Anthraquinone-based bird repellent for sunflower crops [PDF]

, 2011
Non-lethal alternatives are needed to manage bird damage to confectionery and oilseed sunflower crops (Helianthus annuus). Ring-necked pheasants (Phasianus colchicus) can cause localized damage to newly planted sunflower, and blackbirds (Icterids) damage

Image_3_Influence of Incubation Temperature on 9,10-Anthraquinone-2-Sulfonate (AQS)-Mediated Extracellular Electron Transfer.TIF

, 2019
The electron shuttling process has been recognized as an important microbial respiration process. Because the incubation temperature can influence both the reactivity of electron mediators and cell growth, it may also affect the electron-shuttle-mediated

Synthesis and Optical Properties of Diboron Complexes of 1,4-Anthraquinone Derivatives. [PDF]

Chemistry
1,4‐Diboron complexes exhibit near‐infrared fluorescence, in contrast to non‐emissive 1,5‐diboron analogues. Fluorescence quantum yields decrease with increasing electron‐donating substituents, attributed to enhanced nonradiative decay via intramolecular PeT.
