Summary: Ultrasound-based sonodynamic therapy using sound-responsive materials has great potential for the wireless treatment of human diseases. This study investigated the ROS generation performance of molecular sonosensitizer-loaded polymer micelles under ultrasound, and found that singlet oxygen is the primary ROS component. The ROS generation performance depends on the molecular structure and experimental conditions. Additionally, the use of nanomicelle-based carriers greatly improves the therapeutic performance of sonodynamic therapy.

Summary: Food safety and food waste are important topics of discussion in recent years. Microbial-contaminated food can lead to the infection of human pathogenic bacteria and the waste of food resources. Traditional sterilization technology has drawbacks such as changes in food flavor and high energy consumption. Sonodynamic sterilization technology, as a new non-thermal sterilization technology, shows great potential in reducing these issues. This review provides an overview of the concept, mechanism, and application of sonodynamic sterilization technology, offering scientific references for its application in the field of food sterilization.

Summary: Ultrasound-triggered sonodynamic therapy has shown great potential for cancer treatment. However, traditional sonosensitizers have low efficiency, short retention time in cancer cells, and poor tumor selectivity. Therefore, there is a strong need for sonosensitizers with higher efficacy, longer retention in tumor cells, and greater specificity. In this study, we developed a Ti2C(OH)(X) nanosheet, which was transformed into a novel nanofiber structure sonosensitizer in the tumor microenvironment, exhibiting excellent ability to generate reactive oxygen species (ROS) under ultrasound. This nanofiber structure enabled high retention of the sonosensitizer in the tumor and effectively and selectively killed cancer cells.

Summary: This paper investigates the adsorption and sensing properties of transition metal-doped WSSe gas-sensitive devices towards H2, CO, and CO2 gases related to thermal runaway in Li-ion batteries using density functional theory. The results show that Ti, Mn, and Mo dopants preferentially bind to the S-surface of the WSSe monolayer, and all three monolayers exhibit significantly improved sensing characteristics, with chemisorption towards CO. Band structure analysis suggests that the Ti-WSSe monolayer has the potential to be used as a resistive CO detection sensor. Recovery time calculations indicate the reuse capabilities of the gas-sensitive devices. Mn-WSSe monolayer shows potential for H2 detection, while Mo-WSSe monolayer is more suitable for CO2 detection. This work lays the foundation for potential gas-sensitive applications of WSSe monolayer in thermal runaway scenarios, advancing research in gas sensing domains.

Summary: This paper investigates the effects of electric and magnetic fields on the Goos-Hanchen (GH) shift in a semi-Dirac system. The results show that the magnitude and direction of the GH shift depend on various factors such as incidence angle, electric barrier height and width, and magnetic field. It is observed that there is a saltus step in GH shifts at the critical magnetic field, which decreases with increased potential barrier thickness. Additionally, the GH shift can be significantly enhanced by applying an electric field in the III region. These findings are important for the development of semi-Dirac based electronic devices.

Summary: Using full electron-phonon interactions and the Boltzmann transport equation, this study investigates the phonon scattering channel and electrical properties of graphene under anharmonic phonon renormalization (APRN). The results show that the APRN reduces the phonon frequency and three-phonon phase space with increasing temperature, affecting the acoustic branch more than the optical branch. The thermal conductivity of graphene decreases after considering three- and four-phonon scattering, and the primary scattering channels are identified. Furthermore, the APRN increases the strength of electron-phonon coupling and leads to an increase in n-type electric resistance at room temperature.
