Chiral Microneedle Arrays With Terahertz Chiroptical Activity With Chiral‐Plasmon‐Chiral‐Phonon Resonance

Advanced Materials, EarlyView.
ABSTRACT Microneedle arrays (MNAs) is a rapidly emerging technology with broad biomedical applications in drug delivery and biosensing. With sub‐millimeter dimensions and periodicity, MNAs possess geometries nearly ideal for biomedical devices operating within the terahertz (THz) spectral window.

Clustomesogen Showing Sub‐Zero Liquid Crystal Properties: Supramolecular Assembly Between Cs2[Mo6Ii8(OCOC2F5)6] and Hexaethylenoxide Containing Mesogenic Dimers

Advanced Materials, EarlyView.
Associating a red‐NIR phosphorescent octahedral hexanuclear molybdenum cluster compound with hexaethyleneoxide chains bearing mesogenic units on both ends leads to an emissive hybrid liquid crystal showing mesomorphism on a very unusual temperature range down to −25°C.

High Birefringence Fluoro-Terphenyls for Thin-Cell-Gap TFT-LCDs

, 2011
Two series of high birefringence fluoro terphenyl compounds are investigated. A binary mixture M1, instead of each individual compound, is found to have predictable properties when mixed with other host mixtures.

Effect of Laser Polarization on Fiber Bragg Grating Fabry-Perot Interferometer for Ultrasound Detection

IEEE Photonics Journal, 2020
High-finesse fiber Bragg gratings (FBGs) Fabry-Perot interferometers (FPIs) have shown great promise as sensitive ultrasonic sensors. However, the fabrication process of the sensors usually introduces birefringence to the fiber, which makes the sensor ...

Self‐Seeded Nucleation of PET in a Benign Solvent Yields a High Modulus Aerogel With Ultra‐Low Thermal Conductivity

Advanced Materials, EarlyView.
A new benign solvent (1,3‐diphenylacetone) enables a simple, safe, and sustainable dissolution and gelation method to convert waste PET into low density, monolithic aerogels with high mechanical strength (E = 20 MPa) and remarkably low thermal conductivity (k = 21.9 to 28.9 mW/m·K).

High birefringence and low viscosity negative dielectric anisotropy liquid crystals

, 2008
We have synthesised and evaluated the physical properties of some high birefringence, lateral difluoro-terphenyl compounds and mixtures. These mixtures exhibit a high birefringence (n0.24) in the visible spectral range and a relatively low viscosity ...

Full Vectorial Field Sensing Using Liquid Crystal Droplet Arrays

Advanced Materials, EarlyView.
An inkjet‐printed liquid crystal droplet array enables compact, low‐cost, single‐shot sensing of the full vectorial light field. Within a single platform, it simultaneously retrieves intensity, polarization, and phase, while dual‐wavelength operation highlights its capability for multi‐wavelength optical field characterization. ABSTRACT Determining the

Monitoring the Etching Process of Hi-Bi Fiber Through a Fiber Loop Mirror

IEEE Photonics Journal, 2017
A method for monitoring the etching process of Hi-Bi fiber is proposed and demonstrated. The birefringence of the etching fiber is accurately calculated by tracking the shift of the interference spectrum in a high-birefringence fiber loop mirror ...

Circular hole ENZ photonic crystal fibers exhibit high birefringence [PDF]

, 2018
A novel photonic crystal fiber (PCF) design that yields very high birefringence is proposed and analyzed. Its significantly enhanced birefringence is achieved by filling selected air holes in the cladding with an epsilon-near-zero (ENZ) material ...

Hierarchical Structure and Fabrication of Functionally Graded Biointerfaces in the Mussel Byssus

Advanced Materials Interfaces, EarlyView.
The byssus is a fibrous protein‐based holdfast consisting of mechanically distinct interfaces, which mussels use to anchor their soft living tissue to hard seashore surfaces. Here, multiscale methodologies were used to elucidate the compositional and structural features underlying these functionally graded interfaces and how they are fabricated through
