From: Evolution of porous materials from ancient remedies to modern frameworks

Ancient civilizations throughout the world used porous materials for medicine (left), and in the 18th century (middle), scientific study of these materials began. Modern scientific research has benefited and built upon this historical field and developed next-generation materials for applications such as carbon capture and clean energy (right).
