Synthesis of Ag–Ni core–shell nanowires and their application in anisotropic transparent conductive films

Abstract

Transparent conductive films with high anisotropic conductivity ratio (>105) were prepared from Ag–Ni core–shell nanowires by applying a magnetic field.

Magneto-piezoresistivity in iron particle-filled silicone: An alternative outlook for reading magnetic field intensity and direction

“…Since polymer wires with diameter of 100-200 nm have been already produced [22], as well as iron nanoparticles assembly could maintain magnetic stability down to size of 10-20 nm [23], even if its realization is complex, in principle it is not to be excluded that the miniaturization of the MPR sensitive core, described in this paper, can achieve similar functionality.…”

“…The main objective of this paper is to establish, by means of some basic experiments in the millimeter scale range, that the MPR effect can be used to detect the change of magnetic polarization direction at a magnetization intensity similar to that produced by the semi-permanent nanomagnets of a magnetic memory. It does not seem easy to produce samples MPR through the nanowires by keeping the used magnetic interaction between nano-particles of iron in it, but there are some encouraging data in the literature [22,23]. Nevertheless, the methodology, and operation principles of the sensor proposed here, are very promising and intriguing, and can constitute a basic step to open new perspectives in the field of magnetic reading heads with competitive performance and costs in comparison with standard GMR spin valve.…”

Electrical anisotropy and multidimensional pressure sensor of aligned Fe3O4@silver nanowire/polyaniline composite films under an extremely low magnetic field

“…Anisotropic electrical conductivities have been observed in aligned lms, meshes, and nanopapers fabricated by different methods. The comparison of electrical anisotropy in the present study with literature 4,8,9,18,19,24,25,39,[52][53][54][55][56][57][58] is presented in Table 1. It is clear that the electrical anisotropy and electrical conductivity have an inverse relationship.…”

“…The anisotropic properties of these nanomaterials are strongly dependent on the structure of their assemblies. Various advanced functional materials such as transparent lms, 9,10 thermal conductive lms, 11,12 ion-exchange membranes 13 and liquid-crystalline lms, 14 have been fabricated based on anisotropic nanostructures such as arrays, sheets and ropes. These anisotropic nanostructures were constructed via various methods, such as external electrical/magnetic eldassisted fabrication, 3,7 chemical-vapor-deposition-grown method, 12,15 self-assembly, 8,16 electro-synthesis, 17 mechanical shear 4 like stretching, 18 spinning 19 and extrusion, 20 thermal press 21 and annealing.…”

Salt-mediated polyol synthesis of silver nanowires in a continuous-flow tubular reactor

“…Each batch produces only a small AgNW amount. Even for the high-concentration synthesis, the yield is only 0.5-1 g each time, [32][33][34] restricted to meet the growing AgNW requirements.…”
