Claim 0:
1. A method comprising:
depositing a fluid into a reservoir of a device, the device comprising:
a first layer having a top surface and a bottom surface opposite and spaced apart from the top surface;
a second layer having a top surface and a bottom surface opposite and spaced apart from the top surface;
the second layer comprising a first cavity, a set of second cavities, and a set of grooves; wherein the first cavity perforates the second layer from the top surface to the bottom surface; wherein each of the second cavities perforates the second layer from the top surface to the bottom surface;
wherein each of the grooves extends from the first cavity to one of the second cavities on the bottom surface; wherein the second layer is disposed on the first layer, such that the bottom surface of the second layer is disposed on the top surface of the first layer; wherein the first cavity together with the top surface of the first layer defines the reservoir; wherein the set of second cavities together with the top surface of the first layer defines a set of receptacles; and wherein the set of grooves together with the top surface of the first layer define a set of conduits fluidly connecting each of the receptacles to the reservoir;

such that, when the fluid is placed in the reservoir, the fluid flows to each of the receptacles via capillary action, such that the fluid at least partially fills each of the receptacles;
wherein the fluid comprises an alkali metal precursor and a solvent.
