Abstract ：
The construction of covalent adaptable networks (CANs) without requiring post-modification, complex monomer synthesis routes, or expensive materials is highly desirable for advancing the practical application of dynamic covalent chemistry. In this study, the commercially available acrylate monomer, diacetone acrylamide (DAAM) was first polymerized using a conventional, free radical polymerization method. Subsequently, the resulting polymer was cross-linked with amine-based agents under hot-processing conditions to form aliphatic imine-linked CANs. The obtained materials exhibited glass transition temperatures (Tg) ranging from 95 to 107 degrees C, along with good thermal stability, mechanical, and thermomechanical properties. All samples demonstrated mechanical recyclability with post-recycled specimens retaining approximately 80% of their original tensile strength and Young's modulus, indicating a slight deterioration. Gel content analysis and structural characterization of both pristine and recycled samples indicate that the observed reduction in mechanical properties and Tg (by 70 degrees C) originated from a decrease a cross-linking density and partial cleavage of aliphatic ketone moieties. Furthermore, the aliphatic imine structure endowed all samples with acid-triggered degradability. This facile strategy for fabricating acrylate-based imine CANs establishes a versatile framework for developing reprocessable and hydrolyzable polymeric materials.

Abstract ：
In this study, SEM observation showed that in four different CB/NRs, as the amount of filled CB increased, CB agglomeration became more serious, and the CB shape wasn't a simple sphere. Combining FEA with machine learning, the study optimized CB particle structure parameters, shape, and the aspect ratio of the ellipse. Using these optimized parameters, it established a 3D stochastic model without aggregates and a 3D model with aggregates to study the uniaxial tensile mechanical behavior of CB/NRs, adopting the Mooney-Rivlin phenomenological model. The results indicated that the ellipsoidal particle model was slightly better than the spherical one in predicting the mechanical behavior of CB/NRs. Specifically, the Random Forest algorithm fitting, cross-validation, and grid search for hyperparameters to obtain the minimum RMSE had high prediction accuracy and fitting effectiveness. The optimal aspect ratio range was determined to be 2.2-2.4. Moreover, compared with experimental results, the RVE model with aggregates described the constitutive behavior of CB/NRs more accurately, better addressed the large deviations between FE simulation and experimental curves at high CB volume fractions in CB/NRs, and provided modeling solutions for CB/NRs.

Abstract ：
Traditional ionic conductive hydrogel was prepared by chemically crosslinking the polymer chains to form network. However, the chemically crosslinked ionic conductive hydrogel usually showed limited elongation at break and high hysteresis during stretching process. Here, a simple strategy of synthesizing fully physically crosslinked ionic conductive supramolecular hydrogel without chemical crosslinker was purposed. Hydrophilic salt not only act as the ion supplier, but also provide the spatial confinement effect to form the completely physically crosslinked hydrogel. Firstly, CaCl2 was used as the representative salt. The optimal PVA/PAM/CaCl2 ionic conductive hydrogel (PPC), showed excellent tensile performance (2400.3 +/- 140.63 %), anti-freezing performance (-28.8 degrees C), high conductivity (4.8 +/- 0.01 S/m), excellent stability at room temperature, low hysteresis, and high transparency. The conductivity of PPC showed no sensitivity to the tensile strain. This innovative combination enables PPC ionic conductive hydrogel to have extraordinary versatility. The flexible allsolid-state supercapacitor assembled with PPC ionic conductive hydrogel as the electrolyte has a high area specific capacitance (136.9 mF/cm2). The prepared supercapacitor can maintain good stability under certain tensile deformation (The capacitance retention rate was 87.7 % when stretched at 200 %). Moreover, other high hydrophilic salts including LiCl, ZnCl2, MgCl2 and AlCl3 were used to prepare ionic conductive PVA/PAM hydrogel to verify the universality of this preparation method.

