Significance Glassy polymers are widely used as structural materials in aerospace vehicles, airplanes, automobiles, biomedical devices, and so on. However, glassy difficult to self-heal at room temperature due their frozen molecules. For example, the window glass of airplanes made polycarbonate cannot repair mechanical damages autonomously, which could lead a catastrophe. To impart with self-healing ability, we take advantage high mobility hyperbranched polymers, introduce hydrogen...
Loose connective tissue that widely exists in the human body is very tough and healable, due to unique network formed by hyperbranched linear fibers. Inspired such structure, we develop a class of healable polymeric glasses (THGs) tailoring amine-carboxylate salt bridges between polymer high-molecular-weight copolymers. The high density leads yield strength (up 49.7 MPa) Young's modulus (1.1 GPa) THGs. Meanwhile, large free volume molecular entanglements copolymers enable outstanding...
Natural rubber (NR) material is indispensable in various fields of our daily life, while its preparation usually involves toxic cross-linking agents and energy-consuming vulcanization processes. The permanent network NR products also makes degradation recycling difficult. Herein, a fully biosourced, vulcanization-free developed by simply introducing carrageenan (KC) the matrix via facile aqueous mixing method. nonrubber components (NRCs) on latex particles are crucial importance for this art...
In this paper, the graphene oxide loaded with nano titanium dioxide (TiO2-GO) was synthesized through 3-isocyanatopropyltrimethoxysilane (IPTMS) and characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction analysis (XRD), photoelectron (XPS), scanning electron microscopy (SEM), thermogravimetric (TGA), dispersion test. The results illustrated our modification successful TiO2-GO transferred from hydrophilic to hydrophobic. That greatly enhanced dispersity of in epoxy...

This study aimed to screen effective biomarkers for medical practice well figuring out immune infiltration situations between circulation intervertebral discs. Methods: Gene expression profiles of GSE124272 was included differentially analysis, WGCNA analysis from GEO database, other GSE series were used validation datasets. A methods conducted verify the robustness hub...
Suppressing vibrations and noises is essential for our automated society. Here, inspired by the hierarchical dynamic bonds phase separation of mussel byssal threads, we synthesize high-damping supramolecular elastomers (HDEs) via simple one-pot radical polymerization butyl acrylate (BA), acrylic acid (AA), vinylimidazole (VI). Interestingly, AA VI not only form hydrogen ionic simultaneously but also segregate into aggregates different sizes, thereby successfully mimicking structure threads....
A healable poly(urethane-urea) elastomer with ultra-high mechanical strength enabled by tailoring multiple relaxation dynamics of hierarchical hard domains.
Abstract The growing concern regarding widespread plastic pollution has propelled the development of sustainable self‐healing plastics. Although considerable efforts have been dedicated to fabricating plastics, achieving rapid healing at room temperature is extremely challenging. Herein, we developed an ultra‐fast‐healing glassy polyurethane (UGPU) by designing a hyperbranched molecular structure with high density multiple hydrogen bonds (H‐bonds) on compliant acyclic heterochains and...
Electrified synthesis of high-value organonitrogen chemicals from low-cost carbon- and nitrogen-based feedstocks offers an economically environmentally appealing alternative to traditional thermocatalytic methods. However, the intricate electrochemical reactions at electrode surfaces pose significant challenges in controlling selectivity activity, especially for producing complex substances such as
Intervertebral disk degeneration (IDD) is a chronic inflammatory disease with intricate connections between immune infiltration and oxidative stress (OS). Complex cell niches exist in degenerative intervertebral (IVD) interact each other regulate the homeostasis together. However, few studies have used longitudinal approach to describe response of IDD progression. Here, we conducted conjoint analysis bulk-RNA sequencing single-cell sequencing, together series techniques like weighted gene...

Mushroom cultivation is a sustainable agricultural waste utilization method, but the lack of high-value produced spent mushroom substrate (SMS) has hindered development cultivation-based circular systems. Conversion and SMS via Protaetia brevitarsis larvae (PBL) have proven to be AASMS strategy. However, Auricularia auricula (AASMS), which contains woodchips, less palatable digestible for PBL. To solve this problem, in investigation, we screened out microflora (MF) fermentation by comparing...
