Published: January 2025

Architectural thermo-responsive dynamic windows offer an autonomous solution for solar heat regulation, thereby reducing building energy consumption. Previous work has emphasized the significance of thermo-responsive windows in hot climates due to their role in solar heat control and subsequent energy conservation; conversely, our study provides a different perspective. Through a global-scale analysis, we explore over 100 material samples and execute more than 2.8 million simulations across over two thousand global locations. World heatmap results, derived from well-trained artificial neural network models, reveal that thermo-responsive windows are especially useful in climates where buildings demand both heating and cooling energy, whereas thermo-responsive windows with optimal transition temperatures show no dynamic features in most of low-latitude tropical regions. Additionally, this study provides a practical guideline and an open-source mapping tool to optimize the intrinsic properties of thermo-responsive materials and evaluate their energy performance for sustainable buildings at various geographical scales.

Buildings, especially installed windows, account for a large proportion of global energy consumption. The research trend of smart windows leans towards multi-functional integration, concurrently achieving solar modulation and thermal management. However, sometimes a one-time performance switch cannot meet demands, making the design of multi-gradient adjustable smart windows particularly important.

Photothermal therapy (PTT) is a promising treatment strategy for malignant tumors. Photothermal agents which can achieve efficient photothermal conversion in the NIR-II region plays crucial roles in this remedy. Here, we report one type of thermo-responsive gold nanorod vesicles USGRV-17-AAG for combined NIR-II photothermal therapy and chemotherapy of solid tumors.

Here we report the highly efficient upconversion luminescence (UCL) and optical temperature sensing based on the novel host of KYb(MoO) doped with trivalent lanthanide (Ln) ions at 980 nm excitation. The high Yb concentration and unique ordered layer structure in KYb(MoO) host are beneficial for the enhancement of UCL efficiency by improving the absorption and the negative migration of excitation energy. Ho, Er, and Tm ions were selected to singly dope the KYb(MoO) host, achieving three primary colors of red, green, blue UCL, respectively.

February 2023

School of Chemistry and Chemical Engineering, Wuhan Textile University, Wuhan 430073, China.

Adjusting sunlight and thermal radiation from windows is important in efficient energy-saving applications. A high solar modulation (Δ) capability as well as a high luminous transmittance () are the ultimate aim of smart windows. In this study, hydroxypropyl cellulose (HPC), W-doped VO, and poly--iso-propylacrylamide (PNIPAm) composite hydrogel films were produced.
