Programmable Pneumatic Actuator System for a Bioinspired Artificial Colon
Advanced Materials Technologies, EarlyView.A modular soft robotic colon simulator driven by programmable pneumatic actuation is developed to mimic physiological and pathological‐like motility patterns of the large intestine. Finite element–guided design and distributed control enable anatomically realistic deformation for peristalsis, segmentation, and mass movements, supporting capsule ...

Brightness and shape of radio jets
The Astrophysical Journal, 1979 Observed radio structures of jets in radio galaxies are compared with models based on beam and slingshot theories. Simple beam models predict a rapid decline of surface brightness B with distance r from the nucleus, Bproportionalr/sup -m/, where m>3. This contrasts with the almost uniform brightness out to 200 kpc in the jet of NGC 6251 and out to 10 ...

Defect‐Engineered ZnO Nanowire Arrays for Flexible Room‐Temperature Hydrogen Sensors
Advanced Materials Technologies, EarlyView.Fabrication process of patterned ZnO nucleation sites on a flexible polyimide (PI) substrate. Top/tilted‐view SEM images of ordered ZnO nanoflower arrays confined within patterned circular regions. AFM topography map with height data revealing a disk‐array structure, where the patterned regions (marked by a red dot circle) are elevated by ∼2 µm ...

The bulk kinetic power of radio jets in active galactic nuclei？
, 2009 Based on the Konigl's inhomogeneous jet model, we estimate the jet parameters, such as bulk Lorentz factor Gamma, viewing angle theta and electron number density n(e) from radio very long-baseline interferometry and X-ray data for a sample of active ...

Microfabrication of Soft Millirobots Propelled by Low Voltage Electrohydraulic Actuators
Advanced Materials Technologies, EarlyView.Manual layer‐by‐layer assembly is replaced by wafer‐level MEMS batch fabrication for compliant polymer‐based electrohydraulic actuators. The microfabricated devices integrate sacrificially defined microcavities, Parylene‐C‐sealed inlets, and multilayer polymer–metal films.
