Carbon Nanotubes SEM (140,721 x). TEM (100K x). HRTEM (300K x). We adapted an established chemcial vapour deposition method, and used C14-labeled methane as the feedstock gas and went through the synthesis procedure and obatined radio-labled multi-walled carbon nanotubes.

Iron Nanoparticles 20 nm To achieve those desirable features, we have lately developed a approach to simultaneously synthesize and immobilize zero iron nanoparticles. This approach invovles four general steps. Preassemble polyelectrolyte multilyers using LbL self-assembly. Poly(allylamine hydrochloride) Then we dip the support material in ferrous sulfate solution. Some iron 2+ will complex to the polyelectrolyte multilayers through ion exchange. Pay attention to PAA, which is a weak acid. This allows us to manipulate the size of the particles, which I will discuss later. 1. Huang et al. 2008, Environ. Sci. Technol. 2. Xiao et al. 2009, ACS Applied Materials 3. Shen M. et al. 2009, J.
