Osaka University


Osaka University was founded in 1931 as one of the seven imperial universities of Japan and it remains today one of Japan’s leading comprehensive universities. The University houses more than 23,000 students and more than 6,600 faculty and staff members. Osaka University was named Japan’s most innovative university and is included among the most innovative institutions in the world according to the Nature Index 2017 Innovation publication. The University’s ability to innovate stems from its broad disciplinary spectrum and strong industry-university collaboration, as well as its engagement with, and contributions to, society. This strength is coupled with a drive for innovation that extends throughout the scientific process, from fundamental research to the creation of applied technology. The University continues to explore new research fields, develop greater innovation from the fundamental research stages, and make even greater efforts to pioneer interdisciplinary research projects.

With the motto “Live Locally, Grow Globally,” Osaka University has adopted a vision of openness for 2021. To this end, we strive to make our education, research and community more open and ensure that our three campuses are places where outstanding students and researchers from around the world can gather, learn, discover, and collaborate. Since integrating with Osaka University of Foreign Studies in 2007, Osaka University has enhanced its capacity in the studies of language and culture, and we are enhancing degree programs conducted in English and Japanese language support for international students and faculty. In recent years, the University has also actively expanded its global outreach by setting up overseas centers in San Francisco, Groningen, Bangkok and Shanghai.

Osaka University leverages its role as a Designated National University Corporation selected by the Japanese Ministry of Education, Culture, Sports, Science and Technology to contribute to innovation for human welfare, the sustainable development of society, and social transformation.

Seeing the bigger picture of jamming

Spheres randomly thrown together can jam over a wider range of conditions than previously thought, a new description of jamming reveals.

A wide range of materials exhibit the phenomenon of jamming in which their constituent particles become clogged together so that they are no longer free to flow. Randomly arranged spheres have been observed to jam when they reach a density of about 64%.

Now, by performing computer simulations of jamming of randomly assorted spheres, a researcher at Osaka University and a collaborator have shown that jamming can occur at lower densities than this, depending on factors such as the amount of shear and strain.

They have developed a more unified framework for jamming that covers jamming produced by both compression and shear mechanisms. The common factor is that the onset of jamming coincides with the formation of structures that are barely stable.
