We show herein that Pt-modified carbon-titanium dioxide cathode nanocomposite matrices (designated hereafter as Pt/C-TiO2), prepared by heterogeneous photocatalysis, afford facile electrocatalytic reduction of carbon dioxide to methanol and isopropanol. Pyridinium cation was used as a solution co-catalyst in this study. The electrocatalytic activity of the new-generation Pt/C-TiO2 cathodes was quantitatively mapped by the combined use of rotating disk electrode voltammetry along with gas chromatography assay of the reduction products in solution.

We demonstrate a novel metal stanogermanide contact metallization process for high mobility germanium-tin (GeSn) channel MOSFETs. The multi-phase nickel-platinum stanogermanide [Ni(GeSn)+Ptx(GeSn)y] contacts are formed by reacting Ni-Pt alloy with Ge0.947Sn0.053 alloy, which is epitaxially grown on Ge (100) substrate by solid source molecular beam epitaxy (MBE). Compared with nickel stanogermanide [Ni(GeSn)] contacts, the Pt-incorporated contacts, i.e. [Ni(GeSn)+Ptx(GeSn)y], exhibit enhanced thermal stability in a wide range of formation temperatures and have superior surface morphology even after thermal processing. The proposed contacts are attractive for the integration in high mobility GeSn MOSFETs.

We investigated the formation of metal and dielectric liners in via holes. We obtained a conformal deposition of the Ag metal and PVPh liners in Si deep via holes. The measured Ag liner thickness increased from 0.18 μ mt o 1.44μm as the radius of the via hole was increased from 0.85 μ mt o 5μm. We also obtained a conformal deposition of the PVPh dielectric liner of about 830 nm in thickness in 10 μm deep via holes. The Ag metal and PVPh dielectric liners had uniform thickness on every region of their respective deep via holes.

A novel symmetric RuO2/RuO2 supercapacitor with a high operating voltage of 1.6 V is built using the nanocrystalline hydrous RuO2. The symmetric supercapacitor exhibits an energy density of 18.77 Wh kg −1 at a power density of 500 W kg −1 based on the total mass of active electrode material and excellent cycling stability and power capability. These results demonstrate the potentialities of using RuO2 for symmetric supercapacitor or using RuO2 as negative electrode for asymmetric supercapacitor with high energy density.
