Query: Astrochemistry of dust, ice and gas: introduction and overview   A brief introduction and overview of the astrochemistry of dust, ice and gas
and their interplay is presented, aimed at non-specialists. The importance of
basic chemical physics studies of critical reactions is illustrated through a
number of recent examples. Such studies have also triggered new insight into
chemistry, illustrating how astronomy and chemistry can enhance each other.
Much of the chemistry in star- and planet-forming regions is now thought to be
driven by gas-grain chemistry rather than pure gas-phase chemistry, and a
critical discussion of the state of such models is given. Recent developments
in studies of diffuse clouds and PDRs, cold dense clouds, hot cores,
protoplanetary disks and exoplanetary atmospheres are summarized, both for
simple and more complex molecules, with links to papers presented in this
volume. In spite of many lingering uncertainties, the future of astrochemistry
is bright: new observational facilities promise major advances in our
understanding of the journey of gas, ice and dust from clouds to planets.
