Assessment of antimicrobial and anti-biofilm activities of lemongrass and bay leaf extracts on microorganisms from fermented cereal-based porridges in northern Benin

Scientific African
Lemongrass (Cymbopogon citratus) and bay leaf (Laurus nobilis) are condiments in food processing. This study aimed to assess the antimicrobial and anti-biofilm activities of lemongrass and bay leaf extract on the microorganisms isolated from cereal-based

Synthesis and Structure of an S‐Shaped Double Expanded Helicene With Seven Fused Anthracene Units

Chemistry – A European Journal, EarlyView.
The anthracene‐fused aromatic compound was synthesized by four‐fold cycloisomerization of the corresponding alkyne precursor. X‐ray crystallographic analysis revealed that this compound had a double helical structure of Ci symmetry, in which the terminal and central anthracene units were triply stacked.

The Electronic Spin State of Diradicals Obtained from the Nuclear Perspective: The Strange Case of Chichibabin Radicals

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
The electronic spin state of two Chichibabin radicals is investigated using 2‐dimensional hyperfine correlated Electron Nuclear Double Resonance. The protons (I=1/2) act as a reference for the electronic spin quantum number (S) via their hyperfine interactions.

Meso-Disubstituted Anthracenes with Fluorine-Containing Groups: Synthesis, Light-Emitting Characteristics, and Photostability

, 2016
Synthesis, photophysical properties, and photostability of 9,10-disubstituted anthracenes with fluorine-containing groups (FCG) are described. The values of Φf and λem greatly go up by the meso-substitution with FCG, and a nice corelationship between Φf ...

Charge State Influence on Stability and Isomerism in Dehydrogenated PAHs: Insights from Anthracene, Acridine, and Phenazine

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
The ionization of anthracene, acridine, and phenazine has been explored, along with the removal of one and two hydrogen atoms, to provide valuable information for astrochemists and to understand the behavior of the resulting structures and their electronic reorganization. Abstract In this study, we systematically explored the stability and isomerism of
