NOAA Reports Potent Greenhouse Gas Levels Off

Description: This document provides a summary of a study by NOAA researchers and National Institute for Space Research in the Netherlands. According to the study, one of the atmosphere's most potent greenhouse gases, methane, may now have leveled off. Scientists aren't sure yet if this "leveling off" is just a temporary pause in two centuries of increase or a new state of equilibrium.

Growing carbon nanotubes by chemical vapor deposition technique.

Description: Carbon nanotubes were synthesized in the laboratory using chemical vapor deposition at different methane concentration. I found that a methane concentration of 4 sccm was ideal for well recognizable carbon nanotubes. A higher concentration led to fewer nanotube growth and silicon carbide structure. Coating the sample first with Fe(NO3)3 created a catalyst base on the substrate for the nanotube to adhere and grow on.
