As an effort to support UNY's vision of becoming a world class university, recently a lecturer in the Chemistry Education Study Program, Dr. Antuni Wiyarsi, M.

Dr. Antuni Wiyarsi held research discussions and wrote publications in order to complete the post-doctoral program under the guidance of Prof. Dr. Muammer Çalık which was postponed due to the Covid-19 pandemic and visiting class.
