New Zenodo community! ALD saturation profile open data. Ideas? Questions?

7.08.2020

Yesterday, I created a new Zenodo community: “ALD saturation profile open data”, https://zenodo.org/communities/ald-saturation-profile-open-data/. In my research group, we intend to use this first for sharing experimental saturation profile data related to a publication we are writing (access through the ChemRxiv, https://doi.org/10.26434/chemrxiv.12366623).

Before we are so far that we can actually deposit open data there, we know that there are many things to solve. I anticipate also that we will run into new questions, of which we were not aware yet.

I understand that others may have interest also for this open science community. It came to mind, that now could be a good time to do some collective thinking on how to progress. To do so, I created an open file Google Docs file, to collect ideas and questions by different people together.

Below you find the text I wrote for the document (introductory part). read more >>

Virtual guest speaker with Bent group Stanford – other groups interested in an ALD fundamentals talk?

23.07.2020

Yesterday, I participated a Prof. Bent group meeting (Stanford), giving again the presentation we gave jointly with Prof. Ruud van Ommen at the recent ALD conference (see previous post), entitled “On the fundamentals of ALD: the importance of getting the picture right”.

It was a pleasure and honor for me to be invited as a virtual guest speaker in the Bent group. Nice, lively and useful discussion on the fundamentals of ALD followed — thank you very much for everyone who was present! Special thanks to Josiah Yarbrough who invited me in the first place.

The discussion was so useful that it came to my mind: I could do this again. Would some other group in the world wish to have a similar “virtual ALD fundamentals visit” from me (or perhaps from Ruud van Ommen)? I’d be happy to meet e.g. via Zoom.  read more >>

“On the fundamentals of ALD: the importance of getting the picture right” – by Puurunen and van Ommen

5.07.2020

Jointly with Prof. Ruud van Ommen, I (Prof. Riikka Puurunen) gave a presentation at the AVS 20th International Conference on Atomic Layer Deposition (ALD 2020) featuring the 7th International Atomic Layer Etching Workshop (ALE 2020), adapted into a Virtual Meeting, Jun 29 – Jul 1, 2020, https://ald2020.avs.org, aimed to initiate/contribute to discussion of the fundamentals in the field of atomic layer deposition (ALD).

Please find the abstract of the presentation in this blog post, below. Once the slides and video record of the talk are openly available, the purpose is to link them to this post, too.

Title: On the fundamentals of ALD: the importance of getting the picture right 
Authors: Riikka L. Puurunen and J. Ruud van Ommen
Session: Precursors and Chemistry: Simulation, Modeling, and Theory of ALD

Abstract Text:
Atomic layer deposition (ALD) has become of global importance as a fundamental building block for example in semiconductor device fabrication, and also gained more visibility (e.g., the Millennium Technology Prize 2018). In recent years, the number of ALD processes has increased, new groups have entered the field, and fundamental insights have been gained. At the same time, significantly varying views exist in the field related to the description and meaningfulness of some core ALD concepts. Open, respectful but critical scientific discussion would be needed around these concepts – for example at this AVS ALD/ALE conference, the world’s largest conference on ALD. read more >>

Three years as a tenure track professor at Aalto University

3.02.2020

Three years ago, I started at Aalto University as professor (associate professor, catalysis science and technology). I started in February 2017, and worked 60% of time for the first half year, being at my former employer VTT for 40%.

In this post, I look back at my three first years as a professor and try to create an overview of the most important things that have taken place. When I had been at Aalto University of one year, I wrote a similar blog post, reflecting on the status then; those who are interested, can access it here.

The past three years have been years of continuous change. After three years, change seems only to continue. I look to the future with an optimistic mindset, advocating (also with this publication) what has in essence become my motto: “more openness in science and education”. Fits nicely in Aalto University’s new strategy, too.

