An electrolyzer cell is disclosed which includes a cathode to reduce an oxygen-containing molecule, such as H2O, CO2, or a combination thereof, to produce an oxygen ion and a fuel molecule, such as H2, CO, or a combination thereof. An electrolyte is coupled to the cathode to transport the oxygen ion to an anode. The anode is coupled to the electrolyte to receive the oxygen ion and produce oxygen gas therewith. In one embodiment, the anode may be fabricated to include an electron-conducting phase having a perovskite crystalline structure or structure similar thereto. This perovskite may have a chemical formula of substantially (Pr(1-x)Lax)(z-y)A′yBO(3-∂), wherein 0<x<1, 0≦y≦0.5, and 0.8≦z≦1.1. In another embodiment, the cathode includes an electron-conducting phase that contains nickel oxide intermixed with magnesium oxide.

A frozen aerated confection comprising an ice structuring protein (ISP) and a hydrophobin is provided.

The invention relates to an electroplating pretreatment method for plastic parts for electroplating, and belongs to the technical field of plastic material treatment. The method comprises the steps that a plastic part for electroplating is fixed to a receiving pole of an electrostatic spinning device, and a polymer solution or melt forms nano-scale fiber through the electrostatic spinning device to be deposited on the surface of the plastic product, so that an electrospun film layer with a large number of submicron-order holes is formed on the surface of the plastic part. Compared with the prior art, the proper surface hole structure is given to the plastic part to be plated through the electrostatic spinning technology, so that the plastic part treated through the method can obtain the surface appearance where metal can be deposited without roughening, and can be put on a line for directly conducting sensitization, activation and electroplating.

The invention relates to a heat treatment method of promoting precipitation of nano-scale carbide in W-containing alloy steel. The heat treatment method is charaterized by comprising the following steps of soaking a steel billet for 24-48h under the condition with the temperature being 1100-1200 DEG C, and performing cooling along with a furnace to a room temperature; performing austenitizing for20-40min under the condition with the temperature being 850-1000 DEG C, and performing quenching in ice salt water; performing heating to 650-750 DEG C under the condition with the vacuum degree being10<-3>-10<-2>Pa and the magnetic field intensity being 10-14T and at a speed of 3-7 DEG C / min, keeping isothermy for 0.5-3.0h, and cooling to the room temperature, wherein the steel billet is prepared from the following chemical components: 0.06-0.14wt% of C, 1.50-3.00wt% of W, smaller than 0.01wt% of P, smaller than 0.005wt% of S and the balance of Fe and inevitable impurities, and the temperature of the ice salt water is 3 DEG C below zero to 1 DEG C below zero. The heat treatment method provided by the invention is simple in technology, low in cost and short in production period; and the strength of the W-containing alloy steel subjected to treatment with the method is obviously improved.
