| Outline of Final Research Achievements |
The solvent transportation behavior from mechanically constrained agarose gels was studied. The compression load and the volume of the agarose gels decreased with time during compressive restraint. The decrease in volume was induced by squeezing of the solvent from the gel by compressive restraint. Relaxation of the compression load and the decrease in volume of the gels could be analyzed using a stretched exponential function; moreover, interestingly, both time constants were coupled. The effect of glycerol and sucrose on the solvent transportation behavior of mechanically constrained agarose gels was also studied. Both time constants increased with an increase in glycerol and sucrose concentration. These results indicate that glycerol and sucrose changes the gel network structure, and this is confirmed by other experimental evidences which obtained by using electro-microscopy.
