SYNTHESIS OFFE 2O3-C COMPOSITE NANOFIBERS

3.3.3 Media for PEI crystallization
By taking advantage of methanol being a good solvent for dissolving crystalline PEI at room temperature, we developed the strategy to generate shaped silicas by using methanol as a mediator to adjust the programmed self-assembly of crystalline PEI (Jin &Yu[r]

In this chapter we focus on the electrochemical and adsorption properties of carbon nanofibers prepared by catalytic chemical vapour deposition (CCVD) method, underlying the results obtained by the authors.
We first present some of up to date literature concerning the CVD synthesis<[r]

The present paper reveals the synthesis of polyaniline, polyaniline nanoparticles and polyaniline composite. Improvement of polyaniline properties can be achieved either by forming composites and nanocomposites of aniline, or blends with commercially available polymers or inorganic materials which o[r]

In spite of those potential advantages of the nanoreinforced adhesives, the incorporation of nanofillers into the adhesive may originate problems associated to the increase in viscosity and the modification of the wetting behaviour with regard to the neat adhesive. It is[r]

The specific magnetization curves of the calcined MgFe 2 O 4 /PVP composite nanofibers obtained from room temperature VSM measurement are shown in Fig. 8 . These
curves are typical for a soft magnetic material and indicate hysteresis ferromagnetism in the field range of ± 500[r]

The increase in TMC and PIP concentrations lead to increasing the As(V) rejection, while the TMC concentration is dominant to an increment of the thickness of the synthesized membrane. Thus, the permeability of the membrane decreases more significantly with an increase in TMC concentration. The PIP[r]

In a previous investigation [ 14 ], manganese dioxide nanofibers were prepared by a chemical precipitation method and utilized for the fabrication of composite manganese dioxide—MWCNT films by electrophoretic deposition. The composite films deposited on stainless steel foils sho[r]

In our study, we use small angle light scattering as a primary tool to investigate dispersion of nanofibers. The dispersion efficiency was determined using a low-angle light scattering photometer–a Micromeritics Saturn Digitizer (www.micromeritics.com). Light scattering data are reported i[r]

dye-sensitized solar cells. Titania nanotubes have been obtained by treating anatase or rutile struc- ture TiO 2 with NaOH at 120°C, and subsequent washing with HCl solution [69,70]. The resulting titania nanotubes (nanoscrolls) are 50 to 200 nm long and their diameter is about 10 nm[r]

Bououdina et al., 2006 presented a review on hydrogen absorbing materials. The hydrogen is theoretically adsorbed on the surface of CNFs and then incorporated between the graphitic sheets. The structure of CNFs allows the physisorption of large amounts of hydrogen. The used catalyst was unsupport[r]

For the iteration with k configurations, we would like to identify the k-way partitioning solution with the optimal net performance gain. Unfortunately, temporal and spatial par- titioning are again dependent on each other due to the reconfiguration cost. To break this cycle, we apply a heuristic te[r]

• Many clays are aluminosilicates, which have a sheet-like (layered) structure, and consist of silica SiO 4 tetrahedra
bonded to alumina AlO 6 octahedra in a variety of ways. A 2:1 ratio of the tetrahedra to the octahedra results in smectite clays, the most common of which is montmorilloni[r]
