Crystal structure of tris(dimethylamido-κN)bis(dimethylamine-κN)zirconium(IV) iodide

Acta Crystallographica Section E: Crystallographic Communications, 2016
Zirconium amides have become increasingly popular and useful due to their widespread use as precursors to other zirconium complexes and their use in the production of solid oxide fuel cells (SOFCs).

Ab Initio Metadynamics Calculations of Dimethylamine for Probing pKb Variations in Bulk vs. Surface Environments [PDF]

, 2020
The basicity constant, or pKb, is an intrinsic physical property of bases that gives a measure of its proton affinity in macroscopic environments. While the pKb is typically defined in reference to the bulk aqueous phase, several studies have suggested ...

H₂SO₄ and particle production in a photolytic flow reactor: chemical modeling, cluster thermodynamics and contamination issues [PDF]

Atmospheric Chemistry and Physics, 2019
Size distributions of particles formed from sulfuric acid (H2SO4) and water vapor in a photolytic flow reactor (PhoFR) were measured with a nanoparticle mobility sizing system. Experiments with added ammonia and dimethylamine were also performed. H2SO4(g)

Hygroscopicity of nanoparticles produced from homogeneous nucleation in the CLOUD experiments [PDF]

Atmospheric Chemistry and Physics, 2016
Sulfuric acid, amines and oxidized organics have been found to be important compounds in the nucleation and initial growth of atmospheric particles. Because of the challenges involved in determining the chemical composition of objects with very small ...
