Integrated energy‐storage sensing devices promote greatly the miniaturization and integration of wearable electronic devices. However, they still face long‐lasting challenges of tailored semi‐integrated configuration or highly‐coupled sensing and energy storage functions. Herein, an unprecedented all‐in‐one sensing supercapacitor (ASS) is proposed for independent and synchronous strain sensing and self‐powering. The ASS features a shared configuration, endows it with several key features, including reversible changes of ion‐transport paths and resistance in porous electrolyte, robust electron transport in the dense electrode, and stable interface resistance in the chain‐entangled interfaces. These guarantee reliable sensing and charge‐discharge processes under compression. Consequently, the ASS exhibits satisfactory electrochemical performance, including low interface‐resistance, high areal‐capacitance (37.9 mF cm ⁻² ), and good stability (98.8% capacitance retention after 5000 cycles), which can be well maintained under wide compressive strains of 0%∼80% and 5000 cyclic compression‐release. Furthermore, good sensing characteristics are also achieved with wide detection ranges up to 80% compressive strain and superior durability (>7000 cycles). The ASS also shows minimal mutual interference in synchronous sensing‐powering mode over harsh conditions, highlighting its great multi‐scenario applications. These findings open up a new perspective for highly efficient all‐in‐one energy‐storage sensing devices toward practical wearable applications.

Chemotherapy and photothermal therapy (PTT) hold great potential in cancer treatment, but face challenges including low therapeutic agent penetration and insufficient photothermal effects. Therefore, it is necessary to design a nanomedicine delivery system capable of both PTT and controlled drug release. Here, a bowl‐shaped PDA@UiO‐66 nanorobot was designed for efficient loading of doxorubicin (DOX), enabling synergistic cancer cell death through combined chemotherapy and PTT. The superior photothermal‐effect bowl‐shaped Polydopamine (PDA) was synthesized using an emulsion‐induced interface anisotropic assembly method, and UiO‐66 was grown on its surface through functional groups to enhance the drug‐loading capacity. The asymmetric structure of nanorobots enables efficient self‐thermophoretic motion under Near‐infrared (NIR) irradiation. Compared to static nanorobots, NIR irradiation not only drives nanorobot to exhibit self‐thermophoretic motion and elevates temperature but also triggers DOX release via hyperthermia, enhancing cancer cellular uptake of DOX and thereby significantly improving the combined chemo‐photothermal therapeutic efficacy. This novel therapeutic strategy, which combines self‐propelled motion with photothermally responsive drug release, overcomes the technical limitations of decoupled motility and drug release in traditional nano‐delivery systems. It achieves precise photothermal‐controlled drug release and significantly enhances tumor cell‐killing efficiency. This approach provides an innovative strategy for developing multifunctional integrated nanodrug delivery platforms.

Experimental teaching in chemical engineering is crucial in cultivating students’ innovative thinking and practical ability. However, traditional teaching methods face issues such as mainly focusing on verification experiments, insufficient integration of cutting-edge technologies, and lack of teamwork. This paper proposes a series of strategies to address these challenges, including optimizing experimental content, adopting diversified teaching methods, creating an open learning environment, strengthening industry connections, establishing an effective feedback and evaluation mechanism, and cultivating laboratory culture. By integrating cutting-edge technology into experiments, introducing teaching methods such as project-based learning and flipped classrooms, and creating a laboratory atmosphere that encourages questioning, exploration, and collaboration, students’ innovative thinking and practical ability can be stimulated, laying the foundation for their success in the ever-changing chemical industry.
