Recent advances in COI’s oxide-oxide CMC materials will be presented including basic processing steps, updated material properties, and fabrication techniques. Material properties of COI’s alumino-silicate system reinforced with various oxide fabrics will be compared, along with progress in developing a 1200°C oxide matrix system for future turbine ...

Measuring Thermal Conductivity of Fluids Containing Oxide Nanoparticles
, 1999Oxide nanofluids were produced and their thermal conductivities were measured by a transient hot-wire method. The experimental results show that these nanofluids, containing a small amount of nanoparticles, have substantially higher thermal ...

Training and operation of an integrated neuromorphic network based on metal-oxide memristors
Nature, 2014Despite much progress in semiconductor integrated circuit technology, the extreme complexity of the human cerebral cortex, with its approximately 1014 synapses, makes the hardware implementation of neuromorphic networks with a comparable number of ...

Oxidation and oxidation protection
1993Over the past decade the development of structural carbon-carbon materials has received a great deal of attention. Potential uses have been cited in future generation military aircraft, missile systems and a number of proposed hypersonic aerospace vehicles.

Silicon dioxide has many desirable properties: an optical material of wide band gap known by many as the stable insulating oxide which helps silicon retain its supremacy in microelectronic devices. I shall discuss some of the recent studies increasing our understanding in three main areas: oxidation processes; interface issues; and processing and its ...

Modelling oxide–oxide and oxide–metal interfaces
J. Chem. Soc., Faraday Trans., 1990Recent years have seen a large increase in interest in interfaces of ionic and ceramic crystals and an appreciation of their importance in determining many of the properties of materials. Static-lattice calculations have made a major impact on the interpretation of the role of point defects in controlling observed behaviour in the bulk and are now ...

The decomposition of nitrous oxide on neodymium oxide, dysprosium oxide and erbium oxide
Journal of Catalysis, 1973Abstract The decomposition of nitrous oxide on neodymium oxide, dysprosium oxide and erbium oxide has been studied in two pressure ranges of approximately 1 to 10 Torr and 10 to 100 Torr, over a temperature range of 400 to 600 °C. In all cases, the kinetics are first-order in nitrous oxide with a pseudo-rate constant varying with initial pressure ...
