Molecular dynamics in DTGS (ND3) by quasielastic and inelastic neutron scattering

Vapour diffusion growth and characterisation of fully deuterated triglycine sulphate (ND2CD2COOD)3D2SO4

“…Growing fully deuterated TGS crystals would also allow phonon dispersion curves to be measured using neutron three-axis spectrometry or time-of-flight techniques. This could provide important new information about the interactions between the glycine molecules, since previous attempts to measure phonons in TGS have been restricted to techniques that are poorly sensitive to phonon dispersion such as Raman [17], Brillouin light scattering [7] and QENS [18]. None of the neutron techniques discussed above are practicable using hydrogenous TGS because the large incoherent neutron scattering cross section of hydrogen causes too high a background.…”

The enthalpies of solution of some dipeptides in aqueous urea mixtures at T=298.15K

“…Due to the variety of functional groups occurring in protein macromolecules and their complex structure, the results of their interactions in aqueous solution with other components are very difficult to interpret. Therefore many research centres carry out studies on the interactions of compounds whose molecular structure is characterised by the elements of protein structure such as methyl amides of natural amino acids [1][2][3][4], dipeptides [5][6][7], and tripeptides [8,9]. Our team has recently studied the interactions between the molecules of dipeptides, derivatives of glycin, and the molecules of urea.…”
