• Magnetic 3D nanomaterial (CoNi-N-CNTs/rGO) is fabricated by simple calcination method. CoNi-N-CNTs/rGO realizes coating of cobalt–nickel alloy and doping nitrogen atoms. Pyrrole-N form the strongest BP sorption bonds with nanocomposite DFT computation. Effervescence-enhanced dispersive solid-phase extraction based on nanocomposite. This method provides lower LODs higher precisions for six BPs...

This paper describes a process for the fabrication and positioning of nanowires (of Au, Pd, and conjugated polymers) embedded in thin epoxy slabs. The procedure has four steps: (i) coembedding a thin film of metal or conducting polymer with a thin film of nickel metal (Ni) in epoxy; (ii) sectioning the embedded structures into nanowires with an ultramicrotome ("nanoskiving"); (iii) floating the...

SnO2 nanowires have been prepared using the active carbon reaction with the fine SnO2 powder at low temperature (700 8C). These nanowires show rectangular cross-section, with their widths ranging from 10 to 50 nm. Branched nanowires with definite included angle are also observed in these products. The morphology and microstructure of the single crystalline SnO2 nanowires and the branched nanowi...

The structures of free-standing gold nanowires are studied by using molecular-dynamics-based genetic algorithm simulations. Helical and multiwalled cylindrical structures are found for the thinner nanowires, while bulk-like fcc structures eventually form in the thicker nanowires up to 3 nm in diameter. This noncrystalline-crystalline transition starts from the core region of nanowires. The vibr...

In this study, we synthesis one-dimensional (1D) manganese(III) Schiff base coordination polymer [Mn(Brsalophen)(μ1,3-N3)]n by reaction of MnCl2·6H2O and tetradentate Schiff base ligand Brsalophen at the presence of NaN3 in methanol and characterized by elemental analyses (CHN) and FT-IR spectroscopy. It was used as a new precurs...

We investigate the transport properties of silicon nanowires coated with zinc sulfide nanoparticles. Silicon nanowires were prepared by metal assisted electro-less chemical etching technique. The diameter of nanowires varies from 30 to 300 nm and length was 30 mm. Zinc sulfide nanoparticles having diameter 30 nm were synthesized by co-precipitation method. The nanoparticles were then deposited ...
