The 7th International Conference on Nanostructuring by Ion Beams (ICNIB 2023) is being organized at the University of Petroleum and Energy Studies (UPES) Dehradun from 2-4 November, 2023, jointly with Inter University Accelerator Centre (IUAC) New Delhi. Energetic ions are increasingly playing a crucial role in nanostructuring and development of nanomaterials. Few keV energy ions in plasma have been used to grow nanoparticle thin films, whereas a few hundred keV ions from ion implanters are used to grow nanoparticles in a matrix. Higher MeV energy-heavy ions have also been used to grow and modify nanostructures. Ion beam irradiation induced synthesis and modification of nanostructures is the basic theme of this conference. 

The previous conferences in the series were organized at the University of Allahabad, Prayagraj (in 2011), Rajasthan University/ MNIT, Jaipur (in 2013), St. John’s College/Agra College, Agra (in 2015), Devi Ahilya University, Indore (in 2017), Indira Gandhi Centre for Atomic Research (IGCAR), Kalpakkam (in 2019), and Institute of Physics (IOP), Bhubaneswar (in 2021).
