  • Weak hydrogen bonds key to strong, tough infrastructure

    The right mix of hydrogen bonds in polymer and cement composites is critical to making strong, tough and ductile infrastructure material, according to Rice University scientists who want to mimic the mechanics of mother-of-pearl and similar natural composites with synthetic materials. Seashells made more

  • Boron nitride foam soaks up carbon dioxide

    Rice University materials scientists have created a light foam from two-dimensional sheets of hexagonal-boron nitride (h-BN) that absorbs carbon dioxide. They discovered freeze-drying h-BN turned it into a macro-scale foam that disintegrates in liquids. But adding a bit of polyvinyl alcohol (PVA) in more

  • Flexible supercapacitor raises bar for volumetric energy density

    Scientists have taken a large step toward making a fiber-like energy storage device that can be woven into clothing and power wearable medical monitors, communications equipment or other small electronics. The device is a supercapacitor—a cousin to the battery. This one packs an interconnected netwo more
