Single suspended carbon nanofibers on carbon micro-structures were fabricated by directed electrospinning and subsequent pyrolysis at 900 C of carbon nanotube/polyacrylonitrile (CNT/PAN) composite material. The electrical conductivity of the nanofibers was measured at different weight fractions of CNTs. It was found that the conductivity increased almost two orders of magnitude upon adding 0.5 ...

The ionic conductivity of LiSO3CF3 complexed with wax-like solids of the general form H-(CH2)32 (CH2CH2O)10-H were investigated. The conductivity of the waxes studied in this work should be dependent on the shape of the domains. Conductivity measurements were made perpendicular, σ⊥, and parallel, σ, to the direction of molecular orientation. Depending on the size of the conducting domains, an...

The objective of this experiment was to measure the apparent total tract digestibility (ATTD) and the retention rate of Zn, Cu, Mn, and Fe in pigs fed either inorganic or organic sources of Zn, Cu, Mn, and Fe. The experimental design was a randomized complete block design with a 2 × 3 factorial arrangement of treatments. There were 2 types of diets (corn grits-based or corn-soybean meal [SBM]-b...

in this paper electrical conductivity measurements and optical investigations takes place in aot/ heptane/ (water or aqueous) systems. the water in oil system prepared with adding water in 50% by weight of aot/ heptane solution.  in other systems instead of water, aqueous solutions of 1) zinc acetate and water 2) potassium hydroxide and water were used. in each phase, the trend of the electrica...

Nanosized TiO2 particles were prepared by sol–gel method. The TiO2 particles were co-deposited with chromium using electrodeposition technique. In investigating of coating surfaces by scanning electron microscope (SEM), the results showed that the morphology of the coating surface was changed by adding TiO2 nanoparticles to the chromium coating. The corrosion behavior of the coatings was assess...

Metal-organic frameworks (MOFs) have recently attracted much interest in electrochemical fields due to their controlled porosity, large internal surface area, and countless structural topologies. However, the direct application of single component MOFs is limited since they also exhibit poor electronic conductivity, low mechanical stability, and inferior electrocatalytic ability. To overcome th...

Asthmatics are known to react to inhaled hyperosmolar solution. Therefore, the effect of hyperosmolar salt solutions on tight junctions of the airway epithelium was investigated by electron microscopy. Rat trachea was perfused with different concentrations of sodium chloride (NaCl) and then fixed from the luminal side with glutaraldehyde to which the electron dense tracer lanthanum chloride had...

Submitted for the MAR13 Meeting of The American Physical Society Numerical studies of non-Drude ac-conductivity and infrared magneto-optics in (Ga,Mn)As HUAWEI GAO, JAIRO SINOVA, Department of Physics, Texas A&M University — Optical absorption experiments on (III,Mn)V diluted magnetic semiconductors (DMS’s) show that the ac-conductivity has nonDrude behavior at low frequency. STM study show man...
