1. Enhanced anatase-to-rutile phase transformation without exaggerated particle growth in nanostructured titania–tin oxide composites

    Scripta Materialia 57(8):771 (2007)

    Through the use of titania–tin oxide nanocomposites, an enhanced anatase-to-rutile phase transformation is achieved, while avoiding appreciable particle growth. Upon the addition of SnO 2, the phase transformation temperature fell, reaching a minimum value at 18 vol.% of tin oxi...

  3. A one-step conversion of benzene to phenol with a palladium membrane.

    Science 295(5552):105 (2002) PMID 11778042

    Existing phenol production processes tend to be energy-consuming and produce unwanted by-products. We report an efficient process using a shell-and-tube reactor, in which a gaseous mixture of benzene and oxygen is fed into a porous alumina tube coated with a palladium thin layer and hydrogen is ...

  5. Microstructure and phase transformation behavior of doped nanostructured titania

    Materials Research Bulletin 34(8):1275 (1999)

    Microstructure and phase transformation behavior of doped nanostructured titania has been studied with a view to understanding the microstructural development for possible applications in the areas of catalysis and electronic ceramics. Sol-gel derived anatase titania gel was used as the pre...
  6. Critical nuclei size effect in the densification of nanostructured niobia ceramics

    Materials Research Bulletin 34(2):225 (1999)

    An effective technique for obtaining near-theoretical density niobium oxide by utilizing the critical nuclei size effect is reported. Dense nanostructured niobium oxide with more than 99% of the theoretical maximum and an average grain size of less than 90 nm was produced by sintering durin...
