“Three‐Color” Chemical Selectivity between Oxide, Nitride, and Silicon: Area‐Selective Deposition of Metal Oxide and Polymer on SiN and Si‐H versus SiO2

open access: yesAdvanced Materials Technologies, EarlyView.
Molybdenum hexafluoride as a pretreatment is able to create a chemical contrast between SiN and SiO2 surfaces via selective fluorine passivation of the oxide. One dose of MoF6 enabled 9.7 nm of selective deposited TiO2 on SiN versus SiO2 with selectivity >0.92 on a nanoscale SiN/SiO2 patterned surface.

How to Manufacture Photonic Metamaterials

open access: yesAdvanced Materials Technologies, EarlyView.
Metamaterials boast applications such as invisibility and “hyperlenses” with resolution beyond the diffraction limit, but these applications haven’t been exploited in earnest and the market for them hasn’t grown much likely because facile and economical methods for fabricating them without defect has not emerged.

Configurable 3D‐Printed Microstructured Stamp as a User‐Friendly Tool for Versatile Patterning of Low‐Viscosity Bioinks

open access: yesAdvanced Materials Technologies, EarlyView.
A technique for precise patterning of highly biocompatible, low‐viscosity bioinks, such as fibrin, is crucial for recapitulating the physical organization of tissues. In this study, a configurable 3D‐printed microstructured stamp with micropillars is used to control the spatial arrangement of low‐viscosity bioinks and to assess cellular interactions ...
