Modulation of Lanthanide Luminescence with the Mechanical Bond: Antenna‐Emitter Confinement in a Compact [2]Rotaxane

open access: yesAngewandte Chemie International Edition, Accepted Article.
Luminescent emitters based on lanthanide ions are of ubiquitous importance in the biological sciences, but typically need sensitisation from a covalently attached adjacent chromophore – an “antenna” – to have suitable emission intensities. Here we show that the mechanical bond can be used to connect the antenna to the emitter, providing unique dynamic ...

A Comparative Study on Friction Performance and Mechanical Properties of Printed PETG Materials With Different Patterns

open access: yesJournal of Applied Polymer Science, EarlyView.
ABSTRACT Investigating the mechanical and wear properties of widely used PETG (polyethylene terephthalate glycol) filaments is important to understanding the material's performance, reliability, and suitability in different application areas. This study performed tensile and wear tests on PETG samples produced with a 3D printer using four infill ...

Moving From Micro‐ to Nanofibers Within Melt Electrospinning

open access: yesJournal of Applied Polymer Science, EarlyView.
Controlling flow rate enables production of more nanofibers. This can be achieved even when electrospinning from viscous melts in a simple two‐plate geometry. Finding the optimal melt thickness to reduce flow without lowering the number of fiber‐forming jets is key.
