Surface energy

  1. Dec 10, 2013 #1

    During discussion with colleagues on a paper we hit a problem which we could not solve. Could someone help us out. Is the If surface energy/stress of a microsphere with a diameter of 5μm larger or smaller compared to the one of a 30μm microsphere. According to the Hamaker constant I guess the surface energy of the larger sphere decreases compared to the smaller sphere.
    To clarify I am looking for the surface energy within the microsphere and not between microspheres.

    I hope you can help as I got a bit lost in my thoughts

    kind regards

    The surface energy of a solid is highly variable, because a solid can support shear stress. I expect the manufacturing process of the microspheres is more important than the size.

    Thanks Andy, I will take it into consideration in my discussion!
