One of the best means of sharing knowledge & encouraging a discussion is by giving a "Power Point" presentation to a group of people. The presentation could be annotated with figures, diagrams & colorful pictures to draw the attention of the group & to enhance their participation in the knowledge sharing process.
Here I am attaching a presentation, the very first one I made 9 years ago to give an introduction about 'Polyester Technology'. Certain slides have been removed out of respect to technology confidentiality clauses with my previous employer but the general idea is to show to students & young engineers how a presentation can generate interest & dicussion on a completely new subject for a group of people.
Subsequent to this first presentation, I have done several more & found that they help in bringing to focus a subject of common interest.
Presentations are also a great tool for 'Business Development' for any organization looking for business in a very competitive business environment.
Hope you enjoy this small presentation.

Ankur.
