Season’s Greetings from the Aalto Catalysis group

[distributed also via email by RLP]

Dear past, present and potential future colleagues and collaborators; dear friends:

 

Another year is over, and it is good to take a moment to look back.

 

In 2021 – my fifth year as a professor at Aalto University – a lot of experimental progress took place in all three projects of the Catalysis group (HDN catalysis project funded by Neste & COOLCAT and ALDI projects funded by the Academy of Finland). While this progress is not yet seen in our publications (2021 list at the end of the email), some of our activities can be seen in an introductory video we made of the COOLCAT project – turned out quite nice!

 

There are some particular advances related to teaching, research, events and theses I would like to recap from 2021.

 

As for teaching in 2021:

  • Scientific Article Exercise (SAE) was carried out for the first time with all first-year M.Sc. students of School of Chemical Engineering. SAE is a new module which I have been developing, with the goal that students better understand the fundamental differences between scientific articles and e.g. webpages.
  • A new type of co-creation group work was experimented with in the CHEM-E1130 Catalysis course (theme: methanol economy). This received overall positive feedback from students and will be a clear “keeper” (next theme: hydrogen economy).
  • A new concept was tried related to individual research projects for students (10 ECTS). Attention was given e.g. to report writing and feedback in several steps. The overall concept seemed to work and this seems as a “keeper”, too.

 

As for research in 2021:

  • After years of aiming for it, the first open data set related to our research has been published: https://zenodo.org/record/3974438#.Yb7Xo71BxQI.
  • The Kirk-Othmer Encyclopedia of Chemical Technology (finally!) has a chapter on atomic layer deposition (ALD), https://doi.org/10.1002/0471238961.koe00059, which I had the honor to co-author with researchers from TU Delft. Notably, many new illustrations were created, separately published with a Creative Commons license for easy reuse. Images in Wikimedia Commons (category: atomic layer deposition), and one in Zenodo.org.
  • I gave an introductory “ALD 101” tutorial on the fundamentals of ALD at the international AVS ALD conference. Tutorial available e.g. in Youtube.

 

As for event organization:

 

As for theses in 2021, two doctoral theses were successfully defended (Irene Coronado and Eveliina Mäkelä) and four Master’s thesis were finalized (list here).

 

In 2021, was also granted tenure at Aalto University: I will be happy and honoured to continue contributing to Aalto’s success in the coming years.

 

With this letter, and the Aalto card, I wish everyone a happy Christmas time and all the best for the year 2022.

New Podcasts section in ALD OpenLearning site (Nov 20, 2021)

Yesterday (Nov 20, 2021), a new section was published in the OpenLearning site on atomic layer deposition  (ALD). The site is available at the OpenLearning platform of Aalto University https://openlearning.aalto.fi/, direct link https://openlearning.aalto.fi/course/view.php?id=100 (can be found by searching for “ALD” or “atomic layer deposition”).

The Podcasts section contains each podcast (that the author of this blog and the author/curator of the ALD OpenLearning site currently is aware of) as a separate “page” (as in defined the Moodle platform). Currently, the following podcasts have their own page: ALD Stories by Beneq, Nanovation, STG podcasts, Suomalaisten Kemistien Seura (a Finnish society), People Behind the Science and ALD Pulse.

In each page, named according to the specific podcast, direct links have been included to ALD-related episodes, which were available at the time of opening the Podcasts section (Nov 20, 2021). Most podcasts are in English. One podcasts in Finnish has also been linked to, and in the future more links to podcasts in other languages than English can also be included. The episodes in English contain interviews of many ALD scientists, including such internationally known names like Dr. Tuomo Suntola (the Finnish inventor of ALD), Prof. Seán Barry, Prof. Stacey Bent, Prof. Erwin Kessels, Prof. Mikko Ritala, Dr. Jonas Sundqvist, Prof. Ruud van Ommen and Prof. Charles Winter (list in alphabetical order, except for Suntola). The author of this blog (Prof. Riikka Puurunen) also had the honor of being interviewed for the ALD Stories podcast by Beneq (related to the history of ALD).

