Sodium-ion batteries (SIBs) are considered a potential replacement for lithium-ion in the area of low-cost large-scale energy storage. Due to its low operating voltage, high capacity, non-toxicity and production cost, titanium dioxide is now among anode materials under investigation shows most promise. However, poor electrical conductivity one main reasons limiting application. Herein, we desig...
A novel titanium dioxide paste based on Pechini sol-gel method and nanocrystalline TiO2 powder has been successfully developed and tested. The paste enables the formation of sponge like structure of the TiO2 layer i.e. highly porous and at the same time well connected TiO2 network. The layers have been used to assemble dye sensitized solar cells (DSSC) with two ruthenium complex based dyes, N71...
Ir(III) dyes used as sensitizers in dye-sensitized solar cells produced quantum yields approaching unity for conversion of absorbed photons to current under simulated air mass 1.0 sunlight, with current production resulting from ligand-to-ligand charge-transfer states, rather than the typical metal-to-ligand charge-transfer states in ruthenium-based cells.
The chemical transformation of carbon dioxide into useful products becomes increasingly important as CO2 levels in the atmosphere continue to rise as a consequence of human activities. In this article we describe the direct hydrogenation of CO2 into formic acid using a homogeneous ruthenium catalyst, in aqueous solution and in dimethyl sulphoxide (DMSO), without any additives. In water, at 40 °...
Symmetry plays a central role in determining the polarization of spin currents induced by electric fields. It also influences how these generate spin-transfer torques magnetic devices. Here we show that an out-of-plane damping-like torque can be generated ruthenium dioxide (RuO2)/permalloy devices when Néel vector collinear antiferromagnet RuO2 is canted relative to sample plane. By measuring c...
Colloidal mesoporous silica (CMS) nanoparticles with a thin titania-enriched outer shell showing a spatially resolved functionality were synthesized by a delayed co-condensation approach. The titaniashell can serve as a selective nucleation site for the growth of nanocrystalline anatase clusters. These fully inorganic pure silica-core titania-enriched shell mesoporous nanoparticles show orthogo...
