- 2017Titanate nanotubes and nanosheets as a mechanical reinforcement of water-soluble polyamic acid: Experimental and theoretical studies ; Titanate nanosheets (TiNS), titanate nanotubes (TiNT), and scrolled titanate nanosheets (STiNS) were used to synthesise polymer nanocomposites by solution processing. The hardness was found to increase by 90% on addition of 2% TiNS while the modulus (Er) increased by 103% compared to the pure polymer. Small angle X-ray scattering (SAXS) measurements of composite films were used to study alignment of nanostructures within the polymer. The obtained data on mechanical properties of composites have been tested against theoretical values and it was established that both nanostructures alignment as well as their mechanical properties affect the hardness and modulus of the polymer composites. At a low content of TiNS, the reinforcement behaviour matched well with Halpin-Tsai theory which assumes the filler has unidirectional orientation. After addition of 2 wt% TiNT, the hardness and modulus of the polyamic acid salt composites increased by 91% and 165%, respectively, and were higher than theoretical predictions, indicating that both TiNT and STiNS, prepared by hydrothermal synthesis, may have higher mechanical properties than bulk TiO2. At a high filler loading (>2 wt%), the mechanical properties of composites do not fit established theories due to agglomeration of titanate nanostructures.citations

Mass-transfer measurements at porous 3D Pt-Ir/Ti electrodes in a direct borohydride fuel cell
Abstract
The volumetric mass-transport coefficients (kmAe) for borohydride ion oxidation at various titanium 3D electrode structures in a rectangular flow channel were calculated by chronoamperometry in a three-electrode electrochemical flow cell. The 3D electrodes used for the oxidation of borohydride in alkaline media included flat, mesh, micromesh, fine mesh and felt coated with a Pt-Ir alloy catalysts. Felt, fine mesh and micromesh electrodes showed high electrochemical activity with current enhancement factors () of 100, 64, 22, respectively at a mean linear flow velocity of 6 cm s-1 through the electrodes. In the presence of a turbulence promoter (TP), the currents from the flat and mesh electrodes improved twice compared with no TP. The 3D electrodes were tested in a complete cell with an anolyte consisting of 2.5 mol dm-3 NaBH4 in 2 mol dm-3 and a catholyte of 0.75 mol dm-3 H2O2 in 2 mol dm-3 NaOH. The power density increased in the following order: plate < micromesh < mesh < felt < mesh + 1 TP < fine mesh. The maximum power density at the fine mesh was 44.5 mW cm-2 at a cell potential of 0.44 V and a current density of 100 mA cm-2 at 296 K.
