Electronic shell effects and the stability of alkali nanowires [PDF]

, 2004
Experimental conductance histograms for Na nanowires are analyzed in detail and compared to recent theoretical results on the stability of cylindrical and elliptical nanowires, using the free-electron model.

Synthesis and Magnetic Properties of NiCo Nanowire Array by Potentiostatic Electrodeposition

International Journal of Electrochemical Science, 2014
NiCo alloy nanowires have been fabricated by electrodeposition using anodized aluminum oxide templates. Growth of nanowires consists of four different stages namely nucleation, steady state growth, filling of pores, and coverage of filled nanowires on ...

Do Twin Boundaries Always Strengthen Metal Nanowires?

Nanoscale Research Letters, 2008
It has been widely reported that twin boundaries strengthen nanowires regardless of their morphology—that is, the strength of nanowires goes up as twin spacing goes down.

Fluctuational Instabilities of Alkali and Noble Metal Nanowires

, 2004
We introduce a continuum approach to studying the lifetimes of monovalent metal nanowires. By modelling the thermal fluctuations of cylindrical nanowires through the use of stochastic Ginzburg-Landau classical field theories, we construct a self ...

Achieving thermally conductive low loss PVDF-based dielectric composites via surface functionalization and orientation of SiC nanowires

eXPRESS Polymer Letters, 2020
Semi-conductive silicon carbide (SiC) nanowires were amino-functionalized to achieve better dispersion in poly(vinylidene fluoride) (PVDF) matrix. It was found that PVDF based composites with amino-functionalized SiC (f-SiC) nanowires exhibited lower ...

Piezoresistive Monitoring of Carbon Nanomaterial‐Reinforced Epoxy Composites Under Cyclic and Fatigue Loading: A Review

Advanced Engineering Materials, EarlyView.
Carbon nanomaterial‐reinforced epoxy composites exhibit pronounced piezoresistive behavior, enabling intrinsic damage sensing under cyclic and fatigue loading. This review critically compares carbon nanotube and graphene systems, correlating filler content, percolation threshold, and gauge factor with sensing stability and damage evolution.

Stability of Spinmotive Force in Perpendicularly Magnetized Nanowires under High Magnetic Fields

, 2012
Spinmotive force induced by domain wall motion in perpendicularly magnetized nanowires is numerically demonstrated. We show that using nanowires with large magnetic anisotropy can lead to a high stability of spinmotive force under strong magnetic fields.
