Although rechargeable aqueous zinc batteries are cost effectiveness, intrinsicly safe, and high activity, they are also known for bringing rampant hydrogen evolution reaction and corrosion. While eutectic electrolytes can effectively eliminate these issues, its high viscosity severely reduces the mobility of Zn2+ ions and exhibits poor temperature adaptability. Here, we infuse acetamide molecules with Lewis base and hydrogen bond donors into a solvated shell of Zn[(H2O)6]2+ to create Zn(H2O)3(ace)(BF4)2. The viscosity of 1ace‐1H2O is 0.032 Pa s, significantly lower than that of 1ace‐0H2O (995.6 Pa s), which improves ionic conductivity (9.56 mS cm−1) and shows lower freezing point of −45 °C, as opposed to 1ace‐0H2O of 4.04 mS cm−1 and 12 °C, respectively. The acidity of 1ace‐1H2O is ≈2.8, higher than 0ace‐1H2O at ≈0.76, making side reactions less likely. Furthermore, benefiting from the ZnCO3/ZnF2‐rich organic/inorganic solid electrolyte interface, the Zn || Zn cells cycle more than 1300 hours at 1 mA cm−2, and the Zn || Cu operated over 1800 cycles with an average Coulomb efficiency of ≈99.8 %. The Zn || PANI cell cycled over 8500 cycles, with a specific capacity of 99.8 mAh g−1 at 5 A g−1 at room temperature, and operated at −40 °C with a capacity of 66.8 mAh g−1. [ABSTRACT FROM AUTHOR]

Summary: Grain size and weight determine rice yield. Although numerous genes and pathways involved in regulating grain size have been identified, our knowledge of post‐transcriptional control of grain size remains elusive. In this study, we characterize a rice mutant, decreased grain width and weight 1 (dgw1), which produces small grains. We show that DGW1 encodes a member of the heterogeneous nuclear ribonucleoprotein (hnRNP) family protein and preferentially expresses in developing panicles, positively regulating grain size by promoting cell expansion in spikelet hulls. Overexpression of DGW1 increases grain weight and grain numbers, leading to a significant rise in rice grain yield. We further demonstrate that DGW1 functions in grain size regulation by directly binding to the mRNA of Grain Width 6 (GW6), a critical grain size regulator in rice. Overexpression of GW6 restored the grain size phenotype of DGW1‐knockout plants. DGW1 interacts with two oligouridylate binding proteins (OsUBP1a and OsUBP1b), which also bind the GW6 mRNA. In addition, the second RRM domain of DGW1 is indispensable for its mediated protein‐RNA and protein–protein interactions. In summary, our findings identify a new regulatory module of DGW1‐GW6 that regulates rice grain size and weight, providing important insights into the function of hnRNP‐like proteins in the regulation of grain size.

Structural health monitoring (SHM) plays an increasingly vital role in guaranteeing the operation success of marine and offshore (MO) structures while reducing their risks of structural failure. In this study, a real‐time MO‐SHM system based on the highly controllable underwater robots is developed, which is functionalized with three modules, that is, underwater monitoring robots, vision‐based image processing and analyzing, and time‐dependent damage assessing and early warning. The robotic module is actuated by the hybrid driving method that combines the combustion‐based actuators (ejection) and propeller thrusters (propulsion) for transient actuation ability and well reliability in complex underwater environments. The image processing and analyzing module is conducted based on the You Only Look Once (YOLO)‐Underwater model that is expanded by the transfer learning and attention mechanisms and the underwater preconditioning and warning correction added for the specific underwater concrete identification. The damage assessing and early warning module is achieved by the time‐dependent hybrid analytic hierarchy process method that is integrated with the ordered weighted averaging and entropy weight method for more objective assessment and feedback. The reported MO‐SHM system provides design guidance for the next‐generation multifunctional underwater devices that combine analyzing and early warning for underwater concrete structures.

This letter proposes a N‐way planar power divider/combiner using a combination of a Gysel power divider and a ring coupler. This innovative approach enables the realization of a fully planar multiway (>2) Gysel power divider. By replacing the common point of the conventional Gysel power divider with a ring coupler, the entire symmetrical divider can be implemented on a two‐layer printed circuit board. To validate the design concept, an eight‐way planar power divider is designed, fabricated, and tested. Experimental results obtained within the frequency range of 5.10–7.25 GHz (34.8% fractional bandwidth) demonstrate excellent performance. The insertion loss is below 1.24 dB, the input port return loss exceeds 12.65 dB, the output ports exhibit return loss greater than 14.83 dB, the isolation exceeds 22.41 dB, and the maximum measured phase imbalance is within ±2.7°.

An angle sensitive transmission metasurface unit structure is designed in this paper. The metasurface unit presents a good transmission performance for the TE wave incidence, and has a linear phase response with the maximum phase difference up to 180° when the incidence angle changes in the range of −45° and +45°. Moreover, a reconfigurable design of the metasurface unit is realized by loading a varator, and the phase difference is extended to 270° to satisfy the demand of multibit metasurface. Based on the characteristics of angle sensitivity and reconfigurability of the metasurface unit, combined with the control of the varactor and the unit tilt angle, a new 1‐bit digital coding angle sensitive metasurface is proposed. The metasurface has a specification of 20 × 20 and a center frequency of 10 GHz. Both the simulation and measurement show that different transmission is realized for incident waves at different incident angles. It can form different beams, which can be used for multibeam modulation with the same frequency and same polarization. [ABSTRACT FROM AUTHOR]
