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

Revisiting the Reaction Mechanism of Electrochemical 1,4‐NADH Regeneration on Carbon Electrodes

open access: yesChemCatChem, EarlyView.
The mechanism of NAD+ electrochemical reduction on carbon‐based electrodes varies with the applied potential. Catalyst loading, buffer, and initial NAD+ concentration can be optimized to achieve the highest 1,4‐NADH selectivity. Abstract The direct electrochemical regeneration of 1,4‐NADH, an essential cofactor in many enzymatic reactions, has emerged ...

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.
