Abstract: Disclosed are electrolyte compositions for electrochemical devices, where the electrolyte compositions comprise a microemulsion and where the microemulsion comprises an aqueous phase and a water-immiscible phase. Also disclosed are microemulsion electrolyte compositions for electrically rechargeable electrochemical energy storage devices, including ion batteries (such as lithium ion, sodium ion, magnesium ion, calcium ion, and aluminium ion batteries), redox flow batteries and supercapacitors.

Abstract: Disclosed are a cathode materials suitable for an aluminium ion battery, wherein the cathode materials comprise a main group element nitride, and an oxide of a main group element or an oxide of a element in Group 1 to 13. The nitride is preferably a 2-dimensional layered material. Preferably, the ratio of the main group element nitride to the oxide is between 5:95 and 95:5 (by weight).

Abstract: A microfluidic device for measuring an amount of an oxidant in a solution is disclosed. The device includes a microfluidic substrate configured to mix a solution sample to be analysed with an indicator dye solution containing an indicator dye under conditions suitable for some of the indicator dye to react with any oxidant in the solution to produce an oxidant measurement solution having a reduced indicator dye concentration that is indicative of the amount of oxidant in the solution, the microfluidic substrate including an optical reading window through which the reduced indicator dye concentration in the oxidant measurement solution can be measured optically.

Abstract: A method for the production of hydrocarbon(s), such as methane, substituted hydrocarbons, such as methanol, or the production of hydrogen, the method comprising the steps of contacting a first catalyst with water in order to photocatalyse the splitting of at least some of the water into hydrogen and oxygen; and contacting a second catalyst with a gas stream comprising carbon dioxide and at least some of the hydrogen produced from step (a) in order to photocatalyse the reaction between the hydrogen and carbon dioxide to produce hydrocarbon(s), such as methane, and/or substituted hydrocarbons, such as methanol. In an embodiment, the catalyst comprises gold and or ruthenium nanoclusters supported on a substrate.
