High-throughput few-layered BN nanosheets have been synthesized through a facile chemical blowing route. They possess large lateral dimensions and high surface area, which are beneficial to fabricate effectively reinforced polymeric composites. The demonstrated composites made of polymethyl methacrylate and BN nanosheets revealed excellent thermal stability, 2.5-fold improved dielectric constan...

The morphological and structural evolution of WS2 nanosheets under electron irradiation is investigated using high-resolution transmission electron microscopy. During irradiation, the sulfur atoms that interacted with the electrons were sputtered first and the tungsten atoms began to sputter when the surrounding sulfur atoms had been sputtered. With an increasing irradiation time, the remaining...

Flexible Janus nanosheets of molecular scale thickness (3.5 nm) are massively fabricated by a sol-gel process of a self-assembled monolayer of an amphiphilic silane onto a template. Groups of both sides are tuneable, and thus performance of the nanosheets, for example, is pH responsive. As a flexible solid emulsifier, the desired species can be wrapped with an individual nanosheet, which is pH ...

We demonstrate that oxygen vacancies on the {001} facets of BiOCl nanosheets can more sustainably activate molecular oxygen for organic pollutant removal under solar light than the TiO₂ counterparts. The oxygen vacancies on the {001} facets of BiOCl nanosheets are effectively refreshed by UV light, and are also responsible for the efficient utilization of visible light to activate molecular oxy...

Molybdenum disulfide, a type of two-dimensional layered material with unique properties, has been widely used in many fields. However, an exact understanding of its toxicity remains elusive, let alone its effects on the environmental microbial community. In this study, we utilized metabolomics technology to explore the effects of different concentrations of molybdenum disulfide nanosheets on Es...

Porous high surface area thin films of nanosheet-shaped monoclinic MoO(3) were deposited onto platinized Si substrates using patch antenna-based atmospheric microplasma processing. The films were characterized by high resolution transmission electron microscopy (HRTEM), scanning electron microscopy (SEM) and electrochemical analysis. The electrochemical analysis shows original redox peaks and h...

The key challenge for fabricating electrogenerated chemiluminescence (ECL) biosensors still lies in the improvement of the sensing performance of ECL luminophores. Graphite-like carbon nitride (g-C3N4) nanosheets were prepared and the cathodic ECL performance was investigated. The ECL emission of g-C3N4 nanosheets was greatly enhanced and higher sensing sensitivity towards copper ions was achie...

The graphene nanosheets-based epoxy resin coating (0, 0.1, 0.4 and 0.7 wt %) was prepared by a situ-synthesis method. The effect of polyvinylpyrrolidone/reduced graphene oxide (PVP-rGO) on mechanical and thermal properties of epoxy resin coating was investigated using nanoindentation technique and thermogravimetric analysis, respectively. A significant enhancement (ca. 213% and 73 °C) in the Yo...

ZnO quantum dots and KNb3O8 nanosheets were synthesized by a two-step hydrothermal method for the photocatalytic reduction of CO2 to methanol where isopropanol is simultaneously oxidized to acetone . The as-prepared photocatalysts were characterized by X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDS), scanning electron microscopy (SEM), high-resolution transmission electron m...

Ultrathin V2O5 nanosheets were successfully prepared through supercritical solvothermal reaction followed by annealing treatment. The formation of ultrathin nanosheets is owing to Ostwald ripening and the effect of supercritical fluids. As cathode material for lithium batteries, the ultrathin V2O5 nanosheets exhibit a capacity of 108 mA h g(-1) at a high rate of up to 10 C at 2.4-4 V and excell...
