Abstract: Gadolinium-doped cerium oxide slurries used to form a patchwork type surface structure with nanoporous grain boundary prepared by mixing gadolinium-doped cerium oxide and a polymer binder to form a first mixture; wet-atomizing the first mixture under a pressure of at least 100 MPa to obtain a second mixture; coating the second mixture to a substrate to fog in a coated substrate; and sintering the coated substrate. The patchwork type structure is a polygonal or honeycomb structure having a size of from 0.1 ?m to 3 ?m.

Abstract: A nanocomposite membrane including an ?-Al2O3 membrane support, a ?-Al2O3 intermediate layer that is 300-1200 nm thick and coats a surface of the membrane support, and a nanocomposite layer including SiO2 and Y2O3 that is 25-150 nm thick and coats a surface of the intermediate layer, wherein the nanocomposite layer is porous with an average largest radius micropore of 0.2-0.6 nm. A method of manufacturing the nanocomposite membrane, whereby the membrane support is coated with the ?-Al2O3, a silica source is hydrolyzed with a mixture of water, an alcohol solvent, and a Y source with a sol-gel technique to yield a Si/Y sol-gel, the membrane support is dip coated with the Si/Y sol-gel, and the nanocomposite membrane is calcined. A method of separating a mixture of gas, whereby the mixture of gas is introduced into a permeance cell and fed through the nanocomposite membrane.

Abstract: A phthalocyanine radical anion stable in ambient atmosphere, which is formed by subjecting a salt containing dihalogeno(phthalocyaninato)antimony (V) cation to a one-electron reduction. According to the present invention, a phthalocyaninc radical stable in ambient atmosphere, which is expected to be developed as an n-type organic semiconductor, is provided.
