TL;DR: In this paper, composites with improved uniformity and dispersion can be formed using chemically functionalized carbon nanotubes, and a significant enhancement of the mechanical properties was obtained at low nanotube loading.

TL;DR: An electrophoretic process to fabricate composite CNT films with controlled nanotube orientation and surface density, and enhanced adhesion is developed and the cathodes have significantly enhanced macroscopic field emission current density and long-term stability under high operating voltages.

TL;DR: In this paper, a dielectrophoresis method was proposed to manipulate, align, and assemble 1D nanostructures using alternating current (AC) electric field, where pre-formed CNTs dispersed in water are assembled into microelectrodes and sub-microme-ter diameter fibrils with variable lengths from ~ 1 lm to over 1 cm.

TL;DR: In this article, a method for depositing a nanostructure-containing material onto an object or substrate includes one or more of the following: forming a solution or suspension of nanostructures, selectively adding "chargers" to the solution, immersing electrodes (410, 430) in the solution and applying a direct and/or alternating current electrical field between the two electrodes for a certain period of time.

TL;DR: In this article , carbon nanotubes (CNTs) were incorporated into pure Al and a high-strength Al alloy via the same powder metallurgy route, which led to a better dispersion state of CNTs in powders and composites of pure Al.
