  • Publication number: 20190217273
    Abstract: In one aspect, the present invention provides a chromatographic stationary phase material for various different modes of chromatography represented by Formula 1: [X](W)a(Q)b(T)c (Formula 1). X can be a high purity chromatographic core composition having a surface comprising a silica core material, metal oxide core material, an inorganic-organic hybrid material or a group of block copolymers thereof. W can be absent and/or can include hydrogen and/or can include a hydroxyl on the surface of X. Q can be a functional group that minimizes retention variation over time (drift) under chromatographic conditions utilizing low water concentrations. T can include one or more hydrophilic, polar, ionizable, and/or charged functional groups that chromatographically interact with the analyte. Additionally, b and c can be positive numbers, with the ratio 0.05?(b/c)?100, and a?0.

  • Publication number: 20190141171
    Abstract: An enclosure and a method for forming an enclosure are disclosed. The enclosure may be formed from metal, such as aluminum, and further include a non-metal portion allowing for transmission and receipt of electromagnetic waves. The non-metal portion may be interlocked to the enclosure and in particular, to a region within the enclosure including a first material having a relatively high strength and stiffness compared to the non-metal portion. Interlocking means may include forming dovetail cuts into the enclosure to receive the non-metal portion, a hole or cavity drilled into the enclosure which includes internal threads, and a rod inserted into the first material to provide a tension to the non-metal portion. Methods of assembling internal components using anodization are also disclosed.

  • Patent number: 9812753
    Abstract: Radiofrequency and other electronic devices can be formed from textured hexaferrite materials, such as Z-phase barium cobalt ferrite Ba3Co2Fe24O41 (Co2Z) having enhanced resonant frequency. The textured hexaferrite material can be formed by sintering fine grain hexaferrite powder at a lower temperature than conventional firing temperatures to inhibit reduction of iron. The textured hexaferrite material can be used in radiofrequency devices such as circulators or telecommunications systems.

  • Patent number: 8835339
    Abstract: A framework for developing high quality factor (Q) material for electronic applications in the radio frequency range is provided. In one implementation, ceramic materials having a tungsten bronze crystal structure is modified by substituting one or more elements at one or more lattice sites on the crystal structure. The substitute elements are selected based on the ionic radius and other factors. In other implementations, the modified ceramic material is prepared in combination with compositions such as rutile or a perovskite to form a orthorhombic hybrid of perovskite and tetragonal tungsten bronze.

  • Patent number: 8696925
    Abstract: Embodiments disclosed herein include methods of modifying synthetic garnets used in RF applications to reduce or eliminate Yttrium or other rare earth metals in the garnets without adversely affecting the magnetic properties of the material. Some embodiments include substituting Bismuth for some of the Yttrium on the dodecahedral sites and introducing one or more high valency ions to the octahedral and tetrahedral sites. Calcium may also be added to the dodecahedral sites for valency compensation induced by the high valency ions, which could effectively displace all or most of the Yttrium (Y) in microwave device garnets. The modified synthetic garnets with substituted Yttrium (Y) can be used in various microwave magnetic devices such as circulators, isolators and resonators.

  • Patent number: 8609062
    Abstract: Processing techniques for forming a textured hexagonal ferrite materials such as Z-phase barium cobalt ferrite Ba3Co2Fe24O41 (Co2Z) to enhance the resonant frequency and other magnetic properties of the material for high frequency applications are provided. The processing techniques include magnetic texturing by using fine grain particles and sintering the material at a lower temperature than conventional firing temperatures to inhibit reduction of iron. The processing techniques also may include aligning M-phase (BaFe12O19 uniaxial magnetization) with non-magnetic additives in a static magnetic field and reacting with BaO source and CoO to form Z-phase (Ba3Me2Fe24O42). In some implementations, processing techniques includes aligning Co2Z phase (planar magnetization) with magnetic texturing occurring in a rotating magnetic field.
