Cooperative Redox Catalysis of N2O Decomposition by Short‐Range RhOx and CeOx Anchored to Co3O4

Angewandte Chemie International Edition, EarlyView.
A short‐range Rh–O–Co–O–Ce interfacial moiety drives low‐temperature N2O decomposition via a cooperative redox cycle. Operando modulated‐excitation XAS with phase‐sensitive detection (ME‐XAS + PSD) tracks rapid, reversible Rh oxidation coupled to Co reduction.

d-Amino acids differentially trigger an inflammatory environment in vitro

Amino Acids
Studies in vivo have demonstrated that the accumulation of d-amino acids (d-AAs) is associated with age-related diseases and increased immune activation. However, the underlying mechanism(s) of these observations are not well defined. The metabolism of d-

A comparison of ceria and Sm-doped ceria for hydrocarbon oxidation reactions

Applied Catalysis A: General, 2004
Abstract The oxidation of methane, ethane, propane, and n -butane has been studied over CeO 2 and Samaria-doped ceria (SDC) catalysts. The rates for methane and ethane were found to be indistinguishable over the two catalysts, while the rates for propane and n -butane were much higher on ceria compared to SDC.
