  • Patent number: 8529795
    Abstract: A method of preparing a wet-processible metal oxide solution and a method of fabricating a film using the same are provided. A metal oxide that has been widely used as a photocatalyst is improved and a metal oxide solution having new functionality is formed. The metal oxide solution is transparent, wet-processible, and facilitates electron transfer. The metal oxide solution can be applied in various ways to an electronic device and is well-suited for application to an electronic device using organic materials. Also, a titanium oxide solution functions to remove and block oxygen and moisture. Thus, when it is applied to an electronic device using organic materials that are vulnerable to oxygen and moisture, the lifetime of the device can be increased.

  • Publication number: 20120313038
    Abstract: A sludge or slurry physical stabilizing method combines coarse particles with a slurry of fine particles to generate a composite slurry having a substantially predetermined ratio of coarse particles to fine particles. The composite slurry can then be diluted, flocculated and dewatered. Superabsorbent polymer (SAP) is mixed in with the dewatered composite slurry in an amount effective to produce a somewhat friable, semi-solid conveyable composition of sufficient strength to enable transport, stacking and support of restored overburden at a mining site.
