  In this work,copper/palladium (Cu/Pd) multilayer nanowires were successfully prepared by electrodeposition method using polycarbonate template. The fabrication of Pd/Cu multilayer nanowires was controlled by analyzing the current–time transient during electrodeposition using potentiostat. The morphological properties of the nanowires were studied by scanning electron microscopy (SEM) and resu...

A bioanode for glucose based biofuel cell have been fabricated by combining glucose oxidase and highly ordered Palladium (Pd) nanowire array electrode. The Pd nanowires were 5.57 μm in length and 64.28 nm in diameter. The hydrogel composite modified Pd nanowire array bioanodes were characterized with cyclic voltammetry in the presence of different scan rates and different substrate concentratio...

Palladium (Pd) is considered as ideal hydrogen sensing material due to its properties as high sensitivity and selectivity to hydrogen gas, fast response and reversible room temperature operation.Silicon nanowire (SiNW) functionalized with Pd based hydrogen gas nanowire sensor having quantum confinement effect and high sensitivity because of high surface to volume ratio of SiNW. This paper highl...

A facile one-pot approach for preparing hierarchical nanowire-networks of hollow polymer@Pd nanospheres is reported. First, polymer@Pd hollow nanospheres were produced through metal-complexation-induced phase separation with functionalized graft copolymers and subsequent self-assembly of PdNPs. The nanospheres hierarchically assembled into the nanowire-network upon drying. The Pd nanowire-netwo...

We analyze theoretically the formation of stretched Pd-nanowires and their interaction with hydrogen. In our approach, we simulate the nanowire stretching process using a first-principles molecular-dynamics method to obtain realistic atomic geometries of the contact in its final stages before the nanowire breaks. The electrical conductance of the nanowire is also calculated at each point of the...

While bulk palladium is non-magnetic, several recent studies have shown that magnetism can occur in hcp Pd films, fcc twinned Pd nanoparticles, and Pd atomic strands. These studies show that small changes in Pd atomic configurations can induce magnetic properties. This raises the question of whether nanoscale Pd structures in general are magnetic. In this work, we examine coaxial palladium nano...

Thin films of SnO2 nanowires were successfully prepared by using chemical vapor deposition (CVD) process on quartz substrates. Afterwards, a thin  layer of palladium (Pd) as a catalyst was coated on top of nanowires. For the deposition of Pd, a simple and low cost technique of spray pyrolysis was employed, which caused an intensive enhancement on the sensing response of fabricated sensors...

Interest in nanowire technology has grown significantly over the past several years, due to their potentially broad applications in optics, electronics, and sensors (e.g., resonators, molecular detection, nanoconnectors, biosensors, and gas sensors). Due to their small size, sensitivity, real-time detection, and ultra-low power demands, nanowire sensors are being investigated for detection of a...
