Hydrogen bond density

It is interesting to notice that in the whole temperature range, hydrogen bond density. 

The smaller difference in Gic compared to K c (Tables 10 and 11) reflects only the effect of the higher modulus of the MT Ii-y copolyamides owing to their higher hydrogen bond density. 

One of the more efficient and versatile methods of increasing solubility and one that does not require modification of the solute is to use an organic cosolvent. The cosolvent reduces the hydrogen bond density of aqueous systems, so that it is less effective in squeezing out non-polar solutes from solution. Cosolvents... 

In another exercise, the students were supposed to answer the question regarding differences between strong and weak acids they were requested to mark one of the following alternatives molar mass of add molecules concentration of hydronium ions (pH value) level of dissociation (Ks value) strength of hydrogen bonding density of acid concentration of metal ions . They were also requested to explain their choice. 

Although the bulky aromatic side group generally hinders free segmental motion, henc increasing the Tg of the polymer, the effect of chain separation seems to be dominant in case of OPh, SPh, and the lower hydrogen bond density probably accounting for the decrease in Tg. These polyamides with lower... 

Distribution of hydrogen bonds, density as well as radial distribution of water molecules, across the water cylinder were calculated. They showed the presence of water structure deep in the cylinder (about 6 A below the GMO heads). The obtained results may help to understand the role of water strucftire in processes of insertion of external molecules inside GMO/water structure. 

The initiation step in RNA synthesis also includes formation of a replication fork. Helicase separates the DNA strands at the origin of replication. As mentioned before, each DNA can have several origins, often characterized by a large population of A-T pairings. The lower hydrogen bond density of this pairing makes it easier for helicase to pull apart the chains. Once the DNA strands are separated, they form a Y shape (or fork) with helicase at the junction.
