The spectroscopy and dynamics of microparticles.

The 137th Faraday Discussion covered a wide range of subjects divided into the four categories of Spectroscopic Techniques, Dusty Plasmas and X-Ray Characterization, Atmospheric Aerosols, and Particle Manipulation. These divisions organized the thinking into specific areas of research and allowed one to see interconnections between the two central foci of physical chemistry; techniques and applications. Physical chemists excel at developing and mastering a wide range of new techniques and applying them to a variety of tasks as the need arises. At times specific tasks present themselves and in response new techniques are developed. The presentations provided examples of both such interplays. In these remarks the presentations are summarized, common features are highlighted, and possible directions for future research are suggested.
