Abstract: Carbon doped TiO2—Bronze nanostructures, preferably nanowires were synthesized via a facile doping mechanism and were exploited as active material for Li-ion batteries. Both the wire geometry and the presence of carbon doping contribute to high electrochemical performance of these materials. Direct carbon doping for example reduces the Li-ion diffusion length and improves the electrical conductivity of the wires, as demonstrated by cycling experiments, which evidenced remarkably higher capacities and superior rate capability over the undoped nanowires. The as prepared carbon-doped nanowires, evaluated in lithium half-cells, exhibited lithium storage capacity of ˜306 mA h g−1 (91% of the theoretical capacity) at the current rate of 0.1C as well as excellent discharge capacity of ˜160 mAh g−1 even at the current rate of 10C after 1000 charge/discharge cycles.

Abstract: A microfluidic device comprises a lower layer that is electrically conductive and transparent with respect to an incident optical beam, an upper layer, comprising first portions that are electrically conductive and second portions that are electrically insulating, adjacent and alternated to the first ones; a compartment interposed between the lower layer and the upper layer seamlessly extending between the lower layer and the upper layer; the compartment contains a filler medium that is transparent with respect to the incident optical beam and markers dispersed in the filler medium; the markers are electrically charged and are adapted to move inside the compartment in all directions in variable amounts according to the intensity of the electrical signal applied and to emit an optical emission beam when lit by an incident optical beam.

Abstract: A microfluidic device comprises electrically conductive lower portions, transparent to an incident optical beam; first upper portions electrically conductive and configured to receive an electrical signal; shielding portions opaque to the incident optical beam and arranged between the first upper portions and the lower portions, the shielding portions having one or more through openings; one or more compartments containing a filler means and markers dispersed in filler means. Each compartment comprises at least one lower chamber and at least one upper chamber in fluid communication with each other via said one or more through openings. Each lower chamber extends between a respective through opening and the lower portions and each upper chamber extends between at least one respective through opening and the first upper portions. The markers are electrically charged and are configured to move between an upper chamber and one or more lower chambers in variable amounts according to the intensity of the electric signal applied to one or more upper portions and to emit an optical emission beam when illuminated in the lower chamber by the incident optical beam.
