Mechanical energy harvesting based on triboelectric effect has been proven to be a simple, cost-effective, and robust method for electricity generation. In this study, we developed a rationally designed triboelectric nanogenerator (TENG) by utilizing the contact electrification between a polytetrafluoroethylene (PTFE) thin film and a layer of TiO2 nanomaterial (nanowire and nanosheet) array. Th...

This paper reports the preparation and characterization of the coupling of aryl halides with arylboronic acids using a new nanomaterial catalyst Ni(5%): ZnS synthesized in the aqueous phase. The X-ray diffraction (XRD) analysis shows the formation of the cubic zinc blende phase, with a particle size of about 3 nm confirmed by high resolution transmission electron microscopy with a high catalyti...

Herein, we evaluated the use of paper towel, waxed paper, and Parafilm M® (Heathrow Scientific, Vernon Hills, IL, USA) as alternative substrates for screen-printed sensor manufacturing. Morphological study was performed to evaluate the adhesion of the ink on these uncommon substrates, as well as the morphology of the working electrode. The electrochemical characterization was carried out using ...

The aggravating effects of zero-dimensional, particle-shaped nanomaterials on allergic asthma have been previously investigated, but similar possible effects of one-dimensional shaped nanomaterials have not been reported. More importantly, there are no available means to counteract the adverse nanomaterial effects to allow for their safe use. In this study, an ovalbumin (OVA)-sensitized rat ast...

A W-containing inorganic-organic nanohybrid with a plate-like morphology has been successfully prepared through a nonaqueous synthetic route using WCl(6) as the tungsten source and benzyl alcohol as the solvent. The as-prepared hybrid nanomaterial was used directly as an efficient precursor for the formation of WO(3) nanoplates via a simple thermal treatment process. The as-obtained WO(3) mater...
