Photochemistry of Resveratrol: Beyond the Reactivity of Metal‐Free Porphyrins Immobilized on Lignin

ChemPhotoChem, EarlyView.
Resveratrol photochemistry with singlet oxygen is examined at 450 nm using blue‐LED irradiation and various homogeneous and heterogeneous photosensitizers. Products of CC bond cleavage, electrocyclic ring closure, and [4 + 2] cycloaddition are identified.

Rational Design of a Perovskite‐Type Catalyst for Toluene Oxidation Via Simultaneous Phosphorus Doping and Post‐Synthesis Acidic Etching

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Phosphorus doping in the perovskite oxide LaCoO3‐δ (LC) results in the formation of LaCo0.97P0.03O3‐δ(LCP3), which is further modified through post‐synthesis acidic etching, yielding LCP3‐A. Phosphorus doping in LCP3‐A enhances its durability, particularly improving long‐term durability and tolerance to H2O and CO2 during toluene oxidation, while acid ...

Effects of geranylgeranylacetone on diastolic and microvascular function in patients with heart failure with a preserved ejection fraction: A phase 2, randomized, placebo‐controlled, crossover trial

European Journal of Heart Failure, EarlyView.
Abstract Aims Heart failure with preserved ejection fraction (HFpEF) is a major healthcare burden with limited treatment options. Geranylgeranylacetone (GGA) has been shown to improve myocardial compliance and endothelial function in preclinical models.
