Title: Formation of potassium tantalate niobate thin films by metalorganic deposition
Inventor: MICHELI ADOLPH L
IPC: C07F9/00
Filed: 1991-05-08
Abstract: FORMATION OF POTASSIUM TANTALATE NIOBATE THIN FILMS BY METALORGANIC DEPOSITION          Abstract of the Disclosure Thin films of potassium tantalum niobate, KTa1-xNbxO3, or KTN, material are deposited using the non-vacuum technique of metalorganic deposition. First, a suitable metalorganic precursor dissolved in solution, preferably the carboxylates of potassium, tantalum and niobium in xylene, is dispensed onto a substrate much like photoresist.  The substrate, preferably platinum or platinum coated yttria but also foreseeably CaF2, BaF2 or Er2O3, is spun at a few thousand revolutions per minute to remove the excess fluid, driving off the xylene solvent and uniformly coating the substrate surface with a metalorganic film a few microns thick.  The soft metalorganic film is then pyrolyzed in an air atmosphere to convert the metalorganic precursors to their constituent oxides, and subsequently annealed to form the perovskite crystal structure throughout the film.  Superior films are formed when the metalorganic precursor solution is potassium deficient as compared to stoichiometry, and then subsequently annealed after pyrolysis in a potassium rich environment to form stoichiometric metal oxide films.  The resulting films exhibit uniform, high quality physical, chemical and electrical properties throughout, and are suitable for the economical fabrication of an uncooled infrared detector having maximum response characteristics.

Title: Generation of hybrid genes and proteins by virus-mediated recombination
Inventor: GRITZ LINDA R
IPC: C12N15/48
Filed: 1991-10-22
Abstract: (54)Title: GENERATION OF HYBRID GENES AND PROTEINS BY VIRUS-MEDIATED RECOMBINATlON            (57) Abstract The ability of viruses to undergo recombi-nation within tandemly arranged homologous se-quenecs can be utilized to generate chimeric gen-es and proteins. Tandemly arranged homologous sequences will rapidly degenerate in a random fashion to yieid a single copy comprised of por-tions of both original sequences. Therefore, a rec-                     ombinant virus which contains two related but non-identical genes in tandem array yields a pop-ulation of recombinant viruses which  contain a spectrum of hybrid sequences derived from rec-ombination between the original genes. The vi-ruses, therefore, contain hybrid DNA sequences that encode proteins with new epitopes or differ-ent combinations of epitopes. Vaccines are de-rived which may afford protection against a broad spectrum of antigen types.
