Electrochromic (EC) glazing can regulate solar heat gain, but the control signal affects the balance between cooling and heating energy use. This study compares the Load strategy, which uses predicted sensible load, with the fixed temperature-based T24 strategy, which uses a 24 °C upper switching threshold. Both strategies were implemented through the EnergyPlus Energy Management System (EMS) under identical building, heating, ventilation, and air-conditioning (HVAC), thermostat, weather, and EC glazing conditions across 384 worldwide EnergyPlus Weather (EPW) records. EC (Load) reduced cooling electricity across most climates but increased heating gas use, with larger penalties in colder regions. The resulting annual energy-use intensity (EUI) was 146.54 kWh m^-2 year^-1 for EC (Load) and 145.23 kWh m^-2 year^-1 for EC (T24), while the carbon-equivalent response varied geographically because of the competing electricity and heating effects. These results indicate that the Load strategy primarily redistributes energy use between cooling and heating rather than providing a universal annual-energy advantage, thereby demonstrating the climate-dependent energy trade-offs associated with this strategy.

Metal-organic frameworks (MOFs) have emerged as a versatile class of porous nanomaterials for cancer therapy owing to their programmable compositions, ordered architectures, and multifunctional properties. Among them, meso-tetra(4-carboxyphenyl) porphyrin (TCPP)-based MOFs have attracted particular attention because the porphyrinic ligand serves not only as a structural building block but also as an intrinsic photosensitizer and sonosensitizer, while framework metal nodes provide catalytic, imaging, and radiosensitizing functions. The synergistic integration of these components enables TCPP-based MOFs to function as multifunctional theranostic platforms rather than conventional drug carriers. In this Perspective, we organize recent advances around a structure–active center–mechanism–therapeutic outcome framework for interpreting TCPP-based MOFs in cancer theranostics. We first discuss the coordination chemistry of TCPP, representative framework topologies, and the distinct roles of metalloporphyrin centers and framework metal nodes in regulating reactive oxygen species generation, catalytic activity, ferroptosis, and multimodal imaging. We then use this framework to examine their applications in photodynamic, chemodynamic, sonodynamic, radiotherapy/radiosensitization, and radiodynamic strategies, as well as drug-delivery-enabled combination therapy and image-guided theranostics. Finally, we highlight current challenges associated with biosafety, degradation, scalable synthesis, and biological barriers, and outline future opportunities for developing structurally programmable, stimulus-responsive, and clinically translatable TCPP-based MOFs for precision oncology.

Proton exchange membrane water electrolysis (PEMWE) is regarded as a practical hydrogen production method due to its advantages such as smaller resistance loss, higher current density, and higher hydrogen purity. However, the efficiency of PEMWE technology is severely hindered by the slow kinetics and the high reaction barrier of the oxygen evolution reaction (OER). Therefore, developing cost-effective, efficient, and stable OER electrocatalysts is urgently needed. The RuO₂-based elec-trocatalysts have been proven to be promising alternatives to Ir-based catalysts due to their excellent electrocatalytic activity and high adaptability in acidic environ-ments. This review comprehensively summarizes and discusses the morphological control strategies, advanced modification strategies, and structural synergy of RuO₂ catalysts. Furthermore, the composition and industrial development status of PEMWE are elaborated, along with the current research progress of RuO₂ as an an-ode in electrolysis. Finally, relevant suggestions for RuO₂ research and practical ap-plications are presented, the challenges facing practical deployment are analyzed, and future research directions are outlined.
