On Metal Carbonyl Compounds in Catalytic Methanol Synthesis: Detection, Consequences, and Removal
Chemie Ingenieur Technik, EarlyView.Deactivation of Cu/ZnO/Al2O3 catalysts by metal carbonyl compounds in the feed gas is a critical problem in catalytic methanol synthesis. We utilize PTR–MS to identify potential chemical sources, detect contamination in an in‐house CO gas line, and validate filter methods for removing these catalyst poisons before synthesis.

The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces
Geophysical Monograph Series, Page 229-246., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.
