摘要： A metal-semiconductor-metal (MSM) photodetector, specifically a new, improved low noise device is disclosed. The disclosed device is a MSM photodiode in which the cathode and anode are made of different materials with optimal Schottky barrier heights. One of these materials is chosen to provide a high ratio of Schottky barrier height to hole transport and the other to provide a high ratio of Schottky barrier height to electron transport. The disclosed MSM photodetector is designed to allow each Schottky barrier to be individually optimized to the point that a wide bandgap Schottky barrier enhancement layer and its associated heterointerface may become unnecessary. Elimination of the charge buildup at the heterointerface enhances carrier extraction resulting in photodetectors with elevated quantum efficiency and enhanced bandwidths.

摘要： A double tunnel junction is disclosed that can be used as a magnetic sensor or as random access memories. The preferred embodiment comprises three magnetic metal materials separated by two insulating layers. A current is passed through the first tunnel junction thereby developing a voltage in the second junction. The resistance of this device can be changed over a 100% when an external magnetic field of just a few gauss is applied.

摘要： A water-resistant polyphenolic protein adhesive has been obtained from the Atlantic ribbed mussel, Geukensia (Modiolus) demissa. This protein provides a natural model for synthetic or bioengineered adhesives and is characterized by a Gly-Tyr-Lys or, more frequently, Gly-Dop-Lys "tail" fragment of a repeating octapeptide or nonapeptide unit. A complete octapeptide or nonapeptide unit (including both the 5- or 6-amino acid residue "head" as well as the 3-residue "tail") can be represented as follows:[Gln]Glu].sub.x -Thr/Ala-Gly-Dop/Tyr-Y.sup.1 -Y.sup.2 -Gly-Tyr/Dop-Lyswhere x is zero or one,Y.sup.1 is Val, Leu, Asp or Ser, andY.sup.2 is Ala, Pro, Hyp, or Leu.The tripeptide "tail" and/or the 5- or 6-residue "head" of the polypeptide is useful as a single unit (curable with difunctional crosslinkers or the like) or as a repeating unit.

摘要： An aerodynamic nozzle for aerosol particle beam formation into a vacuum comprises a tubular column having a first stage section with a plurality of spaced aerodynamic lenses therein so that an aerosol entering the inlet end of the first stage section is formed into a beam of generally aligned particles. The beam exits the first stage section through an outlet orifice into a second stage section also having a plurality of spaced aerodynamic lenses to maintain the aerosol in its beam form. The beam then exists through a nozzle to an orifice at the discharge end of the second stage section into an evacuated region. The pressure decreases from the first stage (which is preferably at atmospheric pressure) to the second stage to the evacuated region.

摘要： The present invention relates to an improved catalyst for the selective synthesis of monomethylamine (MMA) and dimethylamine (DMA) at the expense of trimethylamine (TMA) for a starting feed of methanol and/or dimethyl ether and ammonia. The current industrial catalyst for this process is a standard SiO.sub.2 /Al.sub.2 O.sub.3 material. The present invention combines this standard catalyst with microporous carbon molecular sieves (CMS) to form a composite material (i.e., a CMS/SiO.sub.2 /Al.sub.2 O.sub.3 material) with higher selectivity for the desired products MMA and DMA. The invention also relates to methods of making the improved catalyst and a process of using the improved catalyst material in the production of MMA and DMA.

摘要： In an ion cyclotron resonance mass spectrometer, ion cyclotron resonance signals at higher harmonics of cyclotron frequency are employed to increase the resolution of ICR mass spectrometer without increasing the magnetic field. The detection electrodes consist of M (where M is an integer) identical electrodes arranged in M-fold symmetry about the axis of the coherent cyclotron motion of the observed ions. In an ion cyclotron having four points of voltage in space, the cyclotron electrodes are set up in clockwise symmetric fashion. To increase the resolution in signal detection resulting from the potential induced by ions moving in orbits in the specrometer, the first and third voltages are added and the second and fourth voltages are subtracted from the sum of the first and third voltages.
