Magnetically Actuated Drops‐on‐Stilts Microrobots for Transport and Delivery of Hydrophobic Cargo

Advanced Materials Interfaces, EarlyView.
Iron oxide nanoparticles and oil droplets in external magnetic fields form “drops‐on‐stilts” microrobots that transport hydrophobic cargo. Tunable nanoparticle–droplet interactions generate stilt‐like structures. Field rotation enables walking, obstacle navigation, and collective motion.

The Palomar Kernel Phase Experiment: Testing Kernel Phase Interferometry for Ground-based Astronomical Observations

, 2015
At present, the principal limitation on the resolution and contrast of astronomical imaging instruments comes from aberrations in the optical path, which may be imposed by the Earth's turbulent atmosphere or by variations in the alignment and shape of ...

The Role of Self-gravity in Debris-disk Warp Formation: The Case of HD 110058

The Astrophysical Journal Letters
We investigate the crucial role of self-gravity in the formation of warps in debris disks, focusing on the HD 110058 system as an example. Using advanced graphical-processing-unit-accelerated N -body simulations, we model the gravitational dynamics of a ...

CHINESE ANTARCTIC ASTRONOMICAL OPTICAL TELESCOPES

Revista Mexicana de Astronomía y Astrofísica Serie de Conferencias, 2019
Due to its superb seeing conditions, the Antarctica plateau is widely considered to be an excellent astronomical site. The long periods of uninterrupted darkness at polar sites such as Dome A provide a possibility of continuous observation for more than three months, which is quite suitable for time-domain astronomy.
