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 ...
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 ...
Emulsion stability: Determination from turbidity
(Elsevier, 1981-01)
A novel technique for studying the stability of emulsions has been developed. Owing to the fact that emulsion turbidity is a function of particle concentration and size, the stability of emulsions can be determined by ...
Dynamics of growth of silica particles from ammonia-catalyzed hydrolysis of tetra-ethyl-orthosilicate
(Elsevier, 1988-07)
The NH3-catalyzed formation of colloidal silica particles from tetra-ethyl-orthosilicate (TEOS) in methanol and ethanol is studied by means of light scattering and Raman spectroscopy. We find that the growth is characterized ...
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 ...
Selected-area small-angle electron diffraction
(Kluwer Academic Publishers; Chapman and Hall ; Springer Science+Business Media, 1967-09)
Selected-area electron diffraction capable of resolving spacings up to 2000 Å from first-order discrete reflections has been achieved using a standard, double-condenser electron microscope. The technique allows photographing ...
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 ...
