چکیده

Carbon-based nanostructures are currently one of the hottest research topics in science for producing innovative materials, composites, and electronic devices. The ability of carbon to exist in different allotropic forms has provided a variety of nanoscale size shapes with fascinating properties (i.e. fullerene, single and multi-walled carbon nanotubes, carbon fibers, carbon nano-onions, carbon nanohorns). Among this wide diversity of carbon nanomaterials, the unique electronic, physicochemical and mechanical properties of carbon nanotubes (CNTs) render them ideal candidates for molecular scale electronic applications.[1] In this context, chemical functionalization is an especially attractive goal as it can improve solubility and processability of CNTs and allows the unique properties of CNTs to be coupled to those of other materials.[2] With the long term objective of constructing versatile and functional nanosized ensembles for photoinduced electron transfer, we recently embarked on the preparation of donor-acceptor nanohybrids consisting of carbon nanotube units endowed with tetrathiafulvalene (TTF) or πextended tetrathiafulvalene (exTTF) electron-donor moieties following different, covalent and non-covalent, approaches (Figure 1).[3] Synthetic, spectroscopic and electrochemical results on these new nanostructures will be presented and discussed, along with photophysical properties of some of the aggregates formed.

4th World Congress on Biomimetic, Artificial Muscles and Nano-Bio Life Time of Trilayer Actuators Based on Polypyrrole

Artificial muscles based on polypyrrole films doped with ClO4 had demonstrated movements up to 180 degrees in LiClO4 aqueous solution which are controlled through the applied electrical current. Movements of this type are achieved with currents from 10 mA. The current density and its polarity control the rate and the movement ́s direction of the artificial muscle[1, 2]. Besides, bilayer and tril...

Linkage of doxycycline onto functionalized multi-walled carbon nanotube and morphological characterization

In this paper functionalized multiwall carbon nanotubes (FMWCNT) were modified using doxycycline, containing reactable nitrogen, which can attach chemically to functionalized MWCNT. The synthesized nano compounds were characterized by Fourier transform infrared spectroscopy (FT-IR) and Raman spectroscopy. These spectrums proved the existence of nitrogen atoms of amide functional groups. The mor...
