Web31 jul. 2024 · Professor Sjoerd Harder. Professor Harder’s work lies in organometallic chemistry, an area that combines organic molecules with metals. Organometallic compounds are so reactive that they burn away with contact in air – not just through oxygen, some react with nitrogen in air, despite this being a gas that is normally fully inert.
