Abstract WO3-TiO2 heterostructural nanofibers (HNFs) were prepared by a simple spin coating method. The structures, chemical constitutions and morphologies of the samples characterized various kinds techniques, including XRD, XPS, EDX, BET, SEM TEM. results suggested that WO3 nanoparticles with size range 20–30 nm decorated uniformly on surface TiO2 in composite thin films. XPS confirmed existe...

In this paper, we present our research on left hand gesture acquisition and analysis in guitar performances. The main goal of our research is the study of expressiveness. Here, we focus on a detection model for the left hand fingering based on gesture information. We use a capacitive sensor to capture fingering positions and we look for a prototypical description of the most common fingering po...

thin films of sno2 nanowires were successfully prepared by using chemical vapor deposition (cvd) process on quartz substrates. afterwards, a thin  layer of palladium (pd) as a catalyst was coated on top of nanowires. for the deposition of pd, a simple and low cost technique of spray pyrolysis was employed, which caused an intensive enhancement on the sensing response of fabricated sensors. prep...

Graphene has been demonstrated as a potential gas sensor material by many researches [1,2]. However, the strong binding energy between graphene and analyte molecules leads to an inefficient desorption and subsequently a poor reliability on sensing performance. Besides, the lack of semiconducting property of graphene also disables the modulation of the transport characteristics through light irr...
