The dielectric constant of isolated and purified lignin, obtained from black liquor, has been evaluated using a high frequency chemical oscillometer. The value of dielectric constant obtained above has been doubly verified ...

Eighty per cent of the urethanase activity of Micrococczu sp. isolated from the marine sponge Spirastrella sp. was cell associated. The urethanase had optimal activity at pH 5.0 and 45 degrees C. The activation and ...

The salt susceptible rice (Oryza sativa L.) cv. Jaya and salt resistant cv. Damodar seed germination and seedling growth rates were studied in laboratory and field conditions. The effect of salinity on seed germination, ...

Adsorption of selenite (Se-3(2-)) on different polymorphic forms of iron oxyhydroxides and amorphous ferrihydrite was studied as a function of time, temperature, pH, and concentration of adsorbate(s) and adsorbent(s). ...

Hematite particles of various shapes and sizes have been prepared hydrothermally at different pH values ranging from 3 to 10 from ferric chloride solution at 180 degrees C. Particle size decreases with an increase in the ...
