Since the realization of the imperative need to reduce our dependence on fossil fuels, we have witnessed an unprecedented enthusiasm in the scientific community for the design of photovoltaic cells. Indeed, the possibility of using sunlight on a large …

This lecture is the counterpart of the previous one in that it concerns the photoanode of the same photoelectrochemical cell. However, there are currently very few bioinspired molecular systems (based on non-noble metals such as manganese) satisfactory …

" If it is in our very nature to produce the future, the system is arranged in such a way that our forecasts must remain uncertain. " François Jacob, Le Jeu des possibles, 1981, p. 130 [you are not, you become]. The game It was with a chapter on …

Abstract The first lesson was devoted to a discussion of the differences between classical and quantum bits, followed by a review of the elementary operations underlying classical calculus. The aim of this reminder was to introduce the fundamental concept …

The first two lectures (May 5, May 12) focused on quantum impurity models, such as the Kondo model. Originally introduced to describe magnetic impurities in metals, these models have enjoyed a recent revival of interest, in connection with the physics of …

At the dawn of the 20th century Major questions about the universe What was the picture of the universe that science was proposing at the beginning of the 20th century? Our Galaxy, with its Milky Way, was already fairly well known, and both its size and …

The development of a photoelectrochemical cell involves the creation of photoanodes (which oxidize water to generate electrons) and photocathodes (which recover electrons to convert water into hydrogen). These electrodes need to combine light collection, …

Some microorganisms have a metabolism that enables them to consume or produce molecular hydrogen by means of enzymes known as hydrogenases. Crystallographic characterization of [NiFe]-hydrogenases in 1995 and [FeFe]-hydrogenases four years later revealed …
