Although a water molecule has an overall neutral charge (having the same number of electrons and protons), the electrons are asymmetrically distributed, making the molecule polar. The oxygen nucleus draws electrons away from the hydrogen nuclei, leaving the hydrogen nuclei with a small net positive ...
H2O@C60 is a remarkable molecule that consists of a polar molecule encapsulated into a highly symmetric and nonpolar cage. For H2O@C60, the polarity is no longer associated with its external shape. The encapsulated water molecule can rotate freely around the center inside the cage. In this ...
Guest inclusion was highly selective and a difference of even one methylene group in the organic guest molecule was discriminated by the host. Polar organic molecules with longer methylene chains and nonpolar molecules such as dinitrogen and methane were completely excluded. The guest-inclusion ...
[49], [50] have proposed a Padé dipolar term that is applied at the segment, rather than molecule level, and has been used by Tumakaka and Sadowski [57] within the perturbed chain SAFT (PC-SAFT) equation to describe mixtures of polar and nonpolar fluids. PC-SAFT has also been ...
Large channels with a polar lining are formed in the crystals of [Phe4,Val6]antamanide, whereas in natural antamanide large channels in the crystal are completely surrounded by the lipophilic side groups of the Pro, Phe, and Ala residues. Antamanide, C64H78N10· 8H2O· X, crystallizes...
