A Novel Shape Memory Behavior of Single-crystalline Metal Nanowires
… memory effect and pseudoelastic behavior of single-crystalline FCC metal (Cu, Ni, and Au) nanowires are discovered. Specifically, upon tensile loading and unloading, these wires can recover elongations of up to 50%, well beyond the recoverable strains of 5-8% typical for most bulk shape …

EXPERIMENTAL STUDIES OF QUANTUM OSCILLATIONS IN THE TRANSVERSE MAGNETORESISTANCE OF SINGLE-CRYSTALLINE, ULTRAPURE MAGNESIUM: NON-OHMIC EFFECTS.
We report here the observation of non-ohmic behavior in the dominant oscillatory component (the cigar component) of ρ('H) in ultrapure magnesium when the magnetic field, 'H, is parallel to [0001] and the current density, 'J, lies in the basal plane. In order to study this new phenomenon …

Fabrication and characterisation of copper nanowires electrochemically deposited in etched ion-track membranes
Poly- and single-crystalline copper nanowires have been created by electrochemical deposition of copper in etched ion-track membranes. 30 µm thick polycarbonate foils were irradiated at the UNILAC (GSI, Darmstadt) with Au and Pb ions of kinetic energy 1-2 GeV with ?uences between 1 and 10^9 …

Synthesis, structure and magnetic properties of nanowires and films by electrodeposition
… used for the fabrication of metallic nanowires. Single crystalline Ni, Co, and Fe wires have been successfully fabricated and the mechanisms of the single crystalline wire growth have been investigated in detail. It shows that the strain/stress during electrodeposition is attributed to the highly …
