ELECTRON DIFFRACTION AND MICROSCOPY OF CARBON NANOTUBES

Keywords Carbon nanotubes Á Nanocomposites ÁPlasma treatments Á Silica Á Silver nanoparticlesIntroductionCarbon nanotube (CNT)/inorganic composites are a newtype of functional materials that gained tremendous interestin recent decades owing to their exceptional optical,mechanica[r]

x/Si(100) have been stud ied suffi ciently. The epi-taxy of germanium on silicon surfaces (100) turned outto follow the Stranski-Krastanow (SK) mechanism [10].The SK model supposes that a uniformly strained film(the wetting layer) grows pseudomorphically on the sub-strate below some thickness[r]

somewhat deformed hexagons inscribed in circles with radii ghoa0 (or ghh.0). Towards the central line these reflexions are sharply terminated at the positions of graphite reflexions, but they are severely streaked along the normal to the tube axis in the sense away from the axis. Mostly the p[r]

walled CNT-modified microelectrodes with low detection limit(0.25 ng mL−1). The current being derived from oxidation of aminoacid residues (tyrosine and tryptophan), it is then dependent onthe presence of these residues in the target sequence. Zhang et al.(2011) described a strat[r]

.Results and discussionsThe crystal structures of the obtained CuO productswere analyzed through the XRD patterns in Figure 1a.All the reflection peaks could be completely indexed aswell-crystalline, monoclinic CuO, which was in goodagreement with literaturevalues(JCPDSfileno.48-1548).[r]

Polypropylene/ maleic anhydride /organic montmorillonite nanocomposites (PP/ MA/ Org-MMT) have been prepared via direct melt intercalation in an internal mixer. Maleic anhydride (MA) was used as a compatibilizer to improve the dispersability of the clay. The structures of nanocomposites have been ch[r]

Conclusions We employed an easy and direct method based on the hot wire technique to measure the thermal conductivity of epoxy nanofluids. We also studied the differences in heat conduction mechanisms using graphene sheets and different types of CNTs analyzing the role
