An iron-anthracene dyad was recently used to populate a microsecond-lived nonluminescent (dark) triplet state, but with a surprisingly low triplet population yield.

This study demonstrates a novel integration of 2D semiconductors with ferromagnets using pulsed laser deposition, revealing hybridization-driven spin manipulation. Vertical spin valves with MoS2 and Ni(111) show exotic bimodal spin signals and strong deviations from Jullière’s model. These results highlight the « 2D spinterfaces » key role in unlocking 2D materials’ potential for advanced spintronic applications and novel spin functionalities.

High-energy excited states with slow rates for internal conversion to the lowest-energy excited state are prone to be intercepted before they dissipate energy to the medium.

For this demonstration, a 50 nm-thick film of the ferroelectric polymer polyvinylidene fluoride–trifluoroethylene (PVDF-TrFE) was used to engrave the 600th anniversary logo at the microscale. Jean Spièce, a researcher in the BSMA division, programmed a scanning probe microscopy tool to locally “draw” arbitrary shapes by precisely modifying the material’s polarization.

Oriane Froment (BSMA) won the best poster award at the annual meeting of the SoftComp EU Network of Excellence (May 19-22 in Venice, Italy). The topic of her poster was "Introducing vitrimers in electrolytes for lithium-metal batteries" by Oriane Froment, Carla Barakat, Charles-André Fustin and Jean-François Gohy
