    摘要: A detector for generating an electrical current that is proportional to a flux of neutrons includes a neutron sensitive emitter, a conductive collector, an insulator between the neutron-sensitive emitter and the collector, an electrical connection to the neutron sensitive emitter, and an electrical connection to the conductive collector. The neutron sensitive emitter includes an emitter material with no more than 2 stable isotopes, and which upon impact by a neutron having an energy of from 100 keV to 1000 keV will generate electrons in proportion to the flux of neutrons in less than 10 minutes, and any generated electrons not generated in less than 10 minutes will be generated in no less than 30 days. A method of detecting neutrons generated by a nuclear reactor is also disclosed.

    摘要: Polyphase wireless power transfer systems are provided. The transfer system may be used for charging hybrid and electric vehicles. The systems are capable of transferring over 50 KW over an air gap of 15 cm. The systems use a rotating magnetic field to transfer power. The system may comprise transmitter coil assembly. The coil assembly may be one or more layers. The system may employ either unipolar or bipolar coils. The transmitter also comprises compensating capacitance connected in series with at least one coil for each phase. A value of the compensating capacitance for each phase is determined such that the transmitter has at least two independently excitable resonant modes at a resonant frequency. The transmitter is compatible with a plurality of different receivers including three-phase, single phase with a circular coil and single phase with DD coils.

    摘要: A method of binder jet additive manufacturing (BJAM) is provided. The method includes feeding a supply of powder particles to a powder bed, delivering an organic binder onto the powder bed in select locations of each layer to form a porous green part, and introducing to the binder a secondary component that chemically reacts with the binder to form a solid polymer matrix around the powder particles. The secondary component is introduced either by: (i) infiltration of the secondary component into the porous green part; or (ii) by combining the secondary component with the powder particles prior to feeding the powder particles to the powder bed. A binder system for BJAM is also provided. The binder system includes a reactive pair including an organic binder that is capable of being deposited on a powder bed; and a secondary component that is reactive with the organic binder.
