报告题目：On the Synthesis and Characterization of Nanomaterials Synthesized over Oxides
报 告 人：Prof. Alicja Bachmatiuk
报告摘要：The catalytic potential of metal catalysts, in particular transition metals, is well known. As a result they are often used very successfully in the synthesis of nanomaterials. For example graphene growth is usually fabricated over copper. However, despite the success of metal catalysts sometimes this can be a disadvantage. For example, when growing graphene over a metal, if it is to be used for device fabrication it needs to be transferred onto an insulator. This transfer process can be damaging. Thus, it might be useful to synthesize such materials directly over oxides. In this presentation I look at a variety of synthesis approaches for 0D, 1D and 2D synthesis over oxides along with their characterization. Structures like graphitic shells (0D), carbon nanotubes/fibers (1D) and graphene (2D) are discussed using synthesis routes such as chemical vapor deposition (CVD) and carbothermal reduction. These structures may have application for electronic, energy and bio-medical applications.
Dr. Alicja Bachmatiuk studied Chemical Technology at Szczecin University of Technology in Poland, where she continued studies for her PhD. She then joined the Leibniz Institute for Solid State and Materials Research, Dresden, Germany as a Marie Curie Fellow and then as an Alexander von Humboldt fellow. She also worked as a manager of electron microscopy laboratories in Wroclaw Research Center in Poland. After that she worked as research professor in the Structural Analysis Group at the Center for Integrated Nanostructure Physics (CINAP), an Institute of Basic Sciences (IBS) in South Korea. Currently, she heads the graphene group at the Laboratory of Carbon and Polymer-Carbon Materials at the Polish Academy of Sciences in Zabrze, Poland.
Her scientific interests include the synthesis, characterization and functionalization of nanomaterials and their application potential. She is also developing in situ Raman spectroscopy and transmission electron microscopy to better understand the synthesis of nanomaterials.
