Measurements of angular momentum in jets and outflows, and feedback on the disk
Frontiers in Astronomy and Space SciencesThe problem of understanding how a newly forming solar system manages to lose angular momentum from the stage of collapsing core to the final main sequence phase is a long-standing one.

Embedded Direct Ink Writing of Thermoset and Elastomeric Polymers via Frontal Polymerization
Advanced Functional Materials, EarlyView.Embedded frontal polymerization direct ink writing (FP‐DIW) combines frontal ring‐opening metathesis polymerization with embedded 3D printing to decouple deposition from curing. A yield‐stress support bath stabilizes low‐viscosity inks, while on‐demand thermal initiation enables controlled front propagation. This approach expands the accessible feature

The Correlation between the Total Magnetic Flux and the Total Jet Power
Frontiers in Astronomy and Space Sciences, 2017 Magnetic field threading a black hole ergosphere is believed to play the key role in both driving the powerful relativistic jets observed in active galactic nuclei and extracting the rotational energy from a black hole via Blandford-Znajek process.
