Tokyo, 8 Oct - The Inter University Accelerator Centre (IUAC), India, and the Quantum Beam Center, NIMS, signed a MOU on collaborative research for "the Fabrication and modification of nano-materials by ion beams"

The accelerator generates high energy beam up to 200 MeV of heavy ions such as gold, silver, etc. This kind of the swift heavy ions seldom collide with the atoms in solids, and rather induce high-density electronic excitation in nanometric cylindrical regions along the ion trajectories. In the collaborative research, we focus on irradiation effects of the swift heavy ions on morphology and physical properties of nano-structures, such as metal and oxide nanoparticles embedded in insulators. We hope that this collaboration will open a door to the new paradigm which could be called "High-energy nanotechnology".
