Graphene. You know may know it as that wonder material that promises to change the way we build roads, craft smartphone screens, kill bacteria or even keep our feet cool. Composed of a one-atom thick sheet of carbon, graphene is thin and highly flexibility, strength and chemical stability. It also conducts electricity 100 times more effectively than copper and moves electrons 140 times faster than silicon (good for fast-charging).
The process looks something like a hi-tech sewing machine weaving an emblem onto a garment.
But soon the pattern begins to rise and swell, and a nose, constructed using a bio-ink containing real human cells, grows upwards from the glass, glowing brightly under an ultraviolet light.

Splitting water to produce hydrogen is one renewable energy vision of the future. But adding a simple carbon paste has created the first catalyst of its kind that can not only survive the harsh acidic conditions of water splitting,
