Berkeley, California, USA - Recent Scientists at the University of California, Berkeley have developed a new material that can quickly suck up carbon dioxide from the ambient air, a major breakthrough in the fight against climate change. It has been created by the hands of Berkeley PhD chemistry student and Henan Province-born Zhou Zihui. He recalled the day when he put his creation - a yellow powder- to the test. He pumped air from outside the lab into a tube that mixed with his powder. "We can see the CO2 concentration dropped down from 460 directly to zero in like 5 minutes," he said. That professor is world-renowned chemist Omar Yaghi, who points out something perhaps even more important - the powder can be used over and over. Zhou's work utilizes Yaghi's invention - the covalent organic framework, a class of porous materials - which Zhou describes like a system of Lego. Today, captured CO2 is typically stored in the ground, though researchers and industries are experimenting with ways to convert it into fuel. Since publishing their findings, Zhou says he's already developed a next generation powder that is four to six times faster at absorbing CO2. The scientists say one of the next important and challenging steps is scaling up the production of their material, so that it can someday be deployed at plants around the world to rid the air of harmful emissions.

And, we were actually very excited. I told to our professor and, he said, okay, you have a very, very huge breakthrough."; [SHOT OVERLAYING SOUNDBITE] 6.

SOUNDBITE (English) Omar Yaghi, chemistry professor, UC Berkeley (starting with shot 8/ending with shot 10): "In his experiment, he cycled 100 times. That showed absolutely no degradation of the performance, which tells us that this material is going to be able to cycle many, many, hundreds of thousands of times."; 10.

SOUNDBITE (English) Zhou Zihui, PhD chemistry student, UC Berkeley (starting with shot 10/ending with shot 12): "So, the organic building blocks will combine with each other to form kind of pore space inside. Just like when we build a house by using Lego. The pore space in the molecule or the material can trap a lot of gas inside."; 12. Porous material; 13. Various of vials of yellow powder at lab; 14.

And I believe that, if you look back at the history of humans, there is nothing we can not solve."; 15. Various of Zhou at lab, bottles filled with gas; 16. SOUNDBITE (English) Omar Yaghi, chemistry professor, UC Berkeley (ending with shots 17-18): "A student like Zihui - their experience spans the entire spectrum of doing the basic science, understanding the properties of materials, but then solving a real problem in society. Our product is Zihui, not the material. Our product is educating the future generation to understand their potential."; 17. Zhou at lab; 18. Lab facilities; 19.
