Summary: By using epichlorohydrin as a cross-linking agent and red radish pigment as a pH indicator, a network-like cross-linked cellulose aerogel film (R-CEF) with water-responsive properties was successfully fabricated. The R-CEF showed high porosity and good compatibility due to the cross-linked structure of cellulose aerogel film (CEF). SEM analysis revealed that the addition of red radish pigment changed the structure of CEF, resulting in intelligent response characteristics of R-CEF-7 upon water absorption. The color change of R-CEF-7 from red to pink in acidic conditions (pH=3 to pH=5) and from pink to yellow in alkaline conditions (pH=10 to pH=13) demonstrated its pH-responsive properties.

Summary: Stable cross-shaped CsPbI3 nanoplates with red emission were successfully synthesized by the assistance of YCl3. The anisotropic growth of the CsPbI3 nanocrystal and the dissolution of four corners lead to the formation of cross-shaped nanoplates. The incorporation of Y3+ dopant widens the bandgap and enhances the stability of the nanoplates. These adjustable wavelength and highly stable nanoplates show great potential in high-definition displays.

Summary: Low-color-temperature white light-emitting electrochemical cells (LECs) based on mixed CdZnSeS/ZnS quantum dots (QDs) and an ionic transition metal complex (iTMC) carrier injection layer are demonstrated. These white LECs exhibit white electroluminescence (EL) with a low correlated color temperature (CCT) < 1800 K and a high color rendering index (CRI) > 90 under lower currents. Removing the blue QDs from the white QD LECs not only prevents the CCT from increasing under a higher device current but also improves the device efficiency.

Summary: In this study, a covalent adaptable network based on the thermoreversible cross-linking of an ethylene-propylene rubber through Diels-Alder reaction was prepared through melt blending. The research shows that this rubber has the potential to compete with conventionally cross-linked elastomers and can be recycled through a simple melt processing step. Furthermore, the addition of reduced graphene oxide to the thermoreversible rubber significantly improves its stiffness and thermal conductivity.

Summary: In this work, highly sensitive low-humidity sensors based on Au nanoparticles-modified sulfonate metal-organic frameworks (MOFs) were constructed, and the sensor was applied in low-humidity detection. The small Au nanoparticles enhance the hydrophilicity of the sensing material and catalyze the decomposition of water molecules, leading to a high response of the sensor in the humidity range of 5% RH-30% RH. The as-prepared sensor exhibits high sensitivity, good linearity, and long-term stability, making it suitable for the monitoring of humidity in biscuit storage environments.

Summary: Humidity is a physical quantity that measures the concentration of water vapor in the air. Humidity sensors are widely used in various fields due to their advantages of portability, easy fabrication, low cost, high sensitivity, and fast response. However, developing high-performance low humidity sensors still faces challenges due to the small amount of water molecules they can adsorb and the limitations of harsh environments. This paper reviews the research progress of low humidity sensors for nearly three decades, including the necessity of low humidity detection, measurement methods, and different types of sensors.

Summary: The influence of molecular design on the performance of organic light-emitting diodes (OLEDs) was studied by designing four blue-emissive compounds. Phenyl group insertion enhanced conjugation and regulated the locally excited component, leading to high photoluminescent quantum yield and maintained charge transfer property. On the other hand, a large group substitution hindered aggregation and resulted in poor carrier mobilities. By utilizing these design strategies, non-doped OLEDs with balanced carrier mobilities, high external quantum efficiency, and low efficiency rolling-off were realized.
