  • Publication number: 20080049379
    Abstract: A novel lead zirconium titanate (PZT) material having unique properties and application for PZT thin film capacitors and ferroelectric capacitor structures, e.g., FeRAMs, employing such thin film material. The PZT material is scalable, being dimensionally scalable, pulse length scalable and/or E-field scalable in character, and is useful for ferroelectric capacitors over a wide range of thicknesses, e.g., from about 20 nanometers to about 150 nanometers, and a range of lateral dimensions extending to as low as 0.15 ?m. Corresponding capacitor areas (i.e., lateral scaling) in a preferred embodiment are in the range of from about 104 to about 10?2 ?m. The scalable PZT material of the invention may be formed by liquid delivery MOCVD, without PZT film modification techniques such as acceptor doping or use of film modifiers (e.g., Nb, Ta, La, Sr, Ca and the like).

  • Patent number: 7312202
    Abstract: The present invention relates to chemically synthesized promoters that circumvent the disadvantages of the universal CMV promoter/enhancer elements. The promoter may be used in a variety of applications, particularly in genetic immunization. The chemically synthesized promoter overcomes the common problems of the CMV promoter element such as: low transgene expression levels, transient expression, and the large amount of plasmid DNA needed for intramuscular injection in subjects.

  • Publication number: 20060108623
    Abstract: A method of preventing oxygen deficiency in a ferroelectric or high ? film material having a top electrode layer deposited thereon. Process conditions are employed that either enable the top electrode layer to be formed without oxygen abstraction from the ferroelectric or high ? film material in the vicinity and at the top surface thereof, or else provide the ferroelectric or high ? film material in the vicinity and at the top surface thereof with a surplus of oxygen. In the latter case, the deposition formation of the top electrode layer on the ferroelectric or high ? film material depletes the over-stoichiometric excess of the oxygen in the film material, to yield a device structure including an electrode on a film material having a proper stoichiometry, e.g., of PbZrTiO3.

  • Publication number: 20050058626
    Abstract: A general method for vaccinating against any pathogen is presented. The method utilizes expression library immunization, where an animal is inoculated with an expression library constructed from fragmented genomic DNA of the pathogen. All potential epitopes of the pathogen's proteins are encoded in its DNA, and genetic immunization is used to directly introduce one or more expression library clones to the immune system, producing an immune response to the encoded protein. Inoculation of expression libraries representing portions of the Mycoplasma pulmonis genome was shown to protect mice from subsequent challenge by this natural pathogen. Protection against Listeria was also obtained using the method.

  • Publication number: 20040170616
    Abstract: A method of transferring a gene to vertebrate cells is disclosed. The method comprises the steps of: (a) providing microprojectiles, the microprojectiles carrying polynucleic acid sequences, the sequences comprising, in the 5′ to 3′ direction, a regulatory sequence operable in the tissue cells and a gene positioned downstream of the regulatory sequence and under the transcriptional control thereof; and (b) accelerating the microprojectiles at the cells, with the microprojectiles contacting the cells at a speed sufficient to penetrate the cells and deposit the polynucleic acid sequences therein. Preferably, the target cells reside in situ in the animal subject when they are transformed. Preferred target cells are dermis or hypodermis cells, and preferred genes for insertion into the target cells are genes which code for proteins or peptides which produce a physiological response in the animal subject.
