Background & Objective: Nanoparticles are used in cosmetic and dermatologic products, due to better skin penetration properties. Incorporation of natural products exhibiting medicinal properties in nano-preparations could significantly improve the efficacy of these products and improve the quality of life without the side effects of synthetic formulations.
Methods: We here report the green synthesis of Copper Oxide nanoparticles, using Cucumber extract, and their detailed bio-physical and bio-chemical characterization.
Results: These Copper Oxide-Cucumber nanoparticles exhibit significant anti-bacterial and anti-fungal properties, Ultra Violet-radiation protection ability and reactive-oxygen species inhibition properties. Importantly, these nanoparticles do not exhibit significant cellular toxicity and, when incorporated in skin cream, exhibit skin rejuvenating properties.
Conclusion: Our findings have implications for nanoparticle-based cosmetics and dermatologic applications.

Insect metamorphosis is a complex developmental process regulated by microRNAs (miRNAs) and hormonal signaling pathways. Key genes driving insect ontogenic changes are precisely modulated by miRNAs, which interact with 20-hydroxyecdysone (20E) and juvenile hormone (JH) to coordinate developmental transitions. Over the past decade, significant progress has been made in understanding miRNA biogenesis, their regulatory roles in gene expression, and their involvement in critical biological processes, including metamorphosis and chitin metabolism.

Electrocatalytic hydrogenation (ECH) of quinoline provides an eco-friendly and prospective route to achieve the highly value-added generation of 1,2,3,4-tetrahydroquinoline (THQ). Co element has been proven to be the efficient catalytic site for ECH of quinoline, but the rational regulation of the electronic structure of active Co site to improve the activity is still a challenge. Herein, the hierarchical core-shell structure consisting of NiCo-MOF nanosheets encapsulated Cu(OH) nanorods (Cu(OH)@CoNi-MOF) is constructed.

The Coulomb electric field formed between positive and negative charges always restricts the generation and separation of photo-irradiated electrons and holes, resulting in the limited CO photoreduction performances of catalysts. Herein, the defect engineering and high-entropy strategies are used to regulate the crystallinity of CsNaInCl perovskite materials, thus resulting in an enhanced internal polarization electric field, which overcame the Coulomb electric field and promoting the separation process of charge carriers. Moreover, the CsNa{InPrSmGdTb}Cl with Cl vacancies is prepared using the low-temperature syntheses, which overcame the challenge of extremely high-temperature requirements for high entropy alloy preparation.
