Carbon foam structure can be created and treated with several shapes and geometries. Carbon dots (CDs), as a new type of carbon-based nanomaterial, have attracted broad research interest for years, because of their diverse physicochemical properties and favorable attributes like good biocompatibility, unique optical properties, low cost, ecofriendliness, abundant functional groups (e.g., amino, hydroxyl, carboxyl), high stability, and electron mobility. Generally, materials will degrade over time due to fatigue, environmental conditions, or damage incurred during operation. For instance, a foam-core sandwich has an extremely high strength to weight ratio in bending, but not necessarily in compression or crush. EPE foam has very low thermal conductivity and thus offers the best insulation against heat. SAP 2009 uses thermal mass in calculating the heating and cooling load of the building. Non Toxic And Food Safe: EPE foam is non toxic, and thus can be used for food packaging. Zong-Xian Zhang, in Rock Fracture and Blasting, 2016.
