MSE PhD student Kathrina Lois Taaca attended the 21st International Vacuum Congress (IVC-21) held at Malmö, Sweden last 1-5 July 2019. IVC has an almost 60 years long history of being one of the worlds most recognized conferences and the meeting place where the most recent advances in science and technology are presented and discussed. The conference consisted of plenary lectures, mini-symposia, and a poster session. In the poster session, Kathrina presented her work about Plasma-induced Surface Crosslinking of Chitosan-Acrylic Acid Hydrogel. She synthesized chitosan hydrogel with acrylic acid and ammonium persulfate as the gelling agent and initiator, respectively. Surface cross-linking was induced using an atmospheric pressure plasma.
