A Chinese scientist aims to unlock the secrets of 2-D material. Xing Yi reports.

For more than a decade, Chinese physicist Zhang Yuanbo has been hunting for 2-D material in our 3-D world.

Zhang, 39, is one of the early scientists who tried to extract and analyze graphene, a carbon allotrope in the form of an atomic scale.

Graphene is hundreds of times stronger than steel.

Pioneering work on it won the Nobel Prize and opened the door to a whole new world of physics researching 2-D material.

"Scientists have since found more than 200 2-D materials," says Zhang, who works in Fudan University in Shanghai.

"The field is very active. Almost all the universities that I know pursue some kind of research related to it."

Graphene is a good conductor of electricity and the best conductor of heat among all known materials.

It is almost transparent, yet its structure is so dense even a gas atom cannot pass through it.
