Influence of n -paraffin composition on the aging of wax-oil gel deposits
(Wiley Subscription Services, Inc., A Wiley Company, 2003-12)
An excess Gibbs free energy model is applied to investigate the influence of n-paraffin composition on the aging behavior of wax-oil gel deposits known to form in subsea petroleum transport pipelines. The aging of wax-oil ...
Low-Temperature SCR of NO with NH 3 over USY-Supported Manganese Oxide-Based Catalysts
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 2003-04)
A series of catalysts of manganese oxide, manganese–cerium and iron–manganese oxide supported on USY (ultra-stable Y zeolite) were studied for the low-temperature selective catalytic reduction (SCR) of NO with ammonia in ...
Cell affinity separations using magnetically stabilized fluidized beds: Erythrocyte subpopulation fractionation utilizing a lectin-magnetite support
(Wiley Subscription Services, Inc., A Wiley Company, 2003-03-20)
A magnetically stabilized fluidized bed is used to separate erythrocyte subpopulations. Binding specificity was obtained by immobilizing the lectin Helix pomatia Agglutinin (HpA) or Griffonia simplicifolia I (GSI) onto ...
Water-density effects on phenol oxidation in supercritical water
(Wiley Subscription Services, Inc., A Wiley Company, 2003-03)
Supercritical water oxidation (SCWO) experiments were performed in a tubular flow reactor at 420–465°C and 141–241 bar. Phenol was the organic reactant. Both pure water and a helium (1/3 by mol)–water mixture served as ...
Hydrogen storage in carbon nanotubes: Residual metal content and pretreatment temperature
(Wiley Subscription Services, Inc., A Wiley Company, 2003-06)
Hydrogen storage in MWNT was enhanced via the catalytic activity of NiMgO. The magnitude of the hydrogen to metal ratio for the MWNT/NiMgO system, combined with temperature programmed adsorption and desorption studies, ...
Exact Results for the Universal Area Distribution of Clusters in Percolation, Ising, and Potts Models
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 2003-01)
At the critical point in two dimensions, the number of percolation clusters of enclosed area greater than A is proportional to A −1 , with a proportionality constant C that is universal. We show theoretically (based upon ...
Approach to the glass transition studied by higher order correlation functions
(IOP Publishing Ltd, 2003-08-13)
We present a theoretical framework based on a higher order density correlation function, analogous to that used to investigate spin glasses, to describe dynamical heterogeneities in simulated glass-forming liquids. These ...
Nerve collagens from diabetic and nondiabetic Sprague–Dawley and biobreeding rats: an atomic force microscopy study
(John Wiley & Sons, Ltd., 2003-07)
Background Alterations in rat's nerve collagens due to diabetes may be related to the permanence of damage due to diabetic neuropathy. We (1) provide a methodology for determining the diameters of collagen fibers accounting ...
Transpiration-based micropump for delivering continuous ultra-low flow rates
(IOP Publishing Ltd, 2003-03-01)
In this paper we describe the design, construction and operation of a micropump that delivers continuous, ultra-low flow velocities at ∼100 μm s−1. The pumping concept is based on the commonly observed phenomenon of ...
