A review of Hall thruster plume modeling [PDF]
38th Aerospace Sciences Meeting and Exhibit, 2000 Hall thrusters are an attractive form of electric propulsion that are being developed to replace chemical systems for many orbit propulsion tasks on communications satellites. A concern in the use of these devices is the possible damage their plumes may cause to the host spacecraft.

Rotating Fluorescent Nanodiamond Assemblies With Focused Laguerre–Gaussian Beams
Advanced Optical Materials, EarlyView.Self‐assembled fluorescent nanodiamond clusters are optically trapped and driven into controlled two‐dimensional rotation with Laguerre–Gaussian beams. With localized optical excitation, optically detected magnetic resonance spectra are collected at defined points along the orbit in a uniform external magnetic field.

Molecularly Templated Buried Interfaces for Inverted Perovskite Solar Cells
Angewandte Chemie, EarlyView.We demonstrate a molecularly matched buried interface between SAM and perovskite, enhancing adhesion and passivating defects. This optimized interface achieves 26.58% power conversion efficiency and 86.72% fill factor with exceptional operational stability in both large‐area and wide‐bandgap devices, thereby increasing efficiency and prolonging ...
