Abstract Surfaces of metal oxides play a vital role in many technologically important applications. The surfaces of titanium dioxide, in particular, show quite promising properties that can be utilized in solid-state gas sensing and photocatalysis applications.Most of the ReRAM devices described to date have utilized thin film based metal oxide dielectrics as a resistive switching matrix. The goal of this dissertation project has been to investigate the resistive switching behavior of nanoparticulate metal oxides and to develop methods to utilize these materials in ReRAM device fabrication.Metal Oxide Nanostructures and Their Applications A thesis Submitted to the Department of Materials Science, School of Natural Sciences, University of Patras, in partial fulfilment of the requirements for the degree of Doctor of Philosophy BY Ghulam Nabi Dar University of Patras Department of Materials Science University of Patras Greece.


The selective oxidation and ammoxidation of light olefins comprises a 5 million ton per year industry, and is responsible for making possible products from nitrile rubber to Plexiglas to acrylic paint. The industrial catalyst of choice for such reactions is based on bismuth molybdate, and was first patented in the 1950s.The synthesis of nanocrystals is the core of the nanoscience. The highly controlled nanomaterials are desirable for the studies of catalysis, in order to unambiguously correlate the catalytic properties with the structure and composition of catalysts. In this thesis, highly controlled nanocrystals are synthesized through solution phase synthesis. Shape controlled nanocrystals can be.

Many transition metal- oxide films exhibit an electrochromic (EC) effect as they change their optical transmittance upon charge insertion or extraction. These materials may be integrated into multilayer devices, and the optical modulation is then produced by application of a small electrical voltage.

The ability of the interphase droplet reactor to synthesize other metal oxides was demonstrated by the synthesis of copper (II) oxide. Copper oxide sheet mesocrystals were formed in the absence of acetic acid. The presence of acetic acid in the droplet phase inhibited oriented attachment and produced copper oxide nanowires.

Abstract. Carbon monoxide oxidation was performed over the three different oxidation states of copper -- metallic (Cu), copper (I) oxide (Cu 2 O), and copper (II) oxide (CuO) as a test case for developing a model metal oxide catalyst amenable to study by the methods of modern surface science and catalysis. Copper was deposited and oxidized on oxidized supports of aluminum, silicon, molybdenum.
