Here Is Another New Material: Metal Foam! by The Elephant's Child

Here’s another. North Carolina State University researchers have found that lightweight composite metal foams they have developed are effective at blocking X-rays, gamma rays, and neutron radiation, and are capable of absorbing the energy of high-impact collisions. These findings are promising for use in nuclear power plants, space exploration, and CT-scanner shielding.

“This work means there’s an opportunity to use composite metal foam to develop safer systems for transporting nuclear waste, more efficient designs for spacecraft and nuclear structures, and new shielding for use in CT scanners,” says Afsaneh Rabiei, a professor of mechanical and aerospace engineering at NC State, where they first developed the strong, lightweight metal foam made of steel, tungsten, and and vanadium for use in transportation and military applications.

But she wanted to determine whether the foam could be used for nuclear or space exploration applications — could it provide structural support and protect against high impacts while providing shielding against various forms of radiation?

Metal foams? Vanadium? And uses for blocking harmful rays, and for absorbing the energy of high-impact collisions. Amazing.
