The experiment observes network structures that go through a freezing-thawing cycle. Freezing-thawing cycles produce network structures identified as poly (vinyl alcohol) hydrogels. The formation of absolute crystallinity depends on the restrictions on cross-linked chain motion formed during gelation. These restrictions include the size of mesh in the network. Scientists performing the experiment believe that freezing-thawing cycles increase crystal size. The experiment determined that the melting of crystals during the cycle does not affect the network mesh size. The experiment also concluded that cross-linked networks can become an aqueous solution by increasing temperature in a freezing-thawing cycle. <span style="display: block; font-family: 'Times New Roman','serif'; font-size: 12pt; line-height: 200%; text-align: center;">Article Citation: <span style="font-family: 'Times New Roman','serif'; font-size: 12pt; line-height: 200%;">Valentín JL, López D, Hernández R, Mijangos C, Saalwächter K. 2008.

 * **<span style="font-family: 'Times New Roman','serif'; font-size: 12pt;">COMPARING ABSORBENCY OF DIFFERENT DIAPERS. Chapin. **<span style="font-family: 'Times New Roman','serif'; font-size: 12pt;">The purpose of this experiment intends to compare the absorbency capacity of four different brands of diapers. Each diaper brand receives three trials to create an accurate average. One 7×7 cm diaper square is submerged in a 500 mL beaker at one time. The beaker consists of a sodium chloride solution to represent uric acid. The square is removed and measurements are subtracted to determine the volume of solution absorbed. Each diaper square is measured dry to produce an accurate average mass to be used in for comparison. The background of the experiment focuses heavily on the superabsorbent polymer found in diapers called sodium polyacrylate. The physical experiment relies on the principle of molar mass to determine the appropriate amount of sodium chloride to create the 500 mL sodium chloride solution. The results of the experiment do not fully support the hypothesis. The diaper that weighed the most, Huggies Brand, did not absorb the greatest amount of solution. The experiment does not prove that a greater diaper square mass will absorb a greater volume of solution. Key words: sodium acrylate, sodium chloride, cross-linked chains, network. ||
