  • Patent number: 9493436
    Abstract: A variety of benzofurans and indole derivatives some with an alkynyl linker are disclosed herein. These compounds are not highly charged at physiological pH and have good bioavailability characteristics. These compounds exhibit selective or at least preferential affinity for the active sites of various sub-sets of protein tyrosine phosphatases. Some of these compounds are excellent inhibitors of Mycobacterium protein tyrosine phosphatase B (mPTPB) a protein tyrosine phosphatase expressed in Mycobacterium tuberculosis and characterized as a virulence factor in the causal agent of tuberculosis. Accordingly, many of these compounds and pharmaceutically acceptable salts thereof are useful for the treatment of diseases such as tuberculosis.

  • Patent number: 9228460
    Abstract: An exhaust aftertreatment system includes an oxidation catalyst and a selective catalytic reduction (SCR) catalyst disposed in an exhaust stream of an internal combustion engine. A stay warm thermal management strategy is employed after warm-up of the aftertreatment system is complete to maintain the aftertreatment system above a temperature providing a desired performance threshold of one or more components of the aftertreatment system, such as the oxidation catalyst or the SCR catalyst.

  • Publication number: 20150328586
    Abstract: A method and system for mitigating a urea deposit within an SCR system that includes determining a mass of an accumulated urea deposit present within the SCR catalyst and SCR piping, comparing the mass of the accumulated urea deposit with a deposit upper threshold limit, and initiating an SCR regeneration event when the mass of the accumulated urea deposit is greater than the deposit upper threshold limit. The method further includes determining an amount of NH3 passing through the SCR catalyst downstream of the urea deposit, comparing the amount of NH3 passing through the SCR catalyst with an NH3 regeneration threshold limit, and terminating the SCR regeneration event when the level of NH3 passing through the SCR catalyst is less than the SCR NH3 regeneration threshold.

  • Patent number: 8716050
    Abstract: Described herein is a microchannel that is formed beneath and parallel to a surface of a silicon substrate. Silicon migration technology is utilized to form a microchannel that is buried beneath the surface of the silicon substrate. Etching opens at least one end of the microchannel. Oxidization is utilized through the open end of the microchannel to facilitate a controlled diameter of the microchannel.
