Context

Our Nanosciences team is geographically based at 2 different sites (Besançon and Montbéliard) and is specialized in the physical chemistry of surfaces and interfaces.


Goals and Research Areas

The team pursues activities in four different research areas:

› Nanosciences: the group’s activities bring together skills in synthetic chemistry, surface physics and near-field microscopies. With its interdisciplinary skills associated, the group studies the basic mechanisms of the growth of molecular self-assembly on semi-conductor and metallic surfaces.

› Nanotribology: in this activity team members study the fundamental phenomena controlling friction and wear in microsystems, calling upon an original approach using multi-asperity rather than single-asperity nanometric contacts.

› Micro-fuel cells: this activity falls within the area “Nanostructures and nanochemistry” and concerns the development of hybrid membranes composed of an inorganic skeleton made of porous silicon. An organic gel with chemical functions is grafted into the pores to produce the desired macroscopic function.

The team has notably developed infrared spectroscopy as a method of characterization. The method is well adapted to porous silicon which is transparent within this range of radiation, rendering it quantitative and thus enabling measurement of the molecules present within the silicon pores.

› Mathematical physics and quantum information: this concerns, above all, the arithmetic and geometry of the observables (for the multiple qubits and qudits of the general Pauli group) and applications to quantum computing. Deep links were first established between the qubits and Riemann’s theory of primary numbers, and then between the quantum paradoxes (of Bell and Kochen-Specker) of the topological and algebraic approach of Grothendieck, also called the “children’s drawings”.


Expertise

The Nanosciences team stands distinctly apart from its competitors who work on noble surfaces of metal or carbon, as its aim is for its hybrid organic-conductor systems to be compatible with technologies developed around silicon.
The group also pursues collaborative projects, when necessary to carry out its investigations, with recognized players in the fields of digital simulation or low-temperature spectroscopic techniques.
