Polymer Processing Society Meeting at Quebec City, August 14-17, 2005.

The research of HfMI in the processing area was presented at the PPS 2005 meeting. Prof. Kalyon was a session organizer in the Processing of Composites and Filled Systems session and delivered the key note address in the Processing of Energetic Materials session of the conference along with two additional papers on the processing of nanocomposites and processing of suspensions of hydrogel binders with nanoparticles.

AICHE Annual Meeting 2005, Cincinnati, Ohio

HfMI continued to play a key role in the Safety and Processing of Energetic Materials session of the annual AICHE meeting at Cincinnati, Ohio (October 31- November 3, 2005) with five joint papers with US Army, Naval Surface Warfare Center and Material Processing & Research, Inc. The papers appeared in the proceedings volume of the meeting. The participants of HfMI in the session included Dr. Kalyon, Dr. Malik and Dr. Gevgilili.

Furthermore, Dr. Degirmencibasi, Mr. Demirkol, Dr. Malik and Dr. Kalyon presented an additional four papers in the areas of mathematical modeling of the co-rotating twin screw extrusion flow, the mixing and rheology of nanocomposites of clay/polyolefins, and the in-situ synthesis and characterization of hydroxyapatite nanoparticles.

April 23-27, 2006

HfMI is committed to participate in the 2006 World Congress of Particle Technology to take place in Orlando, Florida. This event is held once in every four year cycle, switching locations between three continents.

HfMI/ARMY/NAVY Workshop on co-extrusion of concentrated suspensions May 3, 2005 at SIT

A day-long workshop was held at Stevens Institute of Technology to cover the work done by HfMI in the area of co-extrusion of concentrated suspensions. The viscoplasticity and the wall slip of such suspensions render their co-extrusion a challenge. The workshop was attended by the representatives of the US Army Picatinny TACOM and Naval Surface Warfare Center, Indian Head Division.
