Multicomponent and multifunctional hybrid structures based on microsized carbon fibers sheathed with aligned carbon nanotubes and their derivatives have been successfully prepared, and have been demonstrated to be an effective means for connecting nanoscale entities to the outside world and to possess interesting electrochemical properties attractive for a wide range of potential applications, including in methanol direct fuel cells and highly sensitive biological and chemical sensors. Judicious modification of the carbon-fiber-supported aligned carbon nanotubes with various functional moieties could lead to a class of novel multidimensional, multicomponent, and multifunctional materials of practical significance.

Estradiol treatment of cardiac allograft recipients abolishes MHC class II antigen expression in the coronary arteries and decreases macrophage infiltration in all three layers of the vessel wall, whereas T-lymphocyte infiltration is decreased only in the myointima. These findings are associated with estradiol inhibition of myointimal proliferation. Thus, estradiol treatment may have a beneficial effect on graft arteriosclerosis through immune mechanisms.

The nanoscale TiO2 was synthesized and their electrochemical properties as the anode electrode materials for rechargeable Li-ion batteries were measured. The structure, morphology and electrochemical properties of the nanoscale TiO2 composites synthesized were characterized in detail by X-ray (XRD), Transmission Electron Microscopy (TEM) and electrochemical measurement. The first discharge capacities were 126 mAh/g for the nanoscale TiO2 at the current density of 100 mA/g at ambient temperatures. The specific capacities were stabilized at around 57mAh/g after 20 cycles.
