  • Patent number: 12247189
    Abstract: The present disclosure generally relates to an alignment mount for electrode device used to measure transepithelial/transendothelial electrical resistance (TEER) for cell culture models of endothelial and epithelial monolayers. The TEER electrode alignment mount includes a base having a top wall, a bottom wall and a sidewall shaped to fit within a culture tray chamber. An extension arm projects from a top wall of the base. A pair of through apertures are formed in the base on opposing sides of the arm to receive first and second electrodes therethrough, respectively. An optional adjustable sliding sleeve for changing the height of the arm can be selectively coupled to the extension arm.

  • Patent number: 7998239
    Abstract: A method of forming stable nanoparticles comprising substantially uniform alloys of metals. A high dose of ionizing radiation is used to generate high concentrations of solvated electrons and optionally radical reducing species that rapidly reduce a mixture of metal ion source species to form alloy nanoparticles. The method can make uniform alloy nanoparticles from normally immiscible metals by overcoming the thermodynamic limitations that would preferentially produce core-shell nanoparticles.
