1. Comparative study of carbon nanotube dispersion using surfactants Aqueous carbon nanotube dispersions were obtained by sonication tip using two cationic (DTAB and CTAB) and three anionic surfactants (SDDBS, SDS and SC). UV-Vis spectroscopy is a versatile method for characterizing the dispersion quality of CNTs in a solution. Bundles of MWCNTs are not active in the wavelength region between 2...

Multi-walled carbon nanotubes are dispersed in water via the formation of adducts with dyes, where the process may be monitored by the visual observation of colour variations of dye solutions. Atomic force microscopy images corroborate evidence for attachment of dyes on nanotubes. Laser Raman and Fourier transform infrared spectroscopies suggest intimate electronic interactions between nanotube...

in this paper, synthesized (raw) multi-walled carbon nanotube (rmwcnts) surfaces were modified with chitosan and β-cyclodextrin using chen’s soft cutting technique. raw and surface modified multi-walled carbon nanotubes were observed by transmission electron microscope (tem). the results showed that chitosan and β-cyclodextrin could attach to the outer surface of nanotubes, wrapping the nanotub...

Background: As one of the representative protein materials, nanocages (PNCs) are self-assembled supramolecular structures with multiple advantages, such as good monodispersity, biocompatibility, structural addressability, and facile production. Precise quantitative functionalization is essential to construction PNCs designed purposes. Results: With three modifiable interfaces, int...

toluene and benzene were eliminated using multi-walled carbon nanotubes (mwcnts). in order to investigate influence of acid treatment on the mwcnts adsorption capacities, the mwcnts were functionalized by nitric acid (10 m) under reflux conditions for 2 h. fourier transform infrared (ftir) and raman spectroscopy were employed to confirm the formation of functional groups on the nanotubes surfac...

C-H functionalization is a very active research field that has attracted the interest of scientists from many disciplines. This Outlook describes the collaborative efforts within the NSF CCI Center for Selective C-H Functionalization (CCHF) to develop catalyst-controlled selective methods to enhance the synthetic potential of C-H functionalization.

Metal nanoparticles are being extensively used in various biomedical applications due to their small size to volume ratio and extensive thermal stability. Gold nanoparticles (GNPs) are an obvious choice due to their amenability of synthesis and functionalization, less toxicity and ease of detection. The present review focuses on various methods of functionalization of GNPs and their application...
