Allgemeine Beschreibung

Multi walled carbon nanotubes (MWNTs, CNTs) were prepared by chemical vapor deposition (CVD). In chemical vapor deposition (CVD), a volatile precursor undergoes thermal decomposition at elevated temperatures to form a solid deposit on a substrate. Compared to other techniques, CVD produces greater yield of carbon nanotubes. Morphology and structure of the nanotubes can be easily tuned using CVD technique. The CNTs formed can be formed in bundles over a catalyst support or in patterns over substrates.1

3D Printing of Carbon Fiber-Reinforced Composites

3D printing is a type of additive manufacturing that can be used to rapidly fabricate components with highly customizable geometries.

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.
