Dipole Moment The dipole moment is a measure of the unevenness, or lack of symmetry, of the charge distribution in a molecule. The mathematical definition of the dipole moment involves adding up the size of each charge in the molecule multiplied by the average distance that charge is from an ...

SCA is a molecule with two functional groups, and one of them can react with the hydroxyl groups of cellulose of the plant fiber and another one can react with cementitious matrix [59]. What’s more, SCA can improve the ITZ between plant fibers and cementitious matrix by reducing the ...
The symmetry of a molecule is useful for determining certain material properties, such as their vibrational modes or their electronic states. For further details on the symmetry properties of fullerenes, we refer the reader to Dresselhaus et al. (1996). The particular structural configuration of ...

Hydrogen bonding is the attractive interaction that occurs between a hydrogen atom bound in a molecule to an electronegative atom such as oxygen or nitrogen and another electronegative atom from a different molecule (intermolecular) or even from the same molecule (intramolecular). ...
