Loading Mode Dependence of Twin‐Twin Boundary Formation in a Textured Magnesium Alloy

open access: yesAdvanced Materials Interfaces, EarlyView.
The structures of twin‐twin boundaries formed by interactions between twin variants sharing the same or different zone axes in a deformed magnesium alloy are demonstrated. Lattice distortion around complicated interfaces promotes grain refinement in the subsequent thermomechanical process, enhancing the mechanical performance of magnesium alloys ...

Multiparameter Closed‐Loop Control to Advance Reliability of Aerosol Jet Printing

open access: yesAdvanced Materials Technologies, EarlyView.
A multiparameter framework for closed‐loop control of aerosol jet printing is developed to improve process consistency over both short and long timescales. By creating a control architecture responsive to the dynamic behavior of the printing system, variability in functional electrical properties is significantly reduced over extended duration printing,

Electroluminescence and Franz–Keldysh Modulation Observed in Sn/Ge Multi‐Quantum Wells

open access: yesAdvanced Optical Materials, EarlyView.
We investigate the optoelectronic properties of PIN diodes based on ultrathin α‐Sn/Ge multiple quantum film structures, fabricated by molecular beam epitaxy, both experimentally and theoretically. The samples exhibit a light emission spectrum in the short‐wavelength infrared range with two transitions. Furthermore, when operating as a photodetector, we

Reducing Personalization Time and Energy Cost While Walking Outdoors with a Portable Exosuit

open access: yesAdvanced Robotics Research, EarlyView.
Rapid Real‐World Optimization! An AF‐based human‐in‐the‐loop optimization strategy rapidly personalizes a portable hip extension exosuit for incline walking. Real‐time Bayesian optimization of assistive force significantly reduces metabolic energy—up to 16.2%—while converging in just 3 min 24 s.