— Puurunen’s three-year professor summary begins —

Among the most important tasks of a professor is – to acquire research funding. Without funding, one cannot hire people to work in the group, and little progress can happen. That professors acquire competed funding is not only important for the functioning one’s own group but for the whole university, as overheads of the projects help pay university-level costs. Most funding applications do not get funded – depending on the call, even less than 10% of applications may get funded.

My major funding applications of three years in a nutshell: read more >>

Season’s greetings and Happy 2020 from Aalto Catalysis group

19.12.2019

Dear colleagues, collaborators, emeriti, old and potential future colleagues and collaborators,

Year 2019 approaches its end, and it is a good time to look back on the activities of the Aalto Catalysis group in the past year.

A slogan for the undersigned and the Catalysis group this year has been “more openness in science and teaching”. The quest for more openness resulted in a nice recognition with Aalto CHEM’s award Educational action of the year 2019 for online lecture recordings. There is more on the justification (directly by students!), background and extended thanks related to the recognition in a recent blog post in Catalysis Professor’s Open: https://blogs.aalto.fi/catprofopen/2019/12/13/online-lecture-recordings-are-educational-action-of-the-year-2019-aalto-chem/.  We will continue to work for more openness in science and teaching in 2020.

Publication-wise, year 2019 has been nice for the group. read more >>

Online lecture recordings awarded as Educational action of the year 2019, Aalto CHEM

13.12.2019

On December 12, at Dean’s Glögg event, several recognitions were shared at Aalto University School of Chemical Engineering (Aalto CHEM). I (Riikka Puurunen) was among the happy ones to receive a recognition this year – together with Lauri Partanen – for the use of online lecture recordings in education.

The grounds for the recognition were as follows:

Teaching act of the year 2019

Grounds and reasoning for award from students:

Digitalisation is continuously discussed as bring of ever-increasing importance, and this also applies to the field of education. With complex topics, it is vital that students are able to study lecture material at their own pace as many times as needed. Additionally, the ability to miss lectures when sick or otherwise occupied helps to reduce stress related to studies and ultimately to achieve a successful course. Therefore, on behalf of students, we would like to nominate “online lecture recordings” as Teaching Action of the Year. This includes a special mention to both Riikka Puurunen and Lauri Partanen, who have respectively championed in their Master’s and Bachelor’s courses with high quality online record lecture material.

  • Prof. Puurunen uses and actively tries out new methods in her teaching. Examples about this are lecture recordings made with Panopto, which enable (re)doing the lectures afterwards. In addition to this, on her MSc Catalysis course she did a video of the derivation of Langmuir isotherm with the “digital chalkboard” lightboard. The teaching material is also openly shared via a blog and a YouTube channel.
  • Lauri Partanen has used many digital teaching methods on his course “Kemiallinen termodynamiikka”. He has added video recordings of his teaching sessions made with Panopto. He has used online quiz questions during his teaching sessions to support learning. He has also created a Telegram group, where students can ask him questions related to the course and give feedback. Getting feedback in this quick and easy way has allowed him to make changes already during the course.

Related Aalto CHEM news item: https://www.aalto.fi/en/news/teaching-achievement-of-the-year-awarded-to-lecture-recordings.

In the description, students referred to the MSc Catalysis course, a blog, and to a Youtube channel. Here, I want to tell a bit more of each item.

Panopto records: November Networking – ALD at Aalto University

12.12.2019

At the “November Networking – ALD at Aalto University” event on November 29, 2019, we experimented with recording (some of the) talks with the Panopto lecture capture system available at Aalto University.

The records have now been finalized. Each author who participated in the Panopto recording was sent a link to check. Most were authors were fine with sharing. Some decided to decline, after all, and some have not answered the request (DL was December 10).

In the next table, the Panopto captures are shared for those talks, for which a permission to share has been confirmed. This recording was an experiment and done for the first time, and not all records are of fully satisfying voice quality (e.g. #3, unfortunately). Nevertheless, the records are shared, as we can learn most, also of quality issues, by having the examples available. Enjoy!
