A generalised approach to torsionality maximisation in longitudinal-torsional ultrasonic devices [PDF]
, 2011 A longitudinal-torsional vibration mode has many applications in ultrasonic systems. Obtaining this behaviour could be achieved either by coupling the longitudinal and torsional modes or by degenerating the longitudinal mode, but the results may be ...

Chiral Metal Halide Perovskites for Spin‐Polarized Light‐Emitting Diodes
Advanced Materials, EarlyView.Chiral metal–halide perovskites offer a route to circularly polarized light without external polarizers. This Perspective compares two spin‐light emitting diode concepts: intrinsically chiral emissive layers and chiral spin‐filter interlayers that inject spin‐polarized carriers into efficient achiral emitters.

Advanced Materials Interfaces, EarlyView.A near‐infrared photosensitizer that facilitates efficient solid‐state photon upconversion by recycling triplets formed within a fullerene‐based donor–acceptor bulk‐heterojunction system is demonstrated. Spectroscopic investigations reveal that the energy of photogenerated charge transfer states of triplet character (3CT) is subsequently transferred to
