Title: Method and system for the combination of non-thermal plasma and metal/metal oxide doped y-alumina catalysts for diesel engine exhaust aftertreatment system
Inventor: CHANDA ASHOK
IPC: F01N3/08
Filed: 2001-07-26
Abstract: The present disclosure pertains to a system and method for treatment of oxygen rich exhaust and more specifically to a method and system that combines non-thermal plasma with a metal doped Y-alumina catalyst. Current catalyst systems for the treatment of oxygen rich exhaust are capable of achieving only approximately 7 to 12% NO x reduction as a passive system and only 25-40% reduction when a supplemental hydrocarbon reductant is injected into the exhaust stream. It has been found that treatment of an oxygen rich exhaust initially with a non-thermal plasma and followed by subsequent treatment with a metal doped Y-alumina prepared by the sol gel method is capable of increasing the NO x reduction to a level of approximately 90% in the absence of SO2 and 80% in the presence of 20 ppm of SO2. Especially useful metals have been found to be indium, gallium, and tin.

Title: Electrochemical cell having an electrode with a dicarbonate additive in the electrode active mixture
Inventor: TAKEUCHI ESTHER S
IPC: H01M4/06
Filed: 2001-10-23
Abstract: An electrochemical cell of either a primary or a secondary chemistry, is described. In either case, the cell has a negative electrode of lithium or of an anode material which is capable of intercalating and de-intercalating lithium coupled with a positive electrode of a cathode active material. A discarbonate compound is mixed with either the anode material or the cathode active material prior to contact with its current collector. The resulting electrode couple is activated by a nonaqueous electrolyte. The electrolyte flows into and throughout the electrodes causing the dicarbonate additive to dissolve in the electrolyte. The dicarbonate solute is then able to contact the lithium to provide an electrically insulating and ionically conducting passivation layer thereon.

Filed: 2000-08-14
Abstract: An isolated DNA of SEQ ID NO: 1 is provided that encodes the transcription factor BP1, which is believed to be a repressor of the .beta.-globin gene. A  host cell that is transformed with a vector that contains the DNA may be used to produce BP1. Vectors having a controllable promoter operably connected to the BP1 open reading frame may be used to transform .beta.-globin producing cells of patients with sickle cell anemia, thereby providing a treatment.  Because BP1 is overexpressed in leukemia and breast cancer cells,acute myeloid leukemia, acute lymphocytic leukemia, and breast cancer can be screened for and diagnosed by determining whether PB1is overexpressed in cell samples of patients who may have theseconditions. An antisense DNA or RNA to the DNA  encoding BP1 may be used as a treatment for acute myeloid leukemia, acute lymphocytic leukemia, and breast cancer.

Patent CA-2389740-A1 (CA)
Inventor: KNIGHTS SHANNA D
IPC: H01M8/10
Filed: 2000-08-23
Abstract: In a solid polymer fuel cell series, various circumstances can result in a fuel cell being driven into voltage reversal. For instance, cell voltage reversal can occur if that cell receives an inadequate supply of fuel. In order to pass current, reactions other than fuel oxidation may take place at the fuel cell anode, including water electrolysis and oxidation of anode components. The latter may result in significant degradation of the anode, particularly if the anode employs a carbon black supported catalyst. Such fuel cells can be made more tolerant to cell reversal by using higher catalyst loading or coverage on the anode catalyst support or a more oxidation resistant anode catalyst support, such as a more graphitic carbon or Ti4O7.

Inventor: SEZIN NINA
IPC: C25D13/02
Filed: 2000-10-25
Abstract: An improved method for depositing ferroelectric particles on a surface of a substrate to form films or stand-alone bodies. The improvement is based on electrophoretic deposition (EPD) of ferroelectric films by using a tri-functional phosphate ester additive having a concentration less than 10 volume percent in the EPD suspension, without the need for addition of a binder. The method includes preparation of the suspension by washing and dispersing ferroelectric particles, for example, commercially available PZT powder, in a polar solvent such as ethanol, followed by addition of the phosphate ester additive to the suspension, and an ultrasound treatment. The suspension is used in EPD of the ferroelectric particles on a prepared substrate. Following EPD, the green film is dried and sintered at high temperature. Visual and physical examination of stand alone and patterned PZT deposited films show excellent quality obtained in manufacturing a diversity of piezoelectric products, featuring exceptionally high green film uniformity, thickness distribution, and reproducibility to within .plusmn. 2 microns for 20 micrometer film thickness. The phosphate ester additive functions by improving stabilization and control of suspension characteristics and properties during the electrophoretic migration process, and by improving desired dimensions, characteristics, and electrical properties of the deposited green film. Thin or thick ferroelectric films, either as stand alone products, or formed on geometrically demanding patterned or non-patterned substrates are produced by using the method. The improved method is applicable to different ferroelectric particulate materials and to different substrates used for manufacturing piezoelectric elements and devices, in a cost effective manner.

Abstract: A hybrid polypeptide composed of an identification peptide and a desired functional protein are produced by recombinant DNA techniques. A DNA expression vector is con-strutted that includes segments of DNA coding for the identification peptide and the de-sired functional protein. The identification peptide consists of a specific sequence of amino acids that has the desired affinity for a non-antibody capture protein. This peptide maybe linked to either the amino or carboxyl terminal of the functional protein. The identification peptide may or may not contain a sequence of amino acids that can be fragmented by se-quence specific proteases or chemical agents to yield the native protein. The hybrid poly-peptide produced by either cell or cell-free based expression systems is now suitable for further processing: This fusion protein can be purified by affinity chromatographic tech-piques using an immobilized non-antibody capture protein that has the desired affinity for the identification peptide: Alternately the capture protein may contain a label that will allow for the tracking of the functional protein in the system being studied.
