Polyurethane foam can be divided into two categories, such as open-cell and closed-cell foam. The former is a plastic with incomplete cell walls and include holes through which air and liquid can ...

A new plant-based substitute for polyurethane foam eliminates the health risk of the material, commonly found in insulation, car seats and other types of cushioning, and it’s more environmentally ...

An environmentally-friendly preparation of plant material from pine could serve as a substitute for petroleum-based chemicals in polyurethane foams. The innovation could lead to more environmentally ...

Aurélie Hourlier‑Fargette, winner of the 2025 JPhys Materials Early Career Award, discusses the inspirations behind her interdisciplinary work on bubble assemblies and foam-based materials ...

Lightweight composite metal foams are effective at blocking harmful radiation, according to a new study carried out by researchers in the US. Indeed, the foams can efficiently block X-rays, gamma rays ...

Composite metal foams (CMFs) are intriguing materials, offering several big advantages over traditional solid metal. And while the welding of CMFs usually poses some challenges, it has now been been ...

Per- and polyfluoroalkyl substances (PFAS) have been used in aqueous film-forming foams (AFFFs) for fighting liquid fuel fires since the 1970s. Fluorine-free foams are foams that do not contain any ...

Tokyo, Japan – Researchers from Tokyo Metropolitan University have solved a long-standing mystery behind the drainage of liquid from foams. Standard physics models wildly overestimate the height of ...

Liquid foams have a remarkable property: they completely block the transmission of sound over a wide range of frequencies. Physicists have studied how sound is attenuated in liquid foams. Their ...
