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

[post is a duplicate from the Catalysis Professor's Open blog by the same author:]

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, direct link (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 (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.

ALD Russia 2021: VPHA presentation

On October 27-30, 2021, the ALD Russia 2021 workshop was organized (, chairperson: Prof. Anatolii Malygin). 

This was the third time that an event in this series was organized. The blog author (Puurunen) had the honor of attending the first event in Moscow 2015. From there, travel notes were published in the BALD Engineering blog here, and in and updated form (e.g. photos added) in the in-the-meantime-created ALD History Blog here.  

This time, the event was organized in a light hybrid way, enabling the giving and following of presentations via Zoom. This approach enabled some international guests to participate despite the Covid-19 pandemic. Among such visitors, was the author of this blog. Interestingly, many presentations have their slides shared on the website, see

As one of the Zoom-based talks, there was a presentation related to the Virtual Project on the History of ALD (VPHA):
  • R. L. Puurunen, Yu. Koshtyal, J. Sundqvist, J. R. van Ommen, O. Yurkevich, Virtual Project on the History of ALD in perspective: past, present, and final steps (slides, video, abstract).
In the presentation, the message was shared that the core activity of VPHA, reading and writing short comments on early ALD works to share, will be activated again. Preliminarily planned timing is to start in November 2021. Everyone with interest in ALD and its history is welcome to join - contact info @ if you wish to join as a new contributor. More info to come!
