MIT/WHOI graduate student Desiree Plata uses a flame torch to prepare samples for carbon isotope measurements. Her experiments have shown that carbon nanotubes made by different manufacturers have distinctive chemical characteristics. That makes it harder to track the material in the environment. Her research was published March 21, 2007, in the journal Nanotechnology. (Kristin Pangallo, MIT/WHOI )
