The result shows:The reaction time for using of the oxide was shorter and the ratio surface of the super-thin oxide was smaller.

The results showed that the biodegradability of the films was strongly correlated with starch content of the films and impacted by ratio surface area of the films.

The bigger the animal is, the lower its surface-to-volume ratio; for every ounce of body mass, there is proportionately less surface through which heat can escape.

The result, they claim in a paper that will appear this month in the Journal of Physical Chemistry, is a nanofibre material with an extremely high ratio of surface-area to volume.

But as an object gets smaller, the ratio between its surface area and its volume rises.

The family of these materials includes much-touted, carbon-based members such as graphene and nanotubes, and are notable in part for their surface area-to-weight ratio.
