Abstract Carbon dots (CDs) is a class of zero-dimensional carbon nanomaterials with favorable stability and optical properties. However, CDs in solid state often suffer from fluorescence quenching due to π-π stacking of conjugated systems, like most small molecules or organic dyes. Herein, we prepared the CDs that generate bright yellow luminescence in solid state without any additional matrix, meanwhile the solid CDs are inclined to assembly into spherical structure. While the CDs are dissolved...

Abstract Surfactants offer a tunable approach for modulating the exposed surface area of a nanoparticle. They further present a scalable and cost-effective means for suspending single-walled carbon nanotubes (SWCNTs), which have demonstrated practical use as fluorescence sensors. Though surfactant suspensions show record quantum yields for SWCNTs in aqueous solutions, they lack the selectivity that is vital for optical sensing. We present a new method for controlling the selectivity of optical S...

Abstract Nanoscale ternary chalcogenides have attracted increasing research interest due to their merits of tunable properties and diverse applications in energy and biomedical fields. In this article, silver indium sulfide quantum dots supported by glutathione and polyethyleneimine as dual-ligands have been synthesized through an environmentally friendly and reproducible aqueous method. An emission quantum yield up to 37.2% has been achieved by glutathione as co-ligand bearing electron-rich gro...

Abstract The precursor particles were successfully prepared by a facile microwave hydrothermal method. Compared with solvothermal and precipitation method, microwave hydrothermal method can greatly shorten the reaction time and increase the product yields. Nitrogen (N) doped zinc oxide (ZnO) nanoparticles were derived via one-step controllable pyrolysis of zeolitic imidazolate framework-8 (Zif-8) precursors under 550 °C. The powder X-ray diffraction (XRD) analysis, elemental mapping image, energ...

Abstract Nanofiltration (NF) membranes with tannic acid (TA) based selective layers have been intensively studied in recent years, but they still suffer from poor inorganic salt rejection. This study provides a first report on mussel-inspired co-deposition of TA and amine to obtain high-performance NF membranes. The inorganic salt separation performance of the as-prepared NF membrane can be significantly improved by optimising the amine molecular weight. The membranes prepared by TA and various ...

Abstract Solid-state electrolytes with high ionic conductivity, large electrochemical window, and excellent stability with lithium electrode are needed for high-energy solid-state lithium batteries. In this work, a novel polyethylene oxide (PEO)-Lithium bis(trifluoromethylsulphonyl)imide (LiTFSI)-nanocomposite-based polymer electrolyte was prepared by using nickel phosphate (VSB-5) nanorods as the filler. The ionic conductivity of the obtained PEO-LiTFSI-3%VSB-5 solid polymer electrolyte was fou...

Abstract Flower-like organic materials have been used for applications in supercapacitors, catalysis, corrosion science, but no report of “flower” from metal-organic compounds on porous inorganic surface has been available. Here, we report the successful fabrication of flowerlike organic-inorganic materials via the combination of TiO2-MgO film prepared on magnesium alloy through plasma electrolytic oxidation (PEO) as inorganic components and metal-quinoline, Na-8-hydroxyquinoline-5-sulfonic acid...

Abstract Understanding structure-property relationships is critical for the development of new drug delivery systems. This study investigates the properties of Pluronic smart hydrogel formulations for future use as injectable controlled drug carriers. The smart hydrogels promise to enhance patient compliance, decrease side effects and reduce dose and frequency. Pharmaceutically, these systems are attractive due to their unique sol-gel phase transition in the body, biocompatibility, safety and in...

Abstract Room-temperature sodium-sulfur (RT Na-S) batteries are seriously limited because of poor conductivity of sulfur and sluggish reaction kinetics of polysulfide intermediates. Here, we design a free-standing film, constructed from Co nanoparticles onto nitrogen-doped porous carbon nanofibers (Co@NPCNFs), to load sulfur for RT Na-S batteries. Experiment result shows that Co as catalyst can enable the rapid sodium intercalation and fast reduction reaction of the polysulfides during cycling. ...
