From application perspectives in adsorption, activated carbon fiber (ACF) is by far one of the most important carbon nanoporous materials to be considered. It has great advantages over other commercial porous storage materials. Activated carbon fiber (ACF) is a promising microporous material with a fiber shape and well-defined porous structure. In general, production of ACF can be commercially ...

The historical notion regarding the inability of gold to catalyze reactions has been discarded in view of recent studies, which have clearly demonstrated the high catalytic efficiency of supported nano-gold catalysts. Although nano-Au catalysts are known to catalyze a variety of reactions, the major focus has been on CO oxidation catalysis. In this work we focus on the important aspects related...

A sensing device is modeled and discussed in this paper. The modeling is done by using carbon nanotubes. This carbon nanotube based sensing device makes it possible produce huge amount of nano chips as a disposable cartridge for diagnostic purposes. Modeling of nano-electrode, characterization and electrochemical detection of DNA hybridization is discussed here. The results shows that the impor...

Carbon fibers have multiple potential advantages in developing high-strength biomaterials with a density close to bone for better stress transfer and electrical properties that enhance tissue formation. As a breakthrough example in biomaterials, a 1.5 mm diameter bisphenol-epoxy/carbon-fiber-reinforced composite rod was compared for two weeks in a rat tibia model with a similar 1.5 mm diameter ...

Localized and controlled delivery of chemotherapeutics directly in brain-tumor for prolonged periods may radically improve the prognosis of recurrent glioblastoma. Here, we report a unique method of nanofiber by fiber controlled delivery of anti-cancer drug, Temozolomide, in orthotopic brain-tumor for one month using flexible polymeric nano-implant. A library of drug loaded (20 wt%) electrospun...

Pitch-matrix composites for deicing, electromagnetic shielding and strain sensing have been developed by using carbon fiber (discontinuous) and carbon black as electrically conductive fillers. A composite with carbon fiber (5 vol%) as the sole filler is effective for strain sensing, which functions by the electrical resistivity increasing reversibly with tensile strain. A composite with carbon ...

Cellulose fibers, cell wall fragments and cellulose microfibrils can be used as reinforced materials for biocomposite manufacture. Understanding nano-mechanical properties of those materials will be very useful to show their full theoretical potential. Nanoindentation testing is a technique that determines the mechanical properties of a material in the sub-micron/nano scale. The test involves p...

A fiber’s efficiency in a short-fiber composite can be accurately solved by shear-lag methods, which can account for fiber geometry, an imperfect interface (or interphase), and extend to low volume fractions. Such an analysis was used to evaluate the aspect ratio requirements for singlewalled nanotubes (SWNT) in a polymeric composite and contrast it to conventional fibers. The aspect ratio requ...
