Intravascular Ultrasound Findings Associated With Hydrodynamic Contrast Recanalization (HDR) of Coronary Chronic Total Occlusions

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Hydrodynamic contrast recanalization (HDR) is a novel technique to facilitate wire crossing during chronic total occlusion (CTO) percutaneous coronary interventions (PCI). The mechanisms underlying HDR have not been fully described.

Integrating Enzymes with Photoredox Catalysis for Conversion of Nitriles into Fluorinated Products

ChemCatChem, EarlyView.
Herein, we describe a novel method for producing highly sought‐after fluorinated compounds through the integration of nitrilase enzymes and iridium photoredox catalysis in a convenient one‐pot reaction. Our chemo‐ biocatalytic methodology delivers a range of fluorinated and fluoroalkylated products from simple nitrile precursors, in good yields, at ...

Sustainable One‐Pot Synthesis of N‐Substituted Pyrroles Using a Multifunctional Cobalt‐Based Catalyst

ChemCatChem, EarlyView.
The one‐pot synthesis of N‐substituted pyrroles from nitrobenzene and 2,5‐hexanodione is first ever reported with >99% conversion and >99% chemoselectivity, in a green solvent, using a non‐noble metal‐based catalyst and hydrogen as a reductant under mild reaction conditions simultaneously.

Application of Metal‐Organic Framework Composites

ChemistryEurope, EarlyView.
This review summarizes the applications of MOF composites in adsorption, energy storage, catalysis, biomedicine, and sensing. It also discusses the functionality of MOF composites from a dimensional perspective. Environmental issues have intensified, and demand for energy continues to grow, making it challenging for conventional materials to meet the ...

Intracellular Catalytic Photooxygenation of α‐Synuclein Amyloid

ChemistryEurope, EarlyView.
Amyloid‐selective catalytic photooxygenation reduces amyloid toxicity, aggregation tendencies, and seeding activities. Achieving therapeutic catalysis for intracellular amyloids is challenging due to conflicting oxygenation and reductive cellular environments.

Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

Chemistry – A European Journal, EarlyView.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.
