronic publishing. Our affiliation with AIP, and its cooperation with other
publishers, offers us the best hope for coping with whatever changes might occur.
Personally I am optimistic that the refereed archival journal will survive because it can
serve as a filter and as a life preserver to keep readers from drowning in a sea of
information. Such a role may suggest changes in publication policy, for example, as to
encourage more review articles. Another threat is more specific to SoR, as an
inter-disciplinary society, most of whose members belong to other, perhaps primary,
societies. As subfields mature and problems are solved, practitioners may no longer
consider SoR
membership to be important to them. They may drop out, and form rheology groups within
their primary societies. The loss to them is the lack of interaction with advances in
related subfields that may be useful to them; the loss to SoR is the lack of knowledge of
new rheological problems that may have arisen from advances in their technology. It is
clear from the limited communication from the members that the answer to this problem is
not to have additional meetings, workshops, etc. However, perhaps an answer may lie in
making use of the dormant provision in our Constitution for the formation of Divisions.
Perhaps a Division composed of members with a fairly narrow area of common interest could
act as a bridge to the members of the principal technical society (ies) devoted to that
interest; it could also co-sponsor symposia at meetings of those societies (meetings and
symposia that are now being held anyway, without SoR involvement). The risks, financial
and technical, would probably be small; the possible gain would be the broadening of our
base without greatly affecting the core Society. Your views on this proposal, and on other
topics addressed or ignored in these comments, are most welcome! My e-mail address is kfw@aip.org.

Members may or may not be aware of the process by which the technical program of an annual meeting is formulated. Decisions in this regard are made by the Chair of the Technical Program Committee in consultation with the Executive Committee of the Society. The Society is always open to suggestions from the membership regarding specific symposia topics. The person proposing a particular topic should support the case by identifying, among other things, the target audience, potential speakers and session chairs. The proposal can be forwarded to a technical program chair well in advance of the target meeting. A proposal can also be submitted to the Vice President of the Society who chairs the Meetings Policy Committee. Names of technical program chairs, when available, can be found (i) in the minutes of previous Executive Committee Meetings (ii) on the SoR home page at http://www.umecheme.maine.edu/sor/ (iii) by contacting a member of the Executive Committee. This is one way that members can shape the future direction of the Society. In this regard see also the accompanying Comments of Society President Kurt Wissbrun.
The Finnish Academies of Technology have awarded the 1995 Walter Ahlstrom Environmental Prize to Professor David Boger of the University of Melbourne, Australia for his research on non-Newtonian fluids which has resulted in the reduction of residues during aluminum production.
The Rheology Bulletin will now publish papers on the applied aspects of Rheology which are intended for the non-specialist. (Archival research papers should be sent to the Journal of Rheology which is also published by the Society of Rheology.) Appropriate topics include the application of rheological principles to a specific system, instrumentation for rheological measurements, description of interesting rheological phenomena, and the use of well-established rheological techniques to characterize products, processes or phenomena. Papers that describe the historical aspects of the practice of rheology and how these may have influenced current trends are welcome. Also welcome are papers that address the present and changing status of rheological education including papers that describe recent or current innovation in the classroom or laboratory. Consultation with the Editor prior to manuscript submission is encouraged.
Papers should ordinarily not exceed about 4000 words in length. SI units should be used, but any standard style of writing may be employed. The article must have a clear message, and the significance of the work must be explicitly stated. Submit two copies of the manuscript at least three months prior to the issue in which publication is desired. The initial decision about suitability of publication will be made by the Editor. Both solicited and contributed papers may be sent to two or more reviewers. If the paper has been published previously in essentially the same form, permission for reprinting must have been obtained from the copyright holder.
The Society has negotiated a special introductory rate for members who would like to subscribe to the American Institute of Physics magazine Computers in Physics. The special introductory rate of $39.95 for one year represents a 20% savings off AIP's regular member rate of $49.95. Since many in the Society may not be familiar with Computers in Physics, we have arranged to have AIP send a sample copy to every member. Watch for the sample copy to arrive in August. If you decide to subscribe to Computers in Physics at the special introductory rate, just mark the special check-off box that will appear on your 1997 membership dues notice. Or contact AIP at:
