From the journal Chemistry International

The 23rd World Forum on Advanced Materials (POLYCHAR) (derived from Polymer Characterization) returned to the United States for the first time since 2003, when this Conference began changing venues annually. Previously, it had been hosted by the University of North Texas for the 11 years from its founding in 1992 by Witold Brostow, Michael Hess, and Kevin Menard. In the year 2015 POLYCHAR was hosted by the University of Nebraska, Lincoln (UNL), USA, and organized by a local organization committee (the Department of Mechanical & Materials Engineering and the College of Engineering) and an international organization committee with members from Belgium, France, South Korea, and Nepal, chaired by Prof. Mehrdad Neghaban (UNL). The conference was supported by IUPAC, the IUPAC Polymer Division (Samsung Fund), the American National Science Foundation, the University of Lincoln (UNL), the Office for Research and Educational Development (UNL), the College of Engineering (UNL), the Department of Mechanical & Materials Engineering (UNL), the City of Lincoln Convention and Visitors Bureau, and the John A. Woollam Company.

Previous conferences have been held in Denton, Texas; Guimaraes, Portugal (2004); Singapore (2005); Nara, Japan (2006); Buzios, Brazil (2007); Lucknow, India (2008); Rouen, France (2009); Siegen, Germany (2010); Kathmandu, Nepal (2011); Dubrovnik, Croatia (2012); Gwangju, South Korea (2013); and Stellenbosch, South Africa (2014).

In 2015, there were six Plenary Lectures (two Young Scientists Plenaries), the Flory Medal Talk, and 13 individual Sessions in two parallel events:

These Sessions included 87 oral contributions (including 10 keynote speakers and 14 invited speakers), and 45 Posters in one session, with 103 registered participants (including 42 students) from 21 countries and 5 continents. In addition to the US, there were participants from France, Belgium, Nepal, Singapore, Poland, South Korea, Germany, Japan, China, Malaysia, Austria, Portugal, Canada, India, Georgia, Colombia, China (Taiwan), Mexico, and Ireland.

Limited funds were granted by IUPAC for the support of graduate students and young scientists from underprivileged countries. However, due to high expectations by the applicants and visa problems, it was only possible to support one young scientist in the end:

Bishnu Prasad Neupane, School of Health and Allied Sciences, Pokhara University, Nepal: Conversion of Waste Paper into BioplasticsPoly(lactic acid)

Mehrdad Neghaban, his colleagues, and collaborators at the University of Nebraska, Lincoln, deserve our thanks for their effective organization of the Course and the Conference. Good organization is a necessary condition for a creative and comfortable atmosphere, which was appreciated by the participants in Lincoln.

POLYCHAR 24 is scheduled for Poznan, Poland, end of April/early May 2016, POLYCHAR 25 is planned in Kuala Lumpur, Malaysia, 2017.
