My research project in CEN was on 2D layered nanoparticles. My lab partner and I synthesised nanoparticles of a variety of inorganic materials; WSe2, ZrS2 and TiS2. We investigated different ways to control the properties of the product nanocrystals. The use of different surfactants, and also different sources of the chalcogen in the synthesis, were studied. While the work was synthetically aimed, an understanding of the theory was also very important, and it was great that members of the group were approachable and happy to answer any questions. I really enjoyed the opportunity to have an active role in the exciting research of this group, and also the chance to explore Seoul and beyond. I am very grateful to Professor Cheon and the rest of the group for accommodating me over the 6 weeks I was an intern here.
