SEMINAR: Bayliss Seminar Series: Dr Dino Spagnoli

My research interests over the last 4 years have been in three distinct and different areas. In this talk I will highlight the recent progress made in all three areas.

S1. Chemical properties of the (001) β-Ga2O3 surface Monoclinic β-Ga2O3 is an n-type semiconductor with applications as a transparent conducting oxide for use in UV optoelectronic devices and various chemical sensors. We explore the most stable surface terminations providing insight into the nature of the surface and the chemical reactivity that can help improve sensor performance.   S2. Probing the aggregation of polyaromatic hydrocarbons Certain stars are surrounded by and envelope of dust, which contain polycyclic aromatic hydrocarbons (PAHs). These molecules are thought to go on to form dust particles in space but the mechanism of how this occurs is yet to be determined. Using computer simulations, we study the aggregation of PAHs, in particular the role of benzene in the clustering of larger particles.   S3. Research methods to improve the first year chemistry laboratory experience for students The laboratory component is a vital part of a science undergraduate major. We have been surveying students in 1st year chemistry units for the past three years and identified areas that require attention. This part of the talk will identify what issues were discovered and what evidence based methods we used to improve the student laboratory experience.
