Dielectric-calorimetric experiments

Figure 1.24. Absolute masses (m ) measured by combined dielectric-calorimetric experiments and Gibbs surface excess masses (mj,g) measured manometiically and also gravimetrically of carbon dioxide CO2 (4.5) adsorbed on Wessalite (Degussa DAY) atT= 298 K, [1.54].

I.R., dielectric and calorimetric methods (15-20). Keratin exhibits a single line spectrum by N.M.R. with line-width depending on orientation. This is in contrast to collagen which shows a three line spectrum. Lynch and Haly (15) have studied the influence of orientation on the spin-spin relaxation time of absorbed water in keratin from rhinoceros horn. A priviledged rotation of the water is observed around an axis approximately parallel to the fiber direction. From I.R. results Bendit proposes a weak association of water with carbonyl groups in the crystalline phase. I.R. experiment on deute-...
