  • Patent number: 11236250
    Abstract: The present application provides switchable, homogeneous paint composition and methods of painting and/or forming films or coatings using the composition. The composition includes a liquid having an aqueous solution and dissolved acid gas (e.g., carbonated water), and a switchable polymer. The switchable polymer converts from a protonated, water-soluble form in the liquid to a water-insoluble unprotonated form following removal or substantial removal of the liquid and acid gas.

  • Patent number: 10377647
    Abstract: Methods and systems for use of switchable water, which is capable of reversibly switching between an initial ionic strength and an increased ionic strength, is described. The disclosed methods and systems can be used, for example, in distillation-free removal of water from solvents, solutes, or solutions, desalination, clay settling, viscosity switching, etc. Switching from lower to higher ionic strength is readily achieved using low energy methods such as bubbling with C02, CS2 or COS or treatment with Bronsted acids. Switching from higher to lower ionic strength is readily achieved using low energy methods such as bubbling with air, inert gas, heating, agitating, introducing a vacuum or partial vacuum, or any combination or thereof.

  • Publication number: 20160244548
    Abstract: The present application provides a composite material that comprises a solid and solid-supported non-polymeric switchable moiety, wherein the switchable moiety comprises a functional group that is switchable between a first form and a second form, said first form being neutral and hydrophobic, and said second form being ionized and hydrophilic. The composite material converts to, or is maintained in, said second form when the switchable moiety is exposed to CO2 at amounts sufficient to maintain the ionized form. The composite material converts to, or is maintained in, said first form when CO2 is removed or reduced to an amount insufficient to maintain the ionized form. CO2 is removed or reduced by exposing the composite material to heat and/or a flushing inert gas such as N2, Ar, or air. Envisioned uses of these composite materials includes removing water from non-aqueous solvents, removing water vapour from gaseous mixtures, and cleaning industrial reaction vessels and/or pipelines.

  • Patent number: 7907161
    Abstract: Adaptive correction techniques are disclosed that adaptively correct aberrations which may arise in systems such as laser printers, for example. For laser printers, calibration data processing results may be detected by a detector that is disposed to correspond physically to the recording medium so that characteristics such as position and intensity of a laser beam at the detector corresponds to that of a laser beam at the recording medium. In this way, aberrations in system performance may be adaptively corrected while the system is performing operational processes.
