Dense Nanofibrillar Collagen–Silica Hybrids with High Strength and ECM‐Mimetic Tissue Integration

Advanced Functional Materials, EarlyView.
Dense nanofibrillar collagen–silica hybrids are engineered by synchronizing collagen fibrillogenesis with silica condensation, producing printable scaffolds that unexpectedly approach native extracellular matrix organization and strength. These cell‐free constructs guide endogenous cell‐infiltration, enable localized matrix remodeling, and integrate ...

Highly Birefringent, Low-Loss, and Near-Zero Flat Dispersion ENZ Based THz Photonic Crystal Fibers

IEEE Photonics Journal, 2020
In this paper, we present and compare two experimentally feasible photonic crystal fiber (PCF) designs ($\textit{Type-I}$ and $\textit{Type-II}$) which ensure near-zero flattened dispersion with ultra-high phase and group birefringence at THz frequencies.

ACOUSTIC BIREFRINGENCE AT ELECTROMAGNETIC EXCITATION OF SOUND IN IRON BORATE CRYSTALS [PDF]

Радиофизика и электроника, 2016
High temperature antiferromagnets such as iron borate, hematite etc., have high magnetoelastic coupling. As a result, in the conditions of birefringence effect, there is a possibility to control parameters of sound waves by a small external magnetic ...

Temperature and Strain Sensitivities of High-Birefringence Elliptical Fibers [PDF]

, 1992
We have analyzed and calculated the temperature and strain sensitivities of a high-birefringence double-clad elliptical fiber. We propose a method to minimize these sensitivities without increasing the fiber size or weight; this is achieved by selecting ...

Harnessing the Orientation of Columnar Discotic Liquid Crystals for Narrowband Blue Emission with Enhanced Out‐Coupling Efficiency Toward Improvement of SP‐OLEDs Performance

Advanced Functional Materials, EarlyView.
Solution‐processed OLEDs containing discotic liquid‐crystalline MR‐TADF emitters are reported. Supramolecular self‐assembly induces homeotropic columnar alignment, enforcing preferential horizontal orientation of the emitter transition dipole moment in spin‐coated films, which leads to an enhancement in the device light outcoupling efficiency while ...

Cooling-Rate Induced Fiber Birefringence Variation In Regenerated High Birefringent Fiber

, 2015
In this paper, we have reported birefringence manipulation in regenerated high birefringent fiber Bragg grating (RPMG) by using CO2 laser annealing method. The results indicate that the birefringence of RPMG remains unchanged after CO2 laser annealing followed by slow cooling process, but reduced after fast cooling process (~5.6×10-5).
