The two-dimensional molybdenum disulfide (MoS2) nanosheet has been extensively studied as a novel photothermal transducing agent. However, top-down exfoliation to produce MoS2 nanosheets is inefficient, and MoS2 nanosheet surface modification procedures are complex. Here, we report the synchronous synthesis and surface modification of 2D MoS2 nanosheets with a polyvinylpyrrolidone (PVP)-assiste...

Self-assembling proteins offer a potential means of creating nanostructures with complex structure and function. However, using self-assembly to create nanostructures with long-range order whose size is tunable is challenging, because the kinetics and thermodynamics of protein interactions depend sensitively on solution conditions. Here we systematically investigate the impact of varying soluti...

A thin, insulating layer with high electrical resistivity is vital to achieving high performance of powder magnetic cores. Using layer-by-layer deposition of silica nanosheets or colloidal silica over insulating layers composed of strontium phosphate and boron oxide, we succeeded in fabricating insulating layers with high electrical resistivity on iron powder particles, which were subsequently ...

Two dimensional Co 2 Se 3 nanosheet simultaneously possesses out-of-plane electric polarization, ferromagnetism, half-metallic transportation and piezoelectricity, rendering it a promising candidate for advanced multiferroic applications.

ZnO nanostructures have been synthesized by a simple reflux method, using different ionic liquids, such as 1-benzyl-3-methylimidazolium bromide ([BzMIM][Br]), 1,1'-(1,4 phenylenebis (methylene)) bis (3-methyl-1H-imidazol-3-ium) bromide ([MM-1,4-DBzIM2][Br]2) and 1-phenacyl-3-methylimidazolium bromide ([PMIM][Br]), with different amount of sodium hydroxide in water. Als...

We propose a 'weaving' evolution mechanism, by systematically investigating the products obtained in controlled experiments, to demonstrate the formation of Ni-based 'microflowers' which consists of multiple characteristic dimensions, in which the three dimensional (3D) NiO 'microflower' is constructed by a two-dimensional (2D) nanosheet framework that is derived from weaving one-dimensional (1...

Ln(3+) (Ln = Tb, Eu) doped zinc phosphate tetrahydrate (ZPT:Ln(3+)) and ammonium zinc phosphate (AZP:Ln(3+)) nano-/micro-structured materials were synthesized in aqueous solution without the addition of any structure-directing agent. The phase structures, morphologies and luminescence properties of the as-synthesized samples were investigated by X-ray diffraction (XRD), scanning electron micros...

A novel amperometric nitrite (NO2 − ) sensor was developed based on immobilization of hemoglobin (Hb) on a graphene nanosheet modified electrode by chitosan-N, N-Dimethylformamide (CS-DMF) hydrogel. The surface morphologies of the modified electrode were characterized by SEM, and direct electrochemistry of Hb on the graphene nanosheet-based electrode were investigated by cyclic voltammetry. The...

We report on a synthetic approach to produce self-supported flexible surface-enhanced Raman scattering (SERS) active membranes consisting of polyamide (PA) nanofibers grafted with vertical Ag-nanosheets, via a combinatorial process of electrospinning PA-nanofiber membranes, assembling Au-nanoparticles on the PA-nanofibers as seeds for subsequent growth of Ag-nanosheets, and electrodepositing Ag...

ZnO nanosheets are a relatively new form of nanostructure and have demonstrated potential as gas-sensing devices and dye sensitised solar cells. For integration into other devices, and when used as gas sensors, the nanosheets are often heated. Here we study the effect of vacuum annealing on the electrical transport properties of ZnO nanosheets in order to understand the role of heating in devic...
