Remarks:

Deadline for sending contributions to the paper is June 15.

The next Meeting is scheduled for October 11 – 15 with a break for individual work or excursions on Wednesday afternoon. The main goal of the next meeting is to finalize the publication. We will also have a presentation on the optical properties of nano dust.

Suggested topics for specific discussions (beyond the topics covered in the paper) (tbc):
- collision process and formation of nano dust
- comparison of different instrument capabilities (if we have new results)
- discuss charging: empirical models, molecular and atomic approach in contrast
- what do we know about shape, structure and chemical composition of the nano dust
