Controlled Growth of Boron Nitride in Various Phases

open access: yesAdvanced Materials Interfaces, EarlyView.
Phase‐selective boron nitride growth is presented as a unified materials‐design problem across hexagonal, rhombohedral, cubic, and amorphous phases. By linking synthesis routes to thermodynamic stability, kinetic accessibility, surface diffusion, interfacial templating, and energetic activation, this review clarifies how bonding and stacking are ...

Programmable Crack Networks for Wide‐Range and Reversible Strain Sensing in Vertically Oriented van der Waals Molybdenum Disulfide Thin Films

open access: yesAdvanced Materials Technologies, EarlyView.
Vertically oriented van der Waals MoS2 thin films enable a mechanically programmable crack network for strain sensing. The initial mechanical programming protocol establishes a programmed crack configuration along weak interlayer and interdomain interfaces.

A State‐Adaptive Koopman Control Framework for Real‐Time Deformable Tool Manipulation in Robotic Environmental Swabbing

open access: yesAdvanced Robotics Research, EarlyView.
This work presents a state‐adaptive Koopman linear quadratic regulator framework for real‐time manipulation of a deformable swab tool in robotic environmental sampling. By combining Koopman linearization, tactile sensing, and centroid‐based force regulation, the system maintains stable contact forces and high coverage across flat and inclined surfaces.

Delta Parallel Robot Based on Crank-Slider Mechanism [PDF]

open access: yes, 2017
A three-degree-of-freedom Delta parallel manipulator driven by a crank-slider mechanism is proposed. In Cartesian space, a gate-shaped curve is taken as the path of the pick-and-place operation, combining with the inverse kinematics theory of the Delta ...
