《化工学术大讲堂》系列高端学术报告 (第 三十三 期) Scalable manufacturing of nanostructured materials by atomic layer deposition in fluidized bed reactors 主讲专家 J. Ruud van Ommen 教授 Delft University of Technology 荷兰代尔夫特理工大学 报告时间及地点 2017年5月18日星期四上午10:00 四川大学望江校区化学工程学院313报告厅 专家简介 J. Ruud van Ommen received his MSc (1996) and PhD (2001) in Chemical Engineering, both at Delft University of Technology (the Netherlands); he was appointed as assistant professor at Delft afterwards. He has been visiting professor at Chalmers University, Sweden (2004–2005), and the University of Colorado at Boulder, USA (2009). Since 2016, he is full professor in Delft, working on solids processing and chemical reaction engineering, with a focus on scalable manufacturing of nanostructured materials. He has been the recipient of the prestigious VENI (2005), ERC Starting (2011), and ERC Proof of Concept (2013 & 2015) grants. He recently co-founded the spin-off Delft IMP. International activities Co‐chair of the BRG 23th International Conference of Bioencapsulation (Delft, Sept. 2015). Co‐chair of the 14th International Conference on Fluidization (Noordwijkerhout, 2013). Session organizer of multiple sessions during the AIChE Annual Meeting (since 2009, ongoing). Member of the advisory board of the tri‐annual Conference on Fluidized Bed Technology (ongoing). Member of the editorial boards of the International Journal of Chemical Reactor Engineering and Chem Engineering. 原子层沉积机理图 Schematic representation of Al2O3 ALD based on trimethylaluminum (TMA) and H2O: (a) exposure of the substrate surface to TMA and reactions between TMA and surface active sites (e.g., –OH and oxygen bridges); (b) purging of excess TMA and reaction by-product (i.e., CH4); (c) exposure of the substrate surface to H2O and reaction between H2O and precursor ligands; (d) purging of excess H2O and reaction by-product (i.e., CH4); the four steps (a) to (d) compose one ALD cycle.
