"The volumetric properties of amino acids (DL-glycine, DL-alanine,
DL-serine, L-aspartic acid, L-lysine, and L-leucine) in aqueous
solution of nonionic surfactant hexadecyl poly[oxyethylene(25)] alcohol
(C(16)A(25)) are studied," scientists in Yerevan, Armenia report.

"The values of apparent molar volumes V-phi, partial molar volumes
V-2,m(0) and volumes of transfer Delta V-t2(2,m)0 are calculated,"
wrote N.G. Harutyunyan and colleagues, Yerevan State University.

The researchers concluded: "The changes of volumes of transfer are
discussed in terms of hydrophilic-hydrophobic interactions."

Harutyunyan and colleagues published their study in Thermochimica Acta
(Volumetric properties of amino acids in aqueous solution of nonionic
surfactant. Thermochimica Acta, 2010;498(1-2):124-127).
