  • Patent number: 8822697
    Abstract: The present invention relates to a paramagnetic polynuclear metal complex having enhanced self-relaxation rate and thermodynamic stability, and more particularly, to a synthetic method of a novel DTPA-bis-amide-histidine ligand and DTPA-bis-amide-aspartic acid ligand, a novel gadolinium complex ([Gd(L)H2O]) using the ligand, and a paramagnetic polynuclear metal complex using the gadolinium complex. The paramagnetic polynuclear metal complex is able to fix three or more metals (one gadolinium and two metal ions), thereby providing more excellent self-relaxation rate than the commercially available contrast agents. Thus, it can be widely applied to an MRI contrast agent because of meeting the high self-relaxation rate required as a contrast agent of magnetic resonance imaging (MRI).

  • Publication number: 20130082893
    Abstract: Provided herein are devices, systems and techniques for establishing a coincident-phased dual polarization array aperture enabling a wide scan capability, while also presenting a bandwidth of at least about 40%. Radiating elements of such an array include a first ground plane extending between lower and upper edges and a first radiating element positioned above the upper edge of the first ground plane. The array elements also include a second ground plane extending between respective lower and upper edges and disposed substantially orthogonal to the first ground plane. A second radiating element is positioned above the upper edge of the second ground plane, such that the first and second radiating elements have different polarizations. Parallel ground planes of adjacent antenna elements of an array of like elements enhance array performance by providing isolation between such radiating elements and backplane ground by way of a phenomenon generally known as waveguide-below-cutoff.
