研究领域

The research in this group seeks to probe important atmospheric, physical and analytical chemistry problems using UV-Vis and infrared spectroscopic techniques. The key goals are to sensitively and quantitatively detect trace gases and reactive intermediates, and to begin to probe the nucleation and chemical composition of particulate matter (aerosols). Accurate monitoring of trace gases has a variety of important real-world applications ranging from biomedical sensing to explosives detection and the determination of the chemical makeup of the atmosphere. The Beames group aims to develop spectrometers for use in each of each of these areas; providing highly sensitive real time detection of many different chemical species. In addition, these spectrometers will be combined with state of the art optical trapping techniques in an attempt to provide new insights into particulate matter formation and composition.
