Researchers have found a way to make ultralight sponge-like materials from nanoscale ceramic fibers. The highly porous, compressible and heat-resistant sponges could have numerous uses, from water purification devices to flexible insulating materials.

“The basic science question we tried to answer is how can we make a material that’s highly deformable but resistant to high temperature,” said Huajian Gao, a professor in Brown University’s School of Engineering and a corresponding author of the research. “This paper demonstrates that we can do that by tangling ceramic nanofibers into a sponge, and the method we use for doing it is inexpensive and scalable to make these in large quantities.”
