The introduction of this asymmetrical H-bonding unit into the structure results in a complete disruption of liquid crystallinity while a "pseudo re-entrant" phenomenon is observed in the binary mixture phase diagram.doi:10.1080/15421400590955190
Do hydrogen atoms of different water molecules bond with each other? 13. Can two water molecules bond with each other as shown in the image? 14. Is the shown geometry of the water molecule correct? 15. If the geometry in the image was the geometry of water, would wate...

V and VI and VII) have disordered hydrogen bonding. The phases with ordered hydrogen bonding are found at lower temperatures and are indicated in light blue below. The structural transformation conditions of some of these...
c Along the glass transition isochrones, there is superposition of dynamics for the two van der Waals liquids, PPE and cumene, while in the hydrogen bonding liquid, DPG, there is a clear shift in the data with pressure. PPE and cumene were measured on IN5 and DPG on IN6. No scaling ...
Proline-induced kink in helix H1. H1 is one of the three helices containing theMCFmotif. Except for labeled residues, only mainchain atoms of H1 residues are represented. Intrahelicalhydrogen bondsalong H1 are depicted in gray. The carbonyl of T23 is within hydrogen bonding distance of W70, ...
the molecular orbital digram of methane shows that there are 4 molecular bonding orbitals.but one out the three bonding orbitals is of a lower energy and is explained to have a nodal plane. I don't understand why only one of the molecular bonding orbitals has a node, when carbon's valence...
Hydrogen Bonding Governs the Elastic Properties of Poly(vinyl alcohol) in Water: Single-Molecule Force Spectroscopic Studies of PVA by AFM The mechanical properties of single poly(vinyl alcohol) (PVA) and poly(vinyl acetate) (PVAc) molecules under different solvent conditions were investigated...
