Environ Sci Technol 2021 Sep 12. Epub 2021 Sep 12.

Institute of Inorganic Chemistry, RWTH Aachen University, Landoltweg 1a, 52074 Aachen, Germany.

Phosphorus (P) stemming from biodiesel and/or lubricant oil additives is unavoidable in real diesel exhausts and deactivates gradually the Cu-SSZ-13 zeolite catalyst for ammonia-assisted selective catalytic NO reduction (NH-SCR). Here, the deactivation mechanism of Cu-SSZ-13 by P-poisoning was investigated by examination of the structural changes and by probing the dynamics and redox of Cu active sites via a combination of impedance spectroscopy, diffuse reflection infrared Fourier transform spectroscopy, and ultraviolet-visible spectroscopy. We unveiled that strong interactions between Cu and P led to not only a loss of Cu active sites for catalytic turnovers but also a restricted dynamic motion of Cu species during low-temperature NH-SCR catalysis.

Discrimination of Methionine Sulfoxide and Sulfone by Human Neutrophil Elastase.

Molecules 2021 Sep 2;26(17). Epub 2021 Sep 2.

School of Biomedical Science, Faculty of Health, Queensland University of Technology, Brisbane, QLD 4059, Australia.

Human neutrophil elastase (HNE) is a uniquely destructive serine protease with the ability to unleash a wave of proteolytic activity by destroying the inhibitors of other proteases. Although this phenomenon forms an important part of the innate immune response to invading pathogens, it is responsible for the collateral host tissue damage observed in chronic conditions such as chronic obstructive pulmonary disease (COPD), and in more acute disorders such as the lung injuries associated with COVID-19 infection. Previously, a combinatorially selected activity-based probe revealed an unexpected substrate preference for oxidised methionine, which suggests a link to oxidative pathogen clearance by neutrophils.
