water still poses a number of scientific puzzles. Researchers led by Johannes Hunger at the Max Planck Institute for Polymer Research have investigated the bonds between a water molecule and its neighbors in the liquid phase. They have discovered that the distances to neighboring molecules are...
The bonds between neighboring water molecules are not purely randomly distributed: Each water molecule forms a strong and a weak bond. This could be a key to explain anomalies of water. MPI-PIcebergs float on water because the underlying liquid water has a higher density than the iceberg. ...

As shown in Figure 4, for CAM-B3LYP (top) and PBE0 (bottom), when the hydrogen bonds with the water molecules of the first solvation shell were considered in our calculations, the general agreement with the experiments remarkably improved. In particular, in the vRR spectra at 257 and 290 ...
The forces holding the micelle together are hydrophobic interactions between protein groups, cross-links between peptide chains by the nanoclusters and ionic bonds.The nanocluster model (Figure 2.29, Holt 1992, De Knuif and Holt 2003) is described as a tangled web of flexible casein molecules ...
