Abstract A model of geometrical interface with inherent elastic stress is developed. The general formulas for interface stress, tension and free energy density of condensed matter as well as their relations are derived. The constitutive relationship of the interface is also discussed. The results so obtained all agree with the current theories, and some new conclusions are drawn.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
