Hydrocolloid‐Based Multiwavelength Stretchable QD‐OLED Patch for Simultaneous Neonatal Jaundice and Dermatitis Treatment with Biosignal Monitoring

Advanced Healthcare Materials, EarlyView.
Comparison of therapeutic and diagnostic applications of a surface‐emitting light source with multiwavelength emission characteristics. Abstract Conventional light‐emitting‐diode‐based light sources suffer from rigidity, localized heating, and poor adaptability to skin deformation, limiting their use in skin‐attached medical devices.

Aqueous Two‐Phase Bioinks for Discrete Packing and Compartmentalization of 3D Bioprinted Cells

Advanced Healthcare Materials, EarlyView.
Aqueous two‐phase systems (ATPS) enable the formation of biomimetic interfaces crucial for tissue engineering. However, clinical translation remains limited by the challenge of precisely controlling cellular compartmentalization. Here, we developed ATPS biomaterial inks for 3D bioprinting allowing tuneable droplet formation via NaCl modulation.

The Floor‐Ceiling‐Chip, or 2 × 2D = Pseudo‐3D—Approaching 3D Cell Morphology and Organization between Two Opposing 2D Substrates with Cell‐Adhesive Protein Micropatterns

Advanced Healthcare Materials, EarlyView.
Here, we present a novel 3D cell patterning and culture platform. The “Floor‐Ceiling‐Chip” (FC‐Chip) consists of two opposing track‐etched membranes, creating a pseudo‐3D microenvironment for the cells in between. By providing the membranes with micropatterned cell‐adhesive islands of varying geometries and sizes, the FC‐Chip enables control over cell ...

Optical anisotropy of (311) superlattices

Physical Review B, 1994
We report a calculation of the electronic properties of GaAs/AlAs (311) superlattices through the Brillouin zone using realistic values of the parameters in a tight-binding Hamiltonian. The nature and the localization of the lowest conduction bands for these low-symmetry structures is investigated and its origin is studied with respect to the layer ...

Optical anisotropy of UNi2Si2

Physica B: Condensed Matter, 1993
Abstract The optical anisotropy of UNi 2 Si 2 has been systematically studied by reflectance spectroscopy in the range of 50 to 37 000 cm -1 . A temperature-dependent absorption peak was found in the c -axis optical conductivity spectra centered at 280 cm -1 in the incommensurate longitudinal spin-density-wave phase (103 K T K ), which, we ...

Optical anisotropies in electromodulation

SPIE Proceedings, 1990
We describe both reflectance anisotropy and electroreflectance measurements carried out to determine the physical origin of the anisotropies observed in the reflectance spectrum of (001) and (110) GaAs. We find an anisotropy component which depends on impurity concentration for both (001) and (110) surfaces [and on conductivity type for (001) GaAs].
