Authored by Jes K. Jurgensen, Arnaud Belloche and Robin T. Garrod, this
PDF delves into the role that astrochemistry plays in the process of star
formation. Recent advances and challenges in the field are addressed, with a
focus on chemical inventories in star-forming regions. Chemical differentiation
and the evolution of the protostar under physical conditions are addressed by
the authors, who underscore fractionation as one of the processes. The
communication of physical and chemical aspects of star formation is made by the
document as it exposes the reader to such complicated interactions which finally
end in the emergence of stars and development of chemical complexity in space.

The review by Duncan V. Mifsud
and other authors points at the role which sulfur plays in the special world of
astrochemistry as an element of paramount importance to biological systems and
planetary geology. A pdf of laboratory studies involving sulfur-bearing
molecules include spectroscopy and results from experiments on thermal and
photochemical processing. Charged particle bombardment and radiolysis of sulfur
ice analogues are discussed for a better understanding of the behavior of sulfur
in extraterrestrial environments. The current document concludes with proposed
further research directions and continues to highlight the importance of sulfur
in astrochemical processes.

This is a lecture note by Prof. Jesse Kroll, focusing on chemical
transformations in trace species of Earth's atmosphere. The note highlighted how
human activity impacts both air quality and climate-from covering major concepts
such as photochemistry and ozone-depleting compounds to aerosol chemistry. The
note provides a comprehensive summary of what drives atmospheric chemistry, from
sources and sinks of greenhouse gases to names and processes. The paper is
designed for better understanding of the atmospheric processes concerning
anthropogenic influences and their implication in environmental science.