Abstract ：
Thermochromic smart windows offer energy-saving potential through temperature-responsive optical transmittance adjustments, yet face challenges in achieving anti-UV radiation, fast response, and high-temperature stability characteristics for long-term use. Herein, the rational design of Hofmeister effect-enhanced, nanoparticle-shielded composite hydrogels, composed of hydroxypropylmethylcellulose (HPMC), poly(N,N-dimethylacrylamide) (PDMAA), sodium sulfate, and polydopamine nanoparticles, for anti-UV, fast-response, and all-day-modulated smart windows is reported. Specifically, a three-dimensional network of PDMAA is created as the supporting skeleton, markedly enhancing the thermal stability of pristine HPMC hydrogels. Sodium sulfate induces a Hofmeister effect, lowering the lower critical solution temperature to 32 degrees C while accelerating phase transition rates fivefold (30 s vs. 150 s). Intriguingly, small-sized polydopamine nanoparticles simultaneously enable high luminous transmittance of 66.9% and outstanding anti-UV capability. Additionally, the smart window showcases a high solar modulation (51.2%) and maintains a 10.2 degrees C temperature reduction versus a glass window during all-day modulation applications. The design strategy is effective, opening up new avenues for manufacturing fast-response and durable thermochromic smart windows for energy savings and emission reduction.

Abstract ：
Polyacrylamide (PAM) serves as an effective thickening agent for oil recovery. However, its viscosity loss during underground transport significantly reduces oil recovery efficiency in reservoir applications. To solve this problem, polyurethane was selected for microencapsulation of PAM through a simple emulsion polymerization method in this work. It is worth mentioning that non-toxic and renewable D-sorbitol was used as a chain extender in the synthesis of polyurethane microcapsules instead of the commonly used diols or diamines obtained from non-renewable petroleum resources, which has not been reported in previous reports. Mechanical stirring was used to simulate the state of polymer subjected to shear during stratigraphic transport. The releasing performance of the microcapsules was characterized by measuring the change of viscosity with time. Meanwhile, we optimized the ratio of D-sorbitol to achieve the longest release time. Experiments showed that D-sorbitol was feasible as a chain extender for the preparation of microcapsules of polyurethane, and the microcapsules prepared at a concentration of 8% D-sorbitol solution had the longest slow-release time of 75 h at 25 degrees C and 500 rpm. We also prepared samples with BDO as a chain extender for comparison, and the experiments showed that SO8 has a longer slow-release time and can better meet the demand. The prepared microcapsules SO8 exhibited excellent shear resistance and heat resistance, which was attributed to the rigidity and high cross-linking density brought about by D-sorbitol as a hard chain segment of polyurethane. These PAM-containing microcapsules had a promising application in enhancing oil recovery.

Abstract ：
Among many ways that can improve the electrolysis catalysts of seawater, designing the catalyst with hierarchical nanostructure has received extensive attention because it allows a larger surface area and more active sites. In this work, the NC-enveloped CoS/NiS@Cu2S catalyst with multi-level structure was successfully synthesized by using the complex of trithiocyanuric acid and copper as the metal dopant to coat the spherical Co-Ni precursor, and then by a straightforward one-step high-temperature self-vulcanization reaction. Trithiocyanuric acid not only facilitated the sulfurization of metal elements but also served as N and C source coated on the catalyst. This method constructed structure-controllable, multi-level, and yolk-shelled nanostructure in a facile manner, greatly increasing specific surface area, expanded mass transport channels, and enhancing the exposure of active sites. Besides, the coating of N and C elements significantly increased the electrical conductivity and electrochemical activity of the catalyst. As a result, CoS/NiS@Cu2S@NC exhibited excellent hydrogen evolution performance with the small overpotential of 105, 161, and 176 mV at 10 mA cm-2 in alkaline water, simulated alkaline seawater, and alkaline seawater, respectively. The present approach is proposed as an inspirational idea of the design of cobalt-nickel-copper-based multi-level structural nanomaterials as non-platinum electrocatalysts for hydrogen evolution in seawater.

