Biomimetic Nanofiber Scaffold Coated With Acellular Matrices for Uterine Myometrial Tissue Engineering

Advanced NanoBiomed Research, EarlyView.
Schematic representation of acellular matrix generation from human uterine fibroblast cells, coating on polycaprolactone electrospun nanofibers, and subsequent in vitro and in vivo characterization. A tissue‐engineered scaffold tailored for uterine myometrium‐specific regeneration is designed. The electrospinning technique was used to fabricate aligned

Talbot interference of whispering gallery modes

APL Photonics
The Talbot self-imaging phenomenon is a fundamental interference effect that is natural to all waves with a periodic structure. We theoretically and experimentally study the Talbot effect for optical waves in the transverse angular domain using ...

Compositionally Engineered Carboxymethyl Cellulose‐Based Optical Fibers With Exceptionally Low Optical Loss and Quantitative Humidity Sensing

Advanced Physics Research, EarlyView.
Carboxymethyl cellulose‐based biopolymer optical fibers are fabricated using aqueous wet spinning. The fibers exhibit record‐low optical attenuation in polysaccharide‐based waveguides while maintaining efficient transmission across the visible‐to‐near‐infrared region of the electromagnetic spectrum.

Silicon-on-insulator based 2 x 2 multimode interference coupler with large tolerance

, 2001
We demonstrate a type of 2 x 2 multimode interference 3 dB coupler based on silicon-on-insulator. The fabrication tolerance was investigated by the effective index method and the guide mode method.

Mid-infrared photonics devices in SOI

In this paper we present silicon photonics devices designed for the 3-4µm wavelength region including waveguides, MMIs, ring resonators and Mach-Zehnder interferometers. The devices are based on silicon on insulator (SOI) platform. We show that 400-500nm

Stable, Reusable Copper‐Bispidine Catalysts on Agarose With Diffusion‐Limited Turnover: When Immobilization is not Covalent

European Journal of Inorganic Chemistry, EarlyView.
Epoxy‐activated agarose beads as support for copper(II)‐bispidine complexes provide reusable heterogeneous catalysts for styrene aziridination with negligible copper leaching. Immobilization occurs largely through noncovalent interactions. Catalyst loading strongly governs performance by balancing active‐site density, accessibility, and mass transport.

Study on the internal reflection of the multimode-interference-type device

, 2004
The internal reflection of the multimode-interference (MMI)-type device is calculated with the bidirectional beam propagation method. The calculated results indicate that the difference of the effective refractive indices between the core region and the ...
