Densities of l-alanine/l-glutamine/glycylglycine + 0.512 mol·kg–1 aqueous K2SO4/KNO3 systems have been measured for several molal concentrations of amino acids/peptide at different temperatures from T = (298.15 to 323.15) K using a density and sound velocity meter (Anton Paar DSA, 5000 m). Using the density data the partial molar volumes (ϕv0) and transfer partial molar volumes (Δtrϕv0) have been calculated. The measured and calculated thermodynamic parameters have been discussed in terms of zwitterion–ion, zwitterion–water dipole, ion–water dipole, and ion–ion interactions operative in the systems.

Additional Information
The two enantiomers of 2-(2-hydroxybiphenyl-4-yl)propanoic acid ((S)- and (R)-BPOH) have been selected as probes for human serum albumin (HSA). Photophysical characterization in the absence of protein led to emission maxima, singlet energies, quantum yields, and fluorescence lifetime values ... more
The photodissociation of H2O in its B band is a prototype for nonadiabatic reaction dynamics. In addition to dissociation via the adiabatic pathway to the OH(Ã2Σ+) + H fragments, it also produces the OH(X̃2Π) + H fragments through two nonadiabatic pathways: the B̃ → X̃ transition via two co ... more
Due to the widespread occurrence in the environment and potential risk toward organisms of fluoroquinolones (FQs), it is of importance to develop high efficient methods for assessing their occurrence and environmental risk. A monoclonal antibody (Mab) with broad cross-reactivity to FQs was ... more
Rohm and Haas Powder Coatings is delighted to announce that its Reading, Pennsylvania, facility is the first site in the world to receive the RCMS® Site Certification awarded by the American Chemical Council (ACC). When Raj Gupta, Chairman and CEO of Rohm and Haas Company, became Chairman ... more
