Surface Energy - Calculating The Surface Energy of A Deformed Solid

Calculating The Surface Energy of A Deformed Solid

In the deformation of solids, surface energy can be treated as the "energy required to create one unit of surface area", and is a function of the difference between the total energies of the system before and after the deformation: .

Calculation of surface energy from first principles is an alternative approach to measurement. Surface energy is estimated from the following variables: width of the d-band, the number of valence d-electrons, and the coordination number of atoms at the surface and in the bulk of the solid.

    What our children have to fear is not the cars on the highways of tomorrow but our own pleasure in calculating the most elegant parameters of their deaths.
    —J.G. (James Graham)

    Because relationships are a primary source of self-esteem for girls and women, daughters need to know they will not lose our love if they speak up for what they want to tell us how they feel about things. . . . Teaching girls to make specific requests, rather than being indirect and agreeable, will help them avoid the pitfalls of having to be manipulative and calculating to get what they want.
    Jeanne Elium (20th century)

    If the man who paints only the tree, or flower, or other surface he sees before him were an artist, the king of artists would be the photographer. It is for the artist to do something beyond this: in portrait painting to put on canvas something more than the face the model wears for that one day; to paint the man, in short, as well as his features.
    James Mcneill Whistler (1834–1903)

    A government deriving its energy from the will of the society, and operating, by the reason of its measures, on the understanding and interest of the society ... is the government for which philosophy has been searching and humanity been fighting from the most remote ages ... which it is the glory of America to have invented, and her unrivalled happiness to possess.
    James Madison (1751–1836)

    I fairly confess that, acting as nature and simplicity dictated, no sooner did I see the once loved bosom of my Ferdinand free from those deformed demons which had crept in and filled up the vacant space, than beholding my natural home once more the seat of innocence and truth, my heart joyfully danced into its delightful abode.
    Sarah Fielding (1710–1768)

    The solid, solid universe
    Is pervious to Love.
    Ralph Waldo Emerson (1803–1882)
