A controllable flower-like Au nanostructure array for surface-enhanced Raman scattering (SERS) was fabricated using the combined technique of the top-down approach of conventional photolithography and the bottom-up approach of electrodeposition. Au nanostructures with a mean roughness ranging from 5.1 to 49.6 nm were obtained by adjusting electrodeposition time from 2 to 60 min. The rougher Au ...

Electrodeposition experiments of the charge-transfer complex copper tetracyanoquinodimethane (CuTCNQ) (where TCNQ denotes 7,7',8,8'-tetracyanoquinodimethane) on noble metal electrodes (M=Pt and Au) were optimized in order to produce suitable layers for bipolar resistive switching cross-bar M/CuTCNQ/Al memory cells. Corresponding memories exhibited up to more than 10 000 consecutive write/erase ...

Cu electrodeposition was performed on a cylindrical AZ80 substrate with a U-shaped surface. A uniform deposition of Cu was achieved on an AZ80 electrode via galvanostatic etching, followed by Cu electrodeposition in an eco-friendly alkaline Cu plating bath. Improper wetting and lower rotational speeds of the AZ80 electrode resulted in an uneven Cu deposition at the inner upper site of the U-sha...

Abstract Graphene is a suitable transducer for wearable sensors because of its high conductivity, large specific surface area, flexibility, and other unique considerable features. Using simple, fast galvanic pulse electrodeposition approach, nonenzymatic glucose amperometric electrode was successfully developed based on well-distributed fine Cu nanoparticles anchored the 3D structure laser-indu...

2009 WILEY-VCH Verlag Gmb Considerable research has been carried out on photonic crystals since the concept was introduced in 1987. However, fabrication of high-quality 3D photonic crystals still remains a challenge. Among a wide range of proposed techniques, creation of large-area, defect-free 3D polymeric templates through multibeam interference lithography, direct laser writing, or direct in...

Monodisperse crystalline zero-valent iron, iron-nickel, iron-palladium nanowires were synthesised using template-directed electrodeposition methods. Prior to nanowire fabrication, alumina nanotemplates with controlled pore structure (e.g. pore diameter and porosity) were fabricated by anodising high purity aluminium foil in sulphuric acid. After fabrication of alumina nanotemplates, iron, iron-...

Highly ordered Ni nanotube and nanowire arrays were fabricated via electrodeposition. The Ni microstructures and the process of the formation were investigated using conventional and high-resolution transmission electron microscope. Herein, we demonstrated the systematic fabrication of Ni nanotube and nanowire arrays and proposed an original growth mechanism. With the different deposition time,...

Hybrid magnetic nanostructures with high coercivity have immense application potential in various fields. Nickel (Ni) electrodeposited inside Cobalt (Co) nanotubes (a new system named Ni @ Co nanorods) were fabricated using a two-step potentiostatic electrodeposition method. Ni @ Co nanorods were crystalline, and they have an average diameter of 150 nm and length of ~15 μm. The X-ray diffractio...
