Dear Colleagues,

On behalf of the Organising Committee, I am delighted to cordially invite you to join the 4th Young Researchers' International Conference on Chemistry and Chemical Engineering (YRICCCE IV), which will be held in Debrecen, Hungary during June 1-3, 2023.

This Conference is organised jointly by the Romanian and Hungarian Chemical Societies every two years. The Young Researchers' International Conference on Chemistry and Chemical Engineering conference series was launched in 2016 in Cluj-Napoca, Romania. We were very pleased to be the host of the second conference in Budapest, Hungary in 2018. Since the pandemic brought unexpected changes to our lives, we had to organize the 3rd conference online, but luckily we can return to the face-to-face meeting this year.

The YRICCCE series of conferences offers PhD students, postdocs and young researchers from universities, research institutes and industries the possibility to meet and discuss research topics, to exchange scientific ideas, to inspire new research, and to establish new contacts for closer co-operation.

I hope many young researchers will join us and contribute to the success of the conference.

Prof. Dr Livia Simon Sarkadi
Chair of the YRICCCE IV Conference
