STAR Grantee's Research Highlighted in Applied Spectroscopy
The nanotechnology research of STAR grantee, Dr. Murray Johnston, is the focus of the most recent issue of Applied Spectroscopy (Applied Spectroscopy (2006) 60(10), 264A-272A), the official publication of the Society for Applied Spectroscopy. The October 2006 issue highlights the work of Dr. Johnston and his co-researchers, Shenyi Wang and Melissa Reinard, at the University of Delaware. In their article, "Focal Point: Nanoparticle Mass Spectroscopy: Pushing the Limit of Single Particle Analysis," the researchers describe approaches they have used to understand where nanoparticles in the air come from, and how they affect our health and the world around us.
Addressing issues such as these requires an understanding of particle size and chemical composition, specifically on a particle-by-particle basis, since these parameters are used to determine the sources of individual particles in air and their subsequent physical, chemical, or biological impact. Related articles are also featured in recent and upcoming issues of Analytical Chemistry (2006, 78, 1750-1754), Environmental Science and Technology (2006, 40, 1843-1848), and the International Journal of Mass Spectroscopy (in press).
The research described above is a result of a Science to Achieve Results (STAR) grant award to the University of Delaware to study the elemental composition of freshly nucleated particles. Dr. Johnston is a Professor of Chemistry in the University of Delaware's Department of Chemistry and Biochemistry, and is the recipient of a current STAR research grant investigating the near real-time speciation of organic aerosols for source apportionment.
