We are pleased to invite you to participate in the 14th edition of the International Conference on Hydrogenase and Other Redox Metalloenzymes. This conference will encompass a comprehensive range of topics in fundamental and applied research, including microbial hydrogen metabolism, bioinorganic chemistry, computational chemistry, and the synthetic design of biomimetic catalysts. The scope also extends to related redox (bio)catalysts involved in chemical energy conversion, including but not limited to nitrogenases, formate dehydrogenases, and CO-dehydrogenases.
