  • Publication number: 20150021519
    Abstract: A method to recover caustic from a caustic waste stream comprises reducing the temperature of a caustic waste stream comprising dissolved Na2CO3 to a temperature less than or equal to the temperature at which the Na2CO3 precipitates from the caustic waste stream to form a caustic waste stream comprising precipitated Na2CO3 and separating the precipitated Na2CO3.

  • Patent number: 8694738
    Abstract: A system and method in one embodiment includes modules for detecting an access attempt to a critical address space (CAS) of a guest operating system (OS) that has implemented address space layout randomization in a hypervisor environment, identifying a process attempting the access, and taking an action if the process is not permitted to access the CAS. The action can be selected from: reporting the access to a management console of the hypervisor, providing a recommendation to the guest OS, and automatically taking an action within the guest OS. Other embodiments include identifying a machine address corresponding to the CAS by forcing a page fault in the guest OS, resolving a guest physical address from a guest virtual address corresponding to the CAS, and mapping the machine address to the guest physical address.

  • Publication number: 20130327977
    Abstract: The present invention provides compositions and methods for polishing a molybdenum metal-containing surface. A polishing composition (slurry) described herein comprises an abrasive concentration of an inorganic particulate abrasive material (e.g., alumina or silica) suspended in an acidic aqueous medium containing a water soluble surface active material and an oxidizing agent. The surface active material is selected based on the zeta potential of the particulate abrasive, such that when the abrasive has a positive zeta potential, the surface active material comprises a cationic material, and when the particulate abrasive has a negative zeta potential, the surface active material comprises an anionic material, a nonionic material, or a combination thereof.

  • Patent number: 8252687
    Abstract: The invention provides a chemical-mechanical polishing composition for polishing a substrate. The polishing composition comprises silica, a compound selected from the group consisting of an amine-substituted silane, a tetraalkylammonium salt, a tetraalkylphosphonium salt, and an imidazolium salt, a carboxylic acid having seven or more carbon atoms, an oxidizing agent that oxidizes a metal, and water. The invention further provides a method of chemically-mechanically polishing a substrate with the aforementioned polishing composition.
