My first scientific paper in 1961 reported an additivity rule for substituent-induced shifts of proton NMR signals in steroid derivatives.

Molecular chemistry, the chemistry of the covalent bond, is concerned with uncovering and mastering the rules that govern the structures, properties and transformations of molecular species.

Supramolecular chemistry is the chemistry of the intermolecular bond, covering the structures and functions of the entities formed by association of two or more chemical species.

In 1998, I set up and directed a research group at the Nanotechnology Institute newly created in the Research Center of Karlsruhe. This allowed to offer to former post-doctoral coworkers the opportunity to develop and to progressively set up independent research activities in nanoscience and nanotechnology.

People acting in their own self-interest is the fuel for all the discovery, innovation, and prosperity that powers the world.

Fiction, maybe art in general, is a tentative, uncertain enterprise; it's not science, it's an exploration, but you never find much in the way of answers.

Chemistry was my college interest. Cooking is about chemistry.

Science should always be in the business of attempting to disprove itself.
