Synthesis of Quaternary Ammonium Derivatives of Eugenol and Their Antifungal Mechanism against Wood-Decaying Fungi.

To discover novel preservatives for treating wood-decaying fungi, 48 novel eugenol quaternary ammonium salt derivatives were designed and synthesized. Among them, compounds , , , , , , and showed remarkable antifungal activity against (), affording EC values ranging from 2.11-7.

Mechanoluminescent Aluminum Nitride Crystal for Super-Sensitive Optical Manometry, Thermometry and Force Sensing.

AlN is a core material widely used as a substrate and heat sink in various electronic and optoelectronic devices. Introducing luminescent properties into intrinsic AIN opens new opportunities for next-generation intelligent sensors, self-powered displays, and wearable electronics. In this study, the first evidence is presented of AlN crystals exhibiting satisfactory mechanoluminescence (ML), photoluminescence (PL), and afterglow performance, demonstrating their potential as novel multifunctional optical sensors.

The pleiotropic odorant binding protein CaspOBP12 involved in perception of Ceutorhynchus asper for plant volatiles and pesticides.

The olfactory system of insects plays a vital role in their survival by enabling them to detect chemical cues and adapt to changing environments. The rape stem weevil, Ceutorhynchus asper, is a significant pest posing a challenge for rapeseed production due to its destructive feeding habit and increasing resistance to insecticides. So far, there's still limited knowledge about structure and function of odorant binding proteins (OBPs) in beetles like C.
