Elements atomic percentage calculated by element analysis
from EDX spectra; nitrogen adsorption−desorption isotherms and images of contact angle measurements of BCA and
HBCAs; absorption kinetic curves of different oils and organic
sorbents; compressive stress−strain curves of oil-filled HBCAs-
3 and the relative analysis of the mechanical properties of oil-
filled HBCAs-3; and movies showing the removal of plant oil
with HBCAs-3 from water surface, removal of chloroform with
