Summary: This paper proposes a one-way colorimetric sweat sampling and sensing system based on a Janus fabric using interfacial modification techniques. The Janus fabric's opposite wettability enables quick movement of sweat from the skin surface to the hydrophilic side and colorimetric patches. This system not only facilitates sweat sampling but also prevents backflow of colorimetric reagent, eliminating potential epidermal contaminations. Visual and portable detection of sweat biomarkers, including chloride, pH, and urea, is achieved, bridging the gap between sweat sampling and a friendly epidermal microenvironment.

Summary: Narrow-bandgap Sn-Pb mixed perovskite single crystals show great potential as photoactive materials for efficient and low-cost near-infrared (NIR) photodetectors. However, the phase separation issue during crystallization process leads to the degradation of optical and electronic properties. In this study, a low-temperature space-confined technique (LT-SCT) is proposed to reduce the crystallization velocities and create pure-phase (FASnI(3))(0.1)(MAPbI(3))(0.9) single crystals. These crystals exhibit excellent crystallinity, high hole mobility, and low surface trap density, enabling their application in self-powered NIR photodetectors with outstanding performance. The work contributes to the development of Sn-Pb mixed perovskite single crystals and offers a promising candidate for efficient and low-cost NIR photodetection.

Summary: By leveraging the participation of localized excited triplet states from both donor and acceptor segments, an ingenious molecular design was employed to significantly boost the reverse intersystem crossing (RISC) rates of red thermally activated delayed fluorescence (TADF) emitters. The molecule DBBPZ-IDPZ showed 15.7 times accelerated RISC rate and a higher photoluminescence quantum yield of 98.1% compared to the control molecule. The red OLED based on DBBPZ-IDPZ exhibited a significantly improved external quantum efficiency of 26.0%, which is approximately triple that of the control device. This work provides new insights into the molecular design tactic of high-performance red TADF OLEDs.
