The phytopathogenic fungi and infect different crop plants. Essential oils have been used as an alternative to chemical control methods. Therefore, the objective of this study was to analyze the essential oil chemical composition of the stem bark of (ZREO) and evaluate its antifungal potential. The ZREO obtained by hydrodistillation was analyzed using gas chromatography coupled to mass spectrometry and evaluated for antifungal activity. The major components identified in the chemical analysis were -nerolidol (67.21%), α-selinene (14.94%), and β-selinene (7.41%). The antifungal potential of ZREO against and was detected at all concentrations evaluated in a dose-dependent manner. The best results were against , with the concentration of 150 µLmL inhibiting more than 80% of mycelial growth. On the basis of the current knowledge, this study describes for the first time the chemical composition and their antifungal activity.

An N,N,N-type Cu(Ⅱ) complex-catalyzed desaturation method for converting alcohols, ketones, lactones, and lactams to their α,β-unsaturated carbonyl compounds is reported. The dehydrogenation reaction can be conducted with a green terminal oxidant O2 without requiring strong acid/base or stoichiometric oxidants. The Cu(Ⅱ) complex/TEMPO/O2 system uses a non-noble catalyst, and a green terminal oxidant as well as demonstrates high activity and functional group tolerance.

Monitoring wound infection and providing appropriate treatment are crucial for achieving favorable outcomes. However, the time-consuming nature of laboratory culture tests may delay timely intervention. To tackle this challenge, a simple yet effective HDG hydrogel, composed of hydrogen peroxide (H₂O₂), dopamine, and GelMA polymer, is developed for the ultrafast detection and treatment of Staphylococcus aureus (SA) infections.

Moth-eye nanostructures, known for their biological antireflective properties, are formed by a self-assembly mechanism. Understanding and replicating this mechanism on artificial surfaces open avenues for the engineering of bioinspired multifunctional nanomaterials. Analysis of corneal nanocoatings from butterflies of the genus reveals a variety of nanostructures with uniformly strong antiwetting properties accompanied by varying antireflective functionalities.

Piezoelectric materials directly convert between electrical and mechanical energies. They are used as transducers in applications such as nano-positioning and ultrasound imaging. Improving the properties of these devices requires piezoelectric materials capable of delivering a large longitudinal strain on the application of an electric field.
