Summary: Researchers have successfully fabricated composite hydrogels with high strength, toughness, and adhesion by a simple composite strategy. The composite gels are reinforced by a fiber fabric matrix, providing high load-bearing capability and good crack resistance. Additionally, the gel matrix exhibits good adhesion due to its soft and sticky nature. The effect of fiber fabric content on the mechanical and adhesion properties of the composite gels has been systematically studied, resulting in an optimized composite gel with significantly improved properties compared to the gel matrix.

Summary: In this paper, a RIS-assisted wireless communication system with energy harvesting is investigated. The power control of the base station and the random deployment of energy users are considered in the single information user scenario. Statistical features of the channel gains over the BS-RIS-IU and BS-RIS-EU cascaded links are characterized, and closed-form expressions for the information outage probability (IOP) of the IU and the upper bound for the energy outage probability (EOP) of EUs are derived. The analysis is further extended to include imperfect phase alignment and multiple IUs, and the correctness of the results is verified by Monte-Carlo simulation.

Summary: D-A type thermally activated delayed fluorescence (TADF) materials with aggregation-induced emission (AIE) have been developed by the methylation strategy, leading to intense emission and high quantum yield in aggregated state. Increasing dihedral angle enhances the photoluminescence quantum yield (PLQY) by 18-fold. Density functional theory (DFT) calculations reveal that these TADF molecules violate Kasha's rule, with fluorescence originating from the higher energy electronic excited state (S2) instead of the S1 state.

Summary: This article studies an intelligent reflecting surface (IRS)-aided communication system under the time-varying channels and stochastic data arrivals. It proposes a method called LETO that combines Lyapunov optimization with evolutionary transfer optimization (ETO) to solve the optimization problem. LETO decouples the long-term optimization problem into deterministic optimization problems in short time slots, ensuring queue stability, and then solves the optimization problem in each time slot using the evolutionary transfer method to achieve real-time decisions.

Summary: Different gravity fields have significant effects on the structural morphology of bone. Fluid flow and mass transfer in the bone lacunar-canalicular system (LCS) play important roles in regulating bone reconstruction. This study investigated the effects of different gravitational fields and frequencies on fluid pressure, flow velocity, and shear force on osteocytes within the LCS. The results showed that high-intensity exercise can enhance fluid flow rate and osteocyte activity, while hypergravity can enhance solute and nutrient transport. Microgravity, on the other hand, may inhibit mass transfer, potentially leading to bone loss and osteoporosis.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
