The mechanical properties including elastic stiffness constants as well as bulk modulus of Palladium (Pd) nanowire were calculated in the constant temperature and pressure (NPT), ensemble by molecular dynamics (MD) simulation technique. The quantum Sutton-Chen (Q-SC) many-body potential was used to calculate the cohesive energy as well as forces experience by every atoms. The temperature and pr...

ZnO nanowire inorganic/organic hybrid ultraviolet (UV) light-emitting diodes (LEDs) have attracted considerable attention as they not only combine the high flexibility of polymers with the structural and chemical stability of inorganic nanostructures but also have a higher light extraction efficiency than thin film structures. However, up to date, the external quantum efficiency of UV LED based...

There is evidence to support the claim that speedbreakers can cause accidents and injury. When a vehicle approaches a speed-breaker at a speed greater than some threshold velocity, the risk of accident or injury is substantial. Speed-breakers are inconspicuous in low visibility conditions, like at night, or when there is fog, rain or snow. This problem is particularly acute in developing countr...

Zinc oxide (ZnO) nanogenerators have attracted increasing interest in the scientific community for use energy harvesting and mechanical sensing applications. Understanding interplay between piezoelectricity semiconductor physics is fundamental to enhancing these devices’ performances, although direct characterization at nanoscale challenging. With this work, we present a new strategy improve pi...

We report a method to suppress streaming potential using an Ag-coated microfluidic channel on a p-type silicon nanowire (SiNW) array measured by a multiplexed electrical readout. The metal layer sets a constant electrical potential along the microfluidic channel for a given reference electrode voltage regardless of the flow velocity. Without the Ag layer, the magnitude and sign of the surface p...

Using an Al-foil of thickness ≈ 18 μ m as a substrate and electrode, a piezoelectric nanogenerator (NG) that is super-fl exible in responding to the wavy motion of a very light wind is fabricated using ZnO nanowire arrays. The NG is used to harvest the energy from a waving fl ag, demonstrating its high fl exibility and excellent conformability to be integrated into fabric. The NG is applied to ...

Magnetic domain-wall motion driven by a voltage dissipates much less heat than by a current, but none of the existing reports have achieved speeds exceeding 100 m/s. Here phase-field and finite-element simulations were combined to study the dynamics of strain-mediated voltage-driven magnetic domain-wall motion in curved nanowires. Using a ring-shaped, rough-edged magnetic nanowire on top of a p...

Because of their unique mechanical and electrical properties, zinc oxide (ZnO) nanowires are used widely in microscopic nanoscopic devices structures, but characterizing them remains challenging.

A one-dimensional first-order beam model obtained through integration across its section. Based on model, theoretical analysis carried out for cantilever PSC nanowire subjected to time-harmonic transverse shear force. The effects bending vibrat...

Harvesting energy from multiple sources available in our personal and daily environments is highly desirable, not only for powering personal electronics, but also for future implantable sensor-transmitter devices for biomedical and healthcare applications. Here we present a hybrid energy scavenging device for potential in vivo applications. The hybrid device consists of a piezoelectric poly(vin...
