    摘要: A positive electrode for use in alkaline rechargeable electrochemical cells comprising: a material comprising a compositionally and structurally disordered multiphase nickel hydroxide host matrix which includes at least one modifier chosen from the group consisting of F, Li, Na, K, Mg, Ba, La, Se, Nd, Pr, Y, Co, Al, Cr, Mn, Fe, Cu, Zn, Sc, Sn, Sb, Te, Bi, Ru, and Pb. A process for forming a high loading uniformly distributed multiphase substantially nitrate free sintered positive electrode for use in an alkaline rechargeable electrochemical cell, the process comprising: (1) fabricating sintered electrode material by forming a slurry of nickel powder, water, carboxymethylcellulose binder, methyl cellulose binder, and a poly(ethylene oxide) polymer; spreading the slurry on a preoxidized perforated nickel substrate; drying the slurry; and sintering the slurry; (2) impregnating the sintered electrode material using multiple impregnation cycles to attain high loading, where each impregnation cycle comprises the steps of: placing the sintered electrode material on a rack; dipping the rack into nickel nitrate; allowing the rack to drip dry; dipping the dried rack into NaOH solution; spraying the rack in a first tank with deionized water overflowing from a second tank; dipping the rack in the second tank filled with deionized water overflowing from a third tank; dipping the rack in the third tank filling with deionized water at a rate of 8-10 gpm; drying the rack; and flipping the rack to attain uniform deposition of material; where in the median dip cycle and in the final dip cycle of the multiple impregnation cycles, the step of dipping the rack into nickel nitrate is replaced by a step of dipping the rack into cobalt nitrate to produce an enriched cobalt surface; and (3) forming the impregnated sinter into positive electrode material by presoaking the impregnated sinter in NaOH presoak tanks to substantially eliminate nitrates; brushing the presoaked impregnated sinter in a surface brushing station; charging the brushed impregnated sinter; discharging the charged impregnated sinter; rinsing the discharged impregnated sinter; and drying the rinsed impregnated sinter to complete the formation of positive electrode material.

    摘要: A first aspect of the present invention is an improved microwave vacuum feed-through device for coupling microwave energy from a microwave wave guide in a substantially atmospheric pressure region into an elongated linear microwave applicator in a sub-atmospheric pressure region. The improved feed-through is designed to match the impedance of the microwave wave guide in the atmospheric pressure region and the improved linear microwave applicator. A second aspect of the present invention is an improved linear microwave applicator for uniformly coupling 95% or more of the microwave energy input thereto into an elongated plasma zone. The applicator includes curved microwave reflector panels which are used to tune the uniformity of the radiated microwave energy along the length of the linear applicator. A third aspect of the present invention is a microwave enhanced chemical vapor deposition method for depositing thin film material. The method includes a step of intensifying the kinetic/thermal energy of the electrically neutral species in the plasma by intensifying the kinetic/thermal energy of the ions in the plasma and thereby, through ion-neutral collisions, intensifying the kinetic/thermal energy of the electrically neutral species. The step of intensifying the kinetic/thermal energy of the ions in the plasma includes subjecting the plasma to either a very low frequency alternating current electrical bias or an alternating polarity magnetic field, the frequency of thereof being less than about 100 kHz.

    摘要: Disclosed herein is a solid state, directly overwritable, non-volatile, high density, low cost, low energy, high speed, readily manufacturable, single cell memory element having reduced switching current requirements and an increased thermal stability of data retention. The memory element includes a volume of memory material which is a transition metal modified chalcogen. The transition metal may be selected from the group consisting of Nb, Pd, Pt and mixtures or alloys thereof. The memory material may further include at least one transition metal selected from the group consisting of Fe, Cr, Ni and mixtures or alloys thereof. The memory element exhibits orders of magnitude higher switching speeds at remarkably reduced switching energy levels. The novel memory element of the instant invention is in turn characterized, inter alia, by at least two stable and non-volatile detectable configurations of local atomic and/or electronic order, which configurations can be selectively and repeatably accessed by electrical input signals of designated energy levels. The memory elements are further characterized by enhanced thermal stability of data retention, which stability is achieved by elementally modifying Te--Ge--Sb semiconductor material from which previous memory elements were fabricated.
