Title: Modeling of Formaldehyde Maser Variability in Massive Star-Forming Regions


Formaldehyde (H2CO) masers are rare astrophysical phenomenon associated with massive star-forming regions. The H2CO masers associated with the star-forming regions of NGC 7538 and IRAS 18566+0408 have shown periodic variability due to a currently unknown mechanism. Our work attempts to demonstrate that a simple geometric model of the H2CO regions may account for this variability.

Title: Using Magnetic Force Microscopy to Study Magnetic Ordering of Functionalized Doped Multi-Wall Carbon Nanotubes


Carbon nanotubes are well known for their superior chemical, mechanical, thermodynamic, and electrical properties. Due to these unique characteristics, the potential applications are almost endless. In particular, carbon nanotubes are of great use for conductive and high strength nano-composites, bio-sensors, and targeted delivery of bio-active substances. In this talk, I will introduce the experimental methods used to image the carbon nanotubes. A highly ordered magnetic pattern is essential to the effectiveness of any application using carbon nanotubes, and producing an image of them is one way to ensure the viability of the sample.
