MXene-coated devices can guide microwaves in space and lighten the payload

One of the most important components of satellites that enable telecommunication is the waveguide, which is a metal tube for guiding radio waves. It is also one of the heaviest payloads satellites carry into orbit. As with all space technology, reducing weight means reducing the amount of expensive and greenhouse gas-producing fuel it takes to launch a rocket or increasing the number of devices carried by the same rocket to space.
