In Situ Reaction Mechanism Studies on Lithium Hexadimethyldisilazide and Ozone Atomic Layer Deposition Process for Lithium Silicate

Autor: Mikko Ritala, Markku R. Sundberg, Markku Leskelä, Kjell Knapas, Yoann Tomczak

Publikováno v: The Journal of Physical Chemistry C. 117:14241-14246

Reaction mechanisms in the LiN[Si(CH3)3]2–O3 atomic layer deposition (ALD) process for lithium silicate were investigated in situ with a quartz crystal microbalance (QCM) and a quadrupole mass spectrometer (QMS) at several temperatures. In addition

Bismuth(III ) Alkoxide Catalysts for Ring-Opening Polymerization of Lactides and ϵ-Caprolactone

Autor: Sirpa Vuorinen, Mohammed Lahcini, Timo Hatanpää, Markku R. Sundberg, Markku Leskelä, Timo Repo

Publikováno v: Macromolecular Chemistry and Physics. 214:707-715

Homoleptic bismuth alkoxide complexes, Bi(OR) 3 [R = i Pr (1), t Bu (2), and CMe 2 i Pr (3)], are used as catalysts in the ring-opening polymerization (ROP) of lactides. In contrast to 1, two bulkier bismuth alkoxides, 2 and 3, show high activity in

In Situ Reaction Mechanism Studies on the New tBuN=M(NEt2)3 -Water and tBuN=M(NEt2)3 - Ozone (M = Nb,Ta) Atomic Layer Deposition Processes

Autor: Kjell Knapas, Yoann Tomczak, Markku R. Sundberg, Markku Leskelä, Mikko Ritala

Publikováno v: Chemistry of Materials. 24:1555-1561

In this work, quartz crystal microbalance (QCM) and quadrupole mass spectrometry (QMS) have been used for in situ investigations of the D2O and ozone processes at 250 °C for tBuN=Nb(NEt2)3 and tBuN=Ta(NEt2)3. In the D2O processes, the ligand exchang

Conformational diversity of dichromate dianion

Autor: Rolf Uggla, J. Valo, Markku R. Sundberg, Milan Melnik

Publikováno v: Inorganica Chimica Acta. 383:164-168

The available experimental structures containing a dichromate dianion were gathered from the ICSD (Inorganic Crystal Structure Database) and CSD (Cambridge Structural Database) databases. The geometrical parameters show considerably wide range in bon

Analysis of crystallographic and structural data of polymeric iron-alkaline metal complexes

Autor: Rolf Uggla, Markku R. Sundberg, Milan Melnik

Publikováno v: Main Group Metal Chemistry, Vol 34, Iss 5-6, Pp 93-126 (2011)

The present review covers almost 100 polymeric MFe (M=Li, Na, K, Rb, and Cs) compounds. The metal atoms of group 1 as partners with iron atom build up complex polymeric chains. The iron atoms are found in the oxidation states 0, +2, and +3, of which
