Based on the crystal size, yield and pH data, it is possible to postulate a model for silicalite crystallization in a high gravity environment. The primary effect of applying high gravity during the crystallization is to segregate the collodial silica... 

Acid drainage is an extreme case of gravity effects in VRLA cells. In very tall cells or in cells built with low surface-area or glass/organic hybrid separators combined with low compression levels electrolyte can actually pool in the bottom of the cell, even at moderate or high saturation levels. This creates a condition where the bottom of the cell charges as if it were a flooded lead-acid cell (which it is) and the upper portions of the cell try to function as a normal.

The capillary rise method provides very accurate values of interfacial tension if used carefully. The capillary tubes must not deviate significantly from a circular shape, must be of known and uniform radius, and must be carefully aligned in the vertical position. They must be cleaned or otherwise prepared to ensure that the contact angle is zero. Finally, Equation 1.64 must be corrected in experiments of high precision to accoimt for meniscus deviation from the hemispherical shape due to gravity effects. Equation 1.56 describes the meniscus shape in this case, since the situation is basically the same as that for a sessile bubble. Hence the...

Oiling involves the covering of aeolian material with a suitable oil product (e.g. high-gravity oil) that stabilizes the treated surface and may destroy dune forms. It is, in many deserts, a quick, cheap and effective method...
