Rechargeable aqueous Zn‐ion batteries (ZIBs) are always regarded as a promising energy storage device owing to their higher safety and durability. However, two problems have become the main trouble for the practical application of ZIBs such as the dendrite growth of Zn metal anode in electrolyte and the freezing of water solvent at low temperature. Herein, to overcome these challenges, a new strategy, multi‐component crosslinked hydrogel electrolyte, is proposed to inhibit Zn dendrites and realize low temperature environmental adaptability for ZIBs. Benefitting from the superior inhibition effect of the polyacrylamide and dimethyl sulfoxide (DMSO) on Zn dendrites, the coulombic efficiency of the symmetric cell of ≈99.5% is achieved during the Zn plating/stripping over 1 300 h, and the assembled full‐cell demonstrates the large specific capacity of 265.2 mAh g‐1 and high cyclic stability with the capacity retention of 95.27% after 3 000 cycles. In addition, the full‐cell delivers stable operation at a wide temperature range, from 60 to −40 °C, due to the introduction of additive DMSO. This work provides an inspired strategy and novel opportunities to realize a dendrite‐free and wide‐temperature rechargeable aqueous Zn‐ion energy storage system. [ABSTRACT FROM AUTHOR]

Most thermometers suffer from thermal quenching resulting in low signal to noise ratio at elevated temperature. To overcome thermal quenching, we fabricated a negative thermal expansion (NTE) thermometer based on Sc 2 Mo 3 O 12 :Nd3+/Yb3+/Er3+ phosphor. Under 808 nm excitation, the upconversion (UC) emissions of Er3+ ions show the thermal enhancement and its 524 nm emission increases 10-fold as the temperature increased from 310 to 670 K. Furthermore, the temperature sensing behaviors are investigated. It is found fluorescence intensity ratio (FIR) of 524–559 nm is linear with temperature over a wide range of 310–790 K. The maximum relative sensitivity is 0.84% K−1 at 310 K. These results indicate such phosphor not only achieves a high sensitivity, but also exhibits excellent performances at high temperature due to its thermal enhancement. [ABSTRACT FROM AUTHOR]

Near-infrared (NIR) thermometry are attractive with their preeminent superiority in biological tissue. In this work, the thermometry probe with binary near-infrared (NIR) luminescence is prepared from Sc 2 Mo 3 O 12 :Yb/Er and ZrO 2 :Yb/Ho powders. At elevated temperature from 310 to 580 K, the emission of Er3+ significantly enhanced in negative thermal expansion (NTE) host and the emission of Ho3+ possess thermal quenching in positive thermal expansion (PTE) host. Thus, the probe offers a unique properties of simultaneous emission enhancement and quenching in different NIR wavelengths. By fluorescence intensity ratio (FIR) technique, the relative thermal sensitivity of the sensor can reach a value of 4.2% K−1 higher than NIR thermometers reported to date, while the best temperature resolution is 0.33 K. • It was the first time to obtain novel NIR thermometry based on thermal quenching and negative thermal quenching materials. • The relative thermal sensitivity of the sensor reached a value of 4.2% K−1 higher that NIR thermometers reported to date. • The best temperature resolution was 0.33 K, which revealed the thermometry with high accuracy.

Green-ripe disorder often occurs when banana fruit (Musa AAA group) ripen at high temperature above 25 °C. In this study, the effect of modified atmosphere package (MAP) + 1-methylcyclopropene (1-MCP) treatment on the shelf-life quality of banana after high temperature storage was studied. The results showed that 300 nL L-1 1-MCP treatment combined with MAP could prevent the occurrence of green-ripe disorder in banana stored at high temperature, reduce ethylene production and respiration, then delay senescence and ripening, and reduce disease incidence and finger drop of fruit. Further analysis showed that the combined treatment decreased the content of reactive oxygen species (ROS) and enhanced the activity of defense-related enzymes and antioxidants. By inhibiting the activity of cell-degrading enzymes, the treatment increased lignin and cellulose content and maintained cell wall integrity. In addition, the treatment regulated the contents of endogenous hormones indole-3-acetic acid and abscisic acid, thus delaying the softening of fruit. This work provides a theoretical foundation for the storage and transportation of banana fruit at high temperature.
