Second critical point of water in supercooled confined water in L,L-diphenylalanine micro/nanotubes
P. M. G. L. Ferreira, S. Kogikoski, W. A. Alves +1
The temperature dependence (10-290 K) of the low-frequency (20-150 cm-1) Raman-active phonon modes of supercooled confined water in L,L-diphenylalanine micro/nanotubes was analysed…

Extended versus localized vibrations: the case of L-cysteine and L-cystine amino acids
M. S. Ishikawa, T. A. Lima, F. F. Ferreira +1
A detailed quantitative analysis of the specific heat in the K temperature range for L-cysteine and L-cystine amino acids was presented. We observed not extended but a sh…

Quantum fluctuations, the Boson peak, and the glassy state of biomolecules
T. A. Lima, M. S. Ishikawa, H. S. Martinho
It has been recognized in the literature that some physical properties of hydrated biomolecules, e.g., the occurrence of Boson peak, resembles of those of glassy state. In the pres…
