Cooperative hydrogen bonding and structural instability in water
نویسنده
چکیده
2014 We propose a model for liquid water in which the bonding states of each molecule are represented by a 5-level equivalent system. The structural effects are taken into account in a theoretical approach of the « meanfield » type, the mean-field (internal pressure) being supposed to decrease when the number of 4-bonded molecules increases. The model predicts the dependence of several thermodynamical parameters on T and P, and the existence of a structural stability limit which implies a divergence of 03B1P, 03B2T and Cp in the supercooled state. The existence of a structural critical point is discussed. J. Physique 44 (1983) 1201-1208 OCTOBRE 1983, 1 Classification Physics Abstracts 61.20 64.30

The mechanical properties of pristine graphene oxide paper and paper-like films of polyvinyl alcohol (PVA)-graphene oxide nanocomposite are investigated in a joint experimental-theoretical and computational study. In combination, these studies reveal a delicate relationship between the stiffness of these papers and the water content in their lamellar structures. ReaxFF-based molecular dynamics ...
متن کاملEvidences for Cooperative Resonance-Assisted Hydrogen Bonds in Protein Secondary Structure Analogs
Cooperative behaviors of the hydrogen bonding networks in proteins have been discovered for a long time. The structural origin of this cooperativity, however, is still under debate. Here we report a new investigation combining excess infrared spectroscopy and density functional theory calculation on peptide analogs, represented by N-methylformamide (NMF) and N-methylacetamide (NMA). Interesting...
متن کاملUV resonance Raman determination of molecular mechanism of poly(N-isopropylacrylamide) volume phase transition.
Poly(N-isopropylacrylamide) (PNIPAM) is the premier example of a macromolecule that undergoes a hydrophobic collapse when heated above its lower critical solution temperature (LCST). Here we utilize dynamic light scattering, H-NMR, and steady-state and time-resolved UVRR measurements to determine the molecular mechanism of PNIPAM's hydrophobic collapse. Our steady-state results indicate that in...
