A nanoparticle reactor comprises a nucleation and core growth region providing a laminar flow of reactants in which the reactants thermally decompose to produce a supersaturated vapor that nucleates aerosol particles into particle cores. Nozzle(s) turbulently mix a preheated diluent into the heated reactants. The mixed preheated diluent and heated reactants flow into a core densification region where particle growth is quenched, coagulation limited and sufficient thermal energy for densification of the cores of the particles is provided. Nozzles turbulently mix a preheated additional reactant. A jet and chemical injection and layer formation region is used to develop the particle cores.

When attempting to make a lithium ion-switching device such as a high-efficiency, all-solid state, thin film battery the choice of carrier substrate is all important. As such a substrate must withstand a high temperature under an oxidising atmosphere to crystallise certain layers making up the device, the substrate should not oxidise thereby ruling out most metals. The invention now describes a class of ternary alloys of which the oxidation rate is limited and that are useable to produce thin film batteries on. At least one element with a high affinity to oxygen (Al, Mg, Zn or Si) is present in the alloy. The other two metallic elements reduce the growth of the oxide of this first element. In addition the thus formed oxide scale turns out to be an effective barrier to lithium. Surprisingly, the scale shows nanoscopic voids that allow for sufficient electrical contact with the device layers, thereby eliminating the need for a separate current collector. As the ternary alloy can be made in a flexible foil, it can advantageously be used in a roll-to-roll process.

The preparation process of nanometer aggregated zirconia powder for spraying includes: mixing nanometer zirconia powder stabilized with 20-60 nm granularity yttrium oxide and adhesive in the mass ratio of 95:5 to 98:2 and adding pure water of 1-1.3 times the mixture weight to compound slurry; spraying at 110-300 deg.c to form micron level aggregated powder; and final plasma nodulizing or sintering to form compact powder of 40-90 micron granularity and with the nanometer crystal structure maintained. The obtained powder may meet the technological requirement of plasma spraying or flame spraying. The technological process is simple, great in output, safe, reliable, low in cost and suitable for continuous industrial production.

Techniques herein prepare an alloy catalyst using a protective conductive polymer coating. More particularly, an alloy catalyst is prepared by: preparing a platinum catalyst supported on carbon; coating the surface of the platinum catalyst with a conductive polymer; supporting a transition metal salt on the coated catalyst; and heat treating the catalyst on which the transition metal salt is supported. Also, an alloy catalyst may be prepared by: preparing a platinum-transition metal catalyst supported on carbon; coating the surface of the platinum-transition metal catalyst with a conductive polymer; and heat treating the coated catalyst. Accordingly an alloy catalyst with superior dispersity can be prepared by increasing the degree of alloying of the catalyst through heat treatment while preventing the increase of catalyst particle size through carbonization of the conductive polymer. The prepared catalyst may be useful, for example, for a fuel cell electrode.
