Liquefaction
Science› Biotechnology and Genetics
Food Biotechnology
Enzymatic digestion (often by alpha-amylase) of gelatinized starch to form lower molecular weight polysaccharides.
Renewable Energy
The process of converting biomass from a solid to a liquid. The conversion process is a chemical change that takes place at elevated temperatures and pressures.

Solar Energy
Refers to a sudden loss of strength and stiffness in loose, saturated soils. It causes a loss of soil stability and can result in large, permanent displacements of the ground.

Water
When a solid form is turned into a liquid form. During an earthquake, low density materials act like water and lose their supporting strength. A condition whereby soil undergoes continued deformation at a constant low residual stress or with low residual resistance, due to the buildup and maintenance of high pore water pressures, which reduces the effective confining pressure to a very low value. Pore pressure buildup leading to liquefaction may be due either to static or cyclic stress applications, and the possibility of its occurrence will depend on the void ratio or relative density of a cohesionless soil and the confining pressure.
