Virtual Draw of Tubular Hollow-Core Fibers [PDF]

Frontiers in Optics / Laser Science, 2018
A numerical model that accurately predicts the fabricated geometry of tubular hollow-core fibers is presented and experimentally validated. Such a model can be invaluable in driving design decisions for yield upscaling and loss reduction.

Dispensing Volumetric Additive Manufacturing

Advanced Functional Materials, EarlyView.
Dispensing volumetric additive manufacturing (DVAM) prints 3D structures inside a photocurable resin droplet suspended from the tip of a glass pipette, enabling sequential printing without resin vats or manual part removal. Real‐time droplet profiling and ray‐tracing‐based correction compensate for optical distortion at the curved resin‐air interface ...

Low-loss Multimoded Antiresonant Hollow Core Fiber

14th Pacific Rim Conference on Lasers and Electro-Optics (CLEO PR 2020), 2020
We report the first design for low-loss, multimoded antiresonant hollow-core fiber for applications requiring multiple modes. The designed fiber guides 6 - 9 spatially distinct core modes having confinement loss <0.001 - 0.01dB/m respectively.

Engineering Strategies for Stable and Long‐Life Alkaline Zinc‐Based Flow Batteries

Advanced Functional Materials, EarlyView.
Alkaline zinc‐based flow batteries face persistent challenges from unstable zinc deposition, including dendrite growth, passivation, corrosion, and hydrogen evolution, which severely limit cycling stability. Current research addresses these issues through coordinated electrode structuring, electrolyte regulation, and membrane design to control zinc ...

Assembly of Cell‐Seeded 3D Printed Hydrogel Modules with Perfusable Channel Networks

Advanced Functional Materials, EarlyView.
Macroscale assembly was utilized to prepare perfusable tissue constructs from individually 3D printed hydrogel modules with embedded branched channel networks and port arrays for cell seeding. Novel multi‐material bioreactors were fabricated to facilitate the gluing of individual modules and the perfusion culture of assembled modular constructs seeded ...
