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...

In this paper, the synthesis of Ag microflowers for use as manipulable and reusable substrates in surface enhanced Raman spectroscopy (SERS) is demonstrated, working with ultra-low volumes of the analyte. Flower-like AgBr crystallites with a growth direction of 〈110〉 were first obtained by thermolysing a complex obtained by the stabilization of (AgCl2)(-) anions with tetraoctylammonium bromide....

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...

Silver microflower arrays constructed by upright nanoplates and attached nanoparticles were fabricated inside a microfluidic channel, thus a robust catalytic microreactor for allowing in situ SERS monitoring was proposed. On-chip catalytic reduction shows that the silver microflowers have high catalytic activity and SERS enhancement.

Cost-effective and high-performance electrode materials for energy storage conversion are essential commercial applications. In this work, the influence of solvent on morphologies [CH3NH3][M(HCOO)3] precursors was studied to design synthesize two-dimensional (2D) porous NiCo2S4 nanosheets with different structures. As an material supercapacitors, Microflower-NiCo2S4 exhibits excellent capacitan...

biocl microflowers were synthesized using bismuth nitrate pentahydrate and sodium chloride by microwave (mw) assisted synthesis method for 23 minutes at 180 w. scanning electron microscopy (sem) studies revealed a unique morphology of flower-like assemblies comprised of nanosheets. the x-ray diffraction (xrd) pattern showed that a highly pure and crystalline phase has been obtained. the energy ...

ZnO nanostructures were manipulated, via a low-temperature solution process, from pure nanorod arrays to complex nanostructures of microflowers on nanorod arrays with adjusted quantities of flowers. We proposed the mechanism of local dissolution-driven growth to rationally discuss the novel growth process. These nanostructures were used as photoanodes in dye-sensitized solar cells. Compared to ...

Intrinsic and dandelion-like microflower nano-rod structures of boron-doped ZnO thin films were synthesized with an ecofriendly cost-effective chemical bath deposition technique from aqueous solution zinc nitrate hexahdyrate [Zn(NO3)2.6H2O] as a precursor boric acid doping solution. The boron concentrations 0.1, 0.3, 0.5, 1.0, 3.0, 5.0, 7.0 by volume. Scanning electron micrographs showed that a...