If some podcast or episode is missing from the list, I will be happy to add it. Please let me know of missing items — email to firstname.lastname@aalto.fi (replace with my info) should work well. Also, if someone would *not* like to have their podcast/episode included in this collection, it can be removed — please in such case contact me as well.

Poster DL postponed: 2021 November Networking — ALD at Aalto University

Already about seventy persons registered to participate at 2021 November Networking — ALD at Aalto University!

The original deadline (DL) for registering with poster presentations was last Sunday. However, there is still space for more posters, and with the light organization that we have, we realized that we can take in registrations with the same schedule as other in-person registrations. So, we decided to postpone the DL.

Updated registration DLs according to type of participation:

  • Local in-person participation (with or without poster): registration DL Mon 22.11.2021. The number of posters may need to be limited; “first come, first serve”.
  • Zoom participation: registration DL Wed 24.11.2021. The number of participants might need to be limited (but likely not); if limiting is needed, “first come, first serve”.

Save the date: November Networking – ALD at Aalto University, 26.11.2021

November Networking – ALD at Aalto University will be organized again! This time, on Friday 26.11.2021, at 13 on, at Aalto University School of Chemical Engineering (lecture hall Ke 2).

The decision to organize the event was made just a few days ago. At the moment, the organizing committee is formed by myself (Riikka Puurunen) and a postdoc in my group, Jorge Velasco. Programme is still under planning. Expect at least:

  • Posters by researchers. Not online as in the 2020 event, but in person! We have the downstairs lobby reserved for this — just like in the 2019 event.
  • Presentation on recent (1) book and (2) encyclopedia chapter on ALD. (1) Prof. Sean Barry (Carleton University, Canada) has published (/will publish: the book is not quite yet out! see: https://www.degruyter.com/document/isbn/9783110712513/html) a book on ALD chemistry; and (2) Prof. Ruud van Ommen (TU Delft, The Netherlands) has published (with A. Goulas and R.L. Puurunen) an introductory chapter on ALD for the Kirk-Othmer Encyclopedia of Chemical Techonology (https://doi.org/10.1002/0471238961.koe00059). Both Barry and van Ommen plan to be present at the event in person!
  • Discussion on the history of ALD and on the next steps in the VPHA project. The third coordinated reading effort in the Virtual Project on the History of ALD (VPHA, http://vph-ald.com) is about to start. Everyone interested in understanding the early history of ALD is welcome to join this open science type effort. A recent presentation on the VPHA in perspective here: https://youtu.be/7p8-pB7wsm8 (abstract and slides available via: https://vph-ald.com/ALD-history-publications.html).

Zoom-breakout-room-based online poster session: how did the second trial go?

In the previous post, I reported on the feedback that we received for the first-ever online poster session that we organized, using Zoom and the breakout rooms as basis. This was in November 2020 (2020 November Networking – ALD at Aalto University).

Feedback from the November 2020 online poster session was encouraging: clearly the concept can be repeated, and also improved. Soon, (as an already-experienced person,) I was requested to organize another online poster session: in April 2021 for the Finnish Young Scientist Forum on Catalysis (FYSFC 2021). With help from my group, we tweaked the earlier instructions and organization a little. Main change was that we gave more time for the presentations: instead of starting a new presentation every 5 min like in the first event, we started with a new presentation every 10 min.

Again, we collected feedback of the online poster event; this feedback is shared below. I interpret that:

  • Zoom breakout rooms are a meaningful way to organize an online poster session
  • 10 min for poster presentation slot can be ok. The feeling was less hasty than from 5 min presentations, and this is also seen from the feedback (absence of complaints of too short slots — even a request to have still longer time reserved).

Would I be willing to organize a Zoom-breakout-room-based online poster session again in the future? Sure! Two rounds of practice has taught how to organize one (good pre-planning is a must!). Also, I have seen how this type of an online poster session can be a meaningful way network remotely, when we cannot meet in person. A further benefit is that as university teaching staff, we have this tool at hand, and we don’t need to spend time (or money) on learning new systems. We can use the tools we are used to — just in a bit a new way.
