Kinetic modeling of the reduction of nitric oxide in combustion products by isocyanic acid

James A. Miller、Craig T. Bowman1991-04-01International Journal of Chemical Kinetics

Abstract The RAPRENO x process for NO reduction in combustion products involves reaction of nitric oxide with isocyanic acid. We have developed a mechanism for the gas‐phase reaction of isocyanic acid with nitric oxide in the presence of various amounts of O 2 , H 2 O, and CO. Kinetics calculations using the mechanism…

Integrated ferroelectrics

Carlos A. Paz de Araújo、George W. Taylor1991-04-01Ferroelectrics

This paper attempts to formalize the field of Integrated Ferroelectrics. The history of devices that include ferroelectrics and semiconductor hybrids is reviewed. The modern ferroelectric device is a combination of ferroelectric thin-films onto a semiconductor single crystal substrate. The evolution of the field in th…

Three dimensionality of ‘‘metallic’’ states in conducting polymers: Polyaniline

Z. H. Wang、C. Li、E. M. Scherr 等 5 位作者1991-04-01Physical Review Letters

Anisotropic-conductiity (\ensuremath{\sigma}), thermopower, and dielectric-constant studies show that oriented polyaniline salt is representative of a class of quasi-one-dimensional disordered conductors where coupled parallel chains form ``metallic'' bundles in which electron wave functions are extended three dimensi…

Growth of Ge Microcrystals in SiO2 Thin Film Matrices: A Raman and Electron Microscopic Study

Minoru Fujii、Shinji Hayashi、Keiichi Yamamoto1991-04-01Japanese Journal of Applied Physics

The growth of Ge microcrystals in SiO 2 -Ge mixture films prepared by an rf co-sputtering method was studied by Raman spectroscopy and electron microscopy. It was found that in the as-deposited films, Ge clusters about 2 nm in diameter are embedded in SiO 2 matrices and they are grown to Ge microcrystals by thermal an…

Phonons at martensitic phase transitions of bcc-Ti, bcc-Zr and bcc-Hf

W. Petry1991-04-01Phase Transitions

Inelastic neutron scattering on in situ grown bcc single crystals of the group 4 metals Ti, Zr and Hf show a band of low energy and strongly damped phonons. Geometrical considerations show how these damped lattice vibrations achieve the displacements necessary for the two martensitic phase transitions from bcc to ω (u…

Design trades for Rotman lenses

R.C. Hansen1991-04-01IEEE Transactions on Antennas and Propagation

The foundation of a satisfactory Rotman lens design is geometric. The effects of seven design parameters (focal angle, focal ratio, beam angle ratio, maximum beam angle, beam port curve ellipticity, array element spacing, and focal length/ lambda ) on the shape, and on the geometric phase and amplitude errors of a Rot…

Dipolar-glass model for lead magnesium niobate

D. Viehland、J. F. Li、S. J. Jang 等 5 位作者1991-04-01Physical review. B, Condensed matter

The static polarization of lead magnesium niobate has been studied using a standard Sawyer-Tower circuit. The square-to-slim-loop hysteresis transition was phenomenologically modeled by modifying N\'eel's equation for the magnetization of a superparamagnet to a similar relationship for a superparaelectric. A temperatu…

Long-range Finnis-Sinclair potentials for f.c.c. metallic alloys

Hashem Rafii‐Tabar、A. P. Sulton1991-04-01OpenAlex

Many-body, long-range potentials of a Finnis-Sinclair type are formulated for the atomistic description of binary f.c.c. metallic alloys. These potentials are generalizations of the scheme constructed by Sutton and Chen (1990), for the atomistic modelling of f.c.c. elemental metals. The parameters for the alloy potent…

A detailed set of measurements is presented on determining the emission and absorption cross sections of Er/sup 3+/ doped fibers for the /sup 4/I/sub 13/2/ to /sup 4/I/sub 15/2/ transition. Two techniques are employed: the Fuchtbauer-Ladenberg analysis, based on spectroscopic data, and a more direct technique involvin…
