Cortical Response to Acute Implantation of the Utah Optrode Array in Macaque Cortex

open access: yesAdvanced Healthcare Materials, EarlyView.
Delivering light deep into the brain over a large volume while causing minimal tissue damage is a major challenge for non‐human primate optogenetics. This study evaluates Utah Optrode Array designs in vivo, revealing how changes in shank geometry, surface texture, and insertion parameters minimize acute damage—offering a path toward high‐precision ...

Co‐Electrospinning Extracellular Matrix with Polycaprolactone Enables a Modular Approach to Balance Bioactivity and Mechanics of a Multifunctional Bone Wrap

open access: yesAdvanced Healthcare Materials, EarlyView.
The incorporation of nondigested ECM and synthetic polymers into a co‐electrospinning system enables the decoupling of bioactivity and mechanical properties within a single wrap. This technique is used to develop a multifunctional bone wrap that achieves augmented membrane durability, sustained infection control, and enhanced vascularity for use in ...

Supersonic Jet Excitation using Flapping Injection

open access: yes, 2013
Supersonic jet noise reduction is important for high speed military aircraft. Lower acoustic levels would reduce structural fatigue leading to longer lifetime of the jet aircraft. It is not solely structural aspects which are of importance, health issues

Controlling Intestinal Organoid Polarity using Synthetic Dynamic Hydrogels Decorated with Laminin‐Derived IKVAV Peptides

open access: yesAdvanced Healthcare Materials, EarlyView.
Design rules are presented to control intestinal organoid polarity in fully synthetic hydrogels. The laminin‐derived IKVAV sequence is crucial to obtain correct intestinal organoid polarity. Increasing hydrogel dynamics further supports the growth of correctly polarized intestinal organoids, while a bulk level of stiffness (G’ ≈ 0.7 kPa) is crucial to ...

A photon breeding mechanism for the high-energy emission of relativistic jets

open access: yes, 2006
We propose a straightforward and efficient mechanism for the high-energy emission of relativistic astrophysical jets associated with an exchange of interacting high-energy photons between the jet and the external environment.
