Atmospheric Heterogeneous Reaction Chemistry and Theoretical Molecular Science

Advanced Electronic Structure Theory in Quantum Chemistry Department of Theoretical and Computational Molecular Science

Quantum chemistry is a subdiscipline of physical chemistry, and practicing its theory by computer is a powerful approach to chemical theory problems that are rather realistic in terms of size and behaviors. We focus on development of the electronic structure theory that is capable of supplying analytic interpretation of chemical phenomena and is being advanced so that it provides accurate infor...

Atmospheric chemistry of bioaerosols: heterogeneous and multiphase reactions with atmospheric oxidants and other trace gases

Advances in analytical techniques and instrumentation have now established methods for detecting, quantifying, and identifying the chemical and microbial constituents of particulate matter in the atmosphere. For example, recent cryo-TEM studies of sea spray have identified whole bacteria and viruses ejected from ocean seawater into air. A focal point of this perspective is directed towards the ...

Integrating reaction chemistry into molecular electronic devices.

This Focus Review provides an overview of the design and fabrication of new families of molecular electronic devices where reaction chemistry is an efficient means for covalently bridging the nanogaps between separated contacts. In each case ever-reducing top-down device fabrication existing in the silicon-based semiconductor industry is tailored to meet the requirements of ever-expanding lengt...

The oleic acid-ozone heterogeneous reaction system: products, kinetics, secondary chemistry, and atmospheric implications of a model system – a review

The heterogeneous processing of organic aerosols by trace oxidants has many implications to atmospheric chemistry and climate regulation. This review covers a model heterogeneous reaction system (HRS): the oleic acidozone HRS and other reaction systems featuring fatty acids, and their derivatives. The analysis of the commonly observed aldehyde and organic acid products of ozonolysis (azelaic ac...
