    An epoxy–anhydride formulation used for the coating electrical devices was modified with a commercially available hyperbranched poly(ester amide), Hybrane S2200, to improve the thermal degradability of the resulting thermoset ...
  • Multifractal observations of eddies, oil spills and natural slicks in the ocean surface
