A study of the infrared absorption spectra of thin amorphous films of molybdenum trioxide
(1989)
The spectra of thin amorphous films of MoO3 deposited by vacuum evaporation have been studied within the spectral range 4000-400 cm-1 by the Fourier transform infrared technique. Some samples in the thickness range 100 to ...
Infrared spectra of some thin amorphous films of MoO3-In2O3 deposited by vacuum evaporation
(1989)
The infrared absorption spectra of vacuum-evaporated MoO3-In2O3 thin films are reported for a series of films of varying compositions within the spectral range 4000 to 400 cm-1 and interpreted in relation to the spectrum ...
Extended conformal symmetries and U(1) currents
(1989)
The authors investigate the structure of extended conformal algebras generated by local chiral fields of spin 1,2,. . .,n using the Gelfand-Dickey algebra of formal pseudodifferential operators for the gl(n) algebra. The ...
Quantum mechanics of non-linear systems
(1987)
A generalisation of Weyl's correspondence rule and the associated Moyal bracket for systems with non-linear phase spaces that admit symplectic transitive group actions is presented. This provides a simple account with ...
Virasoro algebra anomalies and deformations
(1987)
The authors relate the anomalies of string theories to the mathematical obstructions of Dirac's canonical quantisation. The cohomological features of the deformation approach to the quantisation procedure determine the ...
Modified aluminophosphate molecular sieves: preparation and characterisation
(1988)
Crystalline microporous aluminium phosphate has been prepared in a variety of ways. The influence of the preparative conditions affecting the solid state properties of the resultant solids were studied. Quencg cooling of ...
The efficient removal of organic templating molecules from aluminophosphate molecular sieves
(1986)
Treatment with methanolic HCl leads to the complete removal of templating molecules from the title solid
Surface Species on Rh/Al203 During CO/H2 Reaction Studied by Transient Techniques
(1989)
Methanation of a 9/1 mixture of H2/CO at 180°0 has been studied by transient techniques in a gradientless microreactor. The use of isotopic techniques and temperature programmed reduction (TPR) made possible the measurement ...
The CO H2 reaction on Rh Al2O3. I. Steady-state and transient kinetics
(1989)
Various hydrogen titrations yield the surface composition of Rh Al2O3 during the CO H2 reaction at temperatures in the range 180-260 °C. There is a very small amount of active carbon Ca, 0.02-0.06 monolayer, and 0.70-0.98 ...
The CO H2 reaction on Rh Al2O3. II. Kinetic study by transient isotopic methods
(1989)
Transient isotopic methods have been used to study the CO H2 reaction over 5% Rh Al2O3 in the temperature range 180-260 °C. The steady-state tracing method permits the determination of the surface coverage of CO and active ...
