Monitoring Chemical Reactions by Using Ion-Channel-Forming Peptides
(WILEY-VCH Verlag, 2006-03-06)
No Abstract
Macrosonics in industry : 4. Chemical processing
(Elsevier, 1975-01-01)
Acoustic irradiation can result in increased inter-phase mass and heat transfer rates. The second-order acoustic effects of cavitation, interfacial instability, radiation pressure and acoustic streaming are responsible for ...
Role of interfacial interactions on the anomalous swelling of polymer thin films in supercritical carbon dioxide
(Wiley Subscription Services, Inc., A Wiley Company, 2007-06-01)
It has recently been shown that thin polymer films in the nanometer thickness range exhibit anomalous swelling maxima in supercritical CO 2 (Sc-Co 2 ) in the vicinity of the critical point of CO 2 . The adsorption isotherm ...
The effects of suspended residual solids on the rheology of coal-derived liquids
(Elsevier, 1982-05)
The rheology of the products of coal liquefaction was investigated using a Weissenberg Rheogoniometer, Model R-16, modified to allow total-normal-force measurements. Solvent extracted oils and asphaltene fractions were ...
Three-dimensional streamlined finite elements: Design of extrusion dies
(John Wiley & Sons, Ltd, 1992-01-15)
A method to determine three-dimensional die shapes from extrudate swell and vice versa is presented using a three-dimensional Galerkin finite element method based on a streamlined formulation with the fluid velocities and ...
Self-propagating high temperature synthesis and dynamic compaction of titanium diboride/titanium carbide composites
(Kluwer Academic Publishers; Springer Science+Business Media, 2000-05)
Self-propagating High-temperature Synthesis (SHS) of titanium and boron carbide (B 4 C) combined with explosively driven Dynamic Compaction (DC) was employed for the fabrication of composite TiB 2 /TiC compacts. A 2 3 ...
Dissolution kinetics: Catalysis by salts
(Elsevier, 1981-07)
The dissolution of silicate minerals by hydrofluoric acid has been found to be catalyzed by salts such as NH4Cl, NaCl, and LiCl as well as by strong acids. This catalysis is a strong function of pH and is attributed to the ...
LETTER TO THE EDITOR: Exact critical exponent for the shortest-path scaling function in percolation
(IOP Publishing Ltd, 1999-10-29)
It is shown that the critical exponent g1 related to pair-connectiveness and shortest-path (or chemical distance) scaling, recently studied by Porto et al, Dokholyan et al and Grassberger, can be found exactly in two ...
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 ...
Excluded volume effects on the birefringence and stress of dilute polymer solutions in extensional flow
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 2000-10)
An algorithm is derived for calculating flow-induced birefringence using a bead-spring model with and without excluded volume effects. The simulation results for the bead-spring model compare well with experimental results ...
