SUMMARY:The interplay between condensation and chemistry in the format
 ion of solid particles in the ejecta of supernova explosions\, Special
  Friday Colloquium\, Davide Lazzati
DESCRIPTION:Dust is a minor component of the interstellar medium but<b
 r>
\nplays a major role in the evolution of the universe and on our<br
 >
\ncapability to observe it. Despite recent advances\, some fundament
 al aspects of the physics of formation of cosmic dust are still poorly
  understood. This leads\, for example\, to theoretical predictions of 
 dust yields from supernova explosions that are at least two orders of 
 magnitude larger than observed. In this talk I will use carbonaceous d
 ust formation in core-collapse supernovae as a case study to discuss<b
 r>
\nthe current status and recent advances on our understanding of th
 e<br>
\nphysical and chemical mechanisms at the base of the gas-solid 
 phase transition in the astrophysical environment. I will discuss diff
 erent approaches to the problem and compare their results to available
  observations. I will conclude by introducing a new framework for stud
 ying the outcomes of collisions between dust agglometates to study the
 ir compactification\, growth\, and fragmentation.<br>
