Deserts, Rivers, Pools, and Billabongs: Water Features of the Nitrogenase Proteins, and their Functions

open access: yesChemBioChem, EarlyView.
In the protein surrounding the active site of nitrogenase there is a large anhydrous desert, traversed by two watercourses necessary for the enzyme to convert N2 to NH3. Various pools exist, but their water seems to be stagnant. This review examines the occurrence and function of water inside the protein that contains the catalytic site of the enzyme ...

Outcomes of Fluoroscopy‐Based Asymmetric Underexpansion With the Self‐Expanding ACURATE Neo and Neo2 Valve

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Asymmetric underexpansion of transcatheter heart valves (THVs), as observed on fluoroscopy, may influence prosthesis function or long‐term durability of transcatheter aortic valve implantation (TAVI). Aims This study aimed to evaluate the effect of stent frame asymmetry on hemodynamic performance and clinical outcomes in ACURATE neo

Operando UV–Vis Spectroscopy on the Role of Metals in the Methanol‐to‐Hydrocarbons Reaction Zeolite‐Based Catalysts

open access: yesChemCatChem, EarlyView.
Operando UV‐vis spectroscopy is applied to unravel the role of metal‐modified zeolites containing Mg2+, Mn2+, Ca2+ or Zn2+ on the methanol‐to‐hydrocarbons (MTH) reaction. Zeolites ZSM‐5, SSZ‐13 and Beta were modified to assess the universality of the results.
