Abstracts are not currently available in GtR for all funded research. This is normally because the abstract was not required at the time of proposal submission, but may be because it included sensitive information such as personal details.

Description | I've discovered universal structural characteristics that underlie granular systems close to the jamming transition and, consequently, that these disordered structures are NOT random even if they appear so when probed with other tools. I have developed further the statistical mechanics of granular systems. |
Exploitation Route | By using the methods and models I have developed. By collaborating with me on continuation of this research direction and building on the obtained results. |

Title | Quadron method |
Description | The quadron method is a way to describe tensorially the local structure of disordered granular, porous or cellular media quantitatively. The method had been invented before the award was given and developed further during the award. |
Type Of Material | Data analysis technique |

Provided To Others? | Yes |
Impact | This method allowed the group in Japan to characterise granular systems quantitatively and, as a result, to discover structural signatures, which could not be observed otherwise. |
