Phenolic Profiling of Olive (Olea europaea L. cv. Nocellara Messinese) Samples by Comprehensive 2D Liquid Chromatography

open access: yesChemFoodChem, EarlyView.
Comprehensive RP‐LC×RP‐LC‐PDA‐MS/MS profiling reveals 52 phenolic compounds across olive drupes, leaves, pomace, and extra virgin olive oil, highlighting matrix‐specific distribution patterns. Oleuropein derivatives dominate drupes, while flavonoids are enriched in leaves.

Twisted 1‐ and 2‐Azaperopyrenes: Synthesis, Structure, and Properties

open access: yesChemistry – A European Journal, EarlyView.
ABSTRACT A synthesis of hitherto unknown 1‐ and 2‐azaperopyrenes, twisted nitrogen‐doped peropyrenes, is reported. The synthesis is based on a Brønsted acid‐mediated benzannulation of alkynes. Key alkyne intermediates are synthesized via two complementary routes, including a Pd/C‐catalyzed, copper‐ and amine‐free Sonogashira‐type coupling of (hetero ...

Bifunctional Molecular Switches in Fused Diarylethene–Rhodamine Systems

open access: yesChemPhotoChem, EarlyView.
Spectroscopic and time‐dependent density‐functional theory studies show that these novel rhodamine‐based diarylethene (DAE) compounds display intense UV absorption, undergo reversible two‐step protonation involving triazole and rhodamine units, and respond selectively to acid, base, and metal ions.

Stabilizing Layered LiCoO2 Cathode in Aqueous Electrolytes through a Surface‐to‐Bulk Niobium Modification

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A surface‐to‐bulk niobium modification strategy is developed for LiCoO2 (LCO) cathode in aqueous lithium‐ion batteries (ALIBs). Benefiting from the synergistic effect of LiNbO3 (LNO) surface coating and Nb gradient doping, interfacial side reactions and irreversible phase transformations (from layered‐to‐spinel phases) are effectively suppressed ...

Fast cycle of vagus nerve stimulation is associated with increased sleep‐related breathing disorder in patients with epilepsy

open access: yesEpilepsia, EarlyView.
Abstract Objective This work was undertaken to study the association between vagus nerve stimulation (VNS) parameters and the apnea–hypopnea index (AHI) measured by polysomnography in patients with drug‐resistant epilepsy. Methods Patients with epilepsy who underwent polysomnography with an active VNS device between 2018 and 2023 were retrospectively ...
