Some days, the carbon nanotubes and carbon nano-wire as if to attract the attention of all. But, in fact, we should not overlook the other promising molecular structure of carbon unique ball shape. The ball back the name, based on Buckminster Fuller’s first name to name, and it contains 60 carbon atoms. Carbon atoms in the structure consisting of spherical molecules of carbon known as fullerene balls (fullerenes), a member of the fullerene carbon ball, the smallest is the ball back. Barker ball that can accommodate as many as 2000 atoms.

Today, Rice University (Rice University) latest research shows that carbon back the ball can be used to store hydrogen, but also the density of storage is sufficient when the central density and Jupiter match. For the alternative energy industry, hydrogen storage is one of the most difficult challenges. At the same time, hydrogen fuel cells and hydrogen fuel research in the field, for the human out of the traditional reliance on fossil fuels is critical, but also by a lot of good people. However, the objective difficulty of hydrogen storage, these new technologies restricted the civilian economy at large-scale development of the field. And we all know that hydrogen is incredibly light. Therefore, in the automotive field, in order to allow large-scale hydrogen energy and fuel competition in the fuel supplement on, on the need for greater density of liquid hydrogen to supplement the way, this is a difficult challenge.

This new research will be in March 2008 as the “The United States chemical industry” (American Chemical Society) Journal of periodical publications “Nano Letters” (Nano Letters) published the cover article. The hydrogen storage research before and after the cost of one billion U.S. dollars, sponsored by the United States Energy Board. Fellow director of the study, Rice University’s mechanical engineering and materials science professor Boris Yakobson results for the latest excited. He said, “By our calculations, this study shows that some are able to save the ball back a lot of hydrogen, and the storage density of metal almost catch up. The results showed that the ball back to the storage of their self-respect of the approximately 8% of hydrogen. At room temperature, the score is already quite good, compared to 6% compared aim high for a lot. ”

This is the ball back from 60 carbon atoms. This great ball to save some atoms in the internal sphere, including hydrogen.

Yakobson admit, the molecular hydrogen is stored in the container has a long history of ideas. Rather, the ball back to accommodate the idea of hydrogen has been known in the past has been. However, Yakobson, also Olga Pupysheva before and two post-doctoral researcher Amir Farajian the new study, only the first one used to calculate the damage in the back before the ball was able to be accommodated in the method of the number of hydrogen atoms.

This result is very interesting. 20 years ago, the first ball back at Rice University, was found today, the ball on the back of new research carried out at Rice University. Yakobson explained how the small balls are hydrogen storage, he pointed out that “the chemical bond between carbon atoms, the natural world are one of the most powerful chemical bonds, which form a chemical bond can understand the most current material and diamond hard. But our research showed that the ball in order to make these fullerene carbon in the carbon – carbon chemical bond deformation or damage, then takes a great deal of internal stress. ”

Researchers use an advanced computer models, can be estimated that this new method the details of storage. When the hydrogen atoms have been injected into the ball back, this model can be specifically measured the ball back in the chemical bonds between carbon atoms of the intensity. The model used to calculate the size of these various structures of carbon fullerene ball are ideal in particular, it shows that not only can back the ball can be stored in the number of hydrogen atoms, and when to simulate the internal storage capacity was the biggest breakthrough , Barker is how the breakdown of the ball.

Yakobson said the ball back is full of hydrogen can theoretically store the same powder. He said, “They are probably not very hard convergent synthesis of molecular crystals or form a small powder. These full of hydrogen molecules to form the ball back the crystal or powder-like substances, under certain conditions, should be used to release pure hydrogen for fuel cells or other forms of engine to use. ”

We can imagine the results if this be able to successfully get large-scale civilian use of the economic field, we will be how the lives of enormous change. Light motor vehicles can use a clean hydrogen fuel, the air will become fresh. Fuel cells to be more popular, many electronic products will be safe to use high-capacity portable fuel cell. Mobile is not charging the 23 Tianyi; when MP3 will not enjoy the power of the often; digital camera according to over 1,2 G after the memory card, batteries or full of; notebook battery life is no longer only a few hours; In addition, the electric car ride friends, do not need a dozen or so every day 1 steelyard weight of 20 kilograms of batteries … … . only need to get a bottle of the security light on the “ball back irrigation hydrogen fuel” , time off, simply twist open the lid, added fuel to get all … … This is a good blueprint for how.
