Advanced Functional Materials, EarlyView.The study presents biodegradable and recyclable mixed‐matrix membranes (MMMs), hydrogels, and cryogels using luminescent nanoscale metal‐organic frameworks (nMOFs) and biopolymers. These bio‐nMOF‐MMMs combine europium‐based nMOFs as probes for the status of the materials with the biopolymers agar and gelatine and present alternatives to conventional ...

Wakefields in photonic crystal cavities
Physical Review Special Topics. Accelerators and Beams, 2009 Simulations of charged particle beams in accelerator cavities show that a two-dimensional photonic crystal can be used to create a three-dimensional hybrid cavity with a single operating mode and no significant higher order modes, greatly reducing long ...

Double Helical Plasmonic Antennas
Advanced Functional Materials, EarlyView.Plasmonic double helical antennas funnel circularly polarized light to the nanoscale, offering strong chiroptical interaction and directional light emission. Extending a single helix design tool, this study combines numerical modeling with experimental validation, revealing large, broadband dissymmetry factors in the visible range.

Ferroelectricity in Single‐Crystalline BaTiO3 Nanodisks on Silicon
Advanced Functional Materials, EarlyView.Ferroelectricity is studied in 20 nm thick single crystalline BaTiO3 nanodisks when scaling their diameter from ≈ 400 down to 100 nm. For 100 nm diameter, the vertical polarization component adopts three distinct patterns, and the lateral one shows a rotational invariance in‐plane, suggesting a combination of center‐type and flux‐closure domains.
