A dipole moment occurs whenever there is an overall unequal distribution of the electrons in a molecule, represented by large arrows pointing from the positive to the negative area of the molecule. Electronegativity and Polarity The direction of the dipole is determined by electronegativity, the tende...
However, the addition of rejuvenators will reduce the molecular polarity and improve damage resistances of asphalt (Ziari et al., 2019). Besides, rejuvenators containing hydroxyl or carboxyl have higher hydrophilia since –OH groups in rejuvenator molecules are similar to that in water molecules (...

Such a convention represents a critical improvement in the treatment of electronic polarization, allowing for better reproduction of molecular polarizability, directionality of hydrogen bonding, and response to environments of differing polarity. In the AMOEBA convention, molecules are divided into ...
Bond polarity and molecular shape determine molecular polarity, which is measured as a dipole moment. Polarity: Due to the difference in the electronegativity of atoms, a molecule does not possess the electrons shared or transferred during a bond form...
[97,98,99]. The barrier height is related to the energy level alignment of inorganic layers and organic spacer layers. Increasing the intrinsic polarity and dipole moment of spacer cations can enhanceϵrand relieve the dielectric mismatch effect between organic spacers and inorganic layers, ...
Polarity A polar molecule has its electrostatic potential distributed unevenly throughout the molecule. The resulting difference in electric potential is called a dipole moment . A water molecule consists of two hydrogen atoms bonded to an oxygen atom. The oxygen atom exerts a strong attractive force...

The optimization energies and dipole moments indicate that C165 has the highest dipole moment (13.679147 Debye), suggesting a higher polarity which could enhance its interaction with the 3FXI protein through dipole-dipole interactions. Fig. 13 Visual representation of HOMO, LUMO orbitals and optimized...
Results infer that addition of osmolytes to ethanol-treated catalase persuaded changes in solvent polarity and protein microenvironment leading to overall counteraction of ethanol-induced structural changes in catalase responsible for its aggregation. Fluorescence microscopy also confirmed the counteraction of ...
