Abstract: The technology relates to a method of preparing a supported molybdenum catalyst, using a simultaneous acid-base mediated ion exchange process and continually monitoring pH, where molybdenum ions are dispersed inside zeolite channels and located in proximity to the acidic aluminum sites. This process leads to high catalytic activity and resistance to deactivation.

Abstract: An antenna for generating electron spin radiation corresponding to a signal from a radio frequency communications device includes a substantially cylindrical conductor, a first spiral-wound flat inductor, a second spiral-wound flat inductor and a reactive element. The first spiral-wound flat inductor is wound in relation to the second spiral-wound flat inductor so that when a current flows from the first signal terminal to the second signal terminal, a first magnetic field is generated from the first spiral-wound flat inductor and a second magnetic field is generated from the second spiral-wound flat inductor. The first magnetic field is in an opposite direction from the second magnetic field. The substantially cylindrical conductor is disposed so as to intersect the first magnetic field and the second magnetic field. The antenna may also be used to receive electron spin radiation.

Abstract: A broad frequency range phase shift circuit is responsive to a radio-frequency signal generated by a radio-frequency source and generates a lagging phase signal and a leading phase signal, 90° out of phase with the lagging phase signal, corresponding to the radio-frequency signal. An operational amplifier has a signal input that receives the radio-frequency signal from the radio-frequency source and generates a low impedance amplified output signal. A series resonant circuit receives the amplified signal from the operational amplifier and shifts the phase of the amplified signal in an amount that approaches 90° as the amplified signal frequency approaches DC to 0° as the amplified signal frequency increases to the cut-off frequency. A transmission line receives the amplified signal from the operational amplifier and has an electrical length substantially equal to one-fourth of a wavelength corresponding to the cut-off frequency.

Abstract: An antenna for generating radiation includes a primary E-field generating circuit and a secondary E-field generating circuit. The primary E-field generating circuit generates a primary E-field in response to a source RF signal being applied to the antenna. The secondary E-field generating circuit generates a secondary E-Field, disposed apart from the primary E-field, in response to the source RF signal and develops an H-field that is in time phase with the primary E-field. This causes the antenna to develop a radiation resistance as an indication of radiation.

Abstract: An antenna system for transmitting and receiving, in association with a radio device that develops an H-field and an E-field corresponding to a radio frequency power signal having a voltage and a current, the voltage having a phase relationship to the current. The antenna system includes a Hertz-type radiating element. A phasing and matching circuit is electrically coupled between the Hertz-type radiating element and the radio device. The phasing and matching circuit adjusts the phase relationship between the voltage and the current of the radio frequency power signal so that the H-field and the E-field are in nominal time phase. This enhances the performance of all of the antenna parameters in addition to allowing reduction in size.

Abstract: In an antenna system for transmitting and receiving, in association with a radio device, electromagnetic radiation has an E-field component and an H-field component. The electromagnetic radiation corresponds to a radio frequency power signal having a current and a voltage at a radio frequency. The antenna system includes a first radiating element and a second radiating element, each comprising a conductive material. The second radiating element is spaced apart from, and in alignment with, the first radiating element. A phasing and matching network is in electrical communication with the first radiating element, the second radiating element and the radio device. The phasing and matching network aligns the relative phase between the current and the voltage of the radio frequency power signal so that the H-field component of the corresponding electromagnetic signal is nominally in time phase with the E-field component.
