    摘要: A method of forming an anode comprising zinc for an alkaline cell. The method involves mixing zinc particles with binders including preferably polyvinylalcohol, surfactant and water to form a wet paste. The wet paste is molded into the near shape of the cell's anode cavity and then heated to evaporate water. A solid porous zinc mass is formed having microscopic void spaces between the zinc particles. The solid mass can be inserted into the cell's anode cavity and aqueous alkaline electrolyte, preferably comprising potassium hydroxide, then added. The solid mass absorbs the aqueous electrolyte and expands to fill the anode cavity to form the final fresh anode. Zinc fibers may be added to increase the structural integrity of the solid mass.

    摘要: A method of improving spatial resolution of a pump-probe terahertz (THz) imaging system for producing an image of an object. The method provides a chopped optical gating beam focused on a semiconductive layer that is either part of the object or a discrete layer placed over the object. The gating beam is focused on a gating pulse focal spot having a diameter effective to cause measurable modulation in transmission of a THz beam through the semiconductive layer when the gating pulse is on as compared to when the gating pulse is off, creating alternating modulated THz beams for detection and processing. Systems for performing the method in transmission and reflection modes are also described.
