Packed for Ossification: High‐Density Bioprinting of hPDC Spheroids in HAMA Toward Endochondral Ossification

Advanced Healthcare Materials, EarlyView.
Human periosteum‐derived cell spheroids bioprinted at high density within a hyaluronic acid matrix promote fusion and hypertrophic cartilage formation in vitro. Early encapsulation enhances spheroid interaction and matrix maturation, generating scalable cartilage templates intended for endochondral bone regeneration.

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced 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

Dynamical Birefringence: Electron-Hole Recollisions as Probes of Berry Curvature

Physical Review X, 2017
The direct measurement of Berry phases is still a great challenge in condensed-matter systems. The bottleneck has been the ability to adiabatically drive an electron coherently across a large portion of the Brillouin zone in a solid where the scattering ...

Stress Direction Measurement Based on Polarization State in Optical Fibers Using the Quaternion Method

IEEE Photonics Journal, 2017
The state of polarization (SOP) in a polarization-maintaining fiber subjected to external stress is studied using the quaternion method. The stress principal axis on the Poincare sphere is independent of intrinsic birefringence, but has a linear ...

Porous Hybrid Soft Actuators From Liquid Crystal Networks and Lyotropic Chromonic Liquid Crystal Templated Hydrogels

Advanced Materials, EarlyView.
The graphic illustrates the design of a hybrid bilayer composed of a liquid crystal hydrogel (LCH) and a liquid crystal network (LCN). The figure highlights the magnetic alignment of the chromonic hydrogel and the thermal‐responsive actuation of the LCN along with the LCH when both layers are aligned or misaligned, enabling programmable, light‐driven ...

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.

Multifunctional Oxadiazole‐Based Polycatenars: A Pathway to Polar Columnar Phases

Advanced Materials Interfaces, EarlyView.
Aromatic core fluorination directs oxadiazole‐based polycatenars into ferroelectric and antiferroelectric columnar phases with supergelation and photo‐responsiveness. ABSTRACT Polar columnar liquid crystals (LCs) offer a promising pathway to nanostructured architectures for next‐generation ferroelectric devices.
