Carbon foams are light weight thermos-structural materials used for high temperature thermal protection, fire resistant structures, EMI shielding and acoustic absorption. They are produced by the foaming, setting and carbonization of synthetic organic polymers and pitches. Biomasses are naturally renewable plant based materials available in large quantities at low cost. Sustainable development demands a shift from petroleum based raw materials to biomasses for the production of advanced materials.

Hemodynamics associated with the arteries of the circle of Willis (CoW) is analyzed to identify possible cerebral aneurysm initiation locations using computational methods. The wall shear stress distribution in the entire CoW region shows that anterior communicating artery (ACoA) junction has the highest value and risk of aneurysm initiation. The flow patterns created due to the geometrical features of the CoW seem to be the significant factor in the distribution of WSS. The wall weakening effects are more pronounced for the posterior communicating artery.
