Colloidal Heterostructures Enable Interfacial Transport of Immiscible Molecules in Printable Organohydrogels

Advanced Materials, EarlyView.
Multiphase printable organohydrogels with tunable microstructures are developed to control molecular transport pathways for immiscible cargo. The tortuosity and domain size of the colloidal phases are tuned by adjusting temperature and shear during processing, which enables the tailoring of diffusion kinetics due to different transport pathways.

Proper Motion and Secular Variations of Keplerian Orbital Elements

Frontiers in Astronomy and Space Sciences, 2018
High-precision observations require accurate modeling of secular changes in the orbital elements in order to extrapolate measurements over long time intervals, and to detect deviation from pure Keplerian motion caused, for example, by other bodies or ...

Origin of rotational kinematics in the globular cluster system of M31: A new clue to the bulge formation

, 2009
We propose that the rotational kinematics of the globular cluster system (GCS) in M31 can result from a past major merger event that could have formed its bulge component.

Influence of Micropillar Height Modulation on Droplet Evaporation and Wetting State Transitions

Advanced Materials Interfaces, EarlyView.
Controlling droplet evaporation dynamics is crucial across many fields. Here, it demonstrates laser‐fabricated polymer micropillar arrays with tailored height variations to regulate evaporation behavior. While all arrays exhibit superhydrophobic wetting, their distinct height profiles effectively slow evaporation and alter evaporation modes ...

The old and heavy bulge of M31 I. Kinematics and stellar populations

, 2009
We present new optical long-slit data along 6 position angles of the bulge region of M31. We derive accurate stellar and gas kinematics reaching 5 arcmin from the center, where the disk light contribution is always less than 30%, and out to 8 arcmin ...

Hygromnemics: Programmable Material Memory Matter Actuators via Wet Pre‐Constraining

Advanced Materials Technologies, EarlyView.
Humidity‐based pre‐constraining creates hygromnemics‐shape memory matter. From identical biocomposites actuation in dry and wet states is obtained via hygromnemic and hygromorphic actuation, respectively. Hygromnemic actuators present long‐ and short‐term shape memory abilities.

Wireless, 3D Optical Sensor Fabricated Using Mechanical Buckling for Navigation and Agriculture Applications

Advanced Materials Technologies, EarlyView.
This study develops a 3D optical sensor formed by mechanical buckling and equipped with wireless communication for navigation. Off‐the‐shelf electronic components are assembled onto a flexible circuit board, followed by mechanical strain‐guiding, facilitating the integration of an out‐of‐plane sensing configuration with a signal processing module. This

The molecular H2 emission and the stellar kinematics in the nuclear region of the Sombrero galaxy

, 2015
We analyze the molecular H$_2$ emission and the stellar kinematics in a data cube of the nuclear region of M104, the Sombrero galaxy, obtained with NIFS on the Gemini-north telescope.
