The International Conference on Nanoscience and Nanotechnology (ICONN 2025) is a joint venture of School of Chemical and Materials Engineering (SCME), National University of Sciences and Technology (NUST) and the Department of Chemistry and Chemical Engineering, Lahore University of Management Sciences (LUMS). The conference will be focused on various aspects of nanoscience and nanotechnology. This conference will bring together researchers from various fields to share ideas, problems and solutions relating to the development of nanomaterials, nanodevices and nano processes. This conference will provide an opportunity to bring together students, researchers and professionals across the country and abroad and provide a platform to create links that may enrich the professional networks among the participants. Most importantly, this event will lead to a closer cooperation and collaboration between the relevant faculty members working in both institutions (NUST and LUMS). First ICONN 2018 was hosted by NUST while second conference of the series was hosted by LUMS in 2019. It is therefore, envisaged to arrange ICONN each year on rotation basis.
