Various glassy hydrogels are developed by forming dense physical associations within the matrices, which exhibit forced elastic deformation and possess high stiffness, strength, toughness. Here, viscoplastic behaviors of hydrogel poly(methacrylamide-co-methacrylic acid) investigated stress relaxation creep measurements. We found that characteristic time gel is much smaller than amorphous polymers. The varying hydrogen bond strength leads to a broad distribution structural activation...
Developing hydrogels with new structures and extraordinary performances is fundamental mission-critical for the advancements of gel materials. Here, we report a class tough supramolecular facilely prepared by polymerizing methacrylic acid precursor solution in presence hexadecyltrimethylammonium chloride micelles. After swelling as-prepared water, strong polyelectrolyte/surfactant complexes (PESCs) are formed between weakly charged polymer chains oppositely surfactants, serving as physical...
In this study, fluorescent molecularly imprinted polymers (FMIPs), which were for the selective recognition and fluorescence detection of λ-cyhalothrin (LC), synthesized via fluorescein 5(6)-isothiocyanate (FITC) 3-aminopropyltriethoxysilane (APTS)/SiO2 particles. The SiO2@FITC-APTS@MIPs characterized by Fourier transform infrared (FT-IR), UV–vis spectrophotometer (UV–vis), spectrophotometer, thermogravimetric analysis (TGA), confocal laser scanning microscope (CLSM), electron microscopy...
Tough hydrogels usually have heterogeneous structures. Revealing microstructure formation and variations under specific conditions is important for the structure–property relationship toughening mechanism of these gels. In previous work, we reported plastic-like supramolecular with polyelectrolyte/surfactant complexes (PESCs) as physical cross-links. The gels are synthesized by polymerizing an aqueous solution methacrylic acid in presence N-hexadecyltrimethylammonium chloride micelles....
A computational model coupling electromagnetic field with a macroscopic heat and fluid flow is developed to investigate the pattern solidification in vertical continuous caster using four-port submerged entry nozzle (SEN) mold strand stirring (M-EMS S-EMS).

Abstract Fluorescent hydrogels have promising applications in biomedical and engineering fields. However, they are usually mechanically weak. Here, we report a fluorescent composite hydrogel with high toughness, which is facilely prepared by solution casting ethanol of poly(hydroxyurethane) (PHU) poly(stearyl acrylate‐ co ‐acrylic acid) (P[SA‐ ‐AAc]) followed swelling the casted film water. The water content 62–78 wt% possess remarkable mechanical performances, tensile breaking stress...
Aluminum alloy thin-walled structures have been well used in applications of energy absorption. In the present work, a bioinspired design strategy for aluminum is proposed to improve performance out-of-plane crashworthiness by altering material distribution.

The finite element model established investigate FTTC and validated experiment results....
Thermionic energy converters are solid-state heat engines to produce electricity with significant potential, whereas the output voltage is constrained by work function difference between cathode and anode. In this work, we originally apply a graphene-on-semiconductor heterojunction anode thermionic-photovoltaic (TIPV) converter additional voltage. electrons injected into graphene layer then recombined photogenerated holes. Photogenerated extracted from conduction band reinjected through an...
