  • Patent number: 10597340
    Abstract: Provided herein are methods and compositions for the electrochemical selective radiofluorination of aromatic molecules. The resulting fluorine-18 labeled compounds are ideal radionuclides for use in Positron Emission Tomography (PET); they are also difficult to radiolabel efficiently and with high specific activity using existing approaches. For example, radiopharmaceuticals such as [F18]L-DOPA, which is indispensable in PET brain disease imaging, may be made electrochemically with high radiochemical yield and high specific activity using 18F-. The invention process described herein opens new possibilities and provides wider access to PET tracers such as 18F-L-Dopa, since 18F- is much more widely available than the 18F2, currently used for synthesis of electron rich substrates.

    Abstract: A novel ferroelectric ink comprising multiphase Barium Strontium Titanate (BST) in a polymer composite is described. The ink can be employed using direct-ink writing techniques to print high dielectric constant, low loss, and electrostatically-tunable dielectrics on substrates. The substrates can be flexible such as plastics or rigid, such as substrates comprising semiconductor materials or ceramics and the like. The dielectric ink is made by suspending pre-sintered nano/submicron-sized particles of BST in a thermoplastic polymer with a solvent. After printing with the ink, a low temperature curing process is performed at temperatures below 200° C., a temperature too low to sinter BST. Fully printed devices, such as a varactor and a phase shifter using direct ink writing methodologies are described.

The nano-resin can comprise dicyclopentadiene having an uncured viscosity near that of water. The cross-linking process involves ring-opening metathesis polymerization and catalysis of the nano-resin in combination with a functionalizing material such as norbornene, to enhance bonding between the carbon and nano-resin.
