As a transparent thermoelectric oxide, gallium‐doped zinc oxide (GZO) has the potential to power wearable or portable electronics and may be used in the integrated circuits industry for chip cooling. Constructing ZnO–GZO interfaces has been proposed as an effective strategy for improving thermoelectric performance of GZO thin films. However, without the aid of band structure calculation for multilayered films, it is hard to directly elucidate the underlying mechanisms of carrier transport. Weighted mobility is an indicator that reveals the inherent electronic transport properties like carrier scattering, electronic band structure, and so on. Thus, to further investigate the effects of ZnO–GZO interfaces on electrical properties of GZO thin films, the structures containing different numbers of ZnO–GZO interfaces were designed and the correlations among numbers of ZnO–GZO interfaces, weighted mobility, and electrical properties were explored. It was found that with more ZnO–GZO interfaces, the weighted mobility increased, and the power factor values also improved as well. Consequently, an enhanced power factor value reached 439 μW m−1 K−2 at 623 K. This work demonstrated the beneficial effects of multiple interfaces on the improvements of electrical transport performance through analyzing weighted mobility, which laid a foundation for further optimization of thermoelectric performance.

“…[58] Carbon quantum dot (CQD)decorated ZnO (C/ZnO) was selected as the functional nanoparticles due to its antibacterial performance, excellent photocatalytic performance, and ability to generate ROS upon infrared or visible light exposure. [59,60] On top of that, CQDs and polydopamine (PDA) have excellent photothermal performance under irradiation with NIR light, which also contribute to killing bacteria. The resultant DFT-C/ZnO hydrogel possessed remarkable photothermal and photodynamic antibacterial activity by rapidly generating ROS and hyperthermia under coirradiation with 808 nm NIR light and 660 nm red light.…”

Due to global aging problems, the rising number of patients suffering from chronic or hard‐to‐heal acute wounds imposes a significant burden on healthcare systems. Wound healing is a complicated and dynamic physiological process with distinct molecular and cellular levels at each phase. Despite numerous strategies and advanced wound dressings being developed, successful wound management through smart dressing materials that can adapt to changing wound microenvironments and address the needs of wounds at different stages remains a big challenge. Over the last decade, hydrogel‐based dressings have emerged as one of the most potent biomaterials for wound treatment with favorable biological characteristics and a high potential for active intervention during the wound‐curing process. In the current contribution, we present the most recent progress in smart hydrogel dressings that can regulate the release of therapeutics in response to external stimuli (such as light) as well as endogenous changes in wound environments (e.g., temperature, pH, glucose, and reactive oxygen species) to facilitate wound healing. We also introduce the cutting‐edge technologies of intelligent “sense‐and‐treat” dressings through a combination of built‐in sensors or sensing molecules with responsive hydrogels, which enable real‐time monitoring of wound conditions and prompt on‐demand therapy.

Phase change materials (PCMs) have been widely recognized as efficient solutions for thermal management across various industries, including logistics, construction, electronics, and others. Nevertheless, these materials encounter challenges such as leakage, poor thermal conductivity, and supercooling. To address these challenges, a comprehensive examination was conducted on the recent advancements pertaining to silicon‐based materials. These studies include their application as high temperature PCMs, as encapsulation matrices, and their integration as additives to enhance material properties. Aluminum–silicon (Al−Si) alloys offer a viable thermal management solution for high‐temperature applications, such as those found in car batteries. Silicon dioxide (SiO2), silicon carbide (SiC), and silicate‐based minerals have demonstrated the ability to synergistically encapsulate PCMs to prevent leakage, enhance thermal conductivity, and mitigate supercooling. However, the efficacy of these strategies in reducing supercooling varies, and a considerable number of studies have reported an exacerbation. Therefore, appropriate material selection and fine tuning for formulation are necessary. This review critically assesses silicon‐based materials as a component of PCM composite that have been developed over the years. Also, it presents an academic analysis of the selection of silicon‐based materials and the design strategy for PCM composites to optimize PCM formulations according to specific desired properties.
