Carbon nanotubes can also enable shorter processing times and higher energy efficiencies during composite curing with the use of carbon nanotube structured heaters. Autoclaving is the ‘gold standard’ for composite curing however, it comes at a high price and introduces part size limitations.
The NIOSH Manual of Analytical Methods includes guidance on electron microscopy of filter samples of carbon nanotubes and nanofibers, [29] and additionally some NIOSH methods developed for other chemicals can be used for off-line analysis of nanomaterials, including their morphology and geometry, elemental carbon content (relevant for carbon ...
NIST SRM 2483 is a soot of single-wall carbon nanotubes used as a reference material for elemental analysis, and was characterized using thermogravimetric analysis, prompt gamma activation analysis, induced neutron activation analysis, inductively coupled plasma mass spectroscopy, resonant Raman scattering, UV-visible-near infrared fluorescence ...
A review of works on fullerene toxicity by Lalwani et al. found little evidence that C 60 is toxic. [1] The toxicity of these carbon nanoparticles varies with dose, duration, type (e.g., C 60, C 70, M@C 60, M@C 82), functional groups used to water-solubilize these nanoparticles (e.g., OH, COOH), and method of administration (e.g., intravenous, intraperitoneal).
Ultrablack materials, made up of “forests” of carbon nanotubes, are important in space, where there is more light than is convenient to work with. Ultrablack material can be applied to camera and telescope systems to decrease the amount of light and allow for more detailed images to be captured. [6]
Polysaccharides have been successfully been used to modify carbon nanotubes forming stable hybrids. [48] To make carbon nanotubes soluble in water, phospholipids such as lysoglycerophospholipids have been used. [49] The single phospholipid tail wraps around the carbon nanotube, but the double tailed phospholipids did not have the same ability.
Nanoparticles can be divided into combustion-derived nanoparticles (like diesel soot), manufactured nanoparticles like carbon nanotubes and naturally occurring nanoparticles from volcanic eruptions, atmospheric chemistry etc. Typical nanoparticles that have been studied are titanium dioxide, alumina, zinc oxide, carbon black, carbon nanotubes ...
Because of their tube structure, carbon nanotubes can be made with or without end caps, meaning that without end caps the inside where the drug is held would be more accessible. Right now with carbon nanotube drug delivery systems, problems arise like the lack of solubility, clumping occurrences, and half-life. [8]