Abstract ：
Solar-driven interfacial evaporation represents a promising strategy for desalination, but improving evaporation performance in seawater is challenging. Reducing the evaporative enthalpy is an effective method to solve this issue. Herein, a highly hydratable spongy hydrogel (SPC) obtained based on the Hofmeister effect is reported. The SPC evaporator in seawater demonstrated a reduced evaporation enthalpy of 1537 J/g, achieving an impressive evaporation rate of 4.01 kg m- 2 h- 1, which is higher than that in pure water (3.82 kg m- 2 h- 1). Further research found that, benefiting from the Hofmeister effect, Cl- ions in brine inhibited the hydrogel crystallinity, increased the IW content, significantly reduced the evaporation enthalpy, and thus accelerated the evaporation rat in seawater. Furthermore, the hierarchically porous structure of the spongy hydrogel facilitates rapid water supply and mass transfer, promoting the diffusion/return of salt ions and preventing salt crystal accumulation. The long-term desalination test demonstrated that the SPC evaporator possesses strong salt resistance. This work provides new insights for designing cost-effective and salinity-resistant solar evaporators to address the challenges posed by water crises.

Abstract ：
Due to the slow kinetics of the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER), designing an efficient and stable electrocatalyst is crucial for improving the overall water decomposition efficiency. In this study, a hollow nanotube NiSe2/MoSe2/NiMoO4@CoSe2-NC encapsulated by CoSe2-embedded Ndoped carbon dodecahedral particles was successfully designed and synthesized through structural engineering, heteroatom doping strategies, and selenization reactions. The unique heterostructure formed by integrating the hollow nanotubes architecture with dodecahedral particles provides abundant active sites, thereby accelerating the water electrolysis reaction kinetics. Furthermore, NiSe2/MoSe2/NiMoO4@CoSe2-NC demonstrates superior bifunctional performance in alkaline media (1.0 M KOH), achieving low overpotentials of 101 mV for HER and 264 mV for OER at 10 mA cm- 2, with corresponding Tafel slopes of 63.1 and 58.8 mV dec- 1, respectively. When employed in a two-electrode alkaline electrolyzer assembled with this catalyst, a cell voltage of only 1.55 V is required to deliver a current density of 10 mA cm-2. At high current density, it surpasses the benchmark RuO2|| Pt/C system in both performance and cost while maintaining excellent stability.

Abstract ：
Owing to the harsh working environment in which mining trucks operate, tires tend to fail prematurely. In this study, using 53/80R63 tires as the research object, two- and three-dimensional finite element models (FEM) of tires were established. A steady-state rolling simulation analysis was carried out. A crack growth test was performed on the rubber material, and the test data were fitted using the least squares method to obtain the fatigue parameters required in this study. According to the simulation results of steady-state rolling, fatigue life prediction under different working conditions was performed using fe-safeTM software, and the effects of different load rates, inflation pressures, and vehicle speeds on tire fatigue life were analyzed. The results show that when the inflation pressure and vehicle speed were constant, with an increase in load, the life of the belt layer and the sidewall part gradually decreased, and the life of the chewing rubber part displayed a sharp decreasing trend. Under the condition of constant load and vehicle speed, with an increase of inflation pressure, the life of the belt layer gradually decreased, and the life of the sidewall part decreased significantly. Under constant load and inflation pressure, vehicle speed had little effect on the tire fatigue life.

Abstract ：
The emerging approach of in-situ polymerization of solid polymer electrolytes based on 1,3-dioxolane (DOL) possesses the advantage of low interfacial impedance and relatively high Coulombic efficiency. However, the DOL monomer conversion (C%) under Lewis acid catalysts needs to be further improved, besides their alloying ability with lithium metal to generate protective interfacial layer has been ignored. Here, the above two aims are simultaneously achieved by Indium Trifluoride (InF3) catalyst. It is demonstrated that the highest C% is up to 94% with 15 mg of InF3 in the 1 mL electrolyte (1 M LiTFSI/DOL). The optimized ionic conductivity and lithium-ion transfer number are 8.9 x 10(-5) S/cm (30 degrees C) and 0.42, respectively. The stable interface between poly-DOL and lithium metal anode could be proved by the stable over-potential (156mv, 900 h) at current density of 2.0 mA cm(-2). X-ray diffraction results confirm the presence of In and In-Li alloy peaks. After 300 cycles at 1C, the assembled Li/PDI15/LiFePO4 cells deliver a 125.2mAh/g, 90% capacity retention and Coulombic efficiency of 99.75%, respectively. This innovative and facile strategy of dual functional InF3 on the in-situ polymerization of DOL and solid electrolyte interphase formation provides new ideas for design poly-DOL based solid polymer electrolytes.
