Despite the rapid development of tissue adhesives, flaws including allergies, poor stability, and indiscriminate double-sided adhesive properties limit their application in medical field. In this work, Janus polyurethane patches were spontaneously prepared by adjusting difference functional group distribution between top bottom sides patch during emulsion drying. Consequently, adhesion was exhibited on surface, while surface can easily adhere to metals, polymers, glasses, tissues. The...
Core–shell structural NiS<sub>2</sub>@MoS<sub>2</sub>nanospheres have been successfully fabricated and they possess enhanced microwave absorption properties as compared to single NiS<sub>2</sub>nanospheres or MoS<sub>2</sub>nanoplates due this core–shell structure.
Abstract Underwater adhesives with injectable, organic solvent‐free, strong, fast adhesion, and hemostatic properties have become an urgent need in biomedical field. Herein, a novel polyurethane underwater adhesive (PUWA) inspired by mussels is developed utilizing the rapid post‐cure reaction of isocyanate esterification without solvents. The PUWA created through injectable two component curing process A (biocompatible prepolymer) B (dopamine modified lysine derivatives: chain extender‐LDA...
Bioadhesives are of great interest for tissue/wound closure to reduce surgical time, minimize treatment invasiveness, and prevent body fluid leakage.
This paper describes the influence of temperature, water content, and anionic type acidic-functionalized ionic liquids (ILs), 1-(4-sulfobutyl)-3-methylimidazolium hydrogen sulfate ([BsMIM][HSO4]) toluenesulfonate ([BsMIM][OTs]), on corrosion behavior Fe, Ni, 304 stainless steel (304SS). Electrochemical methods including electrochemical impedance spectroscopy (EIS) Tafel plots were used to investigate it. Also, scanning electron microscopy (SEM) was characterize nature morphology. The...
3D connected porous LGPU scaffolds with adjustable degradation and a strong anti-inflammatory effect were prepared for neural tissue repair.
A facile and flexible strategy was presented for implant modification via tannic acid mediated layer-by-layer self-assembly coatings of polyethylene glycol peptides. The obtained implants exhibit synergistic anti-fouling osteogenic performances.
The reported dynamic covalent bonds (DCBs) exhibit certain drawbacks, including sluggish reaction rates and high dissociation temperatures, which impede the reusability of DCBs cross-linked polymers. Herein, we develop a kind imidazole-urea bond (IUBs) through rapid self-catalytic between imidazole isocyanate without additional catalysts. IUBs are found to be highly reversible via thermally dissociative mechanism while also demonstrating an irreversible exchange with amines. Then, histamine...
The application of silk fibroin (SF) hydrogels is often limited by their brittleness; on the other hand, increasing ductility can lead to insufficient strength hydrogel. These drawbacks make it difficult apply treat root surface caries, which are continuously exudated crevicular fluid and have special locations shapes. Herein, we design an underwater adhesive hydrogel with a fluid-solid spontaneous transition triggered water for caries treatment. Guanidine hydrochloride (GH), amorphous...
The use of a mechanically robust and fast degradable POC-M-click–HA matchstick scaffold resulted in high fusion rates bone strengths rabbit lumbar interbody model.
Manipulation of selectivity in the catalytic electrochemical carbon dioxide reduction reaction (eCO2RR) poses significant challenges due to inevitable structure reconstruction. One approach is develop effective strategies for controlling pathways gain a deeper understanding mechanisms robust CO2RR systems. In this work, by precise introduction 1,10-phenanthroline as bidentate ligand modulator, electronic property copper site was effectively regulated, thereby directing switch. By...
During the preparation of asphalt mixtures, styrene-butadiene rubber (SBR) polymers are susceptible to thermal decomposition, which can significantly impair binder’s low-temperature performance. This study explores potential combining warming agents with waste materials enhance properties and aging resistance binder. Specifically, it examines synergistic impact Sasobit/recycled engine oil (Sasobit/REO) composites on rheological physical attributes binder (SBRAB). Utilizing fluorescence...
Functionally graded, mineralized collagen tissues exist at soft-to-hard material attachments throughout the body. However, details of how and hydroxyapatite mineral (HA) interact are not fully understood, hampering efforts to develop tissue-engineered constructs that can assist with repair injuries soft bone. In this study, spatial control mineralization was achieved in matrices using simulated body fluids (SBFs). Based upon previous observations poor bonding between reconstituted HA...
