Avoiding wound infection and retaining an appropriate level of moisture around woundz are major challenges in care management. Therefore, designing hydrogels with desired antibacterial performance good water‐maintaining ability is particular significance to promote the development dressing. Thus a series prepared by crosslinking Ag/graphene composites acrylic acid N , ′‐methylene bisacrylamide at different mass ratios. The accelerated wound‐healing hydrogel systematically evaluated aim...
Novel composites of Ni-MOF/CNTs and rGO/C<sub>3</sub>N<sub>4</sub>were synthesized to assemble an asymmetric supercapacitor with high energy power density.
Graphene/manganese dioxide (MnO2) composite papers (GMCP) are fabricated via a simple three-step route: preparation of graphene oxide/MnO2 (GOMC) dispersion, subsequent vacuum filtration GOMC dispersion to achieve paper (GOMCP), and finally thermal reduction GOMCP generate GMCP. The morphology microstructure the prepared samples characterized by field-emission scanning electron microscopy, transmission Raman spectroscopy, Fourier transformation infrared gravimetric analysis X-ray...

A new class of multilayer films was constructed by electrostatic layer-by-layer self-assembly, using poly(sodium 4-styrenesulfonate) mediated graphene sheets (PSS-GS), manganese dioxide (MnO2) sheets, and poly(diallyldimethylammonium) (PDDA) as building blocks. UV-vis spectroscopy, field-emission scanning electron microscopy X-ray photoelectron spectroscopy were used to characterize the microstructures morphologies films. Capacitive properties synthesized film electrodes studied cyclic...
Polymeric elastomers integrated with high mechanical toughness and excellent self-healing ability can find attractive applications in electronic skin, soft robotics, electrical devices. However, simultaneously enhancing the properties of is still a great challenge because it difficult to balance effects between strong weak cross-linking bonds. Here, novel elastomer developed via one-pot polycondensation reaction bis(3-aminopropyl)-terminated poly(dimethylsiloxane) 2,4'-tolylene diisocyanate,...
Abstract. Wetlands, often called the “kidneys of earth”, play an important role in maintaining ecological balance, conserving water resources, replenishing groundwater and controlling soil erosion. Wetland mapping is very challenging because its complicated temporal dynamics large spatial spectral heterogeneity. An accurate global 30 m wetland dataset that can simultaneously cover inland coastal zones lacking. This study proposes a novel method for by combining automatic sample extraction...
Abstract Wetlands play a key role in maintaining ecological balance and climate regulation. However, due to the complex variable spectral characteristics of wetlands, there are no publicly available global 30-meter time-series wetland dynamic datasets at present. In this study, we present novel 30 m annual maps (GWL_FCS30D) using Landsat imagery on Google Earth Engine platform, covering period 2000–2022 containing eight subcategories. Specifically, make full use our prior globally...
Fluorographene (FG), which inherits the properties of graphene and fluorographite (FGi), holds great promise for applications in high-performance materials devices, including lubricants, nanocomposites, batteries, nanoelectronics. However, challenges realizing large-scale preparation little knowledge concerning FG's physicochemical hinder its practical applications. Here, a novel feasible method is developed to prepare FG through simple sonochemical exfoliation process N-methyl-2-pyrrolidone...
Although the fluorinated graphene (FG) possesses numerous excellent properties, it can not be really applied in aqueous environments due to its high hydrophobicity. Therefore, how achieve hydrophilic FG is a challenge. Here, method of solvent-free urea melt synthesis developed prepare urea-modified (UFG).
