Krause writes about Aalto University's new catalysis professor

Professor emerita Outi Krause has written a very nice description related my new affiliation as professor of Catalysis Science and Technology at Aalto University. The text was originally meant for and published in "Katse", the newsletter of the Finnish Catalysis Society. With the permission of prof. em. Krause and the chairman of Finnish Catalysis Society, it is republished in this post in full (in Finnish).

Riikka Puurunen Aalto-yliopiston professoriksi

TkT Riikka Puurunen aloitti helmikuun alussa Aalto-yliopiston kemian tekniikan korkeakoulussa määräaikaisena teknillisen kemian professorina (associate professor) erityisalueenaan katalyysi.

Riikka Puurunen on TKK:n kasvatti. Hän aloitti opintonsa Kemian osastolla vuonna 1994, valmistui DI:ksi neljä ja puoli vuotta myöhemmin ja väitteli tekniikan tohtoriksi vuonna 2002. Jatko-opintoihin sisältyi myös vuoden tutkimusjakso K.U. Leuvenissä Belgiassa. Väitöksen jälkeen hän palasi Belgiaan postdoc-tutkijaksi IMEC-tutkimuskeskukseen. Riikka tuli takaisin Suomeen ja Otaniemeen v. 2004 VTT:lle tutkijaksi, josta hän siirtyi Aalto-yliopistoon. Hän jatkaa myös VTT:n osa-aikaisena vanhempana tutkijana tämä vuoden heinäkuun loppuun asti.

Guest post by Weimer: Early History of Particle ALD at the University of Colorado

Please find below the first guest post ever written for the ALD History Blog: Prof. Alan Weimer from the University of Colorado continues on the topic of a previous related post, sheading light to the early particle ALD developments at the University of Colorado and ALD NanoSolutions.

Early History of Particle ALD at the University of Colorado

In 1997, Steve George and I started investigating the ALD on particles – Steve investigated the surface chemistry through in-situ FTIR and I investigated the processing to coat large volumes of fine particles using a fluidized bed reactor.   At that time, Steve was an ALD chemistry expert and I was expert in the synthesis and functionalization of fine particles, having worked in the area for nearly 20 years.  Much of my background was fluidized processing.  Very intense research that year indicated that we could use ALD to coat large volumes of primary particles identically without “gluing them” to neighboring particles.   HRTEM was key as well as surface area, particle size distribution, FTIR, and XPS measurements; and of course agitated particles.   I was quite surprised that individual primary particles could be coated as I knew that CVD inherently deposited nanoparticles formed in the gas phase, hence, forming agglomerated particles.
