  • Patent number: 11131925
    Abstract: Provided are a novel water-soluble diacetylene monomer, a composition for photolithography including the novel water-soluble diacetylene monomer and a conductive polymer, and a method of forming micropatterns using the composition. The water-soluble diacetylene monomer may not aggregate even when mixed with a water-soluble conductive polymer. Accordingly, a uniform composition for photolithography can be prepared by mixing a water-soluble conductive polymer with the diacetylene monomer, and micropatterns can be formed using the composition. More particularly, when the composition is formed into a thin film and then is irradiated with light, only light-irradiated portions of the diacetylene monomer are selectively crosslinked due to photopolymerization, thereby resulting in insoluble negative-type micropatterns.

  • Patent number: 8304537
    Abstract: Heterocyclic compounds incorporating a [1,3]oxazine ring may be used to make chromogenic materials. These molecules switch from a colorless state to a colored form upon addition of either acid or base. In both instances, the [1,3]oxazine ring opens in response to the pH change forming an indolium cation, after the addition of acid, or a phenolate anion, after the addition of base. Alternatively, the switch may occur in response to a change in electrical current or potential or a change in temperature. Chromophores absorb in the visible region of the electromagnetic spectrum. Hence, their formation translates into the appearance of color. These processes are fully reversible and the original colorless state can be regenerated by switching the pH back to neutral. Thus, these halochromic compounds can be used to develop displays, filters, indicators, lenses, sensors, switches, or windows able to switch their color in response to pH changes.

  • Patent number: 8252209
    Abstract: We have designed a molecular switch based on the photoinduced opening and thermal closing of a [1,3]oxazine ring. A substituted [1,3]oxazine compound described as having a general (i.e., unsubstituted) structure with fused indoline and benzooxazine fragments such that they share a common bond in the [1,3]oxazine compound: (i) the bond connecting positions 1 and 2 of the indoline fragment and (ii) the bond connecting positions 2 and 3 of the benzooxazine fragment. Irradiation by light of suitable wavelength and intensity of this photochromic compound induces cleavage of a [C—O] bond of the [1,3]oxazine ring to form a phenolate chromophore. The photogenerated (e.g., colored) isomer may revert thermally to the starting (e.g., colorless) oxazine. Alternatively, the switch may be between isomers of the compound that absorb at different wavelengths. Reversible coloration of silica or polymeric materials and switching optical signals may involve many cycles of interconversion between different colored states.

  • Patent number: 8129673
    Abstract: A method for logging a subsurface formation includes acquiring neutron capture data using a pulsed neutron tool at a plurality of locations along a borehole penetrating the subsurface formation, wherein the plurality of locations include a formation zone that contains water; comparing an apparent water salinity or an apparent water sigma value estimated from the neutron capture data acquired in the formation zone that contains water with a water salinity or water sigma value of a water sample from the subsurface formation to produce a calibration parameter for the neutron capture data; and correcting the neutron capture data, based on the calibration parameter, to produce corrected neutron capture data. The method may further include determining a water saturation from the corrected neutron capture data.

  • Patent number: 8048974
    Abstract: The invention relates to a acrylated-based optical coating composition containing an organic peroxide initiator which presents a low yellowness level. The initiator has a range of free radical energy that is below a predetermined level. The cure process is controlled by the use a catalyst and a low energy initiator to avoid deleterious reactions that can increase yellowness. The composition is well suited to be applied to a lens and cured in the mold to form a coating with reduced yellowness having high adhesion and abrasion-resistant properties. A dye can be introduced into the composition to form a tinted lens.
