Developing high performance hydrogen (H2) sensors is of utmost importance to facilitate the safe usage H2 as alternative source clean and renewable energy. We present an ultra-sensitive sensor operating in air based on electrostatically formed nanowire (EFN) decorated by palladium nanoparticles (Pd NPs). By appropriate tuning various gate voltages EFN, extremely response ∼2 × 106 % (0.8 exposur...

the output of a piezoelectric nanogenerator based on zno nanowire is largely affected by the shape of nanowire. in order to obtain mechanically stable nanogenerator with high performance, the investigation of mechanical and electrical characteristics related to the nanowires and materials used in nanogenerators are of great interest and significance. this paper presents the various behavior of ...

There is an increasing demand for sensors to monitor environmental levels of ultraviolet (UV) radiation and pollutant gases. In this work, an individual nanowire of Pd modified ZnO nanowire (ZnO:Pd NW) was integrated in a nanosensor device for efficient and fast detection of UV light and CH4 gas at room temperature. Crystalline ZnO:Pd nanowire/nanorod arrays were synthesized onto fluorine doped...

Parallel arrays of either Au or Pd nanowires were fabricated on glass substrates via the electrochemical process of lithographically patterned nanowire electrodeposition (LPNE) and then characterized with scanning electron microscopy (SEM) and a series of optical diffraction measurements at 633 nm. Nanowires with widths varying from 25 to 150 nm were electrodeposited onto nanoscale Ni surfaces ...

Current induced spin-orbit torques have been studied in ferromagnetic nanowires made of 20 nm thick Co/Pd multilayers with perpendicular magnetic anisotropy. Using Hall voltage and lock-in measurements, it is found that upon injection of an electric current both in-plane (Slonczewski-like) and perpendicular (fieldlike) torques build up in the nanowire. The torque efficiencies are found to be as...

In this paper, the scattering of a plane monochromatic electromagnetic wave from a nanowire with circular cross-section in the transverse electric (TE) mode is simulated using the well-known Stratton-Chu surface integral equations. For an ordinary dielectric nanowire the refraction phenomenon is nicely simulated. In the case of a plasmonic nanowire no sign of surface plasmon excitation and prop...

Atomically ordered intermetallic compounds (OICs) have aroused remarkable interests for wide applications and are considered as very promising materials electrocatalysis owing to the strict stoichiometry, well-defined atom binding environment, specific crystalline phase. However, tunable synthesis of intermetallics remains a giant challenge. Herein, this study reports preparation Pd-Sn OICs com...

Platinum (Pt) with foreign components has been considered as an effective approach to overcome CO poisoning, enhance the activity and decrease the usage of expensive Pt in fuel cells. In particular, PtFe is one of the superior binary Pt-based nanomaterial electrocatalysts for formic acid oxidation, which exhibits high resistance to CO poisoning and is a potential candidate for CO-tolerant alloy...
