Allgemeine Beschreibung

Structure of double walled carbon nanotubes (DWNTs) can be imagined as a two coaxial concentric single walled carbon nanotubes (SWNTs). It has been prepared by catalytic chemical vapor deposition. DWNTs exhibit excellent field emission properties and may be potentially useful as field emission displays (FEDs) and field emission transistors (FETs).

Boron Nitride Nanotubes: Properties, Synthesis and Applications

Boron nitride nanotubes (BNNT) are close structural analogs of carbon nanotubes (CNT), which are high aspect ratio nanotubular material, where carbon atoms are alternately substituted by nitrogen and boron atoms.

Sorting Carbon Nanotubes and Their Biological Applications

Carbon nanotubes (CNTs) have received much attention since their discovery in 1991 by Sumio lijima1 due to their excellent mechanical, electrical, and optical properties.

3D Printable Conductive Nanocomposites of PLA and Multi-walled Carbon Nanotubes

A nanocomposite is typically defined as a mixture between a host material (e.g., polymer matrix) and nanofillers with at least one dimension of less than 100 nm.

Graphene Nanoribbons: Production and Applications

Graphene is a one-atomic-layer thick two-dimensional material made of carbon atoms arranged in a honeycomb structure. Its fascinating electrical, optical, and mechanical properties ignited enormous interdisciplinary interest from the physics, chemistry, and materials science fields.
