  • Patent number: 11104815
    Abstract: A single-walled carbon nanotube composition includes single-walled carbon nanotubes substantially enriched in semiconducting single-walled carbon nanotubes in association with a polymer having one or more oligoether side groups. The oligoether side groups render the composition dispersable in polar organic solvents, for example alkyl carbitols, permitting formulation of ink compositions containing single-walled carbon nanotubes substantially enriched in semiconducting single-walled carbon nanotubes. Such ink compositions may be readily printed using common printing methods, such as inkjet, flexography and gravure printing.

  • Patent number: 7402713
    Abstract: Tyrosine was converted to p-hydroxystyrene in a two-step reaction without purification of individual intermediates. Conditions were determined for bromination of tyrosine in which reactive intermediates were formed. The mixture of these intermediates was used directly in a second step reaction to produce p-hydroxystyrene. The p-hydroxystyrene was further acetylated to produce p-acetoxystyrene in the second step reaction vessel.

  • Patent number: 7201876
    Abstract: Ion-detecting sensors for detecting a target ion in a sample are provided. The sensor comprises a plasticizer-free copolymer comprised of polymerized units of methacrylate monomers having pendent alkyl groups of different length and a functionalized ionophore of said ion, wherein at least a portion of the functionalized ionophore is grafted into the copolymer through covalent linkages. Sensors may comprise ionophores such as hydrophilic crown ethers or functionalized derivative of 3-oxapentandiaminde-type ionophores. This invention further provides sensors for detecting target ions in a sample, comprising plasticizer-free molecularly imprinted polymers, wherein the polymers comprise polymerized units of methacrylate monomers having pendent alkyl groups of different length and a functionalized ionophore of said ion. In particular, a magnesium ion sensor comprising a functionalized derivative of a 3-oxapentandiaminde-type calcium ion-selective ionophore is provided.
