Happy 45th anniversary, ALD in Finland - Aalto ALD OpenLearning platform opens

Exactly forty-five years ago, on November 29, 1974, the first patent on Atomic Layer Epitaxy (FIN 52359) was filed by Suntola and Antson.

Five years ago, the same day, materials of the exhibition materials of the "40 Years of ALD in Finland - Photos, Stories" (#FinALD40) were released for public; they are still accessible via the ALDCoE website and the VPHA website.

Today, the Aalto ALD OpenLearning site is opened for public. You can access it via the general link and the direct link

Also today, at Aalto University an event is organized: November Networking - ALD at Aalto University event. We have 63 participants registered, webpage

Happy 45th anniversary, atomic layer deposition (ALD) in Finland!

Subject: VPHA status update 7.11.2019: November Networking ... and request to recommend ALD reviews

Dear VPHA contributors and prospective contributors,

With this email, I would like to update you recent progress around the interest area of the Virtual Project on the History of ALD (VPHA) since the previous VPHA status update on July 9.

1. “November Networking – ALD at Aalto University”. This is an event to be organized at Aalto University on November 29 afternoon, open for anyone to attend. In addition to local presentations and posters, there will be an international invited talk (Prof. Ruud van Ommen). If someone from the VPHA collaborators is interested to participate, you are most welcome to do so; poster presentation slots are still available (re-registration needed), and one can also come to network without any presentation. More info of the event and links below.

2. Request to recommend review articles on ALD. Along with November Networking – ALD at Aalto University (29.11.2019), the plan is to open an Aalto OpenLearning site related to Atomic Layer deposition, aimed to benefit the global ALD community. The site will start with small initially, mainly linking to existing contents, with the purpose to expand later in contents. The first original item to be created is a listing of recommended reviews on ALD.

To build a balanced, justified recommended reading list for ALD reviews, I welcome all VPHA contributors and prospective contributors (and others as well!) to write and share recommendations for their favourite ALD review(s) in recommended-ALD-reviews-evolving-file (it is a Google Docs file). More information in the blog post:, reposted from Catalysis Professor’s Open.

Advance info on OpenLearning site on Atomic Layer Deposition + request to recommend ALD reviews

Advance info: On Nov 29, 2019, a new OpenLearning site is planned to open on atomic layer deposition (ALD) at the platform. The site is meant to benefit the global ALD community and operate mostly in English; occasionally, the site may link to ALD learning materials on other languages. The site will grow with time and initially mainly link to contents that are already openly existing. 
Among the materials to be created for the site is a (living) list of recommended reviews. According to the list created in the Virtual Project on the History of ALD (VPHA,*), link here (which continues lists published in 2005 in and in 2013 in, over 200 reviews on ALD have been published. Two hundred reviews is obviously too many for any individual to read. A shorter list would be meaningful, skill keeping the full list easily accessible. 
I welcome anyone globally, who sees the value of the initiative to field, to help build a list of recommended reviews. Please recommend reviews that you think would be useful to include, and provide a brief justification with your recommendation in your own words. Please recommend only reviews authored by others than yourself or your close relatives.** All recommendations are to be collected together in one place called recommended-ALD-reviews-evolving-file (it is a Google Docs file). This file will be a living document and have © Authors (all rights reserved); it thus NOT allowed to copy contents to third-party sites without explicit permission by the respective authors***. 
The open learning site on ALD and recommended review list are both new initiatives. Hopefully the new learning site and materials can complement (not replace!) existing teaching materials and efforts and thereby help newcomers to enter the field of research and development in ALD.
