Perovskite nanocrystals (PNCs) are promising active materials because of their outstanding optoelectronic properties, which are finely tunable via size and shape. However, previous synthetic methods such as hot-injection and ligand-assisted reprecipitation require a high synthesis temperature or provide limited access to homogeneous PNCs, leading to the present lack of commercial value and real-world applications of PNCs. Here, we report a room-temperature approach to synthesize PNCs within a liquid crystalline antisolvent, enabling access to PNCs with a precisely defined size and shape and with reduced surface defects.

- The study focuses on improving the efficiency of organic light-emitting diodes (OLEDs) by modifying the hole transport layer (HTL) with core-shell nanoparticles, specifically silver nanoparticles (Ag-NPs) embedded in a tungsten polyoxometalate compound (POM).
- The research demonstrates that Ag-NPs enhance OLED performance through better hole injection, conductivity, and beneficial optical effects such as Localized Surface Plasmon Resonance (LSPR), thereby improving carrier balance and exciton recombination rates.
- A comparative analysis with POM gold nanoparticles (POM-Au NPs) indicates that the POM-Ag NPs offer significant advantages, suggesting this innovative approach could
This narrative review aimed to identify young cancer survivors' behaviours, experiences, and perspectives concerning physical activity, and identify useful strategies for promoting a healthy lifestyle. A manual search on the following databases was conducted: PubMed, Scopus, and Web of Science. The search was conducted between June 1, 2023, and April 12, 2024.

- * A systematic literature review analyzed 22 studies (including 13 randomized controlled trials) from 2012 to 2022, focusing on the effectiveness of PA and diet interventions for AYA cancer survivors.
- * While most interventions targeted PA—mainly aerobic and resistance training—and were generally well-received, there is a significant gap in research on nutrition, indicating a need for further studies to explore dietary impacts on AYA cancer survivors.
Article Synopsis
- - The study examined how electric conduction in molybdenum oxide films changes with temperature and electronic structure through experiments involving current-voltage measurements and spectroscopic ellipsometry.
- - Both amorphous and crystalline molybdenum oxide samples had oxygen deficits and exhibited ambipolar conduction (involving both electrons and holes) at lower temperatures, while at higher temperatures (over 300°C), oxidation and improved atomic structure led to a decrease in this ambipolar behavior.
- - As temperatures returned to room level, the ambipolar conduction gradually re-emerged, resulting in a unique "metallic" behavior in electrical resistance when electrons were injected into the semiconductor.
