Thermodynamics of the ternary systems: (water + glycine, l-alanine and l-serine + di-ammonium hydrogen citrate) from volumetric, compressibility, and (vapour + liquid) equilibria measurements

Volumetric, ultrasonic and UV absorption studies on interactions of antibiotic drug chloramphenicol with glycine and its dipeptide in aqueous solutions at T = (288.15–318.15) K

“…For understanding the solute-solvent and solute-solute interactions in solutions, thermodynamic and physicochemical measurements are very applicable [1][2][3][4][5]. We know that that the stabilization of native conformations of biological macromolecules (proteins) is related to various non-covalent interactions including hydrogen-bonding, electrostatic and hydrophobic interactions [6,7].…”

Volumetric and compressibility behaviour of poly(propylene glycol) – Amino acid aqueous solutions at different temperatures

“…Besides, our previous study [20] showed that the structure-breaking property of amino acids is so smaller than ordinary salts such as (NH 4 ) 2 HCit.…”

“…from which values of the infinite dilution apparent molar isobaric expansibility of solute, 0 φ E , were obtained as [20]:…”

“…The [31]) and most amino acids [14,20] Furthermore, close examination of figure 4 shows that the infinite dilution apparent molar expansibility per monomer of polymers in water follows the sequence PVP10000 ˃ PPG725 ˃ PPG400 ˃ PEG6000 ≈ PEGDME2000 ˃ PEGDME500 ˃ PEGDME250. Data for the calculation of 0 φ E of PPG400, PEG6000, PEGDMEs and PVP were taken from the references [21], [23], [33] and [34], respectively.…”

Equation for solvent activity correlation in ternary solutions with electrolyte and molecular components

“…Dependences of solvent activity (a 1 ) on molality of both components for the system di-Ammonium Citrate (2) -Glycine -Water(1) at 298.15 K. Dots: experimental data[26]; surface : correlation with Eq (21)…”
