Comparison of rigid and flexible simple point charge water models at supercritical conditions
(John Wiley & Sons, Inc., 1996-11-30)
This study investigates the differences between the predictions of various properties of rigid and flexible simple point charge water models at supercritical conditions. Molecular dynamics simulations were conducted for ...
Annealing effects of polymers and their underlying molecular mechanisms
(Elsevier, 1976-04)
This paper indicates that changes in chain mobility, heat capacity, WAXS crystallinity, SAXS long period, SAXS peak intensity, specific volume and morphology as a function of increasing temperature, occur in three fairly ...
Chemical permeabilization and in situ removal of daidzein from biologically viable soybean (Glycine max) seeds
(Kluwer Academic Publishers; Chapman and Hall ; Springer Science+Business Media, 1998-09)
After 24 h of chemical permeabilization with 20% (v/v) methanol at 25 °C, the amount of daidzein released from soybean seeds is 15 to 20% of the amount (0.0423 ± 0.0045 mg/g seed dry wt) obtained by physical grinding. With ...
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 ...
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. ...
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 ...
