Fe---P---0 catalysts for methane utilization--catalyst development and identification
(Elsevier, 1990-05)
Fe---P---0 catalyst formulations show great promise for oxidative coupling of methane. They attain yields of C2 hydrocarbons comparable to the best in the literature at a temperature which is far below those reported. The ...
Modeling ssDNA electrophoretic migration with band broadening in an entangled or cross-linked network
(WILEY-VCH Verlag, 2007-08)
We use a coarse-grained model proposed by Graham and Larson based on the temporary network model by Schieber et al.. [1] to simulate the electrophoretic motion of ssDNA and corresponding band broadening due to dispersion. ...
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 ...
Gravity-induced flocculation
(Elsevier, 1984-09)
In polydisperse colloidal systems, flocculation can occur as a result of the differential creaming rates between small and large particles. As an improvement on earlier work, we have rigorously modelled this process of ...
Kinetic Separation of Oxygen and Argon Using Molecular Sieve Carbon
(Kluwer Academic Publishers; Springer Science+Business Media, 2000-01)
A pressure-swing adsorption (PSA) simulation study was performed for the separation of a mixture of 95% O 2 and 5% Ar using a molecular sieve carbon (MSC) as the adsorbent. Two PSA cycles have been outlined to maximize the ...
Dephasing of optically induced excitonic coherences in semiconductor heterostructures
(Springer-Verlag, 2000-11)
Resonant optical excitation of a direct bandgap semiconductor below the band edge induces excitonic coherences. Experiments based on transient four-wave mixing or cw spectral-hole burning provide an excellent approach to ...
Monte Carlo simulation of the adsorption of co on pt(111): thermodynamic considerations for the surface configuration of adsorbed species
(Elsevier, 1991-02-02)
We have developed a "two-site" lattice gas model which provides a theoretical framework for understanding adsorption equilibrium in systems for which the potential energy surface is inherently heterogeneous in terms of ...
Signal-Amplifying Conjugated Polymer–DNA Hybrid Chips We appreciate financial support from the National Science Foundation (BES 0428010) and the equipment grant from the University of Michigan College of Engineering. J.K. and K.L. also acknowledge the Ilju Foundation for the Ilju scholarship.

Hydrogen adsorption at dislocations and cracks in Fe
(Elsevier, 1978-12)
Solute adsorption to dislocations and cracks is considered in both the Boltzmann and Fermi-Dirac models. Explicit sums are developed for the integral amount of solute adsorbed in the defect fields. Examples of the use of ...
Synthesis and characterization of molybdenum nitride hydrodenitrogenation catalysts
(Elsevier, 1992-06-30)
Details concerning the relationships between the structural, chemical and catalytic properties of Mo nitrides have been elucidated. A series of Mo nitride catalysts were prepared by the temperature programmed reaction of ...
