Thermal Black‐Infused Polyurethane Rigid Foams: Novel Formulations Toward Higher‐Performance and More Sustainable Insulation

Journal of Applied Polymer Science, EarlyView.
Thermal black improves polyurethane foam structure and stability. It helps the foam rise smoothly while promoting the formation of smaller, more uniform cells. The foam keeps its strength and insulation performance while reducing shrinkage. Its clean production and easy processing make it a sustainable, cost‐effective option for high‐performance ...

Low acoustic impedance arc-shaped chiral metamaterials for low-frequency and broadband underwater sound insulation

Materials & Design
This work proposes an arc-shaped chiral metamaterial (ACM) for low-frequency underwater sound insulation. The equivalent parameters of the designed arc-shaped chiral lattice (ACL) in the metamaterial are derived and evaluated using homogenization method.
