K. Jerie et al., POSITRON-ANNIHILATION IN AND COMPRESSIBILITY OF WATER-ORGANIC MIXTURES - THE SYSTEM WATER-ACETAMIDE, Acta Physica Polonica. A, 90(6), 1996, pp. 1169-1177
The experimental results of position annihilation experiments in aqueo
us solutions of acetamide were compared to those of ultrasonic velocit
y. The system under investigation behaves untypically when changing ac
etamide concentration. From the point of view of surface tension it in
teracts with water like normal alcohols, while the positron annihilati
on and ultrasonic results suggest hydrophilic hydration and lack of hy
drophobic interactions.
