• Ultra-sensitive tunable laser absorption spectroscopy: Applications and performance assessment ﻿

(2005)
Methodologies using tunable laser absorption spectroscopy (TLAS) for quantifying carbon dioxide stable isotopes (13/12CO 2), measuring atmospheric formaldehyde (CH2O), and analyzing exhaled carbonyl sulfide (COS) in human ...
• Ultra-short carbon nanotubes as nanocapsules for medical imaging and therapy ﻿

(2008)
This thesis details the development of ultra-short, single-walled carbon nanotubes (US-tubes) for use as nanocapsules to contain and deliver medical agents for both imaging (Gd3+ ) and therapeutic (211 At) purposes. In ...
