Surface structure and composition of high-surface-area molybdenum nitrides
(Elsevier, 1994-05-01)
The determination of surface structure is critical in elucidating structure-function relationships for catalytic materials. However, such materials often consist of active regions of very limited spatial extent, rendering ...
Methane to methanol in supercritical water
(Elsevier, 1994-06)
We examined the feasibility of producing methanol from the partial oxidation of methane in near-critical and supercritical water. Oxygen was always the limiting reactant. The parameter space investigated experimentally ...
Molecular analysis of the myosin gene family in Arabidopsis thaliana
(Kluwer Academic Publishers; Springer Science+Business Media, 1994-11)
Myosin is believed to act as the molecular motor for many actin-based motility processes in eukaryotes. It is becoming apparent that a single species may possess multiple myosin isoforms, and at least seven distinct classes ...
Ion-beam-assisted deposition of molybdenum nitride films
(Elsevier, 1994-08)
A series of molybdenum nitride films was synthesized by electron beam evaporative deposition of molybdenum, with simultaneous bombardment by nitrogen ions from a Kaufman ion source. The nitrogen ions were accelerated to ...
Traces of the arrival history in the jammed state of random sequential adsorption
(IOP Publishing Ltd, 1994-09-21)
In the final jammed state of the random sequential adsorption of dimers on a one-dimensional lattice, the average gap neighbouring a particle that originally adsorbed at time t is e-te-ee(-tt). Thus, the average final gap ...
The structure and function of supported molybdenum nitride hydrodenitrogenation catalysts
(Elsevier, 1994-03)
A series of [gamma]-Al2O3 supported Mo nitrides were prepared by the temperature programmed reaction of supported molybdates with NH3. Several loadings, heating rates, and space velocities were employed in an attempt to ...
Analysis of Cylindrical Wrap-Around and Doubly Conformal Patch Antennas Via the Finite Element-Artificial Absorber Method
(University of Michigan. Radiation Laboratory, 1994-09)
Optimal feedback control of batch reactors with a state inequality constraint and free terminal time
(Elsevier, 1994)
In this paper we derive optimal state feedback laws for end-point optimization of a dynamic system where the final time is free and the system has a scalar inequality constraint. The existence of a singular region as well ...
Detention and mixing in free water wetlands
(Elsevier, 1994-12)
Mixing was studied in free water surface wetland receiving pumped river water, by measurement of the non-interacting tracer lithium. The flow pattern was found to be intermediate between plug flow and well-mixed. The nominal ...
Temperature-programmed desorption of H2 from molybdenum nitride thin films
(Elsevier, 1994-07)
The thermal desorption of hydrogen from [beta]-Mo16N7, [gamma]-Mo2N and [delta]-MoN thin films was investigated. Hydrogen adsorption at [approximate]270 K produced two hydrogen desorption peaks, one at [approximate]370 K ...
