Dr. Seán Barry is a Professor in the Department of Chemistry at Carleton University. He received his B.Sc. in Chemistry from Queen’s University at Kingston and was awarded his PhD in Inorganic Chemistry from the University of Ottawa. Next, Seán conducted postdoctoral research at the University of Bourgogne in France, Cornell University, and Harvard University. Seán served as a Lecturer at the University of Ottawa and a Visiting Scholar at Harvard University before joining the faculty at Carleton University where he is today. Seán is here with us today to tell us all about his journey through life and science....
Nanovation podcast by Michael Filler interviewing Prof. Stacey Bent from Stanford University. She joins the podcast to talk about Atomic Layer Deposition (ALD), a technique used to modify the composition and properties of surfaces. Since a large fraction of the atoms in nanostructures exist on the surface, ALD has become a quintessential tool for nanotechnologists. In this micro-episode, Stacey explains how ALD got its start, how it works, how the semiconductor industry accelerated its development, and what opportunities lie ahead.
Dr. Tuomo Suntola is a co-owner and Board Member of the Finnish atomic layer deposition technology company Picosun Ltd. He is also Chairman of the Finnish Society for Natural Philosophy, Chairman of the Physics Foundations Society, and author of the books The Short History of Science, The Dynamic Universe, and Theoretical Basis of the Dynamic Universe. He was awarded his M.S. and PhD in electrical engineering from the Helsinki University of Technology where he studied semiconductor physics. Afterwards, Tuomo worked as a Scientist at the VTT Technical Research Centre of Finland for a few years before accepting a position as Chief Scientist at Instrumentarium Ltd. He subsequently served as Director of Display Division and Chief Scientist at the consumer electronics manufacturing company Lohja Ltd, Managing Director of a subsidiary of the national oil company Neste Ltd. called Microchemistry Ltd, a Research Fellow in the national energy company Fortum Corporation. After retiring from Fortum, Tuomo has continued in his roles at Picosun. Over the course of his career, Tuomo has received many awards and honors, including the 2004 European SEMI Award for pioneering atomic layer deposition techniques. He was also honored in 2018 with the Millennium Technology Prize, which is regarded as Finland’s Nobel Prize, for developing this atomic layer deposition technology. He is an elected Member of the Finnish Academy of Technology, was a Member of a World Energy Council working group from 2003-2004, and was named a Knight First Class of the Order of the Lion of Finland. In our interview, Tuomo shared more about his life and science.
In this episode we kick off the ALD series with our first guest, Christophe, coming to speak about in-situ analysis of ALD deposition processes. The different methods (QCM, ellipsometry, Mass spectrometry, IR spectrometry and XPS) are used to probe the film growth and the chemistry of the process happening on the surface and around the deposition chamber. The techniques are presented with some exaples of application at the Coocon lab with a more in depth discussion of the latest research topic of ALD and thin film Li-ion batteries.
Nanovation podcast by Michael Filler interviewing Prof. Greg Parsons. Prof. Greg Parsons from North Carolina State University is the guest on this episode of the Nanovation podcast. Greg is an expert on atomic layer deposition (ALD), the process by which thin films or coatings are deposited atomic layer by atomic layer. Or, as Greg explains, almost. We discuss the good, the bad, and the ugly of ALD. While Greg has explored the use of ALD in a variety of applications, his pioneering work in the area of textiles stands out. Greg's scientific talks are filled with great stories, and this discussion is no different. You’ll hear stories of scientific discovery and also gain insight into Greg’s philosophy for research and life. Be sure to listen to the end to hear Greg participate in the inaugural Nanovation "lightning round."
Nanovation podcast by Michael Filler interviewing Prof. Ruud van Ommen: The ability to coat large quantities of small particles — powders — via atomic layer deposition (ALD) has opened new vistas for battery materials, chemical catalysis, 3-D printing, and more. On this episode of the Nanovation podcast, Ruud van Ommen from TU Delft talks everything powder ALD. In this context, Ruud and Mike focus on the why and how of process scale-up. Listeners of the show won’t be surprised to learn that there’s much more to scale-up than increasing the size of the tank! Ruud also shares the motivation behind founding the company Delft IMP and how, in the early days, he was told that powder ALD was impossible.
Tyler J. Myers from Beneq interviews prof. Michael Nolan of Tyndall Institute Ireland
Episode 13: Becoming Predictive Using ALD Models. In Episode 13, Tyler chats with Michael Nolan from the Tyndall National Institute in Ireland. Michael specializes in molecular and atomistic modeling, using his expertise to help predict, understand, and screen ALD precursors and chemistries. Mike and Tyler talk about all things modeling, including basics for modeling ALD reactions, limitations of current modeling efforts, and how theorists and experimentalists can powerfully work together
Tyler J. Myers from Beneq interviews prof. Riika Puurunen of Aalto University
Back for her second episode, Professor Riikka Puurunen is bringing us back to the basics with a deep dive on conformality. Recorded live from the Harald Herlin Learning Center at Aalto University, Tyler and Riikka talk about the all-important property of ALD. In this episode, Riikka explains the history of conformality in ALD, her recent paper on modeling collaboration, the origins of the PillarHall conformality test structures and a conversation on open science.
