  • Graphene quantum dots (GQDs) were synthesized and incorporated with polyethylene dioxythiophene:poly(4-styrenesulfonate (PEDOT:PSS), Ag nanowires (AgNWs) to form a composite that can be used for enhancement of relative humidity (RH%) sensing. The composite films contained bulk heterojunctions of AgNW/GQD and AgNW/PEDOT:PSS. The sensors made from the composites responded well to relative humidity in a range from 10% to 50% at room temperature.

  • TiO2 nanowires doped with different amounts of Ni2+ ions (from 0 to 18 mol%) were synthesized by hydrothermal technique. The samples were characterized by X-ray diffraction (XRD) and Raman spectroscopy, field emission scanning electron microscopy (FESEM), and diffuse reflection spectroscopy. The XRD analysis showed that the doped samples exhibit anatase single phase. The lattice parameters remain unchanged, independent on Ni2+ content.

  • The magnetic properties in CoNiP/Au multisegments nanowire were investigated. All the samples were prepared by electrodeposition method with pH of 5.5 and room temperature. The electrochemical potential of CoNiP was determined by cycle voltammetary. The crystalline structure and morphology of the samples were characterized by X-ray diffraction (XRD), Scanning Electron Miroscopy (SEM) and High-resolution transmission electron microscopy (HRTEM), respectively.

  • Nanowires can be defined as structures with thicknesses or diameters of tens of nanometers or less and unconstrained lengths. Many different types of nanowires exist, including metallic (e.g., Ni, Pt, Au or different alloys based on metals), semiconducting (e.g., Si, InP, GaN, etc.), insulating (e.g., SiO2, TiO2), and molecular nanowires (e.g. organic DNA or inorganic). Nanowires have many interesting properties that are not seen in bulk or 3-D materials.

  • There are two basic approaches of synthesizing nanowires: top-down and bottom-up pproach. In a top-down approach a large piece of material is cut down to small pieces hrough different means such as lithography and electrophoresis. In a bottom-up approach he nanowire is synthesized by the combination of constituent ad-atoms. Most of the ynthesis techniques nowadays are based on bottom-up approaches.
