An Examination of Aerosol Jet‐Printed Surface Roughness and its Impact on the Performance of High‐Frequency Electronics

open access: yesAdvanced Engineering Materials, EarlyView.
This study explores aerosol jet‐printed (AJP) surface roughness, its effects on the performance of microwave electronics, and its process contributors. First, an electromagnetic model is vetted for AJP's unique roughness signature. Simulations are built which show process‐induced roughness is as significant as conductor resistivity in driving microwave

Fluorinated Graphene‐Coated N95 Respirators for Enhanced Protection against Viral Accumulation and Transmission

open access: yesAdvanced Engineering Materials, EarlyView.
We develop a one‐step spray coating approach to coat the fluorinated graphene (FG) nanosheet onto the N95 respirators. The spray‐coated superhydrophobic N95 respirators can effectively repel respiratory droplets off instantaneously and prevent SARS‐CoV‐2 virus accumulation on the surface.

Scalable Manufacturing of Radiation‐Tolerant Potentiometric Electrodes: A Systematic Transition from Laboratory to Semiautomated Fabrication

open access: yesAdvanced Engineering Materials, EarlyView.
Laboratory protocols for producing thin‐film pH electrodes for sterilized single‐use technologies have been successfully developed into a semiautomated workflow, with higher throughput and precision of membrane thickness. Accuracies are within 0.05 pH units versus ground truth, and uncertainty analysis reveals the largest sources of error to be derived

Combining Metal Additive Manufacturing and Casting Technology: High Performance Cooling Channels for Electric Powertrain Components

open access: yesAdvanced Engineering Materials, EarlyView.
When realized as inserts in high‐pressure die casting, aluminum cooling channels for electric powertrain components and similar applications typically require a stabilizing filler to survive the process. The present study investigates relinquishing this filler using additively manufactured inserts promising performance improvements.

Investigation of Iron‐Aluminide‐Like Phase Composition in Complex Concentrated Fe32Cu12Ni11Ti16Al29 Alloy

open access: yesAdvanced Engineering Materials, EarlyView.
This work reveals the phase composition and quantitative morphology analysis of precipitation‐hardened Fe32Cu12Ni11Ti16Al29 complex‐concentrated alloy. The precipitates are shown to have a high coherency. Morphology transition between sphere, cuboidal, and elongated morphology is observed. Finally, the overaging behavior is captured using microhardness.
