Concrete is the most used construction material in world; however, its deficiency shrinkage and low tensile resistance undeniable. Used as secondary reinforcement, fibers can modify concrete properties various ways. Carbon-fiber-reinforced highly suitable to maintain longevity of infrastructure where corrosion steel shorten useful service life structure while polypropylene mostly improve concre...

Smart multi-walled carbon nanotube (MWCNT)-coated cellulose fibers with a unique sensing ability were manufactured by a simple dip coating process. The formation of electrically-conducting MWCNT networks on cellulose monoand multi-filament fiber surfaces was confirmed by electrical resistance measurements and visualized by scanning electron microscopy. The interaction between MWCNT networks and...

We present a novel, low-cost approach to fabricate flexible piezoelectric nanogenerators (NGs) consisting of ZnO nanowires (NWs) on carbon fibers and foldable Au-coated ZnO NWs on paper. By using such designed structure of the NGs, the radial ZnO NWs on a cylindrical fiber can be utilized fully and the electric output of NG is improved. The electric output behavior of the NGs can be optionally ...

Dual-coated optical fibers provide easier stripping and less sensitivity to micro-bending. Despite a record of success in the field, dual-coated fibers can still pose a challenge within the manufacturing environment since they are susceptible to developing physical anomalies during processing and fiber-handling. Although these anomalies are believed to be benign, there are very few published re...

Carbon nanomaterials are advantageous as electrodes for neurotransmitter detection, but the difficulty of nanomaterials deposition on electrode substrates limits the reproducibility and future applications. In this study, we used plasma enhanced chemical vapor deposition (PECVD) to directly grow a thin layer of carbon nanospikes (CNS) on cylindrical metal substrates. No catalyst is required and...

A green, environmental friendly and sensitive method for determination of volatile organohalogen compounds was described in this paper. The method is based on a homemade sol-gel single-walled carbon nanotube/silica composite coated solid-phase microextraction to develop for sampling and analysis of Carbon tetrachloride, Benzotrichloride, Chloromethyl methyl ether and Trichloroethylene in air. A...

We report a coaxial fiber supercapacitor, which consists of carbon microfiber bundles coated with multiwalled carbon nanotubes as a core electrode and carbon nanofiber paper as an outer electrode. The ratio of electrode volumes was determined by a half-cell test of each electrode. The capacitance reached 6.3 mF cm(-1) (86.8 mF cm(-2)) at a core electrode diameter of 230 μm and the measured ener...
