How do you build the world’s lightest metal? Make it mainly from air ... hair — meaning that the material is 99.99 percent air. The structure is built using an innovative additive ...

Zinc-air batteries (ZABs) are emerging as a compelling alternative in the global race for better energy storage. They work by ...

the machine can print metal right into thin air. The oxide skin on the printed material is only a nanometer or so thick and therefore the structures remain conductive in the completed state.

Suppose that you had to build a tiny spring, antenna or other structure for use in a microelectronic ... It allows people to essentially draw minuscule metal items in mid-air.
