Color Alleviation in Hybrid Electrospun‐Electrosprayed Magnetic Paper
Macromolecular Rapid Communications, EarlyView.A combined electrospinning/electrospraying fabrication approach enables the chromatic alleviation of the brown Color of Fe3O4 nanoparticles, by encapsulating them within polymer‐based electrosprayed microparticles that are sandwiched between electrospun fibrous layers.

Cross‐Platform Demonstration of an Autonomous MRI Field Camera
Magnetic Resonance in Medicine, EarlyView.Purpose Recent work has proposed self‐synchronization, self‐calibration, and means of sequence parsing to enhance the versatility of field cameras. The purpose of this paper is to expand this approach to more complex sequences and verify feasibility across distinct scanner platforms.
