Functional Polymer Nanocomposites by Gas Aggregation Cluster Source and Initiated Chemical Vapor Deposition

Advanced Materials Technologies, EarlyView.
In this work, a gas aggregation cluster source and an initiated chemical vapor deposition are combined in a single vacuum reactor. With this setup polymer thin films can be combined with functional nanoparticles. As a proof‐of‐concept PTFE is combined with silver nanoparticles and tested in antibacterial, antiviral, and anticancer applications ...

Omnidirectional and Multi‐Material In Situ 3D Printing Using Acoustic Levitation

Advanced Materials Technologies, EarlyView.
An acoustophoretic 3D fabrication system enabling omnidirectional, multi‐material in situ printing is presented via acoustic levitation. Utilizing a phased array of transducers (PAT), it generates acoustophoretic forces for levitating and transporting materials in mid‐air, allowing precise, contactless, and voxel‐by‐voxel printing onto complex ...
