Influence of a Hydrogen Addition to the Inert Gas and Subsequent Heat Treatments on the Microstructure and Mechanical Properties of Magnesium WE43 Fabricated by PBF‐LB/M

open access: yesAdvanced Engineering Materials, EarlyView.
This article investigates optimal processing conditions for the laser‐based powder bed fusion of WE43. To limit the interaction with remaining oxygen, a 3 vol% hydrogen admixture to the inert gas is investigated. Furthermore, heat treatments are investigated in the range of 250–350 °C for 48 h.

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.
