Panel Discussion: Power Dialog
discussing Colorado's engagement for a clean energy economy in the 21st century
The Power Dialog will support 10,000 students to participate in face-to-face dialog with state-level leaders in all fifty states about what is needed to shift to a clean energy economy. Here in Colorado, the Dialog gives students and community members a voice in critical decisions that will determine their future, and the future of the earth.

Heterogeneous Efflorescence by Mineral Dust Particles
One of the key factors that determines particle growth and heterogeneous reaction efficiency of aerosols is whether the particle is liquid or solid. Salt aerosols transition between these phases through efflorescence and deliquescence. Although homogeneous efflorescence has been studied in detail, heterogeneous efflorescence is not well understood. Here we examined heterogeneous efflorescence by optically levitating single droplets of salt solutions and exposed the droplet to a flow of mineral dust particles. The impact of mineral dust on efflorescence and the difference between immersion and contact efflorescence will be discussed.
