Advanced Functional Materials, EarlyView.We present a tissue‐stimulator platform for seamless electrode integration with pancreatic tissue, applying uniform electrical stimulation through optimized design with biohybrid 3D printing. Advantageous effects of electrical stimulation on β‐cell function were observed, including enhanced calcium signaling, islet morphology, and maturation.

Effects of vibrational nonequilibrium on the inviscid design of an axisymmetric nozzle for hypersonic flow [PDF]
An axisymmetric, hypersonic nozzle for arc-heated air is described. The method of characteristics is used to compute an inviscid nozzle contour in which vibrational nonequilibrium is approximated by the sudden-freeze technique.

Biocompatible but Antibacterial Mechanism of Graphene Oxide for Sustainable Antibiotics
Advanced Functional Materials, EarlyView.Graphene oxide (GO) exhibits selective antibacterial activity through specific interactions between its oxygen functional groups and bacterial membrane phospholipid POPG, causing membrane destabilization while maintaining biocompatibility. Model membrane studies and infected wound models in mice and pigs demonstrate effective bacterial suppression and ...

Aerodynamic performance of flared fan nozzles used as inlets [PDF]
Tests were conducted in a low speed wind tunnel to determine the aerodynamic performance of several flared fan nozzles. Each of the flared nozzles was a downstream-facing inlet to a model fan that was used to simulate a variable pitch fan during reverse ...

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 ...

Tracing Sub‐Monolayer Contamination on Wafer‐Scale 2D Materials
Advanced Functional Materials, EarlyView.Sub‐monolayer adventitious carbon contamination limits the performance and reproducibility of 2D material‐based devices. This study demonstrates scanning helium microscopy (SHeM) as a non‐destructive, ultra‐sensitive tool for wafer‐scale imaging of surface cleanliness.
