Water Permeates and Plasticizes Amorphous Carbon Dots: Unraveling the Inner Accessibility of the Nanoparticles by Glass Transition Studies

open access: yesAdvanced Materials, EarlyView.
The water permeability of amorphous carbon dots (CDs) is demonstrated by investigating their plasticization. Novel polyamide‐based and amorphous nanoparticles are synthesized by controlling their inner packing density. Water plasticization is evidenced by the decrease of the CDs glass transition temperature with increasing the hydration degree.

Quantum nonlinear optics in strongly interacting atomic ensembles

open access: yes, 2020
The coupling of light to ensembles of strongly interacting Rydberg atoms via electromagnetically induced transparency (EIT) has emerged as a particularly promising approach towards quantum nonlinear optics, allowing freely propagating photons to acquire long-ranged effective interactions of unprecedented strength.

Solvent‐Free Thermal Defect Engineering in Molecular Frameworks With Volatile Linkers

open access: yesAdvanced Materials, EarlyView.
Thermal removal of neutral volatile linkers enables precise and solvent‐free generation of metal vacancies in MOFs. This strategy affords redox‐stable, coordinatively unsaturated FeII sites with tunable spin, ligand coordination, and catalytic behavior. The approach offers a general route to design defect‐functional materials through local coordination

Probing atom-surface interactions with an atomic quantum sensor

open access: yes
This thesis presents the first force measurements at close range between an atom and a surface, which was the ultimate objective of the Forca-G project. The force is measured by atom interferometry with atoms trapped in potential wells formed by a vertical optical lattice.

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

open access: yesAdvanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and
