Water Sorption Characteristics of Aluminum‐ and Calcium‐saturated Soil Clays

Soil Science Society of America Journal, 1986
Abstract Water sorption by Al‐ and Ca‐saturated bentonites and soil clays with montmorillonitic, mixed, illitic, and kaolinitic mineralogy were quantitatively evaluated at water vapor pressure levels ( P/P 0 ) of 0.50, 0.90, and 0.98 by thermogravimetry ...

ChemInform Abstract: DEPOSITION AND DISSOLUTION OF LITHIUM‐ALUMINUM ALLOY AND ALUMINUM FROM CHLORIDE‐SATURATED LITHIUM CHLORIDE‐ALUMINUM CHLORIDE AND SODIUM CHLORIDE‐ALUMINUM CHLORIDE MELTS

Chemischer Informationsdienst, 1981
AbstractAus einer an LiCl gesättigten A1C13‐Schmelze wird auf einem A1‐Substrat eine LiAl‐Legierung abgeschieden, und zwar vorwiegend durch einen Abscheidungsprozeß und nicht über einen Implantationsmechanismus.

Low Temperature Dehydration Kinetics of Aluminum‐ and Calcium‐saturated Soil Clays

Soil Science Society of America Journal, 1987
Abstract The kinetic parameters of the isothermal dehydration of standard bentonitic and soil clays with montmorillonitic, mixed, illitic, and kaolinitic mineralogy were studied under Al and Ca saturation. The isothermal temperatures employed under a constant water vapor pressure of

Saturation of normal-mode coupling in aluminum-oxide-aperture semiconductor nanocavities

Journal of Applied Physics, 2001
The photon density required for the saturation of normal-mode coupling in oxide-apertured nanocavities is measured to be 90 photons/μm2 by pump-probe experiments. The photon number is only 300 for a semiconductor nanocavity with a 2 μm diameter aluminum-oxide aperture, drastically reduced from 200 000 for a 50 μm waist on a planar microcavity.

Soil aluminum saturation threshold for subtropical crops in no-tillage system

Soil Research
Context Neutralising native soil Al3+ is crucial in subtropical agriculture before implementing no-tillage (NT). Aims The aim of this study was to monitor variations in soil Al saturation and crop yields over 34 years in a field trial ...

Thermodynamic calculation of the parameters of a reactor for oxidizing aluminum in wet saturated steam

Thermal Engineering, 2010
A model is considered that represents a chemical reactor for oxidizing aluminum in wet saturated steam to obtain a high-temperature and high-head flow of steam-hydrogen mixture, as well as aluminum oxides and (or) hydroxides. The thermal gas-dynamic parameters of the reactor are analyzed using a combined calculated and theoretical approach, which made ...

[Influence of the degree of saturation of iron stores on the gastrointestinal absorption of aluminum].

Revista espanola de fisiologia, 1989
The possible influence of iron metabolism in the regulation of aluminum gastrointestinal absorption in male Wistar rats has been studied. Three groups were considered: Fe overloaded Group 1; Fe normal Group 2; Fe depleted Group 3. All groups were exposed during 45 days to 40 mg of Al(OH)3 investigating the concentration of Al in serum and urine ...

Cation‐Exchange Equilibrium Constants of Aluminum‐Saturated Montmorillonite and Vermiculite Clays

Soil Science Society of America Journal, 1968
Abstract Equilibrium constants of aluminum‐saturated montmorillonite and vermiculite clay minerals were studied in chloride‐salt solutions at concentrations similar to those occurring in soil. Studies were limited to cations occurring most abundantly in soil solutions, viz., H +
